How big is the air conditioner to buy for a living room of more than 40 square meters

At least 3P.

Generally, 1 hp air conditioner is suitable for an area of 10 15 square meters, 10 19 square meters for horse, 16 26 square meters for horse, 15 30 square meters for horse, 2 horsepower for 20 37 square meters, and 3 horsepower for 30 58 square meters.

Anyone who buys an air conditioner knows that the price is different depending on the number of air conditioners. The number of air conditioners originally refers to the input power, including the press, fan motor and electronic control part, due to the differences in the specific system and electronic control design of different brands, the output cooling capacity is different, so the cooling capacity is calculated by the output power.

Generally speaking, the cooling capacity of 1 hp is 2000 kcal, which should be multiplied into SI units, so the refrigeration capacity of 1 hp is 2000 kcal 1 162 2324 watts, where watts (w) represent the cooling capacity, then 1 5 hp should be 2000 kcal 1 5 1 162 3486 (w), and so on. Based on this situation, the number of horsepower and cooling capacity of the air conditioner can be roughly determined. In general, 2200 (W) 2600 (W) can be called 1 horse, 4500 (W) 5100 (W) can be called two horses, and 3200 (W) 3600 (W) can be called 1 5 horsepower.

After the cooling capacity is determined, you can estimate the cooling capacity according to the actual situation of your household and choose the appropriate air conditioner.

Household appliances need to consume a larger part of the refrigeration capacity, TV, lights, refrigerators, etc. per watt (w) power to consume 1 (w), the direction of doors and windows should also consume a certain amount of refrigeration, east window 150W m2, west window 280W m2, south window 180W m2, north window 100W m2, such as the roof and west sun can consider appropriately increasing the cooling capacity.

The applicable area of air conditioning is 10 15 square meters;

2. Horsepower is applicable to 10 19 square meters;

3. Horsepower is applicable to 16 26 square meters;

4. Horsepower is applicable to 15 30 square meters;

5. Two horses are suitable for 20 37 square meters;

Suitable for 30 58 square meters.

The definition of air conditioner horsepower is as follows:
