How Does AC Work?

Western States air conditioning in AZEverybody knows that an air conditioner keeps our rooms cool during the hot summer days, but how many people know how an AC actually works? Well, not so many. This is one of the subjects that most people find extremely boring. But if you find physics interesting and you are curious about how ACs work, you are in the right place. In this article, we take a deeper look into the inner workings of an air conditioner to help you understand how the piece of equipment helps keep your room cool. Here’s how the entire air condition plays out:

The Cooling Process

The AC unit converts gas (the air inside your house) to liquid and back with the help of a refrigerant and a bunch of coils. The refrigerant then transfers the heat from the air in the house to the outside and then back inside, while absorbing and casting the heat out in the process. This refrigerant- a chemical that quickly transforms from a liquid to a gaseous state, cools and goes back to the home to start the cycle afresh. HCFCs, or hydrochlorofluorocarbons commonly used as refrigerants.

Parts of an AC Unit

Did you know that an air conditioner and a refrigerator have the same working principle? The only difference is that a refrigerator cools within a small, insulated space while the AC cools bigger spaces like our homes, cars, and office buildings. The AC has three essential parts, that’s the compressor, condenser, and the evaporator. The evaporator is located within the house while the condenser and the compressor are placed on the outside.

The evaporator is the part where the refrigerant evaporates. The air inside the home is blown into the evaporator coils by fans inside the house. The vaporized air is passed to the compressor where its compressed to a state of high pressure and high temperature. The hot vaporized air passes to the condenser where its cooled and turned to liquid. The cool liquid now flows back inside the house to the evaporator where it absorbs heat and changes form to a low-pressure gas.

As you can see, the whole process of keeping the air in your home at a comfortable temperature is based on a very simple scientific principle. But you don’t have to know how the AC works to appreciate its benefits. At Western States Home Services, we understand air conditioning and are ready to help you out if your AC is having problems.
