Air conditioning is something almost everybody expects to find in a vehicle, and more and more this is becoming the case for buildings as well.

The most common form of air conditioning is done through the use of vapour compression. This is where air is compressed, and then heat is extracted from the space, so that cool air is created. You can find this method being used in vehicles, commercial properties, in industry, or in food refrigeration.

Of course, you will find air conditioning units based off of compressed air technology everywhere, but depending upon your needs you will require different sized units. For instance, a massive oil refinery will require a massive air conditioning system, while a car will only require a very small unit. It is very important that you get the right sized model, as they can be very energy-inefficient, costing you money, and causing greater pollution.
