The most common rule of thumb is to use 500 square feet per ton to determine the size of air conditioner needed. Or 400 or 600 or some other number in that general vicinity. In my article, I showed a graph of air conditioner sizes, given in square feet per ton, for 40 homes that we did load calculations for. The … The sensible heat ratio is useful in finding G, the moisture content of air, at different conditions using a psychrometric chart. 5. Psychrometric Chart A psychrometric chart is a graphical representation of the properties of moist air and is a useful tool in air conditioning calculations. This chart can be
