The cooling of a room also depends on other factors other
than ton like, insulation, number of windows, sunlight, heat producing
appliances in the room like TV, computer etc.
A simple calculation is as
follows
Multiply the length, breadth and height of
the room (take units as feet). Then divide this by 1000 to get the ton capacity
Example if the room’s size is 10 feet by 10 feet by 10
feet
So 10 X 10 X 10 comes out to 1000, divide this by 1000
the answer comes to 1. So your as tonnage requirement is one ton.
Another example room size 12 feet by 12 feet by 9 feet.
The multiplication comes out to be 1290. Dividing this by 1000 leads to 1.2. so
tonnage requirement is 1.2 ton. If there is direct sunlight in the room
and /or the air conditioner is exposed to sun, or you stay on the top
floor where roof heats up, go for 1.5 tom AC otherwise go for 1 ton AC as air
conditioners are available in 0.75 ton. 1 ton and 2 ton and above capacity only
