A4-04 Ice Thermal Storage Applications in China Case Study

While ice storage has long been recognized as an effective technology to shift electric demand to off-peak periods to take advantage of low-cost off-peak electric rates, properly designed ice thermal storage system can also result in lower first cost, lower operating cost, and more energy efficient compared to non-storage system. This paper examines several recently installed ice thermal storage projects in China, and demonstrates that an ice thermal storage system, when fully integrated with the total building design, will reduce first cost, operating cost, and energy consumption.
