Solar absorption type refrigeration and earth source heat pump coupling and combined supplying system

The utility model relates to a solar absorption type refrigeration and earth source heat pump coupling and combined supplying system which comprises a solar heat collector, a buried heat exchanger, and an evaporator, a compressor and a condenser which are connected end to end. The system is structurally characterized in that the solar heat collector is connected with a heat storage hot water tank in series through a first incoming and outgoing pipe group, the heat storage hot water tank is connected with an absorption type refrigerating unit in series through a second incoming and outgoing pipe group, the absorption type refrigerating unit is connected with a cooling tower in series through a third incoming and outgoing pipe group and communicated with an air conditioner in an air conditioning room through a fourth incoming and outgoing pipe group, the buried heat exchanger is communicated with the condenser through a fifth incoming and outgoing pipe group, and the evaporator is communicated with the air conditioner in the air conditioning room through a sixth incoming and outgoing pipe group; water pumps, reversing valves and/or solenoid valves are arranged among the first incoming and outgoing pipe group, the second incoming and outgoing pipe group, the third incoming and outgoing pipe group, the fourth incoming and outgoing pipe group, the fifth incoming and outgoing pipe group and the sixth incoming and outgoing pipe group or in each pipe group.
