Secret air conditioning buy three **

Many of my friends are rushing to start using 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 choosing air conditioners, we also need to follow certain principles. We don't necessarily have to say that the frequency conversion and fixed frequency are good, but we must start with the purchase and follow the basic premise of purchase. Under the premise of buying the right air conditioning products.

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

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

Of course, if you purchase a single-cooled air-conditioner, it depends on the (summer) application area (the same below).

2. Due to the difference in the conditions of the air-conditioned rooms and the climate in the area, and plans for extreme weather, buying air-conditioning should be a big buy.

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

3. Air-conditioning energy efficiency ratio = cooling capacity, cooling power.

Therefore, the same number of air conditioners, buy energy efficiency ratio than high energy efficiency than low energy efficiency.

For example, when a customer purchases air-conditioner for his/her 20-square-meter room, the applicable area of ​​1.5 air conditioners for a certain brand is 16~20 square meters in winter, and the applicable area for 2 air conditioners is 22~26 square meters in winter. The customer should buy 2 Air conditioning. Then look at the brand with two air conditioners, there are several, choose which high energy efficiency (for example, there are two kinds, an energy efficiency ratio of 3.2, another energy efficiency ratio of 2.6, buy 3.2).
