Installing an air conditioner in the corridor: choosing the best place and the nuances of installing an air conditioner

Site Selection Criteria

This is not the way to place the air conditioner.

The location where your indoor unit will be installed should be the most suitable. Where can it be installed? For example, in the bedroom.

As for this vault of peace, you will have to puzzle over which wall to install it on. You can, of course, hang over your head - at the head. Or on the opposite wall.Where is better? In both cases, cold streams will not bring you any harm only if the air conditioner is not located above the bed itself. If there is no other suitable place, then make sure that the air flow does not fall on you.

With the right choice of location, refreshment in hot weather will be guaranteed. And yet you should not relax - there is still something to think about.

In such a bedroom it is not easy to find a place suitable for air conditioning.

First, the furniture. If the bedroom is loaded with bulky furniture, this creates the danger of dusting this room. The fact is that when the unit is close, say, to a closet, the ubiquitous dust that is on it, when the air conditioner is running, can end up in your lungs and, most unpleasantly, in your bed, which will invariably create a feeling of discomfort instead of the expected pleasure. Please note that the distance to the furniture must be at least 70 cm.

Air conditioning fit into the interior

Secondly, the interior. The indoor unit of the air conditioner should fit beautifully into the overall interior. Therefore, it is not necessary to mount it opposite the bedroom door or high up to the ceiling. It's not beautiful. The distance from the ceiling should be 10-15 cm.

One air conditioner for two rooms

Now let's talk about the second room. After all, she, along with the bedroom, also claims to be the coolest room in the apartment. Here, the movement is more active compared to the bedroom. It is clear that you can’t turn the unit down anywhere in the room. As noted above, it should fit beautifully into the overall interior and not blow over everyone who is there with their cold streams.

Don't forget about communication. Most likely, they will be external and hidden in the cable channel.Remember, the longer these communications, the more expensive it will cost you to install an air conditioner.

Yes, and imagine how the entire wall of your room is crossed out by a white stripe of the cable channel. Will it be beautiful?

All communications in the gate

Height difference between blocks

In addition to the length between the modules of the split system, a certain height difference must also be maintained. It is always indicated in the instructions and for household models it is usually no more than 5 m, less often - 10. Large values ​​are typical for semi-industrial and industrial models - up to 20-30 m.

The largest height differences are in industrial climate systems of the VRV type. The height difference between indoor and outdoor units can be up to 90m

If the length of the freon route can be slightly increased, then experimenting with the height is prohibited. For this reason, the outdoor unit is most often installed 2-3 m below the wall unit.

The owners of city apartments have little choice - next to a balcony or window. Owners of one-story cottages sometimes install an external module directly on the ground, on special supports. We talked in detail about choosing the optimal place for installing the air conditioner in our article.

Optimum indoor air exchange is a guarantee of human safety

It has been noticed that if a person’s work is not related to being outdoors, then he spends from 16 to 24 hours a day in an apartment or office. This is where ventilation plays an important role. According to the norms, the air in the room should be updated every 1-2 hours. If this rule is not observed, excessive carbon dioxide and humidity accumulate in the rooms. This leads to a deterioration in human well-being, the appearance of mold and fungus on the walls.Microbes and allergens accumulate in a poorly ventilated room. Stuffiness, "weeping" windows, the formation of mold and fungus, as well as the deformation of wooden furniture - all these are clear indicators that air exchange is disturbed in the apartment.

Undoubtedly, the ventilation system in our homes is installed in order to solve the problem of insufficient air exchange, coupled with periodic ventilation. Ideally, air should enter the apartment through the windows, circulate freely around the apartment through the gaps between the door and the floor, and then be freely removed from the room through the ventilation ducts, which are usually located in the bathroom, toilet and kitchen.

To create a healthy atmosphere in the apartment, it is recommended to perform the following steps:

Use a simple test with a thin paper strip to verify that the ventilation is working properly. If the test showed that the air from the room is not removed or is difficult to remove through ventilation, then the channel must be cleaned

In multi-apartment residential buildings, the maintenance of ventilation ducts is the responsibility of the management company or HOA.
Notice the windows. Through the old wooden frames, street air enters the room through the cracks.

