How many times in the summer when the heat comes, or in the late autumn, when the apartment is uncomfortable without heating, we all remember that we were going to install an air conditioner, but our hands did not reach? You must admit that summer will come in any way in the spring, and if the issue is not resolved, then we will again languish from the heat. No ventilation or fans, and in winter heaters will not save us.

We must still decide and address the issue of choosing an air conditioner with a whole list of convenient functions that will make our life more comfortable. We will help you navigate the sea of ​​various climatic equipment, tell you where to put the air conditioning, and how to decide on the choice of the best place for installation.

Optimal air exchange in the apartment

According to statistics, a person spends in enclosed spaces at work or at home from 16 hours a day, so the issue of ventilation and air renewal is so important.

In order for a healthy and comfortable microclimate to reign in the house, several steps should be taken:

  • check the operation of the exhaust system
  • use supply devices if necessary
  • install air conditioning

The proper functioning of the exhaust ducts can be checked in an elementary way using a strip of paper, during normal operation, the air flow draws it to the ventilation grille. The “repulsive” effect signals the presence of reverse draft.

Checking traction in the natural ventilation hole
An experiment with a sheet of paper should be done twice: with the window open and closed. In such a simple way, you can find out the cause of poor traction, poor air flow into the room or problems with the ventilation duct.

To solve the problem, it is advisable to insert a fan with a check valve. The next step will be the installation of inlet valves in plastic windows.In the case of obsolete wooden frames, the issue of air flow is solved spontaneously, without valves.

And finally, the final step. For complete comfort, i.e. getting cool in the heat and heat in the cold, the climate technology is installed (after deciding on the choice of the model and location of the air conditioner, as the efficiency depends on competent placement).

General information about air conditioners

In order to maintain the optimum comfortable temperature in the house (usually from 18 degrees to 25), it is necessary that both the climate and ventilation systems work smoothly and complement each other. Correctly assessing the needs of the premises and making a rational choice will help understanding the mechanism of action and features of climatic equipment.

Standard equipment classification

By design, air conditioners are divided into two classes:

  • monoblock (represent a system, all components of which are immersed in a common housing);
  • split systems (include two interacting blocks: external and internal).

The first class includes floor mobile models and window air conditioners. They are distinguished by a simplified design, extremely simple installation and low price. Compact window units are not very popular with us due to noisy work and inconvenient installation, they darken the room and spoil the view of the window.

Mobile air conditioners, small but heavy (up to 50 kg of installation with a hose), due to their mobility are in demand among summer residents, but the disadvantages are the small cooling area and high noise level.

Floor air conditioner for summer cottage

Among a variety of floor-mounted mobile air conditioners, models without a corrugated hose appeared; they are much quieter, more mobile and safer (the hose, when heated to 60 degrees, can burn).

In contrast to the above options, split systems are characterized by small size and low noise level.

Channel and cassette air conditioners mounted in the space behind the false ceiling and false walls. Column and precision floor mounting is required; these types of air conditioners belong to semi-industrial systems and are used for installation in technological rooms, museums and shops, restaurants and hotels.

Wall split systems are designed for rooms from 15 to 90 square meters. meters, they are considered the best air conditioners for arranging an apartment.

Guidelines for choosing a climate unit

In order for the air conditioner to function for a long time and properly with maximum efficiency, the necessary conditions must be met:

  1. choose a model suitable for the parameters of this room;
  2. qualified installation of the device;
  3. use the unit in accordance with the operating rules; carry out regular maintenance.

In the process air conditioner selection it is necessary to take into account such characteristics as the total area of ​​the room and the number of people in it. It should take into account the orientation to the cardinal points and the presence of windows with shutters, as well as the power of the heat-generating equipment.

For cooling 10 square meters. meters, on average, 1 kW is required, therefore, when calculating the necessary refrigerating power, you need to divide the room area by 10; in addition to this main parameter, the remaining dimensions also affect the value.

In order to find out which air conditioner is better to choose, you need to consider the main selection factors: type of design (split system or monoblock), use (semi-industrial or domestic) and unit class (budget, medium or high-end)

For a room located on the south side, with panoramic glazing and a lot of equipment (computer, refrigerator, TV, etc.), it is supposed to increase the calculated value of optimal cooling by 20%. An insufficient capacity air conditioner, even with proper operation, will not cope with its functions.

Split system features

The most necessary and demanded functions of a split system, for which the buyer installs climate equipment, are heating, cooling and ventilation, drainage and air purification.

