地源热泵岩土体初始温度确定方法的实例分析

埋设温度传感器与岩土热响应试验是获取地源热泵换热器设计参数—岩土体初始温度的常用方法，然而埋设温度传感器与岩土热响应试验往往受资金、时间、施工条件等的限制。本文以信阳南湖林语地源热泵系统工程为例，通过理论分析计算其岩土体初始温度，并与用岩土热响应试验与埋设温度传感器所测得的岩土体初始温度作对比分析，结果表明理论计算的结果与埋设温度传感器和岩土热响应试验所得成果相差不超过5%。

Case study on the determination of the rock-soil initial temperature

Embedded temperature sensor and thermal response test (TRT) is common method to obtain ground heat exchanger design parameter - rock-soil initial temperature. But embedded temperature sensor and TRT are limited to fund, time, conditions for execution and so on. This text depends on the ground source heat pump system of Nanhulinyu of Xinyang, achieve the rock-soil initial temperature by theoretical analysis and compare the outcome with the embedded temperature sensor and TRT. The result shows that the consequence achieved by each way is alike and the error is limited to 5%.
