Chilled energy storage for air-conditioning system of buildings

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 doesn't 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.