However, if plastic windows with a seal between the frames are installed in the apartment, then street air no longer penetrates into the apartment when the windows are closed. In this case, the installation of supply valves is recommended.
Install an air conditioner in the room to cool or heat the air in the room, and to remove dust.

Such activities will help create a healthy microclimate in the apartment, which will improve the well-being of its inhabitants.But the choice of the installation location of the indoor unit in the room must be taken as carefully as possible so as not to harm human health and not shorten the life of the device.

First way

Installation work begins with the laying of cables connecting the evaporator to the outside of the system.

For this:

• A wire is laid to connect the air conditioner modules;
• A separate line is drawn if the system has a large capacity and is equipped with a cable and an automatic machine that protects the system from possible overloads;
• The air conditioner is directly connected to the mains. For this purpose, an ordinary standard socket is used if the power of the device is in the middle range.

The implementation of the last method of connecting an air conditioner is possible in several cases:

• Small power equipment;
• Installing a mobile or window class system;
• Temporary installation of the device;
• The electrical network in the apartment is designed for a sufficiently large power;
• Use the selected line for the air conditioner only.

The presence of individual protection for the air conditioner is mandatory, since during operation the device operates in different modes. Depending on the selected mode, the power of the equipment can vary from maximum to minimum and vice versa. If the set parameters are exceeded, the machine will prevent the failure of the air conditioner.

The delivery of any climatic equipment always includes instructions for installation, connection and use.

The documentation reflects:

• Scheme of the system;
• The general connection diagram, which should guide the user when performing installation work;
• The electrical diagram of the air conditioner, reflecting the procedure for performing work when connecting the indoor and outdoor units.

For the convenience of the user, the information is duplicated. It is located on the inside of the cover of the indoor module and on the body of the unit mounted outside the house. With independent installation of the air conditioner, this greatly simplifies the installation work.

The evaporator is connected to the terminals located in a special box under the front panel. Installation of a split system is carried out inside the room.

The wires of the indoor unit of the air conditioner are connected to the terminals of the outdoor unit. During installation, they are guided by the numbering presented in the circuit diagram. The remaining cores are carefully insulated using a special tape. Before putting the climatic equipment into operation, the quality of the insulation is additionally checked in order to exclude a short circuit during the subsequent operation of the equipment.

In some cases, the installation of climatic equipment in a country house or apartment should be abandoned.

These reasons include:

• Old wiring, which is based on an aluminum cable;
• Insufficient cross-sectional dimensions of the wire: the wiring will not withstand the load;
• Non-compliance of wiring with regulatory requirements;
• Poor grounding, lack of protection against power surges.

Any climate control equipment is sensitive to power surges. To prevent premature failure of the air conditioner, before starting the connection, make sure that the power supply is working.If it does not comply with regulatory requirements, a complete replacement of the wiring may be required.

Where to install the indoor unit of the air conditioner

The installation location of the indoor unit of the split system must be chosen in accordance with all the rules. For example, if it is supposed to be installed in the bedroom, then which wall to choose for this - opposite the bed or directly above the bed? In principle, both options are allowed, since the cold air currents from the air conditioner will not disturb, but only if they are not directed directly at the bed.

Please note: if the indoor unit of the air conditioner is located above the bed (on the wall at the head), then you should prepare for the fact that cold air flows will still flow directly to the plane of the bed. Another nuance that should be taken into account is the amount of furniture in the bedroom or any other room.

If there is a lot of it and it is quite bulky, then get ready for excessive dusting in the room - when the air conditioner is running, the accumulated dust on the surface of the furniture will rise into the air and settle not only on the bed, tables, cabinets, but also in the lungs of people. To prevent this from happening, follow a simple rule - the indoor unit of the air conditioner must be located at a distance of at least 70 cm from furniture

Another nuance that should be taken into account is the amount of furniture in the bedroom or any other room. If there is a lot of it and it is quite bulky, then get ready for excessive dusting in the room - when the air conditioner is running, the accumulated dust on the surface of the furniture will rise into the air and settle not only on the bed, tables, cabinets, but also in the lungs of people

To prevent this from happening, follow a simple rule - the indoor unit of the air conditioner should be located at a distance of at least 70 cm from furniture.

