1. A solar photovoltaic-commercial electricity dually driven heat pump system with cold/heat storage, characterized by comprising:

  • a compressor module including a DC compressor sub-system (A);

    a photovoltaic DC power source sub-system (K) for supplying power to said DC compressor sub-system (A);

    an air source condenser (D);

    a throttle device (G);

    an air source evaporator (I);

    a heat storage sub-system (C) coupled between said compressor module and said air source condenser (D), wherein said heat storage sub-system (C) contains heat storage phase change material (20) for absorbing heat from refrigerant;

    a cold storage sub-system (H) coupled between said throttle device (G) and said air source evaporator (I), wherein said cold storage sub-system (H) contains cold storage phase change material (39) for being frozen by said refrigerant;

    wherein said compressor module, said heat storage sub-system (C), said air source condenser (D), said cold storage sub-system (H), said throttle device (G), and said air source evaporator (I) form into a loop by pipe lines, for allowing refrigerant to circulate in said loop.
