Abstract: PURPOSE: A directly circulating geothermal heat pump system is provided to reduce the possibility of damage to a heat pump and to simplify a collecting structure for refrigerant oil. CONSTITUTION: A directly circulating geothermal heat pump system comprises a heat pump, an underground heat exchanger, an opening control valve(170), and a control unit. The underground heat exchanger is connected to a first refrigerant pipe to the heat pump so that a refrigerant of the heat pump can directly flow into the underground heat exchanger. The underground heat exchanger collects the refrigerant to a second refrigerant pipe of the heat pump while absorbing geothermal heat from the underground to the refrigerant. The underground heat exchanger is inserted into an inlet hole punched on the underground and includes multiple branch pipes(150). The branch pipes are joined to multiple bundle pipes(141) and are connected to the first refrigerant pipe or the second refrigerant pipe. The opening control valves are individually installed in the bundle pipes in order to controls the opening angle. [Reference numerals] (AA) Heat pump

Abstract: PURPOSE: A transcritical rankine cycle system is provided to reduce the loss of exergy in a heat exchange process by realizing an alternating heat transfer process and increase output of a cycle by sufficiently absorbing heat from a heat source. CONSTITUTION: A transcritical rankine cycle system comprises next steps. Working fluid flows into a condenser, heat-exchanges with cooling water and is condensed in a low temperature/pressure liquid state to the liquid point of a saturation liquid line. After the condensing, working fluid is pressed in a low-temperature and high-pressure state to the liquid point beyond the saturation liquid line at supercritical pressure by the pump. After the pressing, working fluid is heated by a heat source in an initial liquid state and then to over the saturation line of a critical point due to supercritical pressure in the pressing process.