For proper use of the function of heating the premises, use the add-on “all-weather unit”, which is responsible for heating the crankcase and reducing the risk of compressor wear.

In ventilation mode, it is convenient to have several speeds. Then, without changes in temperature, it is desirable to adjust the circulation force of stagnant air masses. With an increase in the humidity level, a dehumidification mode will help, allowing to stabilize the indicator and prevent its negative impact.

Additional options such as a timer, regulation of air flow directions and night mode are also useful, the use of which will add comfort when operating the air conditioner.

Air conditioner pre-filter
The main task of the coarse filter is to prevent air conditioner pollution, the higher its quality, the longer the life of the system. In many models, sensors, indicators and forced shutdown of equipment are introduced to control clogging.

However, one of the most important and necessary functions is to clean the air before serving. This occurs during the filtration process using a standard coarse filter (a plastic mesh that needs regular inspection) that traps dirt, large dust particles and animal hair.

Fine filters that retain particles of several microns are also used. Some models complement carbon, removing unpleasant odors, and electrostatic, which eliminate various allergens, fine dust and pollen from plants.

Wall conditioner options

Filters, a 3 or 4-speed fan, horizontal blinds and a condensate tray, necessary to perform all of the above functions, are components of the indoor unit of a wall-mounted split system (or simply a “domestic air conditioner”).

Wall type of air conditioner considered the most common and deservedly popular for a private house and apartment, with a capacity of 2 - 7 kW it cools small rooms from 15 to 75 square meters. m

Wall-mounted air conditioning on the wall in the apartment
For comfort when using the air conditioner, accessories are produced: wired and wireless remotes, drainage pumps for condensate collection and deflectors (protective shields). Screens scatter the cold flow of air, they are made of transparent plastic for ceiling, wall models and ventilation grilles.

Small sizes (height from 20 to 30 cm, depth from 16 to 20 cm and width within 0.7-1.6 m), complete with simple installation and easy operation have become the main advantages of this model. The advantage is the low noise level achieved by installing the compressor on the street side.

When working on space heating, the external unit acts as an evaporator, and the internal one as a condenser. In the case of cooling mode, each unit performs the opposite function.

Traditional block placement

The outdoor and indoor units of the wall-mounted air conditioner communicate with each other using freonotrassy. These are copper tubes with circulating freon (R22, R410a or R32). The control and power cables, as well as the plastic tube for condensate discharge to the street, are still being laid.

The optimal length of the line between the units should be no more than 5 m (this applies to inverter air conditioners more than others), in cases of a higher value, freon refueling will be required. This limitation affects the choice of location of the climate system, where it is correct to install the external and internal air conditioning units in the house.

The simplest “standard” installation option implies placing both units in accessible places, with a communication length of not more than five meters (PVS, flex and pipe), and a drainage tube - three meters.The thickness of the brick wall between the blocks should not exceed 0.8 m, and the walls of concrete 0.6 m.

Mounting the outdoor unit on the facade
The most convenient way of arranging a wall-mounted air conditioner is considered to be a “sandwich”, when only the wall thickness separates both blocks, however, the length of the route is less than 3 meters is strictly not recommended. In this case, without any shortening, the excess line must be wrapped with a ring behind the outdoor unit.

The inner part of the system is fixed in the upper part of the wall near the window, the outer part with the compressor is under the window, the distance between them is directly proportional to the decrease in power of the unit.

Based on this, the smaller this gap, the more efficient the air conditioner. Therefore, it is desirable to place the indoor unit on the same wall as the external one. But at the same time, each manufacturer calculates a personal maximum between the blocks.

Outside Location

The external unit of the wall-mounted air conditioner is one of the most important parts of a split system. It includes the following elements: compressor, fan and condenser, control board and four-way valve. In order for all these devices to interact in a high-quality manner and to perform their functions as efficiently as possible, it is necessary to take the placement of the unit seriously.

After choosing and acquiring, each consumer is faced with the task of how and where to correctly hang or place outdoor air conditioning unitas the location and conditions are very important.

In the selection process, the following parameters must be taken into account:

  1. device weight (usually between 20-70 kg);
  2. wall material and the ability to blow air;
  3. access without interference for maintenance;
  4. protection against environmental factors.

Installation of the outdoor unit is most often done on the outside of the building, while it is necessary to check the strength of the wall section (fasteners to a dilapidated surface are prohibited). The quality of fastening is also strictly controlled in the presence of a layer of insulation materials (anchors and brackets are used with a large margin of safety).

