为得到二级蓄冷机组在不同蒸发器进口温度下，机组和整个蓄冷系统效率随低温冷却水温的变化规律，本文搭建了乙二醇蓄冷系统实验台和地源热泵实验台，由一级地源热泵实验台负责二级蓄冷机组低温冷却水的供给。通过试验得到，在蒸发器进口温度一定时，降低冷却水进口温度可有效提高机组的效率，但冷却水温并不是越低越好，需综合考虑整个系统的运行状况。

In order to obtain the unit and the entire cold storage system ’ s efficiency with cryogenic cooling water temperature variation ,when the two-stage cold storage units in different evaporator inlet temperature .The glycol storage system and ground source heat pump system were built , the ground source heat system is responsible for low-temperature cooling water supply .Ob-tained by experiment , when the evaporator inlet temperature is constant , lowering the cooling water inlet temperature can effec-tively improve the efficiency of the unit , but not the cooling water temperature the lower the better , it needs to consider the opera-tional status of the entire system .
