How Does Air Conditioning Work?

Air conditioning works by collecting hot air in a room and cooling it. Unlike what some may think, air conditioners (AC) were not originally made for human comfort but to facilitate the manufacturing process of a publishing company. Nowadays, an AC is commonly used during the summer to keep homes and business premises cool. It is designed to work in the same way as your refrigerator.

The only difference between the two gadgets is that an air conditioner cools a large space. The air conditioner works under a simple scientific principle and through some mechanical installations. Some people only associate an AC with cold. However, it involves the transfer of heat in a certain space.

When the hot air in a room is removed, the remaining cold air helps to cool the space. Traditionally, people used different ways of keeping their homes cool during the hot weather. However, modern air conditioners have proven to be more effective in doing the work. Every AC has a thermostat which monitors the temperature in a room to ensure that it remains near the user’s preferred level. In this article, you will understand how the different parts of an AC work. Lets breakdown the different parts of an air conditioner into three sections:

Evaporator

An evaporator works by using a refrigerant gas to collect the heat in a room. The refrigerant gas is responsible for absorbing heat which then evaporates as a gas. The evaporator is located in the indoor unit of an air conditioner. Most ACs use hydrofluorocarbons and hydrocarbon as the refrigerant gases.

Compressor and Condenser

The compression of the refrigerant gases occurs in the compressor by increasing its temperature. It is part of the outdoor unit of your air conditioner. The combined gas law is used in this section as the pressure is increased to increase the temperature.

On the other hand, the condenser coil works by receiving the high pressure and temperature from the compressor. One of the components of a condenser is a hot refrigerant gas. It is used to transfer heat to the outdoor air.

Expansion Valve

Expansion valves also operates under the combined gas law. The expansion valve of an air conditioner helps to lower the pressure of the refrigerant gas used and hence cools it down. Once the pressure has reduced, the liquid changes to a gaseous form. The valve also regulates the amount of the refrigerant liquid that is entering the evaporator.

One of the companies that have become reputable over the years for their air conditioning services are HVAC companies. You can always contact an HVAC professional if you need the services.
