Split System Air Conditioners

Split System Air Conditioners

Split systems are generally used to air condition houses, although they are equally suitable for commercial environments such as small shops and small offices. They can be used for both cooling and heating.

A single split system air conditioning system comes in two pieces.

  • One piece contains the compressor, condenser and a fan, and is installed outside the building.
  • The other piece has an evaporator and a fan. The two are connected by piping that carries the refrigerant.

A multiple split system air conditioning system comes in two to nine pieces (depending on brand). One piece always contains the compressor, condenser, and a fan and the others each have an evaporator and a fan. Again, piping carrying the refrigerant needs to connect the exterior unit with each interior unit.
Selecting the right model

This is where you really need professional advice, especially if you’re looking at a multi-split system. A unit too large will consume unnecessary additional power, whereas a unit too small won’t deliver the cooling you expect, so you won’t feel completely comfortable.

When asking for recommendations, it’s a good idea to measure the room (or rooms) you wish to air condition before speaking with us.
Here’s a quick two-step guide to help you work out what size system you need:

  1. Calculate the area of the room.
  2. Multiply the area by 150* watts.

For example, your room is 6m by 5m:

6m x 5m = 30 m²
30 m² x 150 watts = 4500 watts (4.5Kw)

*It’s also useful for us to know which direction the rooms face: southerly facing rooms require less cooling in summer but more heating in winter. If the room is facing West, or if it faces North and has large windows, use a factor of 180 watts for your calculation. In our example above, a Westerly facing room would need a 5.4Kw system.

If more than two people regularly occupy the room in daylight hours, add an extra 200 watts for each additional person.
