Understanding the Basics of Air Conditioning

Air Conditioning North Wales

Over the years CRL Group has noticed that there is a distinct lack of understanding for the fundamentals of air conditioning and how they actually work. Most of us think that these devices simply pump cool air into our homes or offices and that is where the complexity ends. However, the air conditioning unit actually removes the warm air and re-circulates it as cool air.


This is comparable to how a refrigeration unit works when keeping your food fresh. The air conditioning unit uses a refrigerant, such as Freon, to execute the cooling function. Any central air conditioning system will include both the cooling and heating of air for whatever the weather may bring, that also cleans the air and controls the moisture levels.

There are several ways to cool your home and with most air conditioning units, the methods are similar or the same. You will have a means of removing the warm air to be turned into cool air, as well as a means of distributing the air between the rooms of your home. This is typically done through a duct system via a temperature controlling system or thermostat.

Thermostat & Compressor

This thermostat that controls the overall temperature of your home through the air conditioning system can easily be preset to adjust itself, according to your preferences as well as the room’s temperature. The thermostat sends a signal to the air conditioning system which is triggered to produce the appropriate air temperature.

The compressor, controlled by the thermostat, is the heart of the system. The compressor “pumps” the refrigerated air through the system and throughout your home. However, its main function is to draw in a low pressure, the low-temperature refrigerant in a gaseous state. The pressure and temperature are raised by compressing the gas, which then flows through to the condenser coil.

Split System

A majority of air conditioning units operate using a split system. To put it simply; they consist of a “hot” side and a “cold” side. There are parts of the system located both inside and outside your home which allow for cold air and hot air to circulate at your own desire.

There is so much more to learn about the intricacies of air conditioning systems. Should you be interested in how air conditioning works and how they can benefit your home or business then do not hesitate to contact the team at CRL Group today.
