结合寒冷地区某办公楼地源热泵项目，介绍了浅层地热地质条件的测试结果。土壤热平衡分析结果表明，如果地源热泵机组全年向岩土体排热量为1．425 TJ，经过一个制冷季和一个供暖季后，岩土体温度升高幅度为0．30℃。运行数据分析结果表明，地源热泵冷凝器与蒸发器进出口温差在运行过程中通常小于设计温差，造成水泵能耗偏高，建议采用定温差、水泵变频调节的控制方式。

Combined with the project,presents the test results of ground-source heat pump under the shallow geothermal condition.The soil thermal balance analysis results show that the soil temperature increases by 0.3 ℃ after a period of cooling and heating season on condition that heat released from ground-source heat pump units to soil is 1.425 TJ.The analysis of operational data shows that temperature differences of entering and leaving water of condensers or evaporators on operation condition are commonly smaller than those on design condition for ground-source heat pump units,resulting in higher energy consumption of pumps.Suggests to apply the control mode of constant temperature difference and variable frequency of pump.
