摘要 地源热泵以其环保特性越来越受到空调界的重视。地下埋管换热器是地源热泵研究的重点和难点之一,不同的地质条件会有不同的换热效果。因此,大连理工大学针对大连地区地质为岩石这一特点建立了地源热泵实验系统。由于单管换热特性是研究地源热泵地下埋管特性的基础,所以实验采用电加热器控制单管的进口水温,使其保持恒定,得出了75m埋深地下换热器夏季2小时内单独运行时在不同进口水温和水流量情况下的换热特性。 GSHP (Ground Source Heat Pump) has been paid more and more attention by the air conditioners for its environmental protection character. The underground exchanger is one of focal and difficult points in the studying of GSHP. Different geological condition will cause different result of the changing heat. The GSHP experimental system has been set up in Dalian University of Technology for this character of rock in Dalian region. Heat transfer character of single heat exchanger is the basement in the study of underground heat exchangers. In this experiment, the electric heating apparatus is used to keep the water in a stable import temperature of the single heat exchanger. Then the heat transfer character is got when the single heat exchanger underground 75 meter deep operates for two hours in different import water temperature and different water flow.
