When buying air conditioning

Three principles for choosing air conditioners:

1. Because the heating effect of air conditioning 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 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 use of air conditioning room conditions and regional climate differences, as well as plans for extreme weather, buy air-conditioning should buy big or not buy small.

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 a room of 20 square meters, the applicable area of ​​1.5 air conditioners for a certain brand is 16 to 20 square meters in winter, and the applicable area for 2 air conditioners is 22 to 26 square meters in winter. The customer should purchase 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).

Avoid two misunderstandings. 1. Air conditioning is the most power-consuming household appliance. Avoid misunderstandings that cost less to buy. The inefficient consumption of cheap goods after use will cause you to actually spend more. When you spend more money to buy electricity at the time of purchase, the savings in electricity costs in the future will be much greater than when you buy them.

2. There are a dozen kinds of air conditioners for Chinese brand names and well-known brands, and the quality is good. It is necessary to avoid the online shopping for good brand misunderstandings. In this way, a dozen brands of recommendations will be obtained, which will make you lose your mind and be at a loss.

He should spend time on market research. Suning's and Gome's, local stores have to go around, communicate with the various guides of the brand Purchasing, and more to see more and more to listen to, and more points air-conditioning propaganda color pages, do not rush to pay the money (before you take the initiative, after delivery You are passive. Return to the home and think calmly, go to the falsified truth, analyze and compare, combine your own room conditions, economic budget, individual preferences, and make rational purchase decisions.
