Which is better, a window air conditioner or a separate split system - 5 factors in favor of choosing a monoblock

For those home owners who cannot afford to buy expensive climate control equipment, I suggest installing a monoblock window air conditioner in a plastic window. It will cost much less, and its installation will be easy to do independently, without significant financial costs. For those who doubt it, I will give reasons in favor of this decision.

Factor 1. The operating principle of a window air conditioner

All compressor-type air conditioners operate on the principle heat pump , which, in temperature reduction mode, transfers heat from the cooled room to the street. As a working substance in such pumps, special refrigerants (freons) are used, which, depending on the operating pressure and temperature, can be in a liquid or gaseous state.

Window-type air conditioners work on the same principle, so inside they are divided by a sealed partition into two isolated parts, one of which is located outside the window, and the second inside the room. An electric compressor, a condenser and an electric fan motor are installed in the outer part, and an evaporator, a circulation fan impeller and the electronic unit management.

1. After turning on the air conditioner, gaseous freon is compressed 5-6 times under the action of the compressor and enters the condenser, warming up to a temperature of 60-90°C;
2. The condenser is a flow coil made of finned copper or brass tubes, due to which it has a large heat transfer surface. Thanks to this, the compressed and heated freon quickly cools down, giving off its heat to the surrounding space (outside), and turns into a liquid state of aggregation;

1. Liquid freon passes through a throttle valve, which has a very small cross-section, and through a system of tubes enters the evaporator, which is installed in the inside of the air conditioner;
2. Inside the evaporator, liquefied freon enters a space with a large volume, so it expands sharply, as a result of which it turns from a liquid state into a vapor.
3. The evaporation process is accompanied by strong heat absorption and release large quantity cold, so the evaporator is cooled to a very low temperature (-12°C to -24°C);
4. After this, the evaporated freon, under the influence of vacuum, again enters the compressor, and the entire described cycle is repeated again;

1. Inside the window air conditioner there is an electric motor, which has two fan impellers mounted on both sides on one shaft. This electric motor usually turns on at the same time as the compressor starts;
2. The impeller of the outdoor unit blows on the condenser during operation, and thereby promotes better heat removal into the atmosphere and rapid liquefaction of heated compressed freon.
3. The impeller of the indoor unit is designed for forced circulation warm air from the room through a cooled evaporator. Thus, the entire volume of air in the room is gradually cooled and transfers its heat through the refrigerant to the outdoor unit of the air conditioner.

Factor 2. Additional functions of window air conditioners

Despite its name, a modern window air conditioner is designed for more than just cooling air. Thanks to the built-in additional functions, it can constantly maintain optimal indoor climate parameters. In ventilation mode, it can perform the function of forced supply or exhaust ventilation.

Some models of inverter air conditioners, in addition to cooling, also have a heating function, so in the warm season they can cool the room, and in the cold season they can operate in heater mode.

1. Built-in touch sensors and an electronic control unit monitor the temperature and humidity of the indoor air, and can turn the air conditioner on or off automatically, depending on the preset settings;

1. In order to ensure ventilation of the room without opening the window, a special window is provided in the dividing partition between the outer and inner parts, which is normally closed with a sealed damper;
2. When the ventilation function is turned on, this damper automatically opens, after which the additional fan motor starts. Depending on the selected mode, it can work as a forced exhaust or as a blower fan;
3. The window heating air conditioner is equipped with absolutely identical interchangeable evaporator and condenser models, which are installed and connected to the compressor symmetrically. The direction of movement of the refrigerant, in this case, is set using controlled electromagnetic three-way valves;

1. When the device is operating in room cooling mode, the internal coil acts as an evaporator, and the outer one plays the role of a capacitor. In this case, freon circulates as described in the first section;
2. When the room heating mode is turned on, the solenoid valves redistribute the direction of movement of freon in reverse side. Thus, the outdoor unit with cooled liquid refrigerant takes heat from the street and becomes an evaporator, and indoor unit with heated vapors of compressed freon, gives off heat to the room and becomes a condenser.

Despite the technical characteristics stated by the manufacturer, I do not recommend turning on the heating function for a long time, or using the air conditioner as the main heating device when the air temperature outside the window is below +3°C. The point is that when negative temperatures The viscosity of the engine oil in the compressor increases significantly.
This leads to increased energy consumption, accelerated wear of rubbing parts and premature failure of the compressor unit.

