The three main parts of the air conditioning unit are:

•    Compressor
•    Condenser
•    Evaporator

The fluid present in the unit arrives at the compressor as a cooling agent. The compressor then squeezes low-pressure gases and the molecules are packed in the fluid closer together so that they move faster with high energy levels and temperature. The compressor becomes hot because the fluid enters the condenser with high pressure leaving the compressor. It changes from gas to a liquid under the high pressure.

The liquid enters the evaporator and by the time it comes back out, its pressure drops and begins to evaporate into a gas. This is when air conditioning starts to work by extracting the heat from the air around it making it cooler. The fan is connected to the evaporator so that it circulates the air evenly inside the building or a house.

The process happens repeatedly with the fluid entering the compressor. The thermostat turns off when the temperature has reached the right setting. If the room starts to warm up again, then the thermostat turns on the air conditioner so that the temperature of the room becomes cooler.

It is necessary to understand an air conditioner’s mechanism since it will help you make an informed choice.
