How Does Air Conditioning Work?

Air conditioning

Did you know that in the UK, fewer than 5% of homes have air conditioning?

Air conditioning has become a necessity for living indoors, although it is often taken for granted. If you are wondering, air conditioning works by forcing cold air through a series of filters. Condensers cool the air further, resulting in cooled air blowing out of the vents.

However, how the individual parts function together might seem a bit confusing. Read and learn about how does air conditioning work.

How Does It Work?

In basic terms, air conditioning uses a refrigerant to cool air and circulate it throughout your home. The refrigerant is constantly evaporating and condensing, which helps it to absorb heat from the air.

As the refrigerant evaporates, it pulls heat from the air, circulating through a series of coils. The cooled air is then pushed into your home through a fan.

Air conditioning is cooling and dehumidifying the air to create comfortable indoor air conditions. This is done by removing heat from the air and lowering the humidity. To understand how air conditioning works, it is essential first to understand its science.

The science behind air conditioning is based on the principles of thermodynamics. Thermodynamics studies heat and how it is transferred from one object to another. To cool the air, the air conditioner must remove heat from it.

This is done by using a refrigerant. The refrigerant is a substance that absorbs heat and then transfers it to the outside air.

The History of Air Conditioning

In the early days of air conditioning, people used large blocks of ice to cool down their homes. The ice would be placed in a box with a fan, and the air from the fan would circulate around the room, cooling it down. 

Air conditioning has been around for centuries, with the first known use of cooling occurring in Ancient Egypt. In the early 20th century, air conditioning became increasingly popular, with the first residential air conditioner being introduced in 1914. Today, air conditioning is a common feature in homes and businesses worldwide, and is essential for comfortable living in many hot climates.

How They Produce Cold Temperature

Air conditioners work by using a process called the refrigeration cycle. This cycle removes heat from the air inside your home and transfers it to the outdoors. In order to do this, air conditioners have several components, including:

  • Compressor
  • Condenser
  • Expansion Valve
  • Evaporator

The refrigeration cycle starts when the air conditioner’s compressor compresses the refrigerant, a gas. This increases the refrigerant’s pressure and temperature. The hot, high-pressure refrigerant then flows through the condenser, where it is cooled by the outside air.

The refrigerant then flows through the expansion valve, where its pressure and temperature are reduced.

Understanding How Does Air Conditioning Work

How does air conditioning work? One way to think of how an air conditioner works is that it helps with symptoms of heat exhaustion. By cooling and dehumidifying the air, an air conditioner helps lower the air’s temperature and makes it feel more comfortable.
