When you go to the electrical mall to buy air conditioner, the sales staff will ask you what horse number of air conditioner you buy, and what is the horse number? How do you know what you need? What is the relationship between the cooling area and the number of horses? Let's have a look.
How to choose the cooling area and the number of horses
Generally, when buying air conditioning, you should choose the number of air conditioning units according to the area of indoor air conditioning. The larger the indoor area, the larger the number of horses needed. The cooling capacity required per unit area is fixed. The larger the area is, the higher the cooling capacity is required. The higher the cooling capacity of air conditioner is, the higher the number of horses is. Generally speaking, we like to say the number of horses rather than the cooling capacity of the air conditioner.
The relationship between room area and cooling capacity
The selection of household air conditioning should be based on the area of the room, the height, orientation, the floor of the house, the insulation and other factors. Generally speaking, the cooling capacity is 130-180w per square meter. The heating capacity is about 10% more than the cooling capacity, and the heating capacity required per square meter is 150-200w. For a room of 20 square meters, it needs 2600w ~ 3600W cooling capacity air conditioner. Of course, it is better to choose an air conditioner close to 3600W. The air conditioner power is better than the actual one.
