Solar photovoltaic -commercial electricity dually driven heat pump system with cold/heat storage

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.
