How to choose the right air conditioner
The cooling output of all air conditioners is measured in BTU's. (British Thermal Units). It is very important that you choose an air conditioner with a BTU output which is high enough to cool your whole room.
To work out how many BTU's are needed to cool your room, follow the simple calculation below:
Room Width x Length x Height ( measure
in feet ).
This gives you your room size in Cubic Feet.
Now multiply your cubic feet figure by 5. This will give you your required
BTU figure.
For example, room size 12ft x 15ft x 8ft = 1440 x 5 = 7200 BTU cooling requirement. (These calculations are only a rough guide and allow for a room with two or three people and perhaps a photocopier and computer. For each additional person or PC add another 400 BTU's to your total.)
WARNING.If you choose an air conditioner whose BTU output is less than that required for your room, it will only work as a 'spot cooler' and will not reduce the overall temperature of the room.
Why use Breathing Space?
We stock a huge range of brand name
air conditioners from 7200 BTU's to 24000 BTU's. All at competitive prices.
You can choose to buy or rent. Professional advice is on hand, so you
get the right product first time.
Portables come in two designs:
Monoblocs
have cooling outputs of up to 9000 BTU's. You simply hang the flexible
exhaust hose out of a window, through a wall or into a ceiling void to
expel the warm air.
Split Units are more powerful, with outputs from 9000 up to 24000 BTU's. Instead of a flexible hose to expel the warm air, they have a separate condensing unit which hangs out of a window or is fixed through a wall. A flexible cable connects it to the main unit.
