A new operating mode of air-conditioning systems with thermal storage

Load imbalance of power grid leads to more peak-load power station built with huge capital cost and some environment effects. As a peak shifting technology, thermal storage technology has attracted more attentions. A new operating mode of chilled storage process integrated with air-conditioning system is proposed, and its performance is analyzed. The results show that the new operating mode can get more than 5% of power saving than the traditional mode, and achieve more than 40% power cost saving based on air-conditioning without chilled storage, both of which result from the good integration of chilled storage process with air-conditioning system. The new operating mode gives the new direction of thermal storage technology application.
