Air conditioners provide much-needed relief in otherwise hot and humid weather. Apart from this, ACs have evolved so much that now, they can eliminate contaminants such as viruses and bacteria from the air as well. But do we know how these home appliances actually work? If you too are curious to find out, read on.


How does an AC work?

In any type of air conditioner – be it Window, Single unit or Split AC – there are three crucial components. These include the evaporator, compressor, and the condenser. These three vital components work in tandem to produce the cooling effect.

Many might believe that an AC produces cold air to bring down the temperature in a room or an area. But, that is a slightly skewed perspective. In reality, an AC strips the air of its heat to lower the temperature, as well as humidity.

An air conditioner has two connected coils made of either copper or aluminum. These coils have a fluid continuously flowing inside them known as the refrigerant. One unit of the AC is inside your room while the other one is located outside. To understand working, let’s take a closer look at them.

Inside the room: It is also known as the cold side of the system, and includes the evaporator. A blower/fan sucks in the hot air inside the room and circulates it through the evaporator. Heat is absorbed by the refrigerant and the liquid refrigerant turns into gas. The cooled air is then dispersed back into the house.

Outside the room: It is also known as the hot side of the system and consists of the condenser and the compressor. It is the main engine of the entire setup which moves the hot gaseous refrigerant from the evaporator to the condenser, where the hot coils release the collected heat into the outside air. This refrigerant after losing the heat again turns into liquid and the compressor moves it back to the evaporator. And this cycle continues.
