The invention belongs to the field of heat pump systems, and particularly relates to a vehicle-mounted heat pump system and a vehicle, a first compressor and a second compressor are arranged, a heat source and a cold source are provided by the two compressors, a PTC heater is used for heating assistance, and a refrigerant loop is switched in cooperation with a first labyrinth valve and a second labyrinth valve; when the driving system works, waste heat generated when the driving system works can be used for heating the battery pack, in the heating mode, the liquid cooling condenser can be used as an evaporator (cooling high-temperature cooling liquid in the second cooling liquid pipeline), in the system refrigeration mode, the liquid cooling condenser can be used as a condenser (cooling the liquid cooling condenser through a radiator), and the scheme that the two compressors are connected in parallel is adopted; the compressor cost is controllable, the double-compressor scheme is adopted, the refrigerating capacity adjusting range is wide, the adaptive capacity is high, and the problems that a single-compressor system is insufficient in refrigerating capacity, and large-refrigerating-capacity compressor products are immature and high in price are solved. In addition, the heat pump unit is high in integration level and convenient to install and arrange.
