摘要 通过土壤温度分布实测数据，分析了目前地下热响应实验中土壤初始温度测试结果的误差，实验表明，测试土壤初始温度与积分平均土壤温度接近。在浅层土壤温度分布理论模型的基础上，计算分析了测试土壤初始温度的季节变化特征。 关键词 地源热泵 热响应实验 土壤初始温度 积分平均土壤温度 Discussion on the initial ground temperature during thermal response tests By Wang Huajun★ and Qi Chengying Abstract Analyses the error of initial ground temperature during the thermal response test on the basis of the test data and the results show that the test initial ground temperature is close to the integral average ground temperature. Based on the theoretical model of shallow ground temperatures, simulates the seasonal variations of the test initial ground temperature.
