How Air Conditioning Works


Air conditioning is a modern and efficient system designed for heating and cooling rooms in both domestic and commercial buildings.

As well as the potential to reducing energy costs, air conditioning is an excellent option for replacing electric heating systems or when radiator pipe work isn’t available. They are also an efficient heating source for rooms such as conservatories.

Air conditioning can change the temperature, humidity or general quality of the air. As well as heating your building, they are also used to cool spaces by drawing heat energy out of the building and then replacing the air inside with cooler air.

In a split system, the compressor condenses and circulates the refrigerant through the outdoor unit, changing it from a gas to a liquid. The liquid is then forced through the indoor evaporator or cooling compartment.


The indoor unit’s fan circulates the air to pass across the metal evaporator fins which exchange the thermal energy with the air around it.

There, the refrigerant turns from liquid into vapor, removing any heat from the surrounding air. As the heat is removed from the air, the air is cooled and blown back into the house.

From that point, the condenser or outdoor unit then turns the refrigerant vapor back into a liquid, removing any heat. By the time the fluid leaves the evaporator again, it is a cool, low-pressure gas, eventually returning to the condenser to begin its cycle all over again.


This process is repeated until the room reaches the desired temperature, as programmed by the thermostat setting.