Factor 3. Main advantages and disadvantages

There is a widespread belief among apartment owners that window air conditioners are obsolete and are now practically not used anywhere. From my experience, I can say that this opinion is incorrect, since even now many homeowners opt for such models. This is due to the fact that a built-in window air conditioner has a number of significant advantages over separate split systems:

1. Very often, the main criterion for choosing household appliances is their cost. As I already said, purchasing a monoblock window will cost much less than the cost of purchasing, installing and connecting modern split systems;
2. In most cases, installation of an outdoor unit of a split system must be carried out using an aerial platform or with the involvement of industrial climbers, and such work is very expensive;
3. Taking into account the design features of the split system, refrigerant charging of such air conditioners is carried out at the very end, after installation and connection of the freon line. Refueling must be performed by a qualified specialist, who will also require a certain amount of money for his work;

1. Window or vent monoblocks are sold filled with freon and completely ready for installation, so installing a window air conditioner yourself is not particularly difficult. Installation work is carried out directly from the apartment window, and the absence of an external unit does not require the involvement of industrial climbers;
2. Due to the compact arrangement of components and assemblies, as well as the absence of a long freon line, such devices have higher efficiency, and are characterized by higher maintainability, reliability and durability;
3. Due to the fact that the window monoblock is installed at the junction of the street and the apartment, it easily implements the forced ventilation function, which allows you to quickly and effectively ventilate the room. In a separate split system, it is technically very difficult to implement such a function;

If we talk about which is the best air conditioner to choose for your apartment, then I must draw the readers’ attention to some disadvantages that are inherent in almost all models of window air conditioners:

1. The installation of any air conditioner violates the aesthetics of the building and spoils the appearance of the facade, and the installation of a monoblock window, in addition to this, also blocks part of the light opening of the window;
2. The dividing partition between the outer and inner parts of the air conditioner does not have proper thermal insulation, so in severe frosts it can cause cold penetration into the apartment.
3. The presence of small gaps between the window frame and the air conditioner body, as well as loose closure of the ventilation damper, can become a source of drafts.
4. To reduce the noise level in the room, all electrical components and assemblies (compressor and fan motors) are located in the outer part of the monoblock air conditioner. Despite this, his work is still accompanied by a low monotonous noise, therefore, speaking objectively, split systems are much quieter;

Long curtains and curtains made of thick, thick fabric can prevent normal air circulation through the evaporator of a window air conditioner. To prevent this from happening, curtains and blinds on the windows should be selected in such a length that they do not reach the air intake grilles of the indoor unit.

Factor 4. Features of installation and connection

Despite the fact that the technology for installing a monoblock window may seem quite simple at first glance, when performing such work you will have to redo the double-glazed window and make changes to the design of the window frame. To make it easier for the reader to cope with this task, step-by-step instructions will be described below as an example, in which I will describe in detail the main stages of installing a window air conditioner in a metal-plastic window.

1. First of all, you need to decide where the air conditioner will be located in the window. In my opinion, the most suitable place considered to be the lower part of one of the blind, non-opening sashes;

1. On the selected sash, you need to remove the plastic locking beads. Along the perimeter of the glass sharp knife cut out a layer of silicone sealant, and then carefully dismantle the double-glazed window;
2. Before installing a window air conditioner yourself, you need to supply a power cable with a cross-section of 3x1.5 mm² to the installation site, which must be connected to switchboard to a separate machine of appropriate power;
3. Insert the air conditioner into the window opening freed from glass, and pre-fix it at several points using standard mounting brackets, which are included in the delivery kit;
4. If dimensions If the devices turn out to be smaller than the window opening, then to install it you will need an additional insert with a cutout for the air conditioner, which will be installed between its body and window frame;

1. It can be made from a tough and durable weather-resistant material ( sheet aluminum, thick plastic or bakelized plywood), and then insulate the outside with a layer of extruded polystyrene foam or polyurethane foam with a thickness of at least 50 mm;
2. The insert must be installed in place of the double-glazed unit, coated around the perimeter with silicone sealant, and firmly fixed to the window frame along the entire perimeter using self-tapping screws. It is best to paint it from the inside in the color of the main metal-plastic profile;
3. Above the insert, install and secure a small piece of the lower profile of the window frame, which can be purchased at a fabrication workshop metal-plastic windows;
4. After installing the lower profile of the window opening, you need to take the dimensions for installing the glass, and order the production of a new double-glazed unit from the same workshop, which will be installed above the air conditioner;
5. During final installation of the air conditioner, it should be started from inside the window. The front panel and the inside of the monoblock must be placed inside the cutout in the intermediate insert, and secure it using the mounting brackets without fully tightening the mounting bolts;

1. Using a level and shims, align the front of the air conditioner with respect to the window, and make sure that its body has an inclination in the horizontal plane from the room towards the street by at least 2°;
2. After this you need to connect to the device electrical cable, and do not forget to tighten the mounting bolts to the end, and fill the existing cracks and joints with foam and coat them with silicone sealant for external use;
3. Install a new double-glazed unit in the upper opening of the window above the air conditioner, seal it around the perimeter with silicone sealant, and install locking beads on the metal-plastic profile;
4. As a rule, window air conditioners have a long service life and long term operation, but if you suddenly need to repair the compressor unit or refill the system with freon, then disassembling the window and dismantling the monoblock will need to be done in the reverse order.

