对于总热负荷与总冷负荷不平衡的建筑,单独采用土壤源热泵系统供暖或供冷时,系统运行末期土壤温度发生很大的变化,降低了系统的运行性能。针对此类建筑,搭建太阳能-土壤源串联复合式热泵系统,从集热器单位面积流量、存储水箱体积的影响因素出发,研究供暖期热泵机组蒸发器侧进水温度、系统运行性能和能耗的变化情况,为常规土壤源热泵系统引起的土壤热平衡问题提出解决方案,为今后的实际工程设计及应用提供参考依据。
For buildings with unbalanced total heat load and total cooling load, when the ground-source heat pump system is used alone for heating or cooling, the temperature of the soil at the end of system operation changes greatly, which reduces the system’s operation performance. In view of such buildings, solar energy - soil series tandem heat pump system is set up. Based on the influence of collector unit volume and storage tank volume, the inlet water temperature, system performance and energy consumption of heat pump heat pump units are studied. This paper presents a solution to the problem of soil heat balance caused by conventional ground source heat pump system and provides a reference for the future practical engineering design and application.
