Research on “heat pump plus boiler” air conditioning heat source system of a shopping center in Changsha

Based on the “dual carbon” policy and the local energy price policy, in order to make full use of the advantage of low carbon emissions of air-source heat pumps, a detailed technical economy analysis of the “heat pump plus boiler” air conditioning heat source system of a shopping center in Changsha is carried out. The optimal ratio of air-source heat pump and boiler is determined with the goal of the best economy in the whole life cycle. According to the connection form of the air-source heat pump and the boiler in the system, the control strategies and control requirements of series and parallel connection forms of the heat source equipment are presented, and the suggestions are given in combination with the ratio of the air-source heat pump and the boiler.
