摘要
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。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%。
Embedded temperature sensor and thermal response test （TRT） is common method to obtain ground heat exchanger design parameter-rock-soil initial temperature.But they are limited to fund,time,conditions for execution and so on.Depending on the ground source heat pump system of Nanhulinyu of Xinyang,the rock-soil initial temperature is achieved by theoretical analysis and comparing 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 ％.
