The principle of the air conditioner

Hot, stuffy summer ... It is 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, users will be interested to know what the principle of the air conditioner is.

Air conditioner and its device

If you recall the school physics course and the topic of absorbing heat by liquid, you can get a clear example of the operation of the air conditioner. At school they showed 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 used in modern technology. It is the basis of any split system. Modern air conditioners are equipped with the most advanced technologies that help control airflow and purify air.

To understand the device air conditioning system split, you need to consider it in more detail. At the air conditioner main parts are a condenser, a compressor and an evaporator. They are joined together by copper pipes with aluminum partitions and form a refrigerant circuit. It circulates a mixture of freon and oil, which is necessary for the compressor. Copper tubes are called heat exchangers. For acceleration of the process, air is pumped in them by means of special fans. The process begins with the entry of a gaseous freon from the evaporator into the compressor, which is supplied at a low pressure of 3 to 5 atmospheres. Its temperature is from 10 to 20 degrees. The pressure of Freon reduces the compressor and brings it to 15-20 atmospheres, after which freon is heated. It reaches 70-90 ° and then enters the air conditioner. The air of ordinary temperature blows the condenser and cools the freon, which passes from the gaseous state to the liquid, releasing heat. This principle of the air conditioner and provides cooling of air in the room. But the air conditioner can work and creating heat in the room. This happens when the external evaporator, placed outside the room, plays the role of a condenser. When the cold is provided in the room, everything is the other way around. 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 spiral system operating in this manner is called a "reverse 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 still mobile options. Mobile (they are also floor) differ from others in reliability, ease of use and ease of installation. They are used in offices, in cottages in production premises. Outwardly, this air conditioner looks like a bedside table with wheels, thanks to which it can be easily moved to any place. It can be noted that the principle of the air conditioner Allows you to cool, drain or warm air in the room. To install a floor air conditioner, it does not take much time and 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 in the rest - the process of installing the air conditioner is no different from a conventional electrical appliance. After purchase - plug in and use.

Considering the outdoor air conditioner, the principle of its operation can be compared with the air conditioning system split and find differences. The floor air conditioner consists of two units - the evaporator - to cool the air, and the condenser - to drain the heat. Heat from it on the corrugated hose is taken away at the door, window or window. Ventilation can be used for this purpose. With a large capacity of the floor air conditioner (more than two and a half kW) and a channel serving for the removal of heated air, more than two meters, it is recommended to ensure forced airflow, which requires an additional unit with a fan placed outside the room. In winter, the outdoor air conditioner heats the rooms. Its power usually does not exceed four kilowatts.

Air conditioning can bring comfort and comfort to the house, creating the right temperature and humidity in the room. Knowing the principle of the air conditioner, you can notice its failure in time.
