Heat pump air conditioning can significantly improve the energy consumption of electric vehicles under winter heating conditions and increase the mileage of the whole vehicle.However,due to the relatively complex system architecture and the large number of components applied,the high cost has become a limiting factor for the widespread application of heat pump technology.In this paper,a set of heat pump system with relatively simple structure is designed to meet the heating needs of the whole vehicle in winter.Through the construction and testing of the system bench,the charging test of the system was carried out,and its heating performance under-7℃working condition was analyzed.The system was installed on the whole vehicle for wind tunnel testing,and the heating characteristics of the heat pump air conditioning system under winter conditions were studied,which fully verified the feasibility of the heat pump air conditioning system in practical engineering applications.
