It is not rigorous to select air conditioners based on the number of horses. The correct way is to look at this parameter!

Summer is coming soon, and it’s the season when air conditioners are selling well. When I go to the store to buy air conditioners, the first question I face is "how many horses to buy". What does the number of air conditioners mean? Is the number of horses chosen for air conditioners scientifically? okmarts.com teaches you the correct posture to buy air conditioners!

What is the number of air conditioners

The number of air conditioners originally refers to the input power of the air conditioner. 1 horse (horsepower) = 735W (watts). In the past, the verbal call in Japan called an air conditioner with an input power of 735W as 1 horse air conditioner, and an air conditioner with an input power of 1470W as 2 Air conditioner, but because the input power of the air conditioner may not be exactly the whole horse, for example, 1400W or 1600W are called small 2 horses and large 2 horses respectively, and between 1 and 2 horses, 1.5 horses and so on.

　　 It can be seen that the horsepower of the air conditioner refers to the input power of the air conditioner. At present, the "hp" mentioned in the sales of air conditioners is the cooling capacity estimated based on the power of the air conditioner. We all know that when purchasing an air conditioner, it is more important to refer to the cooling capacity of the air conditioner. What is the relationship between the horsepower and the cooling capacity?

　　Usually, we judge the cooling capacity of an air conditioner based on the output power of the air conditioner. Under ideal conditions, the output power of 1 horse is about 2300~2500 watts. The ratio of the output power of the air conditioner to the input power can reflect the energy efficiency ratio of this air conditioner. The higher the energy efficiency ratio, the lower the power consumption. The current national standard divides the energy efficiency ratio of air conditioners into 1, 2, and 3 levels, of which the first level is the most energy-efficient.

　　 The reality is that air conditioners with the same input power may not produce the same cooling capacity due to different energy efficiency ratios. Therefore, it is difficult to determine the cooling capacity of an air conditioner by input power (that is, the number of horses). Because it is possible that your 3 horsepower can only produce 2 horsepower for cooling.

　　 Now, the national standard uses the hourly cooling capacity as the standard for air conditioning capacity.

　　How to choose the cooling capacity

　　Under normal circumstances, the cooling capacity required per square meter for an ordinary family bedroom is 115~145W, and the cooling capacity required per square meter for the living room and dining room is 145~175W. Generally, the median value is acceptable, such as 130 for the bedroom and 160 for the living room. Based on this, we can calculate the required air conditioning cooling capacity in the home based on the area. For example, if the living room area of ​​a family is 15 square meters, if the required cooling capacity per square meter is 160W, the required air conditioning cooling capacity is: 160W×15=2400W.

　　 The cooling capacity is marked on the nameplate of the air conditioner

　　The national standard stipulates that the size of the room air conditioner is marked according to the cooling capacity parameter. At present, the cooling capacity is clearly marked on the model of the air conditioner. For an air conditioner with model KFR-35GW/WDAA3@, the number "35" means that the cooling capacity of this air conditioner is 3500W, which can be referred to as "35". type". 25 units and 35 units are an abbreviation of refrigeration capacity. For example, KFR25W is abbreviated as 25 units; KFR5Gw is referred to as 35 units. Among them, 25 units indicate a cooling capacity of 2500W, 35 units indicate a cooling capacity of 3500W, and so on .

　　 Here are some choices of daily use area and air conditioner model.

to sum up

It is not scientific to choose an air conditioner based on the number of horses alone. On the whole, it is a more rigorous method to choose an air conditioner based on the cooling capacity. The required cooling capacity is obtained based on the area of ​​the home, and then the corresponding model is purchased. You can choose a machine with a higher energy efficiency ratio, so that you can get the most suitable air conditioner.
