Many people face problems calculating Ac tonnage so today I’ll help you to calculate AC tonnage in few steps. As the summer season arrives the first image the person builds is of an air-conditioner that is AC. So if you are looking forward to know about AC, let me help you out with this.
Types of AC:
Basically seeing there are two types in Air-Conditioners:
- Window AC
- Centralized / Normalized AC
These AC types are differentiated on the basis of size and budget. So one should be clear while choosing an AC. So today we will help you with the calculation to buy A.C. for your personal room, hall or any other office purpose. There should be some factors you need to pay attention to like the heating capacity of your room for that you should consider the climatic condition, age of the house, the output of the furnace, total square feet and insulation of your furnace.

The cooling capacity of an A.C. system is measured on the basis of BTU which stands for British Thermal Units. A formula is needed for this to be calculated.
Basic Form Of Calculation For Tonnage:
First of all, you need is the size of the room. So firstly you start calculating the size of the room. The formulae for calculating the size of a room consists of measurements such as length, breadth, and height. You need to know the length, breadth, and height of the room. After knowing the measurements, apply the measurements in the formula which says:
“Area of the Room = Length*breadth*height”
After calculating the area of the room you can now calculate the BTU. Now you have to multiply the areas with a practical number that is 30 BTU. For example, if the room area is 180 square feet. Then BTU one requires will be 180*30 = 5400 BTU cooling capacity. It’s important to note that 12000 BTU is equal to one ton. So following this I provide a chart referring to different BTU required for different sizes of the room.
Chart For Your Room Size (BTU Needed)
|Room Area||BTU Needed|
|100 to 149||5,000 BTU/hr = 0.41 Ton|
|150 to 249||6,000 BTU/hr = 0.5 Ton|
|250 to 299||7,000 BTU/hr = 0.58 Ton|
|300 to 349||8,000 BTU/hr = 0.66 Ton|
|350 to 399||9,000 BTU/hr = 0.75 Ton|
|400 to 449||10,000 BTU/hr = 0.83 Ton|
|450 to 599||12,000 BTU/hr = 1 Ton|
|550 to 699||14,000 BTU/hr = 1.17 Ton|
|700 to 999||18,000 BTU/hr = 1.5 Ton|
|1,000 to 1,199||21,000 BTU/hr = 1.75 Ton|
|1,200 to 1,399||23,000 BTU/hr = 1.91 Ton|
|1,400 to 1,499||24,000 BTU/hr = 2 Ton|
|1,500 to 1,999||30,000 BTU/hr = 2.5 Ton|
|2,000 to 2,500||34,000 BTU/hr = 2.83 Ton|
So above you saw various kinds of BTU for different types of Room size. Now I will help you to know about the minimum amount of BTU required to heat a house according to the climatic change.
Amount of BTU required to heat a house on the basis of climatic conditions:
|House Age||Climate||BTU calculation|
The efficiency of an air conditioner can be measured on the basis of the Energy Efficiency Ratio (EER). Energy Efficiency Ratio is nothing but the ratio of BTU to the input power watt.
So the above information showed us how to calculate AC tonnage for your room. Sometimes calculation also varies according to your habitat or the place you live that is it depends upon the temperature of your habitat or surroundings, shade of your room, walls and materials made in the room, doors, and bricks of the room, type of the floor, wall and glass door thickness, air moisture level and then the square feet area of the room.

If the above-mentioned factors are of high quality and the construction of the room is done in perfect way than the room will have good coolant capacity when it is provided with AC.
Some common questions arise in people’s minds like which one is better window A.C. or wall-mounted built-in air conditioner. Wall-mounted built-in air conditioner is more efficient and best cooling units. As usually they are placed above the floor by 5-6 feet.
