Frequently Asked Questions

Are there any special requirements for the use of portable air conditioners?

Yes. Access to either an opening window, external door or suspended ceiling is essential in order that the hot air exhaust can be ducted out by either a flexible hose or a condenser box. The hose is supplied in standard lengths, extension hoses can be used if required.

How do I install my Portable Air Conditioner?

The 'hose extension' type of Air Conditioner, the vast majority do not need any special instructions other than placing the exhaust hose out of the window - All you need to do is switch it on. If you are ducting through a suspended ceiling void then simply push the hose into the void. Some of the more powerful portable units comprise an internal condenser box which can be placed by an open window or through a doorway.

Do Portable Air Conditioners need to be filled with water?

 The units supplied by CW INSTANT COOL do not. However, be warned, many of the Air Conditioning units supplied by other companies do require frequent filling with water - (2/3 times daily ) which office staff find a nuisance.

How do I estimate my Portable Air Conditioning requirements?

Air conditioners are rated in BTu's (British Thermal Units) Working out your Btu requirements is simple. Using a calculator, follow these instructions:

1. Multiply the Length by the Breadth by the Height of the room to be air-conditioned. This will give you the cubic capacity of the room.
2. Multiply the cubic capacity of the room by 4. This will give you the Btu requirements of the room.
3. If you're taking your measurements in metres, all you do is multiply the cubic metres by 141.
   Please go to the Cool Calculator to perform this calculation.
