摘要(Abstract):

针对建筑物空调系统电力负荷日益增加 ,特别是电力高峰时段的负荷较大 ,提出了一种利用土壤蓄冷与土壤耦合热泵集成系统的设想。该系统是将蓄冷技术与土壤耦合热泵系统有机地结合起来 ,充分利用了冻土蓄冷技术与土壤耦合热泵系统的优点 ,将土壤耦合热泵系统的地下埋管换热器兼作蓄冷装置 ,利用夜间电力的低谷期 ,将冷量全部或部分地贮存到地下 ,以供白天用电高峰期空调用。本文给出了该系统的设计思想和试验方案 ,为推广与应用该系统打下理论基础
The integrated frozen soil thermal storage and ground-coupled heat pump system is presented basing on the condition of the increasing electric load of the building air conditioning system, especially the higher electric load during on-peak period. The system combines the ice storage technology and the ground-coupled heat pump system, and the advantages of the frozen soil thermal storage and ground-coupled heat pump system are fully utilized. In this system, the geothermal heat exchangers of the ground-coupled heat pump system are served as the ice storage equipments at one time. Using the electric power during nighttime (off-peak period), the cooling load is stored on the underground soil partially or fully to satisfy the air conditioning load requirement during daytime (on-peak period). The design thought and experiment scheme are presented and the theoretical foundation is supplied to make this system generally applicable.
