The principle of operation of the air conditioner

Hot stuffy summer ... It was at such a time that the presence of an air conditioner and its proper operation are very relevant. After all, the main purpose of this technique is to create a cool climate in the room. And, of course, it will be interesting for users to find out what is the principle of the air conditioner.

Air conditioning and its device

If we recall the school physics course and the topic on the absorption of heat by a liquid, you can get a good example of the operation of an air conditioner. The school demonstrated the evaporation of cologne from the hand, which is accompanied by a feeling of coolness on the skin. It is this principle of the air conditioner that is used in modern technology. It is at the heart of any split system. Modern air conditioners are equipped with the most advanced technologies that help control air flow and purify the air.

To deal with the device of an air conditioner system split, you need to consider it in more detail. In an air conditioner, the main parts are a condenser, compressor and evaporator. They are interconnected by copper pipes with aluminum partitions and form a refrigeration circuit. It circulates a mixture of freon and oil, which is necessary for the compressor. Copper tubes are called heat exchangers. To speed up the process, air is pumped into them using special fans. The process begins with the ingress of gaseous freon from the evaporator into the compressor, which is supplied under low pressure of 3 to 5 atmospheres. Its temperature is from 10 to 20 degrees. The pressure of the freon reduces the compressor and brings it to 15-20 atmospheres, after which the freon is heated. It reaches 70-90 Β° and then enters the air conditioner. Air of ordinary temperature blows across the condenser and cools the freon, which from a gaseous state passes into a liquid state, thus generating heat. This principle of operation of the air conditioner and provides cooling air in the room. But air conditioning can work and create heat in the room. This happens when an external evaporator placed outside the room plays the role of a condenser. When the room is cold, the opposite is true. To increase the functionality of the air conditioner, a four-way valve is added to its circuit. It allows you to produce both cold and heat. A split system that works in this way is called a β€œreverse cycle air conditioner.” He transfers heat from the room to the street and returns it back.

Types of air conditioners

In addition to wall and window air conditioners, there are also mobile options. Mobile (they are also floor standing) are distinguished from others by their reliability, ease of use and ease of installation. They are used in offices, at dachas in industrial premises. Outwardly, such an air conditioner resembles a bedside table with wheels, thanks to which it can be easily moved to any place. It can be noted that the principle of operation of the air conditioner allows you to cool, drain or heat indoor air. To install a floor air conditioner, you do not need to spend a lot of time and have special knowledge. The main thing is to place the mobile device at a distance of thirty centimeters from the walls and place it on a flat surface. And the rest - the installation process of the air conditioner is no different from a conventional electrical appliance. After purchase - plug in and use.

Considering the floor air conditioner, the principle of its operation can be compared with the air conditioner of the split system and find the differences. The floor air conditioner consists of two units - an evaporator - for cooling the air, and a condenser - for removing heat. Heat from it through a corrugated hose is removed to a door, window or window. For this purpose, exhaust ventilation can be used. With a large capacity of the floor air conditioner (more than two and a half kW) and a channel serving to remove heated air, more than two meters, it is recommended to provide forced outflow of air, for which an additional unit with a fan located outside the room is needed. In winter, outdoor air conditioning heats the room. Its power most often does not exceed four kilowatts.

Air conditioning is able to bring coziness and comfort into the house, creating the desired temperature and humidity in the room. Knowing the principle of operation of the air conditioner, you can notice its malfunction in time.
