AC Tonnage
If you're thinking of buying an AC for, you must know about choosing the correct AC Tonnage. Today we'll discuss about ac tonnage calculation according to room size.
The smallest unit is 1.5 tons and largest unit is 5 tons.
Today electricity is very expensive and you don’t want to waste it on running a unit that is too big. On the other hand, getting a system that is too small will not keep your house cool, so while you will save money, you will not have the optimal temperature control and you'll end up regretting your decision of buying an AC.
We will also show you how to do a DIY estimate to figure out the central AC unit size you need for your house.
The two methods of calculating are:
- Area Method : To calculate, multiply the length and breadth of the room (in feet), take square-root of the answer and divide by 10. The resulting number will give the desired tonnage.
- Volume Method : Alternatively, multiply the length, breadth and height of a room (in feet). Divide the answer by 1000. This is the tonnage required.
For example:
- Using area method:
- Consider that I have a room with dimensions 15x10.
- Area=10*15=150 square feet.
- Divide by 10: 150/10=15.
- Take the square root: 1.247
Now it is clear that I must take a 1.2 tonne AC for my room.
- Using Volume Method :
- The room is 10 feet wide by 15 feet long and height is 20 feet (double height).
- That means 10×15 x 20 = 3000 cu.feet.
- (3000)/1000.
- We get 3 T.
- Choose an AC which is 3 Tonnes.
So basically for a room which is 3000 cu. feet (double height), we need to get 3 ton AC.
For your convenience I've made a table:
- Less than 750 cubic feet 0.75 Tons.
- Between 750 and 800 cubic feet 0.75 Tons.
- Between 800 and 900 cubic feet 0.75 Tons.
- Between 900 and 1000 cubic feet 1 Ton.
- Between 1000 and 1200 cubic feet 1 Ton.
- Between 1200 and 1500 cubic feet 1.5 Ton.
- Between 1500 and 2000 cubic feet 1.5 Ton.
- 2000 to 2300 cubic feet 2 Ton.
