The performance of heat pump air-conditioning system under heating conditions is studied, and a fuzzy control strategy is proposed. The heating condition model of the heat pump air conditioning system is built in AMESim, and the control strategy model is established by Simulink for joint simulation, with the cab temperature as the target temperature of the system performance. Compared with the traditional control strategy, the control strategy designed in this paper can rapidly increase the temperature of the passenger compartment to the target temperature, and the temperature control accuracy is more accurate, the callback time is shorter, and the comfort is better.