Do not forget that the indoor unit of the air conditioner should fit into the overall interior, become one with it and not create disharmony. Therefore, experts do not recommend installing the air conditioner opposite the front door to the room and too high on the wall, close to the ceiling. Remember that the indoor unit of the split system must be installed 15-20 cm below the ceiling level.

Keep in mind that you will need to make strobes in the wall and lay all the wires going from the indoor unit to the outdoor unit there. Agree, communications hanging on the walls will not add style to the interior of the room.

The location of the air conditioner in the bedroom

When buying an air conditioner, it is also necessary to properly position it in the bedroom in order to create exactly comfortable conditions and not harm your health.

There are several options for placing the air conditioner:

1. Opposite the bed - not the best option. The flow of cold air coming out of the air conditioner tends to the opposite wall and falls directly on the heads of sleeping people. There is a high probability of catching a cold, catching a cold in the ear, neck and other parts of the body.
2. Above the door is a better placement option. In this case, the air conditioner becomes invisible, air flows are evenly distributed over all areas of the room and directed towards the window. In automatic mode, the air conditioner starts to cool the room faster, since the air exits through the door, which means that the temperature rises most quickly in this place.The downside of this arrangement is too much distance from the window. Cable wiring for such a length will cost much more.
3. Opposite the room door is an unfortunate location. The air conditioner, although small in itself, should not be conspicuous during installation. Its location opposite the front door makes it always visible when entering the room, which creates a certain discomfort for the owners of the apartment.
4. Next to the window - this arrangement of the air conditioner allows you to save on its installation by using which way to the external unit. However, the proximity to the window creates additional restrictions on the design of the room with curtains, forcing you to choose light tulle or curtains for design, which, moreover, will have to be constantly pushed aside when the air conditioner is running.

Each of the options for placing the air conditioner in the bedroom has its own advantages and disadvantages. Everyone chooses the best options for himself - someone likes comfort, and someone prefers aesthetics. In any case, the air conditioner in the bedroom should bring only positive emotions to its owners.

Do-it-yourself air conditioner connection sequence

Installation of the air conditioner is carried out in several stages. First, the wiring is laid.
Next, the external unit of the system is installed.
The technology requires that it be placed at a height of at least 180-200 cm from ground level. This requirement is relevant for owners of private houses and residents of apartments located on the ground floor.

Holes are drilled in the outer wall for laying communications.
The diameter of these holes should be 500-600 mm. Brackets are installed, due to which the unit will be fixed.A special waterproofing cup is inserted into the prepared hole and direct connecting communications are laid.

The next step is to install the indoor unit.
The maximum allowable distance between these two elements is 20 m. The optimal distance is 7-12 m. Specific recommendations are given in the instructions for the equipment, be sure to study it before starting installation. Install the brackets and fix the indoor unit of the air conditioning system.

In the end, it remains only to lay the wires, due to which the functioning of the system will be ensured. Mount the box. It, as already noted, can be internal or external. Connect electrical wires and pipes for freon. Evacuate the system. For this, special equipment is used. The actual procedure lasts an average of 45-60 minutes.

System start

Having finished all the work on switching, proceed to the launch. The system must be prepared by removing all air, nitrogen and moisture from it. They get into the pipes during their installation. If the system is not cleaned of foreign gases, then the load on the compressor will increase, and its useful life will decrease.

Moisture also has a negative effect on the performance of the system. The composition of freon pumped into the air conditioner contains oils. It is designed to lubricate the internal elements of the system. Since the oil has a hygroscopic structure, it will lose its effectiveness when mixed with water. In turn, this will lead to premature wear of the system elements.

It becomes clear that this operation is necessary. The system will start, of course, but for a short time.Removal of air and other foreign matter is carried out in two ways:

• the inlet of freon into the system;
• vacuum pump.

The first method can be carried out due to a small additional supply of freon pumped into the indoor unit. It is only suitable for trails no longer than 6 meters. That is why a vacuum pump is required for longer communications. If you blow a long system out of the indoor unit, then there will be no freon left for its operation.