In order to after overhaul in the apartment there was no need to redo a new window with your own hands, the purchase of a monoblock air conditioner and the ordering of metal-plastic windows are best done at the same time. At the same time, it is enough to provide the workshop that manufactures windows with the installation dimensions of the air conditioner and indicate where it should be located, and then they will do everything themselves.

Factor 5. Alternative to a monoblock window

If you have a portable mobile air conditioner on wheels in your house, then I advise you to install it next to the windowsill and direct the hot exhaust air from the condenser directly to the window. This will improve its operating efficiency and help reduce electricity consumption., and in addition, it will eliminate the need to lay a thick hose throughout the apartment to release hot air.

In order to carefully route the hose outside, you will need to make a small intermediate insert that will be installed in window frame below the main double-glazed unit.

1. Before installing a floor-standing air conditioner in a plastic window, you need to measure the length and diameter of the hose for removing hot air, and make an insert in accordance with these dimensions;

1. Further steps for making the insert should be performed in exactly the same way as described in the previous section, with the only difference that you do not need to cut a large opening in it for the entire air conditioner, but just make round hole according to the diameter of the outlet plastic hose.
2. A plastic sleeve must be firmly secured in the resulting hole. Place the free end of the air outlet hose on it and secure it with a plastic crimp clamp;
3. When hot air escapes outside, condensation may form in the pipe. To prevent water from flowing back into the hose, when installing the sleeve, it must be given a slight slope towards the street.

1. Even though the air conditioner will only be used during the hot summer months, the window insert for the floor standing air conditioner will remain in place as the weather gets colder. To prevent the cold from penetrating into the hole in winter, you need to make a thick, insulated plug for it in advance.
2. Some models of floor-standing air conditioners, as standard, have a ready-made insert for connecting the air hose to the window. It is made in the form of a telescopic plastic strip with an oval hole, and is equipped with a sleeve for connecting a hose.
3. If used, it is also installed in the lower part of the window, and its length is adjusted by extending the internal telescopic bar.

All mobile floor-standing air conditioners are equipped with a removable collection container, so during long-term operation of the device, it must be periodically removed and the accumulated water poured out of it.

Conclusion

In conclusion, I would like to remind you that for normal operation of a window monoblock, its rear part must be freely blown from all sides by cool ambient air from the street. For this reason, it is not allowed to install a window air conditioner in deep openings or blind wall niches.

It is also prohibited to cover its outer part with decorative protective grilles or other similar devices that may interfere with the free circulation of air. To get visual information on installing window air conditioners, I recommend watching the video in this article, and if after that you have questions, I can always answer them in the comment form.

When the summer heat sets in, any, even budget, air conditioner option becomes the most desirable purchase for the home. A simple window air conditioner will provide a favorable climate in the room of an apartment or private house. But installing a window air conditioner has its own nuances, which we will consider in this article.

When installing the product in a window unit, fastening is carried out directly in the structure of the latter. In this case, it is necessary to take into account that the air intake grilles do not overlap - otherwise Electrical engine The air conditioner will quickly overheat due to the lack of normal air flow.

Independently installing household appliances of this class is a very labor-intensive job; it requires certain technical knowledge, skills, and careful and precise actions. The slightest distortion of the plane of the window and the product is fraught with negative consequences, and any negligence can lead to damage to expensive equipment. If you decide to install the air conditioner yourself, you need to familiarize yourself with the following important points.

1. For any design of such a product, a gasket is required separate line electrical wiring , mandatory installation of an RCD (residual current device) in the apartment panel. The window-type air conditioner must be connected to a separate outlet; the use of carriers is strictly prohibited.
2. Between the air conditioner housing and window block There should be no gaps to avoid drafts and other negative impacts for efficient operation of the product.

Only clear execution of sequential actions during equipment installation can ensure normal operation and stable work products.

How to position the air conditioner correctly

Before installing a window type air conditioner with your own hands, you need to study the following rules for the location of the device.

Don’t forget about the security of your apartment - insert a wedge into the window so that it cannot be opened from the outside, otherwise a burglar will be able to enter the room by opening the window opening and pushing the product out of its designated place.

