How to calculate the capacity of the air-conditioner in accordance with the room size

Choosing to buy an air conditioner with a capacity to suit the area of ​​the house, room volume is an issue that not all consumers can grasp, especially those who buy air conditioners for the first time. In this article, WebTech360 will share with you how to accumulate the capacity of the air-conditioner to match the area of ​​the room. 

Before we get into the main point, we will learn about how to calculate the basic area in 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

Calculate the capacity of the air conditioner 

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

We often hear the most often Btu / h Cooling Capacity, the section below will guide you on how to calculate the required cooling capacity for a 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 a 1 HP air conditioner (1 HP = 1 horse is equivalent to 9,000 BTU).

Details are as follows:

- Room size: 3 x 4 x 3m = 36 m3. Choose air conditioner 1 Hp 

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

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

- Rooms from over 30 m2 to 40 m2 (below 120 m3). Choose a 2.5 HP air conditioner 

Notes when choosing excess or insufficient capacity air conditioner

Notes when choosing excess or insufficient capacity air conditioner

When buying an air conditioner, choose a little extra capacity, it may cost a little more money, but in the long run it is more efficient than an air conditioner with a suitable capacity. This excess capacity air conditioner is quite powerful, cooled quickly, giving the machine more time to rest so its durability is extended and also less power consumption, because it only runs for 1 time. Shortly, the room reaches the cold temperature and automatically turns off while the machines with sufficient or insufficient capacity will have to run continuously to ensure the cold of the room.

Choose air conditioning for the household

Choose air conditioning for the household 

Household air-conditioners usually have a small capacity because they do not require too much cooling. However, for the living room, and the kitchen. You should add 0.5Hp

- Volume of about 40 m3 (block) = 1.0 Hp

- Volume of about 60 m3 (block) = 1.5 Hp

- Volume of about 80 m3 (block) = 2.0 Hp

Install air-conditioner for living room, office, restaurant

Installing air-conditioner for living room, office, restaurant ...

Installing room's air-conditioner The amount of cold air loss is relatively large, because there are many heat-generating devices such as: TVs, computers, fax machines ... and people who come in and out often, so now we will take the volume. for 35 ... 

- Volume of about 35 m3 (block) = 1.0 Hp

- Volume of about 55 m3 (block) = 1.5 Hp

- Volume of about 70 m3 (block) = 2.0 Hp

Hopefully the above article of WebTech360 will help you understand the concept of air conditioning capacity to install in accordance with the area used for your home.