Control valve at the bottom of the block

freon inlet

Before starting the operation on the outdoor unit, the plugs and covers on the valves are unscrewed. Next, the valve of the indoor unit on the larger diameter pipe opens for 1 second. This is done based on the design of the valve. Typically a hex wrench is used.

Having supplied freon to the system and creating excess pressure, it is necessary to relieve it. This is done with the help of a spool on the same pipe, by pinching with a finger. At the same time, you need to leave a small amount of freon in the system so that fresh air does not enter there. This procedure is repeated a couple of times.

After its completion, a plug is screwed onto the spool, and the valves on both pipelines are fully opened. To check the quality of the joints, you can smear them with soap suds.

Vacuum pump

This procedure requires not only a vacuum pump, but also a high pressure hose. You will also need two pressure gauges - for low pressure and high pressure.

The hose is connected to the spool of the thick pipeline. In this case, both valves must be closed.After switching the vacuum pump to the system, it is turned on and left to work for 15-30 minutes. This time is quite enough to pump out air and other impurities from the pipelines.

Vacuum pump with pressure gauge

After turning off the pump, it must be left connected to the pipeline with the valve closed. In this position, the system should stand for about 30 minutes. During this period of time, pressure indicators are monitored. If all connections are tight, the instrument arrows should remain in place.

If the readings begin to change - somewhere poor-quality sealing. As a rule, these are the places where pipes are connected to the blocks. Their additional broach eliminates the problem. If it does not help, then the leak is detected with soap suds.

System pressure control

If the complete tightness of the system is confirmed, then leaving the pump connected, the valve on the thick pipeline opens. After the characteristic sounds fading, indicating that the pipes are filled with freon, the pump hose is unscrewed. It is better to do this with gloves so as not to get frostbite from freon residues. Now you can open the valve on the thin pipeline. Everything is ready - the system can be turned on.

Conclusion

In conclusion, I would like to note that the installation and launch of both air conditioners and split systems is a rather complicated undertaking. It is necessary to have the skills of construction and installation works, to understand the technical documentation and materials. That is why, in most cases, specialists are involved in such work.

Moreover, some large split systems are installed only by representatives of the manufacturer's plant.Otherwise, the service warranty will be void.

We also note that the launch of air conditioning systems using vacuum pumps is carried out in Russia and neighboring countries. In world practice they are not used. For example, the same Israel where air conditioners are not turned off all year round. Why this is done is a question for foreign experts.

What is important when installing an air conditioner in an apartment

1. The distance between blocks should be minimal.
2. Installation of equipment is best done during the repair, and not after its completion.
3. Choose installers not by the cost of services, but by the quality of the work done.
4. Hang the air conditioner where it will be useful, not where it will look beautiful.
5. Avoid installing the unit above furniture or close to the ceiling.
6. It is strictly not recommended that the air flow be directed towards a person.
7. It is optimal to direct the air masses along the window.

Minimalism welcome

The distance between the indoor and outdoor units is best kept as small as possible. Then the efficiency of the air conditioner will be great. The further you lead the freon route, the more the compressor unit will have to work to distill the freon to the evaporator and back.

Installation during renovation

Remember that any, even the most accurate installation of air conditioning equipment will lead to the formation of construction debris. This does not mean at all that in the case when the repair has already been completed, it will certainly be spoiled, but still minor nuances cannot be avoided.

Installation during renovation

The choice of installers

Here you should be guided by the principle "The miser pays twice."To minimize damage to your walls, choose installers based on reviews of real people, and not those who were recommended to you in the store. In addition, you can ask a real specialist a few questions that disturb you about the optimal place for installing both units, and setting up the equipment. Listen to the reasoned advice of the master if he recommends not installing the equipment on a weak wall or close to furniture.

The installation site should be useful, not attractive

Often people choose a place for split installation-systems, based on the general appearance of the room. There are two options here: either in the most visible place, or where it will be almost imperceptible. However, the equipment must be installed where it will have the best impact on the space and the people living in it.

Place to install air conditioner

Correct distance from air conditioner to adjacent surfaces

To prevent overheating of the indoor unit, the distance between the wall and the side of the unit should be at least 5 cm.

