How to Choose AC Tonnage
In laymen term, AC Tonnage is simply the cooling capacity or the cooling output of the air-conditioner. The calculation is quite simple. One ton is equivalent to 12,000 BTU. If the Air-condition is 24,000 BTU then it is 2 ton.
What is BTU?
BTU is the abbreviation of British Thermal Unit, one BTU is the amount of heat required to heat one pound of water. One pound of water is equivalent to two teacups. It is calculated through Fahrenheit. British Thermal Unit for Air-conditioner calculates the number of BTUs every hour the AC can remove from the air.
AC Tonnage Calculator
With Tonnage calculator one can gauge the (unit) ton of AC required in your residence or house. It is calculated by taking the below parameters into consideration:
- City you live in
- Room dimensions in ft
- Area of windows in sq.ft
- Window direction (west facing or east facing) to gauge the sunlight
- Apartment or House
- Daily usage
When selecting an AC one should consider the above parameters. After calculation, if your room requires 1.5 ton then the automatic selection should be 1.5 tons.
Note: You can use the above AC Tonnage Calculator to calculate the amount of the AC Ton required for your room. The calculation is applicable to all brands like LG, Samsung, Daikin, Hitachi, Blue Star, O General, Mitsubishi, Voltas, Carrier, Panasonic, Godrej, and Onida. If your city is not present in the above calc, choose the nearest one or any other city where the climatic conditions are similar.
How to Select Air-conditioner Tonnage
Let us begin with BTUs. A higher BTU many not necessarily mean that the AC is of great quality. You cannot gauge the AC by the number of BTUs. Higher BTU can cool the room quickly and then it cycles off in order to maintain the ideal room temperature.
This recurring on and off of cycling would overload the compressor, and if this cycle continues, it might shorten the lifespan of AC. This issue is quite common in Portable ACs. In Portable AC’s BTU is very important. One should look for the right AC that can maintain ideal room temperature.
Square footage is a vital parameter when choosing an AC. The BTU’s requirement is directly proportional to the room size. If the room size is more the BTU requirement will be more.
There are certain factors that one should consider when selecting AC with right Ton/BTU. This could be a common factor in apartments, where there is a possibility that the apartment on the 6th floor could be warmer than the 3rd or the ground floor.
There is a possibility in a room with a large window facing west, which might receive direct sunlight. It is highly recommended to go for an AC with 10% more BTU.
The possibility of overcooling is also on the cards. There might be areas where there is not much of sunlight or there is enough cover around. There could be a huge skyscraper or a big banyan tree covering a long area, almost stopping the sunlight. In such a situation, one can opt for an AC with 10% less BTU.
The other variable factors are the number of people living in the room. If the numbers of people are more for a specific period, it could very well affect the BTU. Hence, this could also increase the BTU.
In conclusion, it is better to look into various factors and most important do some research and basic calculation. To make things easier, you can use the above AC Tonnage Calculator to calculate the ton required for your room.
