In order to replace Positive Temperature Coefficient (PTC) electric heater in vehicle thermal management, this paper studied the heating characteristics of the triangular cycle through experimental and theoretical methods and proposed corresponding control strategy. First of all, in terms of component selection, the paper proposed that the triangular cycle had higher performance requirements for the condenser and electric expansion valve. Secondly, the bench test obtained a heating capacity of approximately 6 kW. Thirdly, the impact of different electronic expansion valve openings, air conditioner unit inlet air temperature and inlet air volume on performance was studied through the checked model, and it was found that the larger opening help the compressor to exert greater capacity and obtain greater heating capacity. Under high inlet air temperature and high outlet pressure condition, the triangular cycle has greater heating capacity. Finally, the paper proposed a triangular cycle control map covering 2 000 ~ 6 500 r/min compressor speed and -20~-10 ℃ inlet air temperature.