Having completed everything thoroughly listed rules, you ensure long and trouble-free operation of your air conditioner.

Minimum set of tools

Installation of a window air conditioner begins with preparing the necessary tools:

• impact type drill or hammer drill;
• set of drills;
• metal file for cutting metal-plastic of the required size;
• set of chisels;
• glass cutter;
• ordinary level;
• grinder or special attachment for a drill with a cutting wheel;
• internal and flat corners for furniture;
• silicone based sealant;
• paint and brush.

Before installing a window air conditioner, you need to draw up a work plan, take careful measurements and order special frame made of similar material with a hole in the middle for the product. The last point is especially important for metal-plastic windows, because such an installation is significantly different from installing an air conditioner in a wooden frame. The algorithm is almost identical, but there is much more work with metal-plastic due to its specific properties and standard sizes glass block In simple wooden frame All you have to do is remove part of the glass, insert a bulkhead and that's it. Installing a window air conditioner in a plastic window is more difficult: it requires special calculations, otherwise it simply will not withstand the load.

Installation algorithm

Installation of a window air conditioner in a wooden or plastic window is carried out according to a practice-proven technique provided by experienced craftsmen. The preparatory stage is considered the most difficult and time-consuming: if you have not ordered a separate frame with a prepared compartment to accommodate the device, you will have to cut out the excess glass and insert a jumper made of a similar material. In the case of metal-plastic, you cannot do without a specialist, because an incorrectly calculated partition during operation can bend and negate all your efforts.

Modern models of air conditioners are made in such a way that it is not so difficult to fix them in any window unit or frame design, regardless of whether they open. This is possible thanks to a special mechanism that is removed and attached to the bracket.

Before installing the product at the place of future work, it is necessary to unblock the compressor and fan of the device from the transport gaskets.

During installation, check tilt angle towards the street to effectively remove condensation. There should not be even small gaps during installation - they are removed using sealant. When all operations are completed, you need to touch up the damaged coating.

The air conditioner is designed to pump cooled air into the interior, with constant formation of condensate due to the temperature difference, which is removed through a special hole to which it must be connected liquid drain hose out. The hose must be checked for air pockets that impede the removal of moisture and kinks; the lower end of the tube or outlet structure should not touch the surface of the earth or the surface of the water in the container into which the resulting liquid flows, if you live on the ground floor.

Each air conditioner must be grounded after installation - the terminals must be secured firmly to prevent unexpected breakdowns.

After completing all work, it is necessary to visually check the correctness of execution, only after this can you do trial run to check the functionality of the air conditioner, make sure its power. If you invited specialists, then you need to draw up an acceptance certificate to certify correct execution all works.

Advantages and disadvantages

Household appliances such as a window air conditioner do not require separate installation of freon lines between the exterior and interior, which greatly simplifies installation and increases reliability.

Advantages:

• easy installation and maintenance;
• high efficiency with small dimensions;
• models with built-in cleaning filters provide a supply of already clean air, without impurities.

Flaws:

• increased noise up to 59 dB;
• violation of the tightness of the window frame;
• separate costs for making an opening for the device.

It is worth mentioning separately about noise: if you look at the table of various noises, then the operation of a window air conditioner at minimum speed produces the least noise impact, and at maximum it makes no more noise than an ordinary conversation.

Window air conditioners are one of the earliest representatives of a wide family of climate control equipment. First appearing in the 30s. 20th century in the United States, they are still in great demand. In many ways, the great popularity of these household appliances due to their high reliability and ease of installation.

Window units are one of the earliest representatives of a wide family of climate control equipment. First appearing in the 30s. 20th century in the United States, they are still in great demand. The great popularity of these household appliances is largely due to their high reliability and ease of installation. Unlike complex split systems, even an ordinary qualified mechanic can install window air conditioners.
Although the matter is not very complicated, it requires certain knowledge and accuracy. Therefore, before starting work, you should carefully study the manufacturer’s instructions. The design of the window air conditioner is a single monoblock, into which all the mechanisms of the device are built. The air conditioner is installed directly in the window or in the wall adjacent to it, if its thickness allows (it must be at least 15 cm). To do this, first of all, a rectangular opening is created, 10-15 mm larger than the dimensions of the air conditioner.

The location for installing the window air conditioner should be chosen so that it is not exposed to dirt or precipitation. It is preferable to place the device in the shade, without direct sunlight. It is important to consider that the external openings of the air conditioner (blinds), located on the sides of the housing and on top, must be open. Under no circumstances should the air conditioner be embedded in the wall or covered with something, otherwise air access will be greatly hampered and this can lead to damage to the device.

