What do you need to know?
So, how do you calculate what size of air conditioner you need?
Providing you do not have south/west facing window(s) or excessive heat generating items in the room, the minimum cooling duty required can generally be calculated by multiplying the room’s cubic metre area by .04 as in the following example:
Room Size: – 6mtrs x 4.5mtrs x 3mtrs = 81 cubic metres.
Calculation: – 81 cubic metres x .04 = estimated minimum cooling requirement of 3.24kW
