What is the air conditioning?
The process of air conditioning involves regulating the temperature and humidity of air in a room or enclosed space. Under ideal conditions, it accomplishes all this simultaneously. The most common objectives of conditioning are to increase or reducing the humidity and temperature of the air, despite the procedure can likewise include filtration and refreshing the air. It is one of the most used electrical appliances today, mainly in the summer for the simple reason that it effectively helps to cool the air that is used either in the office or at home. There is another type of refrigeration which is considered industrial, since it serves to cool large areas such as industrial refrigerators, which are associated with maintenance chambers of edible products such as fruits, dairy, among others. As the taste and desire for satisfaction increases, humans have sought ways to improve and control both the external and the internal factors affecting a comfortable living.
Components of the air conditioning system
The air conditioning system has the following components, including:
- Indoor unit or Split: Contains the evaporator, which extracts the hot air from the room and transmits it to the refrigerant gas. This unit also has temperature sensors that are connected to the thermostat.
- Outdoor unit: Contains the condenser and the compressor. This unit is the one that releases the hot air and, in it, the refrigerant gas passes from gas to liquid.
- Other components: Apart from these two units, you can also find, inside an air conditioner, other components: an expansion valve, a compressor, refrigerant gas, and a thermostat.
The functioning of an air conditioner
In general, an air conditioner uses a refrigerant circuit, not to bring cold air into the room, but to extract hot air from the room. The compression refrigeration system is the most commonly used, both domestically and commercially. This system follows several steps:
- The compressor in the outdoor unit compresses the gas. The gas, when compressed and change to the liquid state, increases its temperature.
- This coolant goes to the condenser, and the subcooling process is carried out, emitting heat to the outside, like a radiator. It absorbs the heat from the liquid and converts part of the liquid back into a gas, leaving another part as a gaseous liquid.
- This mixture passes to the expansion valve, which lowers the pressure and temperature of the gas.
- Then, the mixture with the decreased pressure and temperature passes to the evaporator, which reheats the gas in a process called superheating. This happens because the gas has a lower temperature than the temperature of the room, so the heat leaves the room to cool the gas and leave it at the same temperature.
- Hot air enters the circuit, goes to the evaporator and transfers its heat to the refrigerant gas, cooling the room.
- Then, the compressor absorbs the heat of the refrigerant gas and expels it to the outside.
Broadly speaking, this is a process that continues, and that is repeated step by step until the room cools. Then, the thermostat detects it and stops the device until its heat sensors detect that the temperature has risen and the entire circuit is activated again.