A frame with a slope made of a steel angle profile is inserted into the prepared opening. The frame is firmly fixed in the opening with a slight slope so that the lower edge of the outer part of the air conditioner is slightly lower than the edge of the inner part. This position ensures faster drainage of condensate.

The remaining gaps between the walls of the opening and the air conditioner body are filled with polyurethane foam. It is worth noting that some modern models window air conditioners are equipped with a removable outer casing. In this case, there is no need to make a special frame - the window air conditioner is installed in its own removable casing, built into the prepared opening.

Features of connecting the device to electrical network depend on its power. Low-power household air conditioners can easily be connected through a regular electrical plug. However, for more powerful systems You will need to create a separate wiring and connect through an individual machine. In this case, you should call a qualified electrician who can carry out this work in accordance with safety regulations.

Features of installing a window air conditioner

The window air conditioner is a monoblock, so its installation is simpler than in the case of a split system: there is no need to lay freon routes, check the tightness of pipelines, etc. In addition, when installing the window, no work at height is required. However, for normal operation of the air conditioner, you must strictly follow the sequence of installation steps.

Please note the following:
For an air conditioner of even low power, it is recommended to lay separate electrical wiring and install a separate “automatic machine” in the distribution panel.
When choosing a window air conditioner, you should make sure that its width is less than the width of the window
The air conditioner must be installed without distortion, otherwise condensation will drain onto the floor.
There should be no gaps left between the air conditioner body and the planes of the opening cut for its installation.
installation of a window air conditioner will be very labor-intensive if stained-glass windows or double-glazed windows in PVC or aluminum frames are installed in the house or office

Installation rules:
The air conditioner must be firmly fixed, otherwise the noise level during its operation will increase (already quite high).
The air conditioner should not be exposed to direct sunlight.
The outer side of the air conditioner should protrude into the street by at least 25-30 cm
The distance from the external panel of the air conditioner to the nearest obstacle (wall) must be at least 50 cm, otherwise air circulation will be difficult and the cooling performance of the air conditioner will decrease.
All side vents of the air conditioner must be open and there must be no obstructions (side walls) on either side of the air conditioner.
Install the air conditioner with a slight downward slope outward (this is necessary for free condensate drainage)
The outer edge of the air conditioner should be 1-2 cm lower than the inner one.
The bottom of the air conditioner should be located at a height of 75-150 cm from the floor.

1. Selecting a location for installing the air conditioner
The location for installing a window air conditioner must be selected taking into account the shape of the room and the location of the furniture, as well as other factors. When choosing a location, consider the following:
Carefully inspect the window frame and wall to make sure they are strong enough to mount the air conditioner. Different materials and finishes on the interior and exterior of the wall and frame may require different mounting methods for the air conditioner. To fasten a window air conditioner, bolts (including anchors) and mounting brackets and corners that have sufficient strength are used.

If the wall is not strong enough or the edges of the holes are crumbling, it is necessary to strengthen the wall, otherwise the air conditioner may fall, condensation leaks, or increased noise and vibration during its operation.
if the wall is strong enough, tighten the bolts and attach the air conditioner
if the edges of the window opening are not strong enough (they may crumble), reinforce the edge of the opening with a metal corner
the wall is not strong enough, it is necessary to expand the metal support to reduce the load on the wall
if the edges of the window opening are not strong enough (they may crumble), reinforce the lower edge of the opening with a metal corner

Ensure condensation generated during operation of the window air conditioner is removed. For unhindered water flow, the back of the air conditioner should be slightly (0.5-1 cm) tilted down. The left and right sides of the air conditioner must be strictly at the same level. Otherwise, water may drip from the air conditioner body.

The air exiting from the rear side of the air conditioner (to the street) has high temperature. It should not come into contact with animals, plants or people.

For maintenance, you must leave at least 10 cm of free space to the right or left of the air conditioner and above it. In order for cooled air to circulate freely throughout the room, cooling it evenly, the air conditioner must be located in the center.
There should be no obstructions around the air conditioner to allow air in and out, otherwise its performance will be reduced. If the air conditioner is exposed to direct sunlight, it must be protected with a canopy from above and from the sides. The canopy should not impede air circulation.

2. Installation kit for window air conditioner

There are a number of installation kits on the market for installing a window air conditioner. Here is an example of one of them.

3. Sequence of installation of a window air conditioner

The window air conditioner is installed as follows:
The most difficult stage is preparing the opening for the air conditioner. IN window opening Almost any type, you can always find the most optimal place to install the air conditioner. It is best to carry out installation in a place where at least one of the sides (length or height) would fit in the opening with minimal gaps. In this case, installers are required to:
take out the glass
put a “jumper”
cut glass to size.

