To calculate the cooling capacity of an air conditioner, many people often apply the formula 1m 2 x 600BTU . Accordingly, you can calculate the following:
If the room has an area of 15m2, the cooling capacity will be: 15m 2 x 600BTU = 9000BTU
Cooling capacity | 9,000BTU | 12,000BTU | 18,000BTU | 24,000BTU |
Cool room, no direct sunlight | 26m 2 | 35m 2 | 50m 2 | 60m 2 |
Hot room with direct sunlight | 16m 2 | 21m 2 | 35m 2 | 42m 2 |
Choose the capacity of the air conditioner for the room with sunlight
In addition, the choice of the capacity of the air conditioner also depends on the number of people often in the room because human body temperature will reduce the coldness, sunlight coverage, room insulation, location. and the size of the window,. These are factors that can reduce the cold. In addition, a room with many electrical appliances also emits a significant amount of heat.

If you choose an air conditioner with enough capacity, you will ensure that the investment is appropriate, the amount of electricity consumed is also appropriate.
Never choose an air conditioner that lacks capacity compared to the usable area of the room. The temperature is not cold enough will force the air conditioner to work continuously, leading to power loss, overheating and the durability of the machine will also decrease without achieving the necessary cold.
When buying an air conditioner, you should choose a capacity slightly larger than your need. The initial investment may be more than choosing the right machine, but the benefit is that the machine is strong, the time to reach the cold temperature is faster and when the machine reaches the cold enough temperature, it will automatically stop working. With a machine with excess capacity compared to demand, the machine will have a lot of "break" time, helping to prolong the machine's durability.
A large capacity air conditioner does not mean it will consume more electricity than a small capacity air conditioner. It only differs in price, you will be wasted when not using its full capacity.
