Air Cooled A/C Units

Have you ever wondered where the cold air comes from in an air conditioning  unit? Probably not, but if you are thinking about buying air conditioning there are things  you need to know, and take into account, before the installation. You need to  consider where the equipment is going to go and what type of equipment you  need, based on whether it is for office, home, warehouse, small store, two  storey building, high rise etc.

There are thousands of types of air conditioning out there but they basically  fall into two categories – air cooled and water cooled. This article is about ‘air  to air’ or air cooled air conditioning (HVAC)

So, basically, that means that the unit cools using a fan across the coil outside  to get rid of heat. Like all systems there are pros and cons, depending on your  needs. Pros include the fact that they are easily installed, work in many  locations, and come in packages so no piping needs to be run. The downside  can be the noise. Air across the coil and the fan motor make noise, although  the newer units are a lot quieter than the older ones. Dirt can also be an  issue. The air passing across the coil leaves a lot of dust and grime, causing the  unit to lose efficiency over time. Therefore regular cleaning and servicing is a  must.

Air to air is the most common air conditioning used today.
