Operation strategy of ground-source heat pump system for railway passenger station based on soil load characteristics

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.
