Theoretically, the higher the set temperature of air conditioning refrigeration, the more energy is saved. Generally, the set temperature of air conditioning refrigeration in summer is better than 26 degrees, and the set temperature of heating in winter is better than 24 degrees.

When the air conditioner is in refrigeration operation, the higher the set temperature of the indoor unit, the smaller the temperature difference between indoor and outdoor air, the smaller the cooling loss and the smaller the average working load of the air conditioner. Generally speaking, the more electricity is saved, the lower the power consumption per unit time.

Air conditioning heating operation, the lower the set temperature of the indoor unit, the smaller the temperature difference between indoor and outdoor air, the smaller the heat loss, the smaller the workload of air conditioning, the smaller the power consumption per unit time, the smaller the power loss, and the more energy-saving.

In order to achieve maximum energy saving on the basis of ensuring the temperature adjustment effect of air conditioner, the return air filter of indoor unit of air conditioner should be cleaned regularly to improve the working efficiency of fan motor of indoor unit of air conditioner and the effective utilization rate of electric energy.
