Operation strategy of ground-source heat pump system for railway passenger station based on soil load characteristics
摘要：
引用地源热泵系统的土壤负荷概念及其主要特征参数，包括土壤负荷的总量累积特性、不平衡率、变化特性、持续性，对土壤负荷不平衡率高且具代表性的夏热冬冷地区大型铁路客站的复合式地源热泵系统的全年运行策略进行了分析，认为铁路客站采用地源热泵系统时应制定合适的运行策略，设计中也应考虑一些必要的措施。
Abstract：
Based on the soil load concept and its main characteristic parameters of the ground-source heat pump system, including the total cumulative characteristic, the imbalance ratio, the variation characteristic and the continuous feature of soil load, analyses the annual operation strategy of a hybrid ground-source heat pump system installed in a large-scale railway passenger station in hot summer and cold winter zone, where the representativeness is obvious and the imbalance ratio of soil load is high. Suggests that when the railway passenger station adopts the ground-source heat pump system, the appropriate operation strategy should be developed, and some necessary measures should be considered in the design.
