Study of economic feasibility of a compound cool thermal storage system combining chilled water storage and ice storage

For the purpose of grid peak load shifting, chilled water storage has been paid more and more attentions to integrated with air-conditioning system. In this paper, a new air conditioning system with directly chilled water storage is given. With peak-valley Price, cost for power consumption can be saved 15%-20% by coordinated operation between chilled water storage system and air conditioning system. By sensitivity analysis of system economic performance on ratio of peak price to valley price, it is revealed that with much higher ratio of peak price to valley price, not only system economic performance can seldom be improved, but also chilled water storage is restricted for engineering utilization. This paper supplies theory reference for engineering application of chilled water storage technology.

Due to higher energy consumption for air-condition system and higher energy cost for building, the combination between peak-valley power price and chilled energy storage is provided and paid more and more attention. This paper introduced main chilled energy storage technologies and analyzed their economic performance, chilled water storage and ice storage both have good performance, but they fit for difference conditions, for chilled water storage, it doesnt need to add chiller for below zero temperature and fits for energy saving reform, and ice storage can meet the need of new air-conditioning system, which supplies a new application direction for energy cost saving operation in building.
