Encountering hidden rules, revealing the three rules of air conditioning purchase

Summer is the peak season for air-conditioning purchases. Many friends have started to use a combination of air-conditioning products before the summer, but when faced with a variety of products on the market, they are often confused and do not know how to start.

In fact, when purchasing air conditioners, we also need to follow certain principles. It is not necessary to say that the inverter and the fixed frequency are good. Instead, we must start with the purchase premise and follow the basic premise of the purchase. Under the premise, choose the air conditioner that suits you.

1. Since the heating effect of the air conditioner is lower than the cooling effect (the applicable area in winter is smaller than the applicable area in summer), the air conditioning should be based on the heating index.

Therefore, the purchase of air conditioners is based on the applicable area in winter.

Of course, if you purchase a single cold air conditioner, it is based on the (summer) applicable area (the same below).

2. Due to the difference in the condition of the air-conditioned rooms and the regional climate, as well as the plan for extreme weather, buy air conditioners should buy big or not.

Therefore, it is necessary to purchase air conditioners based on the applicable area in winter and the lower limit of the applicable area in winter.

3. Energy efficiency ratio of air conditioner = cooling capacity ÷ cooling power.

Therefore, the same number of air conditioners, energy efficiency and power saving are higher than the energy efficiency ratio.

For example, when a customer purchases air conditioners for a room of 20 square meters, the winter applicable area of ​​a brand of 1.5 air conditioners is 16-20 square meters, and the winter applicable area of ​​2 air conditioners is 22-26 square meters. The customer should purchase 2 Air conditioning. Then look at the brand of the same two air conditioners, there are several energy-efficient ratios (such as 2, one energy efficiency ratio of 3.2, another energy efficiency ratio of 2.6, the purchase of 3.2).
