Case analysis of soil temperature field during operation of ground-source heat pump systems
摘要：
对某一地源热泵系统的实测土壤温度场数据进行了初步分析，总结了冬季、夏季及过渡季工况下土壤温度场的变化特点及其影响因素。指出地源热泵系统运行过程中的地下能量堆积问题是一个长期效应，记录分析土壤温度场的长期变化趋势对于调控地源热泵系统的运行状态具有积极的指导作用，有利于保证系统的长期可靠性和节能性。
Abstract：
Analyses the test data of the soil temperature field during the long-term operation of a practical ground-source heat pump (GSHP) system, and summarizes the change characteristics of soil temperature field and the influencing factors under different operation conditions of winter, summer and transitional seasons. Points out that the underground energy accumulation is a long-term effect for the operation of GSHP systems. It is important to record and analyse the long-term tendency of the soil temperature field changing, which is useful to make a rational adjustment on the operation mode of GSHP systems and guarantee a better reliability and energy efficiency.
