Abstract

The present disclosure concerns a device and a method for chiller station management for providing chilled water to a load (30), a computer storage medium and a chiller station. The method for chiller station management includes: determining whether a chiller (10) with a low load exists in a chiller station and determining whether to allow to shut down one chiller (10) in the chiller station, when a certain chiller (10) in the chiller station transmits a surge risk signal; if yes, shutting down one chiller (10) in the chiller station to increase loads of other chillers (10); and if no, raising a chiller (10) outlet water temperature in the chiller station and/or lowering a cooling tower (20) outlet water temperature in the chiller station. The device and method for chiller station management according to the present disclosure provide a surge protection at a chiller station level, thereby effectively avoiding occurrence of surge in the chiller, and improving the efficiency and operation stability of the chiller station.
