Buffer Tank Discharge Strategies in the Case of a Centrifugal Water Chiller

In this article, energy optimization of the cooling system IKEA Budaörs is carried out. The served by a centrifugal water chiller and includes large-volume buffer tank. facility operates hydraulic storage tank only during transitional period. main goal to reduce consumption changing operating strategy existing system. To test strategies, operation thermal load shopping center summer season had be simulated find best strategy. A hybrid method (real data calculated values) was used in simulation. three scenarios examined show that annual number hours can reduced using with right scenarios, 30% improvement achieved. possibility significantly limited fact heat exchangers were sized for low forward temperatures. By re-sizing exchangers, utilization could considerably improved conditions close peak load.
