Before choosing to buy an air conditioner for your home or office, your agency should learn how to calculate the capacity of the air conditioner in accordance with the space and use needs. Such careful calculation not only gives the most optimal cooling efficiency but also saves significant electricity costs. Please refer to the following article to get the most appropriate choice before installing the air conditioner!
Table of conventions for calculating air conditioning capacity in accordance with the area, volume and height of the room
1. Why should you install the right capacity air conditioner?
Installing the right air conditioner not only brings good cooling efficiency but also saves you monthly electricity costs.
When the air conditioner capacity is too small compared to the room area, the machine must operate continuously, causing overload, consuming a lot of power, affecting the durability of the machine.
If you install an air conditioner with a large capacity in a small room, it will waste energy and cost you money to buy a large capacity model.
2. How to choose the right air conditioner capacity for the room area
Capacity calculation formula based on room area: 1 m2 x 600 BTU.
For example: The room has dimensions of 5m (length) x 3m (width), the calculation of capacity is as follows:
(5 x 3) x 600 = 9000 BTUs. Therefore, you should choose an air conditioner with a capacity of 9000 BTU.
Basic parameters when choosing to buy an air conditioner suitable for room area:
Rooms with an area of less than 15 m2: Choose an air conditioner with a capacity of 9,000 BTU
Rooms with an area of 15 m2 – 20 m2: Choose an air conditioner with a capacity of 12,000 BTU
Room with an area of 20 m2 – 30 m2: Choose an air conditioner with a capacity of 18,000 BTU.
Room with an area of 30 m2 – 40 m2: Choose an air conditioner with a capacity of 24,000 BTU
3. How to choose air conditioner capacity by volume, room height
This calculation will meet more accuracy than the calculation by area. This calculation should be applied to cases of houses with high ceilings, attic rooms from the top down…
Capacity needed for the room = Room volume * 200 BTU (equivalent to 200 BTU/m3)
Room volume = room area x height (15m2 x 3m = 45m3)
For example: A room with a volume of 45 m3 you will calculate: 45 m3 x 200 BTU = 9000 BTU => should choose an air conditioner with a capacity of 9000 BTU to meet the cooling needs.
4. Other points to note before buying an air conditioner
Material of the walls and roof, is it hot, ventilation in the room (many furniture, electronics)
The number of people in the room: Coffee shop, restaurant, living room, bedroom, etc. will have a different number of people who usually stay, so it also affects how to choose different machine capacity.
The flow of solar radiation affects a room such as a room with many windows and glass doors.
