A shop of about 20 square meters wants to buy an air conditioner, and the door will be opened and closed frequently, and it is difficult to decide whether the fixed frequency or frequency conversion is appropriate, and how many horses to buy. 20 flats is enough, so don't buy too many horses. My room is 1 ma, which soon gets cold, and it is still a room of 25 square meters. First of all, you did it for the store.

It will take a long time. It is best to choose frequency conversion to save electricity. Don't underestimate savings. It will save a lot over time. The cheapest is Kelon's. If the store prepares itself, it is an ideal choice to buy a Gree. Several grees in our factory have been used for several years and are still so great! Choosing frequency conversion can't be wrong. If you want to get good grades, get on 1.5.

Let's see what others say.
