What is air conditioner ton
Ton as the name suggests is equivalent to 1000 kg. How is this related to air conditioner? Actually room air conditioners were derived from the technology used to refrigerate ice or to convert water to ice in earlier times. To relate ice and cooling capacity a formula is derived which says the amount of energy required per hour to make one ton of ice in twenty-four hours.
So one ton is equal to 12000 BTU.
Cooling capacity of an air conditioner is measured in tons so one ton AC provides 12000 BTU in one hour.
How much ton AC is suitable for your room
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