If the air conditioner is wall mounted: Drill holes in the wall. Mark on the wall or window where the air conditioner is mounted and its overall dimensions. Draw lines corresponding to the dimensions of the air conditioner and drill holes with a drill at a distance of approximately 5 cm (inside the air conditioner contour) from these lines.

Attention!
a) if the air conditioner is installed in a wall, then the thickness of the wall should be no more than 250 mm (this is the size of one brick). If the thickness is greater, it will block the access of air to the intake grilles for cooling the condenser and the air conditioner will fail.
b) if the air conditioner is installed in a window opening, the distance between the frames of which is more than 250 mm, then if there is a window in the outer frame of the window, the air conditioner can be operated.

Install the bracket and air conditioner housing.
Modern models of window air conditioners allow installation even if the windows do not open and there is no access to the outside, due to the fact that the entire air conditioner mechanism is removed from the housing, which is attached to a bracket or to the wall. To ensure unimpeded water flow, the back of the housing should be slightly tilted downwards. The left and right sides of the body must be strictly at the same level. The connection points must be sealed to prevent precipitation and wind from entering the room. If the walls are not strong, the air conditioner bracket may rest on the floor.

Install the air conditioner into the assembled housing. If shock-absorbing pads have been used to protect the compressor and fan during transportation, they must be removed before installing the air conditioner, otherwise they will interfere with the operation of the air conditioner, causing noise and vibration. When you insert the air conditioner into the housing, make sure that the back of the air conditioner is slightly inclined downwards, ensuring drainage. For models 7, 9, 12, the slope should be 6.5 mm, for models 18, 24 - the slope should be 10 mm. All cracks and gaps between the housing, the wall and the air conditioner must be sealed to prevent drafts. The air conditioner kit includes a standard foam seal. Large gaps sealed with foam rubber, small - silicone sealant. Then you need to paint over the damaged areas of the frame.

Connecting the drainage hose. When a window air conditioner operates, the air in the room is cooled and moisture condenses from it. If you do not connect the drainage hose, water will drip out of the drain hole air conditioning, which is usually undesirable. If the drainage tube becomes kinked, make sure there is no blockage in the drainage tube. airlock, interfering with the flow of water. The tube should not touch the ground and should not touch the water level in the container.

Power supply window air conditioner.
The window air conditioner supply voltage should be within 90%-110% of the rated voltage.
To power the air conditioner, it is necessary to draw a separate line with a circuit breaker, independent of the main fuse. The capacitive current of the switch should be 1.5 times greater than the maximum current consumed by the air conditioner.

Electrical equipment (power cord, socket, switch, grounding wire, etc.) must comply with national safety standards and recommendations contained in the air conditioner documentation (user manual, installation instructions and data plate on the air conditioner body).

The window air conditioner must be grounded. The ground wire and terminals must be securely fastened. Improper power supply to the air conditioner can cause it to fail. Therefore, be very careful when electrically connecting and grounding your window air conditioner.

Checking the operation and acceptance tests of the window air conditioner After completing the installation, carefully check again whether all the work has been completed correctly. Only then turn on the air conditioner to check its operation. All problems with the air conditioner must be corrected in a timely manner. If you cannot solve the problem, contact the head of the installation department of your company. After the acceptance test of the air conditioner, explain to the user how to use and maintain the air conditioner. Complete the installation certificate, which must be signed by the installer and the user (owner) of the air conditioner.

Window air conditioner diagram, operating principle

A window air conditioner is a monoblock that is mounted in the window opening of a room. This type of air conditioner is especially convenient when you need to quickly and efficiently install the equipment yourself.

In hot weather, when the waiting period for installing an air conditioner drags on like an eternity, the window will the best solution. Currently, many manufacturers offer a whole range of such air conditioners, which differ in power and range of functions.

So LG offers inexpensive household options with a cooling capacity of 3 kW. Although this model is noisy, like all window air conditioners, it does an excellent job of cooling a room of 20 meters.

Our website presents window frames of any capacity, so it will not be difficult for you to choose exactly what you need.

If you decide to purchase a window air conditioner:

1. After the air conditioner is installed, make sure that its outer panel is not blocked by curtains, curtains or blinds. If this is not observed, the window window will create a wonderful microclimate between the curtains and the window, and not in the room for which it was purchased.

2. When installing, make sure that there are no gaps between the air conditioner unit and the window frame. Otherwise, insufficient airtightness will result in you cooling the street and not your room.

