Abstract: Compares the energy consumption of the air-source heat pump under different control logics.Mainly through two dimensions, one is the single-point COP test results, the other is the 24 h power consumption test results; based on the above two test results, the energy-saving control strategy of heating machine is obtained. The experimental results show that the power consumption of the unit can be reduced from 94. 9 kW·h to 79. 3 kW·h, which is 15. 6 kW·h, and the energy saving can be improved by 19.6% under the optimized control logic when the ambient temperature is -12℃ and the water temperature is set at 45℃ (return water temperature). Through the experiment, it can provide reference for the design of energy saving control strategy of air source heat pump. At the same time, the change of comfort (temperature field) is also compared.