But, as for the distance from the front side of the air conditioner to furniture or a person, here the length of the air flow should be taken into account. Usually the coldest stream goes to a distance of 2-2.5 meters, and then dissipates. Therefore, it is recommended to keep the distance from the indoor unit to the sofa, bed, workplace at least 1.5 meters.

Air conditioning in the room

Remember that the air conditioner should cool the air space, not furniture and household members. In addition, if there is, for example, a cabinet directly under the evaporative unit, then you will encounter two problems.Firstly, dust will regularly be blown off the surface of the cabinet, which will rush into the room. And secondly, if the air flow, when leaving the air conditioner, does not dissipate in space, but hits a flat surface, then a certain vortex flow is created. This will affect the temperature sensors of the air conditioner, confusing the program. Therefore, the equipment will not work correctly, and the desired temperature in the room will not be reached.

Airflow and man

When choosing an installation point, exclude places where the directional air will blow directly at you. The air conditioner creates a sufficiently powerful air flow. If you are in close proximity to it, then this will inevitably lead to your hypothermia, and in the future to health problems.

Air flow

Why does the air conditioner have to blow along the window

It is optimal to cool exactly the hottest part of the room. Since the light from the sunny side not only penetrates the room, heating it, but also heats the wall itself from the street, this wall turns out to be the warmest. This means that it is more optimal to direct the air flow along this wall and window than to cool that part of the room that does not get sunlight.

Airflow along windows

Adding refrigerant and starting

After the vacuum in the device is created, it is possible to fill the system with refrigerant. In the case of split air conditioners, the outdoor units are filled at the factory with an appropriate amount sufficient for the piping length specified by the manufacturer. If the unit will be installed with more than 10 m, you need to determine the amount of additional refrigerant and add it before opening the valves of the outdoor unit.The volume per extra meter depends on the capacity of the system and the diameter of the pipeline. For 1⁄4 inch pipe, the amount of additional refrigerant is 20 g/m.

After filling with freon, the air conditioner is started using the remote control and the cooling mode is set, the pressure readings on the pressure gauges connected to the service valve of the air conditioner are monitored. The pressure measured by the manometer during cooling operation is the suction pressure. For the R410 A coefficient, it should be about 7.5 bar, which corresponds to a refrigerant evaporation temperature of +2 degrees.

Air conditioners for apartments with two or more rooms

There are no special differences from the previous recommendations in the selection and installation of air conditioners for two or three rooms.

Khrushchevs and their air conditioning

walk-through dvushka in Khrushchev

A standard two-room Khrushchev can get by with one split for two adjacent rooms. The indoor unit is mounted above the doorway between the rooms in the entrance hall. The air will be repelled from the opposite wall and pass into the bedroom. Usually its dimensions are from 8 to 11 m². Buying an air conditioner for such a small room is pointless. A device with a power of 3.5-4.5 kW can easily cope with the cooling and heating of two adjacent rooms.

Owners of a three-ruble apartment in Khrushchev with two adjoining rooms and one separate room can solve the problem of air conditioning without spending money on air conditioners for several rooms as follows:

• Adjacent (walk-through) rooms are designed in the same way as described in the option about a two-room apartment;
• The problem of air conditioning the kitchen and the remaining small bedroom is solved by installing a more powerful unit next to the front door in the corridor. Minus - a long freon line through the entire room or kitchen.

Rulers and their conditioning

two-room ruler

If the apartment has a layout called a "line", then there is absolutely no need to buy an air conditioner for two rooms with a limited budget, since the premises are located here in one row. It turns out that the hallway is equidistant from them. This means that you can hang an inverter in it, which will provide cold and heat to all zones. This is acceptable if the occupants are willing to endure the arctic cold in the corridor, because to lower the temperature in the rooms and the kitchen to 24°C, you will need to set 18°C ​​here.

Homeowners do not want to freeze in the hallway? Then the following recommendations regarding apartments with separate rooms will help.

Undershirts and their conditioning

three-room vest

Apartments with separate rooms are best equipped with multi-split or duct installations with air ducts between the rooms. This will save space both outside the building and inside the rooms themselves and the kitchen.

The disadvantage of such systems is the inability to set autonomous temperature parameters in different areas of the apartment. Cooling a kitchen with appliances running will require lower values ​​than cooling a bedroom or nursery.

