Abstract：
Based on the advantage and disadvantage analysis of commonly used three chilled water storage systems, presents the improved system. Describes in detail the working principle and operating strategies and performs the economic analysis. As a result, the system features simple flow process and stable and reliable operation, and can solve the problems existed in original system such as lower efficiency of refrigerating machines, extra energy consumption of pumps in open systems and electric valve damage resulting from possible over-large pressure difference.