3. A plastic window is not a window maker’s friend, since installation of a PVC window is a difficult task and there is no certainty that it will be completed.

4. The window is noisy, take this into account!

Monoblock air conditioner, which is mounted in a window opening or thin wall.

Basic modes and options

Provides cooling, dehumidification, rough cleaning air. Some models heat and mix air from the street (or extract it).

Advantages

Among the advantages are low price and ease of installation. In addition, window air conditioners have another advantage - most of them are capable of partially extracting the air passed through the device. In this case, the flow of fresh air into the room occurs through leaks in doors and windows.

Flaws

The disadvantages include high level noise and lack of freedom to choose the installation location. Temperature adjustment, much less setting it, is not possible (only the air conditioner power is adjusted). When installing a window air conditioner, you need to remember that it is better not to sit at a distance of one and a half to two meters from it in the direction of the release of cold (heated) air.

In Russia, "windows" are used mainly for air conditioning street shopping pavilions and government low-budget institutions.

Installing a window air conditioner does not require special skills or tools, and therefore even a novice carpenter can install it. The main thing is to avoid distortion and not leave gaps between the air conditioner housing and the window frame.

When purchasing a window air conditioner, you need to remember the following:

It should not be blocked by thick curtains or blinds. In this case, the air conditioner will create comfort not in the room, but in the space between the window and curtains.

When choosing a window air conditioner, you need to make sure that its width is less than the width of the window.
When installing in double-glazed windows, the hole for the air conditioner should be made in advance when making the windows. If your home or office already has stained glass or double glazing in PVC or aluminum frames, installing a window air conditioner can be golden. In addition, in this case the air conditioner will not be able to work as an extractor.
If the inter-frame space is significant (for example, a shop window), installing a window air conditioner can be extremely difficult. Also in the case of glazing of a large area, or with a significant thickness of glass.

Processed

Window air conditioner—monoblock, so its installation is simpler than in the case of a split system: there is no need to lay freon routes, check the tightness of pipelines, etc. In addition, when installing the window, no work at height is required. However, for normal operation of the air conditioner, you must strictly follow the sequence of installation steps.

Please note the following:

• For an air conditioner of even low power, it is recommended to lay separate electrical wiring and install a separate “automatic machine” in the distribution panel.
• When choosing a window air conditioner, you should make sure that its width is less than the width of the window
• The air conditioner must be installed without distortion, otherwise condensation will drain onto the floor.
• There should be no gaps left between the air conditioner body and the planes of the opening cut for its installation.
• installation of a window air conditioner will be very labor-intensive if stained-glass windows or double-glazed windows in PVC or aluminum frames are installed in the house or office

Installation rules:

1. The air conditioner must be firmly fixed, otherwise the noise level during its operation will increase (already quite high).
2. The air conditioner should not be exposed to direct sunlight.
3. The outer side of the air conditioner should protrude into the street by at least 25-30 cm
4. The distance from the external panel of the air conditioner to the nearest obstacle (wall) must be at least 50 cm, otherwise air circulation will be difficult and the cooling performance of the air conditioner will decrease.
5. All side vents of the air conditioner must be open and there must be no obstructions (side walls) on either side of the air conditioner.
6. Install the air conditioner with a slight downward slope outward (this is necessary for free condensate drainage)
7. The outer edge of the air conditioner should be 1-2 cm lower than the inner one.
8. The bottom of the air conditioner should be located at a height of 75-150 cm from the floor.

1. Selecting a location for installing the air conditioner

The location for installing a window air conditioner must be selected taking into account the shape of the room and the location of the furniture, as well as other factors. When choosing a location, consider the following:

1. Carefully inspect the window frame and wall to make sure they are strong enough to mount the air conditioner. Different materials and finishes on the interior and exterior of the wall and frame may require different mounting methods for the air conditioner. To fasten a window air conditioner, bolts (including anchors) and mounting brackets and corners that have sufficient strength are used.
   If the wall is not strong enough or the edges of the holes are crumbling, it is necessary to strengthen the wall, otherwise the air conditioner may fall, condensation leaks, or increased noise and vibration during its operation.
   • if the wall is strong enough, tighten the bolts and attach the air conditioner
   • if the edges of the window opening are not strong enough (they may crumble), reinforce the edge of the opening with a metal corner
   • the wall is not strong enough, it is necessary to expand the metal support to reduce the load on the wall
   • if the edges of the window opening are not strong enough (they may crumble), reinforce the lower edge of the opening with a metal corner
2. Ensure condensation generated during operation of the window air conditioner is removed. For unhindered water flow, the back of the air conditioner should be slightly (0.5-1 cm) tilted down. The left and right sides of the air conditioner must be strictly at the same level. Otherwise, water may drip from the air conditioner body.
3. The air coming out from the rear of the air conditioner (to the street) has a high temperature. It should not come into contact with animals, plants or people.
4. For maintenance, you must leave at least 10 cm of free space to the right or left of the air conditioner and above it. In order for cooled air to circulate freely throughout the room, cooling it evenly, the air conditioner must be located in the center.
5. There should be no obstructions around the air conditioner to allow air in and out, otherwise its performance will be reduced. If the air conditioner is exposed to direct sunlight, it must be protected with a canopy from above and from the sides. The canopy should not impede air circulation.

