A Complete Guide On Air Conditioners
The air conditioning is a system that allows to modify the temperature of a room or cabin in addition to dehumidifying it . This is a cooling system that is generally used to cool the environment at times of the year when these temperatures are very hot and high.
This device is installed in homes, stores and premises and in most enclosed spaces with the intention of generating a fresh and renewed air. This system offers great comfort in daily life, since the people who buy it will not have to go through the heat.
On many occasions, people call air conditioning to heating systems. This is a mistake , since air conditioning and heating are antagonistic mechanisms, despite the fact that many air conditioning units bring the option of cooling and heating the place where it is placed.
Operation of air conditioning
The operation of an air conditioner is complex, because several physical and chemical changes occur before the device can expel cold air. To correctly explain the operation of an air conditioner, you must first explain what happens in your outdoor unit, since it is in that unit where the cooling process begins.
In the outdoor unit of an air conditioner is the compression engine , which is in charge of compressing the gas, the first step in the operation of an air conditioner. When this gas is compressed by said engine, it goes into liquid state and its temperature increases remarkably.
After this, the gas is driven into the condenser, which is the radiator that is in the outside machine. It is in this part of the process that the sub-cooling task begins , which consists in stealing all the heat from this liquid gas that has just arrived. This is the reason why the outdoor units of the air conditioners expel hot air.
When we remove the heat from the liquid gas, it partially begins to pass into a gaseous state , but not completely. In this way, what reaches the expansion valve is a gas mixture in liquid and gaseous state . Once in this valve, the operation is the same as that of a spray deodorant: there is a liquid inside the can and, when we press, the liquid becomes gas and goes out to a cold temperature.
Thus, the expansion valve produces a pressure drop in the refrigerant, which causes the pressure to decrease and, therefore, the liquid gas to go into a gaseous state and its temperature to decrease further .
After passing through the expansion valve, this air, which already has lower pressure and temperature, goes to the evaporator that is in the indoor unit of our air conditioning. In this indoor unit, the air leaves the room cooling and, at the same time, removing heat from the refrigerant gas, which is in said interior unit.
Thus, the heat that we remove from the room with the gas is absorbed by the compressor, so that it can serve to cool the gas that returns to the outdoor unit. The repetition of this process is what achieves that the air conditioning can reduce the temperature of the room or the place where it is, until reaching the temperature that has been marked on the control that controls the device.
A confusion that many people have about the operation of an air conditioner is to think that the air that it expels will leave at the temperature that is marked in the control that controls it . On the contrary, the degrees that are marked on the remote control indicate to the air when it should stop reducing the temperature of the room .
That is, if a temperature of 20 ° C is marked on the control of an air conditioner, the air will expel cold air until it detects that the room is at that temperature. Once the temperature marked on the control is reached, the air will stop, until this temperature varies, at which time it will start again.
In order for an air conditioner to detect the temperature of the room in which it is located, it will have to have a thermostatic probe. This component is responsible for ordering the air conditioner to stop at the correct temperature. This piece is located near the filters of the interior of the air conditioning.
Air conditioning always brand
We recommend that you always buy an air conditioner, for example Daikin or Mitsubishi Electric . These internationally prestigious brands invest millions in improving energy efficiency and have excellent quality.
