冰蓄冷空调系统的研究现状

Research status of ice storage air conditioning system

随着我国经济的快速发展,空调系统已经成为建筑中必不可少的设备,但空调的耗电量巨大,约占建筑用电量的60%,在用电高峰时段,电力系统的供应明显不足,甚至出现拉电限电等情况.冰蓄冷不仅能降低系统的运行费用,还可以很好地实现削峰填谷的作用.在夜间的低谷电期,利用蓄冷装置将冷量储备,在尖峰阶段释放冷量,以满足建筑冷负荷的需要.本文主要介绍了冰蓄冷系统的制冰方式、制冰流程以及运行策略,阐述国内外对冰蓄冷系统技术、运行策略、经济性等方面发展现状,结合冰蓄冷系统的优缺点,展望其在我国的发展前景以及使用时应该注意的问题.

With the rapid development of economy in China,air conditioning system has become an essential equipment in buildings,but the power consumption of air conditioning is huge,accounting for about 60%of the power consumption of buildings.In the peak hours,the supply of the power system is obviously insufficient,and even the situation of power pulling and power limiting occurs.Ice storage can not only reduce the operating cost of the system,but also realize the function of peak cutting and valley filling.In the off-peak period at night,the cold storage device is used to store the cold quantity and release the cold quantity in the peak stage to meet the needs of the cooling load of the building.This paper mainly introduced the ice-making method,ice-making process and operation strategy of ice storage system,expounded the development status of the technology,operation strategy and economy of ice storage system at home and abroad,and forecasted the development prospect of ice storage system in China and the problems that should be paid attention as using.
