What is Cooling Capacity - BTU'S of an Air Conditioner?
Cooling Capacity is the cooling power of a central air conditioner. It is
most commonly measured as the
BTUs per hour( A BTU is the quantity of heat
required to raise 1 pound of water by 1 degree Fahrenheit.) of heat that
the air conditioner can remove from the air. (You may also see cooling
capacity rated in tonnage.)
The only accurate way to determine the cooling capacity that you will need
in a residential or non-residential air conditioner is to have a heating and
cooling contractor perform a load calculation. This calculation will take into
account many factors about the building that you want to cool: its size,
number and direction of windows, amount of shade, amount of insulation, etc.
An air conditioner whose capacity is too small will not adequately cool
your residence or building. If the capacity is too large, it will cycle on and
off too often, decreasing efficiency and increasing your electric bill. In
addition, it will not maintain proper humidity levels, resulting in a less
comfortable environment.
