摘　　要：地源热泵热回收机组是一种新型的生活热水热源,结合具体工程设计,讨论了机组的设计选型、换热设备及贮热设备的设计计算中应注意的一些关键点,提出了合适的工程措施建议。在实际工程中发现了给排水技术措施中一个换热设备计算公式有明显的错误,该错误有可能给工程带来不可挽回的损失;给排水规范及技术措施关于换热设备计算中片面强调面积计算,忽略了过流量计算及水力损失计算;贮热设备计算中对地源热泵的可操作性不强;地源热泵产品样本对热水出水水温的标识对设计人员有误导作用,使设计人员有可能产生错误的计算结果,项目业主在使用过程中达不到设计要求。Ground source heat pump heat recovery unit is a new type of domestic hot water heat source. Combined with a specific engineering, the design selection of the unit and some key points needing attention in the design calculation of the thermal storage equipment and heat exchange equipment were discussed, and appropriate engineering measures were put forward. An obvious error in a calculation formula of heat exchange equipment in water supply and drainage technical measures was found in the ac- tual engineering. The error may bring irreparable damage to engineerings. The water supply and drainage standards and technical measures put one-sided emphasis on area computation in calculation of heat exchange equipment, and ignore the calculation of overflow and hydraulic loss. The operability of ground source heat pump is not strong in the calculation of heat storage equipment. The indication of outlet hot water temperature in ground source heat pump product samples has a misleading effect on designers, which leads to that the designers may have a calculation error, and the design requirements can not be reached in the use process of project owners.
