Case study on energy saving operation of magnetic suspension water chillers with optimized operation regulation strategies

Taking the practical project of the cooling system of magnetic suspension water chillers in a scientific research building as an example, this paper studies the application characteristics of magnetic suspension water chillers, especially the method of realizing efficient and energy saving operation by optimizing operation regulation strategies. By analysing the problems existing in the operation process, the energy saving optimization operation strategy is studied, and the operation commissioning optimization is carried out. Through continuous monitoring, it is found that compared with the original operation mode, after the commissioning and optimization, the power saving of the system is 130 000 kW·h during the period from April to mid-November, and the annual operation is expected to save 237 000 kW·h. If the cooling tower can be further installed with frequency converters and updated optimization control strategies, there is still energy saving potential in annual operation.
