HOW CALCULATE HOW MANY TONS OF AC A ROOM NEEDED?

If you have a air conditioning, the tonnage is the most important factor. A "T" refers to the thermal capacity of one tonne of melting ice over one day. This means that a 1.5 tons of climate-device enough heat to the 1.5 tons of ice in a day can melt can be removed. So the larger the room, the more cooling performance of your air conditioning; therefore more tonnage. To find out which tonnage your room the best, please share the details of your room dimensions, view in direction, floor, the number of windows, etc.

Then how you calculate required tonnage for your room.?

The answer is very easy. On the ton AC required you should use the length, the width and the height of the room. If you multiply the figure (in meter) only to get all three in total.

So we can calculate its by volume formula Total = Length (m) x Breadth (m) x Height (m)

Now on the basis of given chart you can select required tonnage for your room.

Total	Ton AC Required
Less than 21	0.75
Between 21 and 23	0.75
25	0.75 to 1
28	1
31	1
34	1 to 1.5
37	1 to 1.5
41	1.5
48	1.5
56	1.5 to 2
64	2

There are also other factors that you need to consider for effective AC cooling.

§  The number of Windows in the room.

§  Application that produce heat such as TV, Desktop etc.

§  If the room gets too much sunlight.
