An air conditioning system works by using a refrigerant to cool and dehumidify the air inside a building. The refrigerant is a substance that easily converts from a gas to a liquid and back again, and this property is used to transfer heat from the air inside the building to the outside air.
The air conditioning system consists of several main components: an evaporator, a compressor, a condenser, and an expansion valve. The evaporator is located inside the building, and it is responsible for absorbing heat from the air inside the building. The evaporator contains the refrigerant in its gaseous form.
The compressor is located outside the building, and it is responsible for compressing the refrigerant gas from the evaporator. This increases the pressure of the refrigerant, which in turn increases its temperature. The hot, high-pressure refrigerant gas is then sent to the condenser.
The condenser is also located outside the building, and it is responsible for releasing the heat from the refrigerant gas. The heat is released into the outside air, and the refrigerant gas is condensed into a liquid. The liquid refrigerant is then sent through an expansion valve, which reduces its pressure and temperature.
After passing through the expansion valve, the refrigerant is in its gaseous form again and is ready to be sent back to the evaporator to absorb more heat. This process continues in a cycle, with the refrigerant constantly being cycled between the evaporator, compressor, condenser, and expansion valve.
As the refrigerant absorbs heat from the air inside the building, the air becomes cooler and less humid. This cooled and dehumidified air is then circulated throughout the building by the air handler, providing a comfortable environment for the building's occupants.
In summary, an air conditioning system works by using a refrigerant to transfer heat from the air inside a building to the outside air. This process is made possible by the components of the air conditioning system, including the evaporator, compressor, condenser, and expansion valve.
