Air Conditioning: calculating the cooling powerAir conditioners used to be a luxury. They were the domain of the well-to-dos, the better-offs, people who could easily afford such an outlay and for whom the price of having deliciously cool rooms in which the air remained refreshingly crisp despite the soaring, sizzling summer temperatures outside was also a matter of prestige and could therefore not be high enough.

But that was yesteryear. Many people have discovered for themselves that air conditioners are no longer a luxury as far as the price tag is concerned. And they have also come to realise that in many cases they are an absolute necessity. That’s because they not only monitor and control the indoor climate and ensure that it is kept at levels that have an obvious and positive effect on your health, they also enhance your feeling of well-being and protect both your prized possessions and your property.

There’s a variety of different types of air conditioners to choose from. There are slim, compact models and there are more generously-sized ones. The size depends mainly on the power of the unit and the volume and the type of the room or rooms which you would like to keep the temperature – and equally importantly the relative humidity – at the constant levels you require.

The two main types of air conditioner we differentiate between are the split models and the monoblocs. The type you select depends on your individual requirements – and the location where you wish to install your air conditioner.

Air conditioners that consist of two units – one which is placed on the inside of the room and one which is placed on the outside of the building – are called split models. Such air conditioners are, as a rule, more powerful and more efficient than other models, because they not only cool the air inside the room, they also transport the warm air which is generated by the unit itself outside the room and out of the building. The downside, if you will, is that because they are attached to each other by a flexible air discharge hose which is fed through a hole in the wall between the two units they are less mobile.

Monobloc air conditioners comprise a single unit, hence the term mono. Such models are specially designed for users who are looking for a relatively simple means of maintaining a clean, healthy and cool indoor climate and for whom the added mobility is a valuable feature. These models are light and easy to transport and do not require any prior changes being made to the building. All you need to do is pop the end of the hose out of a tilted window and switch on your unit.

OK, I’ve got that. But what cooling performance? How do I know how much cooling performance I need?

As always, the answer is easy when you know how. And as we have been in the business of providing air conditioning solutions to both private households and commercial enterprises for nearly 20 years now, we do know how. That’s because we have both the know-how and the experience to help you find the right air conditioner for your own individual requirements.

If the rooms are insulated, then you can count on needing 40 watts of power per cubic metre. Multiply the volume of the room you are planning on installing your unit in with this number and you have your guideline on how much performance your dehumidifier will have to bring in a single hour. Simples! You will need a little over 30% more power, ie. 55 watts in all to condition the air in poorly insulated rooms or portable cabin offices and 2½ times as much, ie. 95 W/m³ to treat the air in a tent or pavilion.

But beware! You might end up getting very annoyed with yourself if you buy a model that is not powerful enough to cool and clean the air in your office or room by choosing not to err on the side of caution. It’s always a good idea to doublecheck your calculations and to allow for other factors like exposure to sunlight, the heat that radiates from other people’s bodies or electrical appliances, like computers for example. So better safe, than sorry!

Go here to our online-capacity calculator to work out the capacity you need. It really is quite simple. Honestly!
