Window AC / September 1, 2018 / Babette Arsenault
A window air conditioner is supposed to stay in place. This is different from a portable unit which rests on casters so that you can roll it from room to room. In most cases however a window unit will provide better cooling at a lower price that what a portable air conditioner can offer. Moreover you can install a window unit in each room if necessary. By many estimates having two or three window units is still cheaper than investing in a central system. When you are choosing a window air conditioner it is a smart idea to take measurements of the room you plan to cool.
Air conditioners are old-timers among climatic equipment which provide comfortable conditions for living. The first window air conditioning system was invented in America in 1930s. Such devices became widespread at once due to their simple design low price and rather high power thus making the cooling of individual rooms possible. Buy your conditioner as per the appropriate BTU. It is a measurement of energy abbreviated as BTU which stands for British Thermal Unit. For this purpose you will be required to find the correct BTU of your room. BTU is proportional to the amount of heat a window conditioner will remove from a room.
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.
