Window AC / September 10, 2018 / Francoise Salmons
The main aspect in the choice of window air conditioner is its cool air performance. You can approximate the required power at the rate of 1 kW per 10 sq.m. with a ceiling height of 2.8 - 3 meters; for household models the characteristic is: from 1.5 - 2 to 6.5 - 8.5 kW. If there is a large glass area in the room windows face south or there are other additional heat inputs one should better buy a model with a power reserve of 15-20%. Another important factor in choosing window air conditioner is room functionality. For example air conditioner installed in the kitchen must be of high performance to provide optimal heat control. Air conditioning unit for bedrooms should have low noise characteristics.
Window air conditioners came to the market as a solution for people who couldnt afford or did not want central air conditioning. Because central air conditioning can be quite expensive and because many people live in small apartments central air is not for everyone. This led to the advent of window air conditioners. Window air conditioners have a hot coil and a chilled coil along with two fans. The fans blow air over these coils and they in turn suck away the heat and humidity from the room into the outside area providing clean cool air. The capacity of an air conditioner is measured in BTUs. So the size of the air conditioner plays a vital role in determining its cooling capacity.
If you choose to use a window air conditioner than you should also look for a place that it can be secured and placed in a room that you will not be sleeping in. As you can tell by now I am not a big fan of window air conditioners. They do have a place for some people. However you do need to be aware of the problems that you may encounter with them. The low initial cost can be offset by the fact that they typically do not last as long as a central air conditioner. Central air conditioning will last much longer be quieter during operation be more efficient be more secure but the initial cost will be higher.