One of the advantages of a ducted air conditioner is the possibility of mixing outside air.

ducted air conditioning system in multi-room apartments

Two separate inverter-type air conditioners can be installed in two small separate rooms.They will process the air efficiently and will not incur high electricity costs. The same can be done in a three-room apartment. But this is justified only if all the rules mentioned at the beginning of the article are observed.

If you try to place separate splits in three rooms, then this will bring little benefit to the design of the apartment itself, as well as the external appearance of the house. Much smarter to buy air conditioning for three or several rooms, that is, a multi-split system or a duct. In most cases, they have an inverter type of compressor control, which eliminates the operation of devices in the frequent start-stop mode.

Some air conditioners for three rooms can be combined with different types of indoor modules. The most powerful wall-mounted apparatus is hung in the living room, and a wall-mounted device with lower productivity is hung in the bedroom.

multi-split in a three-room apartment

Many air conditioners for three rooms do not need to be assembled on their own. Ready-made multi-splits are on sale, perfectly matched in terms of parameters relative to each other, which can be easily and quickly hung.

Professional installers will help you choose the exact options for installing the air conditioner in the room and its suitable type.

Model selection

This question comes up first. The air conditioner in the bedroom should be quiet, powerful, but not too expensive and stylish.

There are a number of factors to consider before purchasing.

Room area. The power of the device will be directly related to the square meters in the apartment. If the room is small, then choosing a large air conditioner will be inappropriate. The dimensions of the device must correspond to the size of the bedroom.

Device cost.Stores offer many brands of air conditioners with different characteristics. In this matter, the main thing is not to overpay, but not to save too much. Otherwise, the wrong choice will negatively affect not only the comfortable indoor environment, but also the health of the household.

Conditioner shape. Devices can be floor-standing (mobile, stationary) or wall-mounted. The first option has its advantages, for example: such an air conditioner can be moved from room to room if necessary, it is suitable for a small bedroom, the device does not need to be installed. But this device cannot be called silent, during its operation the compressor heats up, so the air itself heats up.

Personal preferences. Everyone wants the air conditioner not only to fulfill its purpose with high quality, but also to look stylish in the interior, harmoniously complementing the atmosphere. It happens that the model with the worst characteristics has an attractive appearance, and a nondescript, at first glance, air conditioner can have a high-quality set of characteristics.

It is important to find a device that combines an attractive shape with internal filling.

In general, any air conditioner must have certain characteristics.

Quiet mode. None of the family members will like to sleep under the loud sounds of the device. Therefore, for the bedroom, you need to choose silent models with the ability to reduce and fix the noise level.

Temperature night mode. Setting such a timer is important for creating comfortable conditions. In addition, this saves energy. The temperature is maintained and the device turns off automatically.

Ionization.Not all air conditioners have this system, but specially charged particles in this case will contribute to the good condition of the household, which can be compared with cheerfulness from visiting a waterfall, sea coast or mountain slopes.

Dehumidification. With the help of such a system, the air conditioner will help get rid of excess moisture. Everyone knows the unpleasant state of high humidity: a person is stuffy, he can hardly breathe. Air conditioning in this case will help to make the air dry.

Cleansing. Some modern models are equipped with a filter system, thanks to which the air is cleaned of various aromas and dust. In some air conditioners, the level of filtration is so strong that even dust mites are eliminated. Such a function is the best suited for people suffering from allergies to dust.

Air heating system. The so-called winter block will be necessary to warm up the room on cold winter nights. Thus, with one purchase, you can combine an air conditioner with a heater.

Conclusions and useful video on the topic

Rules for laying the route of the air conditioner, materials and equipment necessary for the work:

Laying the air conditioning route is a very important event, since the performance and durability of the operation of climate equipment largely depend on the correctness of the work. Most of the work is quite possible to do with your own hands, this does not require any special skills and special equipment.

If you go further, you can independently carry out pressure testing and refueling of the system, but here you already need to carefully consider and decide whether it is worth spending money on purchasing additional equipment or resorting to the services of installers.

But the cost savings will be obvious anyway, because laying the route is a rather expensive undertaking, especially if gating is used and pipes are hidden in the walls.
