Window AC / March 17, 2018 / Aubrette Dumoulin.
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.
When purchasing a window air conditioner it is very important to purchase one with the proper cooling capacity. An air conditioner that is not properly sized will not work as efficiently as one that is sized properly. This is one of the most common mistakes made when selecting air conditioners. Use an air conditioner size calculator to select the proper sized unit for the room you want to cool. Undersized air conditioners will run continuously and not cool the space adequately and an oversized unit will cycle on and off too often. This increases equipment wear and can actually cause fuses to fail.
Why are window air conditioners so loud? Well the reason is simple: because the entire air conditioner - the compressor the condenser and the fans - are all located in one single unit. By contrast with a split ac and a central air conditioner the compressor and condenser are installed outside of your home. That means that in those units the loudest parts arent in your home. With a window unit however the noisiest parts of the unit are inside your home. This can be a minor annoyance. It may mean that you have to turn up the volume on the tv to hear it. But it can also mean sleepless nights if your window air conditioner in your bedroom is deafening.
This will help you determine the amount of BTU s necessary to cool your room adequately. For example an 8000 BTU unit will cool a room up to about 350 square feet. Another thing to consider when buying a window unit is any special features that come with the unit. In particular most window units include louvers that let you direct airflow programmable timers so that you can set the unit to turn off or on when you wish and energy efficient features like multiple fan speeds. Many units also come standard with a remote control so that you can adjust the temperature from across the room.
