【摘要】 地下换热器是地源热泵的重要组成部分,竖直U型管是最常见的地下换热器形式。运用地热之星,计算和模拟了山东省某地区实际工程地源热泵空调系统。讨论和分析了循环液进出口温度,土壤热物性,换热器结构,地埋管管径对单位孔深换热量的影响,整理分析得出的上述因素对单位孔深换热量的影响,可以作为实际工程优化设计的依据。更多还原

【Abstract】 The ground heat exchanger is an important component of the Ground source Heat Pump (GSHP) and the U-tube is most commonly used ground heat exchanger. Geo Star is used to calculate and simulate the GSHP air conditioning system of a certain area in Shandong province. Discuss and analyze the effect of the inlet and outlet temperature of the circulating water, thermal physical property of soil, structures of heat exchangers and the size of the buried tubes on the heat exchange of unit hole depth. Through setting and analyzing the factors above how to affect the heat exchange of unit hole depth, can be regarded as the reference of optimization design for practical project.更多还原
