The more unheard-of brands are cheaper, the less guaranteed the quality is, and the more likely it is to need after-sales service.

The most energy-saving air conditioner is not what kind, but how to use it.

although energy efficiency ratio or energy efficiency grade can be seen for energy-saving air conditioners. For the same power consumption of 1W, the first-class energy efficiency can get 3.6W cooling capacity, while the third-class energy efficiency can only get 3.2W cooling capacity. Therefore, level 1 energy efficiency will save electricity. Although the air conditioner with high energy efficiency rating and energy efficiency ratio saves electricity, it still consumes electricity if it is used improperly.

in fact, the air conditioner consumes a lot of electricity; Mainly depends on the method of use.

for example, if the temperature is set at 16 degrees, it is impossible to stop the compressor of the constant frequency air conditioner, so the nominal power consumption can be easily calculated.

if it is a variable frequency air conditioner, if the temperature is set at 16 degrees, the air conditioner may always operate at high frequency and high power, and the power consumption may be more than the fixed frequency.

if the set temperature is 26 degrees, the fixed frequency can be operated intermittently, and the frequency conversion can be operated at reduced frequency and power, so that the power consumption can be lower than the nominal power consumption, and the effect of energy saving can be achieved.

every 1 degree increase in the set temperature can save electricity by 6~1%. This power saving range does not lose the energy efficiency ratio.

Why do you suggest setting 26 degrees?

From the research of human comfort; The most suitable ambient temperature for the human body is 27 degrees, and the temperature difference of thermal shock that the human body can bear is about 5 degrees (meaning going in and out between two different ambient temperatures, such as indoor and outdoor), so the most suitable setting temperature of the air conditioner at home is between 26 and 28 degrees.

setting this temperature can not only obtain a comfortable environment that is neither too hot nor too cold, but also save energy consumption, electricity and money.

It is also suggested to buy a variable frequency air conditioner, because when the variable frequency air conditioner reaches the set temperature, it will run at reduced frequency and power, which is the most energy-saving. At this time, the compressor will run at the most appropriate frequency, which is quiet and energy-saving, and the room temperature will be stable between plus and minus .5 degrees, which is the most comfortable.

therefore, the energy saving of air conditioners depends not on which kind they belong to, or even on energy efficiency, but on how to use air conditioners.
