How To Find Right Tonne Air Conditioner For Your Room?

In the chilly summer days when the temperature is too high and your body is sweating like hell, everybody wants a cold space where they can relax and have a cold drink.
But do you know how these things are still chilled in this hot summer or the restaurant where you are sitting, your office or your home?
Exactly, it's because of the Air-conditioning (A.C.) System.
Did you know that A.C. is not only used to cool your space, but it also used to warm your space.
The main aim of air conditioning system is to supply and maintain desirable internal atmospheric condition for human comfort, irrespective of external condition.
The factors which controls internal atmospheric conditions to produce desired human comfort conditions are temperature, humidity, purity and motion of air.
Now, when you know little about the Air-conditioning (A.C.) System it's time to jump on our topic "How To Find Right Tonne Air Conditioner For Your Room?", to do so get ready with a pen, paper and measurement. we are going to calculate the right tonne air-conditioner for your room?

We are going to calculate it with British Thermal Unit (B.T.U.).

First Step: Measure the size of your room.

Let's assume it's 20 feet wide and 30 feet long so,

20 x 30 = 600 square feet

It's 600 sq. feet area.

Second Step: Multiply the area with some constants(to find the required BTU to cool or heat your                            room).

If it's a bedroom, dining room etc. multiply the area with a constant 30.

600 x 30 = 18000 BTU's

 If it's a kitchen, multiply the area with a constant 40 (because of extra heat emitted during cooking).

600 x 40 = 24000 BTU's

 Third Step: Measure the height of your room(up to ceiling).

For every extra feet above 8 feet you have to add 1000 BTU's
Let's assume it's 10 feet high, so

18000 + (2 x 1000) = 20000 BTU's

"We humans are warm blooded and our body always radiate some heat to surrounding. That's the reason why on covering our body with a cold blanket after some time we feel warm. The blanket trapped the radiated heat in it's fur. Igloo house also work on same principle."

Fourth Step: Add number of people in room.

For every extra member above 2, you have to add 600 BTU's.
Let's say there are five members then,

20000 + (600*3) = 21800 BTU's

"If you have an adult pet say a dog then add another 600 Btu's for him."

Fifth Step: Now we are so close just convert the calculate Btu's in Refrigeration Tonne (RT).

1 RT = 12000 BTU's

Therefore,

21800 / 12000 = 1.8 RT

Its a ruff calculation there are some other factors too which affect:

1) The average temperature of your city.
2) Location and size of windows.
3) Number of appliances (T.V., Refrigerator, Bulb, Fan etc.)
4) Floor level i.e. on first floor, ground floor etc.

By accounting these factors we can say that an A.C. in between 2 - 2.5 Tonne is best for above room.
