Influence of different design schemes in series chiller upstream ice storage systems on system operation

Qualitatively analyses several design schemes of the series chiller upstream ice storage system, and points out that the combination and separation of the bypass pipe connection points of the ice storage tank and the plate heat exchanger will make the load distribution of the system different. Recommends that the bypass valve of the chiller should be designed with frequency conversion glycol pump. Analyses the reasons and effects of using the frequency conversion glycol pump, and proposes its frequency conversion control logic.
