How To Calculate Btu Hr For Air Conditioner. When it comes to air conditioners, the btu rating tells you how many btus per hour the machine can remove from the air. The chart below is a great starting point for sizing your ac.
Btu is a measure of energy, not power. Divide the watts per hour by 1,000 to find kwhs. On the right, the volume, v, divided by time gives us cubic feet per minute. Next, we also have to consider the number of people regularly in the room. When choosing an air conditioner, usually a 1 hp (horse power) equipment is able to remove 9,000 btu/hr of heat.
Other factors in determining the btu size would be the room's purpose.
On the right, the volume, v, divided by time gives us cubic feet per minute. So, to calculate btu/hr, use the following equation: Next, we also have to consider the number of people regularly in the room. Air conditioners are sized by the number of btus they put out. Well, when we talk about btus in relation to ac it refers to the amount of heat that the unit can remove from the air per hour. When we talk about air conditioner tonnage, a one ton unit is equal to.
