Reason: First of all, let's talk about what total pressure efficiency means. The popular understanding is that the power output by the motor of the range hood is converted into the ratio of the power carried by the exhaust air volume of the range hood, that is, the ability of the range hood to effectively use the motor power. This ability will be reflected in the level of energy efficiency. The higher the total pressure efficiency of the range hood, the better the energy efficiency grade, and vice versa.
Industry Status: At present, the total pressure efficiency of range hoods is above 23%, which is a very good level.
Suggestion: When buying a range hood, you generally don't need to refer to this indicator. Pay attention to the brand when you buy it and see what its energy efficiency rating is. If you buy a first-class brand range hood with first-class energy efficiency, you don't have to worry too much about the problem of low total pressure efficiency.
