What is an Air Conditioner and How Does it Work?

We all know what air conditioning is and that it keeps your business the perfect temperature all year round, but have you ever wondered exactly how this technology works?

The process of cooling the air in your offices is actually mainly based on simple scientific principle, aided by mechanical systems. Take a look below at how exactly air conditioning works to cool your business:

Air conditioner components

An air conditioning system is made up of a range of parts that work together to cool the air around you. There are four main parts:

    • An evaporator

This receives liquid refrigerant

    • A compressor

This is a pump that pressurises the refrigerant

    • A condenser

The condenser facilitates the heat transfer

  • An expansion device

This regulates the refrigerant flow into the evaporator

The compressor and condenser are usually located outside and the evaporator and expansion device are located inside.

How it works

Simply put air conditioning systems work in a similar way to refrigerators as they remove the hot air from an area and replace it with cool air. All of the hot air is then expelled outside of the building.

Our step-by-step guide details simply how the technology works:

1.Heat absorption

The evaporator coil absorbs the warm air from inside your building through a vent. As this contains liquid refrigerant, this cools the air that is absorbed from the room. The passing air then changes from a liquid into a gas and travels along the pipes to the compressor.

2.Compression of the gas

The compressor then reduces the gas’s volume by squeezing it between two solid objects. This means that the temperature and pressure of the refrigerant is raised in preparation for the condensing process.

3.Expulsion of heat

The refrigerant is then transported to the condenser outside and is expelled into the air. This then takes the temperature of the refrigerant and changes it back into a liquid.

4.Repeat the process

As the heat from the refrigerant has now been removed, it can travel back indoors to the evaporator. The process then continues to repeat itself to keep the air inside your building cool.

Is this the case for all types of air conditioning units?

There are several types of air conditioner that we work with, including:

  • VRF
  • Wall mounted split systems
  • Ducted systems
  • VRV
  • Cassette split systems
  • Air source heat pumps
  • Close control systems
  • Mitsubishi Electric Ecodan

Although all of the units are different and have different functions, the general principle and process of air conditioning stays the same throughout.
