TWO STAGE HEAT PUMP COOLING AND HEATING APPARATUS USING GEOTHERMAL SOURCE

摘要

It is designed to provide a kind of underground heat binary cycle heat pump and cools and heats device and heated, high-efficient, heat is by feeding back remaining after condensation in the circulation of high temperature side, or improves cooling efficiency and produce the heat of hot water at high temperature and pass through transmitting ground. Reach the purpose, underground heat binary cycle heat pump cools and heats device, further includes: the 5th heat exchanger (104), one side are connected to first heat exchanger (102) and the first expansion valve (105); Heating agent circulation pipe (218) forms closed loop, the circulation for making heating agent circulation pipe (218) that can be contained in heat medium by connecting the 5th heat exchanger (104) of opposite and the 4th heat exchanger (214); Thermal medium circulating pump (215) is connected to the heating agent circulation pipe (218) in the path; In ground heat-exchanger embedment ground. Pass through the operation heat medium circulation pump (215) for the heat medium circulation line (218) that heat medium recycles, ground heat absorption is sent to the refrigerant (102) that the first heat exchanger condensation of remaining hot high temperature side is added after the 4th heat exchanger (214) from ground heat-exchanger, so that low temperature side refrigerant can is evaporated, well is worked as and is heated, the refrigerant of the high temperature side of heating is dispersed into ground connection and passes through ground heat-exchanger, when executing cooling down operation, wherein the heat of the refrigerant of high temperature side is absorbed into the 5th heat exchanger (104). ;The 2014 of copyright KIPO submissions
