地源热泵地温场研究现状及土壤热失衡解决方案OA

The research status of the geothermal field of ground-source heat pumps is introduced,and the causes of soil thermal imbalance as well as correspond-ing solutions are summarized.The original geothermal measurement methods include direct monitoring,opti-cal fiber temperature measurement,embedded plati-num metal thermistor testing,resistivity temperature measurement,hydrochemical method,and electrical wellbore temperature estimation.The ground tempera-ture field of ground source heat pump can be predicted and analyzed by establishing mathematical model and using simulation software to establish ground tempera-ture prediction model.The direct monitoring is also an important means of obtaining geothermal field data.The accumulation of soil cold and heat due to signifi-cant differences in user cooling and heating loads is the main reason for soil thermal imbalance.To address this issue,measures such as heat recovery technology,operation strategy optimization,auxiliary heat dissipa-tion,and heat supplementation can be adopted.
