Strictly speaking, there is no very uniform standard for the calculation between the cooling capacity and the area of ​​an water air cooler, because it depends on the environment in which the air cooler is used. In other words, it needs a little more cooling capacity, and ordinary rooms are different from the living room. Also, for example, a room with western exposure in tropical areas needs to increase the cooling capacity relatively.

At present, the nominal cooling capacity of water air cooler on the market is very inconsistent and standardized. Strictly speaking, the output cooling capacity of an water air cooler should be expressed in W (watts), and horses are often used in the market to describe the cooling capacity of an water air cooler. The conversion relationship between the two is: the cooling capacity of 1 hp is about 2000 kcal, which should be multiplied by 1.162 when converted into international unit watts. In this way, the cooling capacity of 1 hp should be 2000 kcal × 1.162=2324W. The W (watt) here means the cooling capacity, and the cooling capacity of 1.5 hp should be 2000 kcal × 1.5 × 1.162 = 2486W.

Under normal circumstances, the cooling capacity required per square meter for an ordinary family room is 115-145W, and the cooling capacity required per square meter for the living room and dining room is 145-175W.

For example, a family living room has an area of ​​15 square meters. If the required cooling capacity per square meter is 160W, the required cooling capacity of the water air cooler is: 160W×15=2400W.

In this way, the XK-20S wall-mounted water air cooler with 2500W cooling capacity can be purchased according to the required 2400W cooling capacity.

The so-called energy efficiency ratio, also known as the coefficient of performance, is the ratio of the nominal cooling capacity of an water air cooler to its power consumption. Usually, the energy efficiency ratio of the water air cooler is close to 3 or greater than 3, and it belongs to the energy-saving water air cooler.

For example, the cooling capacity of one water air cooler is 2000W and the rated power consumption is 640W, and the cooling capacity of another water air cooler is 2500W and the rated power consumption is 970W. The energy efficiency ratios of the two air conditioners are respectively: the energy efficiency ratio of the first water air cooler: 2000W/640W=3.125, and the energy efficiency ratio of the second water air cooler: 2500W/970W=2.58. In this way, through the comparison of the energy efficiency ratio of the two water air cooler, it can be seen that the first air conditioner is an energy-saving water air cooler. The number of water air cooler refers to the input power of the water air cooler, which is indirectly related to the usable area, and directly related to the usable area is the cooling capacity. In my country, the cooling capacity of one water air cooler is generally about 2300W. There are some differences in quantity.

water air cooler design is generally designed according to cubic meters of space, that is, one cubic meter has a cooling capacity of 50W, and consumers can calculate the applicable area of ​​ water air cooler according to the height of their own houses.

For example: a one-horse hanger, the cooling capacity is 2300W

Its applicable volume is 2300/50=46 cubic meters

If the room height is 3 meters, the applicable area is 46/3=15.3 square meters.

When choosing, the orientation of the house and whether it is on the top floor should also be considered. The cooling capacity should be appropriately increased on the top floor. It is recommended to choose 2500W.
