Monitoring and Analysis of Ground Temperature Field in a Ground Source Heat Pump System of a University in Hebei Province
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.