Standards for installing an outdoor air conditioning unit
When installing the outdoor unit, close attention should be paid to the level of fixation, observing the accuracy of horizontal and vertical lines, as a necessary condition for the correct operation of the compressor.

For free air circulation and inadmissibility of overheating, the unit is placed at a distance of at least 15 cm from the wall and 20-30 cm to the nearest obstacle, preferably on the shadow side. Installation under a window with an opening sash is made for ease of maintenance.

In rare cases, when mounting on the upper floors, the outdoor unit is placed on the roof or a non-glazed balcony (provided that there is sufficient airflow).

Optimum internal component location

The installation location of the indoor unit should be determined taking into account the rules for placing the air conditioner in the house (room) and the features of the functioning of the equipment.

Therefore, when choosing the optimal placement of the block, it is necessary to provide compliance with the requirements:

  1. distances to the external block, ceiling, walls and other obstacles;
  2. the presence of space to heat sources;
  3. free circulation of the air flow of the system;
  4. the likelihood of a person being present at risk.

Air is taken from the room through the upper part of the device, in connection with this there must be space to the ceiling and side surfaces of at least 10-15 cm. Installation over horizontal surfaces (shelf, chest of drawers or cabinet) is not recommended, if the distance is less than 0.7 - 1.0 meters.

Due to the fact that the temperature sensors of the unit react to nearby air currents, it is impossible to mount the air conditioner near radiators, a boiler, a gas stove and other heat resources, as this will cause the air conditioner to work continuously for cooling and lead to rapid wear.

And the main problem in finding a location for climate technology is the least likely negative impact on human health. Each room of the apartment has individual requirements, however, the main condition must be met everywhere - the cold stream should not go to places where households have been for a long time.

The highest concentration of chilled air is observed at a distance of 2-3 meters from the device, then the cold dissipates.

Accounting for airflow direction
In the bedroom, the air directed from the air conditioner should not fall on the heads or backs of vacationers. If there is not enough space, for the possibility of adjustment, you should choose a model with multidirectional air flows.

On this basis, in the bedroom, air conditioning is installed on the wall at the head of the bed, on the side of the bed. In the living room, the optimal place will not allow the sofa and dining table to get into the three-meter risk zone. In the children's room, it is recommended to turn on the air conditioning during the absence of the child.

In the kitchen, with an abundance of equipment (radiator, refrigerator, stove), window air conditioners and corner compact models are often chosen. However, due to unstable humidity with temperature, the placement of climatic equipment that is not adapted to such conditions is prohibited by manufacturers. The problem is usually solved by installing a fan in the hood.

Private air conditioning options

When planning and calculating the air conditioning system in a private house, they are usually guided by the same rules as in other rooms - the size of the area, sources of excess heat, the number of people living, etc.

But during the construction of a new house, there is a chance to carefully consider the location of both the furniture and the devices of the ventilation and air conditioning systems so that the monitoring sensors are correctly placed and do not misinform the climate system.

In choosing a model of equipment for a private house, much more options are considered (many types of air conditioning in conventional apartment buildings are difficult to install).

Therefore, in addition to standard split systems, channel and cassette air conditionersusing the attic or attic. They use universal ceiling-floor or multi-systems (for country houses from 150 sq. M. Multi-zone VRF and VRV systems).

Location of the external unit split system
Installation of the outdoor unit in a country house is often done on the blind area, on the veranda or on a flat roof, in this case it is better to choose inverter air conditioners with reduced noise level.

And finally, to choose where to install the air conditioner correctly so that it harmoniously looks in the apartment, several proven decorating methods will help:

  • air conditioning decoration;
  • disguise behind a decorative screen;
  • placement in a niche or on an open shelf.

If there is no niche in the wall, if there is no screen or shelf in the right tone, simple alternative design options are possible.

Air conditioning masking option
The decorative painting method helps to achieve a harmonious combination of air conditioning and interior. The drawing is varnished, does not fade, it retains its original appearance for a long time.

Photographic printing is pasting the facade of the air conditioner with individual stickers in the tone of the environment. The artist paints the air conditioner case with acrylic paints or a special spray gun with artistic painting. In any case, the air conditioner will be in harmony with the design of the room.

The principle of installing an air conditioner is generally simple, but details and details are important, they will help the equipment work more efficiently, and we feel more comfortable.
