地埋管地源热泵土壤热不平衡预警方法
Early-warning of soil heat imbalance for ground-source heat pump systems
摘要：
针对夏热冬冷地区地埋管地源热泵系统运行过程中的土壤热不平衡问题，介绍了建立预警体系的方法。以土壤温度标准曲线作为预警指标，考虑气象条件的随机性，制定了3种气象参数条件下的标准曲线。介绍了预警阈值范围的确定，针对系统不同运行时期的特点给出了土壤温度允许的偏差范围。

Abstract：
Presents the method of establishing an early-warning system aiming at probable occurence of soil heat imbalance in operation of ground-source heat pump system in hot summer and cold winter area. Takes soil temperature standard curve as the early-warning index, considering the randomness of weather conditions, works out the standard curves in accord with three kinds of meteorological parameters. Describes the determining method of the early-warning threshold range, and gives the allowable deviation range of soil temperature in different operation periods.
