When installing air conditioning , there are two important numbers you must focus on. The first is BTU, or British Thermal Unit. This is a measurement of how cold the air conditioner can make a room.
The second is CFM , or Cubic Feet per Minute. To calculate room air changes, measure the supply airflow into a room, multiply the CFM times minutes per hour. Then divide by the volume of the room in cubic feet: In plain English, we’re changing CFM into Cubic Feet per Hour (CFH). Then we calculate the volume of the room by multiplying the room height times the width times the length.