2. Installation kit for window air conditioner

There are a number of installation kits on the market for installing a window air conditioner. Here is an example of one of them.

3. Sequence of installation of a window air conditioner

The window air conditioner is installed as follows:

1. The most difficult stage is preparing the opening for the air conditioner. In a window opening of almost any type, you can always find the most optimal place to install an air conditioner. It is best to carry out installation in a place where at least one of the sides (length or height) would fit in the opening with minimal gaps. In this case, installers are required to:
   • take out the glass
   • put a “jumper”
   • cut glass to size.

If the air conditioner is wall mounted: Drill holes in the wall. Mark on the wall or window where the air conditioner is mounted and its overall dimensions. Draw lines corresponding to the dimensions of the air conditioner and drill holes with a drill at a distance of approximately 5 cm (inside the air conditioner contour) from these lines.

Attention!

a) if the air conditioner is installed in a wall, then the thickness of the wall should be no more than 250 mm (this is the size of one brick). If the thickness is greater, it will block the access of air to the intake grilles for cooling the condenser and the air conditioner will fail.
b) if the air conditioner is installed in a window opening, the distance between the frames of which is more than 250 mm, then if there is a window in the outer frame of the window, the air conditioner can be operated.

Install the bracket and air conditioner housing.

1. Modern models of window air conditioners allow installation even if the windows do not open and there is no access to the outside, due to the fact that the entire air conditioner mechanism is removed from the housing, which is attached to a bracket or to the wall. To ensure unimpeded water flow, the back of the housing should be slightly tilted downwards. The left and right sides of the body must be strictly at the same level. The connection points must be sealed to prevent precipitation and wind from entering the room. If the walls are not strong, the air conditioner bracket may rest on the floor.
2. Install the air conditioner into the assembled housing. If shock-absorbing pads have been used to protect the compressor and fan during transportation, they must be removed before installing the air conditioner, otherwise they will interfere with the operation of the air conditioner, causing noise and vibration. When you insert the air conditioner into the housing, make sure that the back of the air conditioner is slightly inclined downwards, ensuring drainage. For models 7, 9, 12, the slope should be 6.5 mm, for models 18, 24 - the slope should be 10 mm. All cracks and gaps between the housing, the wall and the air conditioner must be sealed to prevent drafts. The air conditioner kit includes a standard foam seal. Large cracks are sealed with foam rubber, small ones with silicone sealant. Then you need to paint over the damaged areas of the frame.
3. Connecting the drainage hose. When a window air conditioner operates, the air in the room is cooled and moisture condenses from it. If you do not connect the drain hose, water will drip out of the air conditioner drain hole, which is usually undesirable. If the drain tube is bent, make sure there is no air pocket in it that is preventing water flow. The tube should not touch the ground and should not touch the water level in the container.
4. Electrical power supply for window air conditioner.
   1. The supply voltage of the window air conditioner should be within 90%-110% of the rated voltage.
   2. To power the air conditioner, it is necessary to draw a separate line with a circuit breaker, independent of the main fuse. The capacitive current of the switch should be 1.5 times greater than the maximum current consumed by the air conditioner.
   3. Electrical equipment (power cord, socket, switch, grounding wire, etc.) must comply with national safety standards and recommendations contained in the air conditioner documentation (user manual, installation instructions and data plate on the air conditioner body).
   4. The window air conditioner must be grounded. The ground wire and terminals must be securely fastened. Improper power supply to the air conditioner can cause it to fail. Therefore, be very careful when electrically connecting and grounding your window air conditioner.
5. Checking the operation and acceptance tests of the window air conditioner After completing the installation, carefully check again whether all the work has been completed correctly. Only then turn on the air conditioner to check its operation. All problems with the air conditioner must be corrected in a timely manner. If you cannot solve the problem, contact the head of the installation department of your company. After the acceptance test of the air conditioner, explain to the user how to use and maintain the air conditioner. Complete the installation certificate, which must be signed by the installer and the user (owner) of the air conditioner.
