The double-medium complementary type heat pump device comprises a user side heat exchanger, one side of the connecting end of the user side heat exchanger is communicated with an expansion valve, the other side of the connecting end of the user side heat exchanger is communicated with a compressor, the expansion valve and the free end of the compressor are communicated with a gating type heat exchanger unit, and the gating type heat exchanger unit is communicated with a heat exchanger. The gating type heat exchange unit, the expansion valve, the user side heat exchanger and the compressor are connected in series to form a closed loop. The air source and the water source are jointly utilized and complemented cooperatively, and compared with the mode that air serves as the only heat source, the operation energy efficiency can be improved; and compared with water serving as a unique heat source, the operation cost can be reduced. Double-medium complementary operation of one unit is achieved, stable heating of th
