Air Conditioner British Thermal Unit Calculator calculator can be used to determine the cooling capacity required for an air conditioner based on room size, insulation, and desired temperature change.
Learn how to use the Air Conditioner British Thermal Unit Calculator calculator and its working principles
The calculator uses the following formula to determine the required BTU:
BTU = 1.05 * (Area * Height) * (Temperature Change) * (Insulation Factor)
Where:
For a room with an area of 1,500 sq ft, a ceiling height of 8 ft, an insulation rating of 5, and a desired temperature change of 15°F, the calculation would be:
BTU = 1.05 * (1500 * 8) * 15 * (11 - 5) = 1.05 * 12000 * 15 * 6 = 113400 BTU
This means you would need an air conditioner with a cooling capacity of at least 113,400 BTU to cool this room.
