The invention provides a refrigerant loop and a vehicle heat management system. The refrigerant loop comprises a compressor, a first heat exchanger, a second heat exchanger and a reversing valve. The input end of the compressor is connected with a third interface of the reversing valve; the output end of the compressor is connected with a first connector of the reversing valve. A first input end of the first heat exchanger is connected with a second interface of the reversing valve; the first output end of the first heat exchanger is connected with the first input end of the second heat exchanger; a first output end of the second heat exchanger is connected with a fourth interface of the reversing valve; the reversing valve is configured to control the flow direction of a medium in the refrigerant loop. According to the refrigerant loop, refrigeration and heating of the refrigerant loop can be achieved only by arranging the compressor, the reversing valve, the first heat exchanger, the second heat exchanger, the expansion valve and other main components. Various bypass loops do not need to be arranged, and the structure of the refrigerant loop is simplified. And the problems of flow resistance, heat leakage, liquid condensation, oil return, filling and the like caused by a complex structure can be avoided.
