I. Introduction
The CCHP-HP coupling system is a more typical form of air conditioning cold and heat sources. Compared with the energy supply system where the CCHP system completely meets the building’s cooling and heating load requirements (according to the distributed energy system designed with heat and power), the CCHP-HP coupling system bears the annual appearance hours through a relatively low initial investment of heat pump units With less peak load, the CCHP unit mainly bears more basic loads per year, which can increase the annual equivalent full-load operating hours of the CCHP unit and improve the system economy [1].
