The first aircon was developed in 1902 by Willis Havilan Carrier who was an engineer then. It was built to solve humidity problems in a printing plant.
An Aircon works like a refrigerator, instead of cooling a small insulated space, the aircon cools an entire home or organisation space. The aircon system use chemicals that convert gas to liquid and back to gas again. Chemical is used to transfer heat from the air inside a space to outside.
An aircon is made up of 3 main parts, compressor, evaporator and condenser. Compressor and condenser are usually the ones located outside the house or enclosed space. While the evaporator is inside the house.
Liquid fluid arrives at the compressor as low temperature cooled air, then the compressor will squeeze the fluid. This cause the molecule of the liquid fluid to pack closer together. The closer it becomes the higher energy and temperature it becomes.
The liquid fluid exits the compressor as high temperature gas and flows into the condenser. Look at the aircon system outside your house, the metal fins all around disperse the heat away.
When the liquid fluid leaves the condenser, the temperature is cooled down and changes from gas to liquid under high pressure. The liquid will flow into the evaporator by a tiny narrow hole and evaporate into gas.
The evaporated gas extracts heat from the air which is required to turn the liquid to gas.
The evaporator is connected which is a fan that circulates the air into the house. This continues over and over again until the room reaches the temperature you set to.
There you have it, now you know how does an aircon work. For more information stay tuned to our “Home Tips” page.
