How To Find The Proper Aircon Capacity For Your Room Size

Before going into the main topic, we will learn about how to calculate the basic area according to square or rectangular plan. Before preparing to install the air conditioner, we should measure the height from the floor to the ceiling.

– Area S = Length 4m x Width 3m = 12 m2

– Volume V = S x Height 3m = 12 m2 x 3m = 36m3

Calculating the capacity of the air conditioner 

1 HP (electrical capacity, compressor capacity) = 750 W (electrical capacity) = 9000 BTU/h (refrigeration capacity). Cooling capacity = W.

We often see or hear the most is Cooling capacity Btu/h, the section below will show you how to calculate the required cooling capacity for the room in this unit Btu/h. 

We can apply the formula: 1 m2 x 600 BTU. In which, BTU is the British thermal unit, used to measure the capacity of heating or cooling equipment. 

For example, a room with an area of ​​​​15m2 you will calculate: 15 m2 x 600 BTU = 9,000 BTU equivalent to an air conditioner with a capacity of 1 HP (1 HP = 1 horse equivalent to 9,000 BTU).

Details are as follows:

– Room size: 3 x 4 x 3m = 36 m3. Choose 1 HP air conditioner 

– Room size: 4 x 5 x 3m = 60 m3. Choose 1.5 Hp air conditioner

– Room size: 4 x 6 x 3.5m = 84 m3. Choose 2 Hp air conditioner

– Rooms over 30 m2 to 40 m2 (under 120 m3). Choose air conditioner 2.5 HP 

Notes when choosing an air conditioner with excess or lack of capacity

When buying an air conditioner, you should choose a little excess capacity, it may cost a little more money, but in the long run it is more effective than an air conditioner with a suitable capacity. The air conditioner with this residual capacity is quite powerful, cools quickly, helps the machine have more time to rest, so its durability is prolonged and also less power consumption, because it only runs for 1 time. In short, the room reaches the coldness and automatically turns off while the machines with sufficient or insufficient capacity will have to run continuously to ensure the coldness of the room.

Air conditioners for a household

Household air conditioners usually have a small capacity because it does not need to cool too much. However, for the living room, and the kitchen. You should add 0.5Hp

– Volume 40 m3 (cubic) = 1.0 HP

– Volume of about 60 m3 (cubic) = 1.5 HP

– Volume of about 80 m3 (cubic) = 2.0 Hp

Air conditioners for living rooms, offices, restaurants

Installation of air conditioners for living rooms, offices, restaurants…

Install air-conditioner for the room The amount of cold air loss is relatively large, because there are many devices that give off heat such as: TVs, computers, fax machines… and people come in and out often, so this time we will divide the volume. for 35… 

– Volume of about 35 m3 (cubic) = 1.0 HP

– Volume of about 55 m3 (cubic) = 1.5 HP

– Volume of about 70 m3 (cubic) = 2.0 Hp

Hopefully, the above article will help you better understand the concept of air conditioning capacity to install in accordance with the area used for your family.
