Effect of the Specification of Chilled and Hot Water Coil on Efficiency of Air Conditioning System with Water Thermal Storage

摘要

This study aims to examine the influence of the specification of heat exchange coils on the operation of air conditioning systems with water thermal storage. In this study, the influence of the specification of the air-handling unit coil on the operating condition of the water thermal storage system is examined using a simulation tool. The results indicate the importance of properly maintaining the relationship between the thermal storage tank capacity and secondary side temperature difference in both design and operation stages. Furthermore, this study shows that significant attention should be paid to the input of coil specifications when using the simulation tool.
