Abstract：
In order to solve the problems of high initial investment and large fluctuations in heat generation in heat pump systems, it is proposed to couple air-source heat pump systems with conventional cold and heat source systems. In this paper, three dimensions for calculating the installed ratio of air-source heat pumps in coupling systems and two operation modes of parallel and series connections are analysed, and the recommendations for the supply and return water temperatures of the coupling system are provided.
