Abstract: Enthalpy augmentation system can effectively improve the heat production of air source heat pump, so that the use effect of heat pump is greatly improved. This paper theoretically analyses the heating advantages of air source heat pump hot air fan system with supplementary air enthalpy technology over ordinary air conditioning system. By comparing the experimental results of supplementary air enthalpy system and ordinary air conditioning under different conditions of refrigeration and heating, the advantages of supplementary air enthalpy system in heating, refrigeration and comfort of use are obtained, which will promote and use supplementary air enthalpy air conditioning system. Provide technical support. At the same time, the operating range and conditions of gas-supplement enthalpy-increasing are studied, which can play a positive guiding role in optimizing the use of gas-supplement enthalpy-increasing technology, and also play a positive guiding role in the design of gas-supplement enthalpy-increasing heating system.
