摘要
为了掌握地源热泵地埋侧土壤的吸热放热特性,以某高校地源热泵供暖供冷为例对地埋侧土壤的吸热放热特性进行了研究,对 6 口地埋井在纵向按照每 10 米一个测点进行了温度监测,经过 1a的监测数据分析得出,热泵系统一年内向地下的净排热量为 10560.1GJ,热不平衡率为 61.8%,存在热累积现象.分析了岩土体在供暖季、过渡季、制冷季的温度变化情况,换热区域地层平均温度升幅在 1.65-2.24℃之间,平均累计上升 1.89℃,为该地区同类项目的开发具有一定的借鉴作用.
Abstract
In order to understand the heat absorption and release characteristics of the soil on the ground side of a ground source heat pump,this article takes the heating and cooling supply of a certain university's ground source heat pump as an example to study the heat absorption and release characteristics of the soil on the ground side.Six underground wells were monitored longitudinally at a measurement point every 10 meters.After a year of monitoring data analysis,it was found that the net heat output of the heat pump system to the ground within a year was 10560.1GJ,and the thermal imbalance rate was 61.8%,There is a phenomenon of heat accumulation.Analyzed the temperature changes of rock and soil during the heating season,transition season,and cooling season.The average temperature rise of the formation in the heat exchange area is between 1.65 and 2.24℃,with an average cumulative increase of 1.89℃.This provides a certain reference for the development of similar projects in the region.
