In general, the required cooling capacity and heating capacity of a room can be calculated according to the following parameters. The cooling capacity is equal to the room area × 140W to180w; Heating room area × 180W to 240W. Doors and windows also consume some energy.
Extended data:
The output cooling capacity (heat) of the air conditioner to be purchased should correspond to the use area. Due to the differences in room conditions and regional climate, as well as the plan for extreme weather, it is necessary to buy large air conditioners instead of small air conditioners.
There are many factors that affect the heating effect of air conditioning, the most important of which are floor, sunshine, west window and apartment type. So how to accurately calculate the air conditioning power required by the room?
Firstly, the required cooling capacity per square meter is set as150 w;
If the top floor and the west sun account for one of them, it will be calculated as 200W per square meter;
If there is a west window or a top floor with the west sun, at least 250 W； per square meter;
There are both west windows and top floors, with at least 300 W； per square meter;
Only more can not be less, otherwise the constant speed machine will not stop or the frequency converter will run at full speed until the protection is started, resulting in the inability to adjust the indoor air temperature; Please refer to the table below for regional selection.
The room area is suitable for air conditioning (refrigeration)
/kloc-23 machines under 0/0m2 (one smaller)
10M2- 14M2？ 26 machines (one larger)
14M2- 18M2？ 32 machines (one and a half smaller)
16㎡-20㎡？ 35 machines (plus one and a half horses)
20㎡-32㎡？ 50 machines (plus two)
30㎡-45㎡？ 6 1 machine (two and a half horses)
45㎡-55㎡？ 75 machines (Big Three)
