The invention provides a double-heat-source heat pump system with a motor stalling function. The double-heat-source heat pump system comprises a temperature sensor A1, a temperature sensor B, an electronic three-way valve, a valve B, an electric water pump, a heat exchanger A, a power motor, a valve A, a liquid-gas separator, a compressor, a water-cooling condenser, an electronic expansion valve, a valve C and a condenser. The double-heat-source heat pump system with the motor stalling function has three working modes, the first working mode is a single-heat-source heat pump working mode, and heat in air is converted into heat needed by heating of an electric vehicle air conditioner through the heat pump system; the second working mode is a double-heat-source heat pump working mode in a motor waste heat and air source form, and heating heat is provided for an electric vehicle air conditioner; the third working mode is a working mode that heat generated in a motor stalling mode and air source heat are used for providing a heat source for electric vehicle air conditioner heating; the problem that the heating capacity of an electric vehicle user utilizing a heat pump system is insufficient under the low-temperature condition is solved, and the heating capacity of the heat pump system is enhanced after motor stalling.

    本发明提供一种带有电机堵转的双热源热泵系统,包括温度传感器A1、温度传感器B、电子三通阀、阀B、电动水泵、换热器A、动力电机、阀A、液气分离器、压缩机、水冷冷凝器、电子膨胀阀、阀C、冷凝器;带有电机堵转的双热源热泵系统设有三种工作模式,第一种工作模式为采用单热源热泵工作模式,通过热泵系统将空气中的热量转换为电动车空调采暖所需热量;第二种工作模式为采用电机余热及空气源形式的双热源热泵工作模式,为电动车空调提供采暖热量;第三种工作模式为,采用电机堵转形式产生热量及空气源热量为电动车空调采暖提供热源工作模式;本发明解决电动车用户低温情况下利用热泵系统采暖能力不足问题,在电机堵转后增强热泵系统采暖能力。
