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

The invention relates to a solar suction-typed cooling and ground source heat pump coupling and combined supplying system which comprises a solar heat collector, a buried heat exchanger as well as an evaporator, a compressor and a condenser that are connected end to end, and has the following structure characteristics: the solar heat collector is serially connected with a heat-accumulating hot water tank by a first inlet and outlet pipe bank, the heat-accumulating hot water tank is serially connected with a suction-typed cooling machine set by a second inlet and outlet pipe bank, the suction-typed cooling machine set is serially connected with a cooling tower by a third inlet and outlet pipe bank, the suction-typed cooling machine set is communicated with an air conditioner inside an air conditioning room by a fourth inlet and outlet pipe bank, the buried heat exchanger is communicated with the condenser by a fifth inlet and outlet pipe bank, and the evaporator is communicated with the air conditioner inside the air conditioning room by a sixth inlet and outlet pipe bank; water pumps, reversing valves and/or electromagnetic valves are arranged between the first, the second, the third, the fourth, the fifth and the sixth inlet and outlet pipe banks or in each pipe tank.
