During the summer vacation, the temperature often rises to 37 or 38 degrees. When it is really hot, do you turn on the air-conditioner? But do you know how to choose the air-conditioner to cool it with the least amount of electricity? How to convert the "tons" of air-conditioner?👉

Multiply the number of pings in the room by 0.15, which is the metric tons of the air conditioner! In other words, if the number of living rooms is 10 pings, choose an air conditioner of 10*0.15=1.5 metric tons. If it is a complex space, a room with the west-facing wall or a large window, you should choose one with larger metric tons, or the air conditioner will not be cool, or overused to break early!

Other power-saving tips: 
✅Select lower “Energy Efficiency Rating Labeling” and efficient air-conditioner.

✅Choose a high CSPF (cooling seasonal energy factor) model. As long as CSPF is higher by 0.1, it means you can save about 2~3% of electricity!
