摘要： A heat-pipe type heat extraction integrated with combined cooling power and heating exploitation-utilization integrated geothermal system includes an underground heat pipe, a steam pump, a first absorption bed, a second absorption bed, a first condenser, an electronic expansion valve, an evaporator, a liquid storage tank, a balance valve, a steam turbine, an generator connected to the steam turbine, a second condenser, a heat utilization device connected to the second condenser, a pressurizing pump connected to the second condenser, and relevant linkage valve assemblies. The system controls a flow direction and a flow rate after heat pipe steam is extracted from the ground through the steam pump and the regulating valves on the refrigeration side and the power generation side, so as to select the refrigeration/electric heating single-mode heat utilization or adjust flow distribution during refrigeration/electric heating dual-mode combined use.

摘要： A heat pump system and a method for implementing efficient evaporation by using a geothermal well are provided. The system includes a stepped underground evaporator, a compressor, a condenser, a liquid storage tank, and a throttle. The underground evaporator includes an inner pipe and an outer pipe. The inner pipe is designed into a multi-section structure. Each section includes a gas guiding pipeline, a baffle plate, and a seepage hole. Under the action of the structure, a liquid working medium flowing into the underground evaporator flows downwards along an inner wall of the outer pipe, and absorbs heat from an underground rock mass and gasifies into a gas working medium; and the gas working medium flows upwards to ground. Compared with the prior art, neither gas-liquid re-entrainment nor a liquid accumulation effect can occur in the underground evaporator designed according to the system and method.
