How does aircon work?

Wondering ‘how does an aircon work’? It’s not as complicated as you might think. First of all, an air con has two main purposes: to cool or warm a room, regulating temperature to keep you comfortable. It can also change the humidity and quality of your air, depending on the machine you have.

The system works by using an outdoor and indoor unit. The outdoor unit has a compressor that circulates the refrigerant, switching it to a liquid from a gas. The indoor unit then takes the air inside your room and passes it across evaporator fins, which are designed to transfer heat. It’s at this point that the refrigerant turns back from liquid into a gas, taking heat from the surrounding air to do so. The air is cooled by this and circulated back into your room. It’s a pretty smart system!
