AI Technical Summary
Technical Problem
In large cold storage facilities, uneven distribution of condensing units leads to uneven temperature distribution.
Method used
The cold storage refrigeration area is divided into multiple sub-areas by the first and second dividing lines. Normally open equipment and switching equipment are set up. The equipment is classified according to its positional relationship with the dividing lines, and the operation of the equipment is controlled according to the preset control logic.
Benefits of technology
This achieves energy savings while ensuring temperature uniformity within the cold storage, avoiding the problem of uneven temperature caused by frequent operation or non-operation of some condensing units.

Abstract
The application discloses a group operation control method, a centralized controller and a refrigeration system of a cold storage. The method is applied to a refrigeration system with multiple refrigeration devices, and comprises the following steps: a refrigeration area is divided into multiple sub-areas through a first division line and a second division line; the first division line and the second division line both pass through the geometric center of the refrigeration area; according to the positional relationship between the refrigeration devices and the first division line and the second division line, the refrigeration devices are set as always-on devices and switching devices; and the operation of the always-on devices and the switching devices is controlled according to a preset control logic. Through the application, the temperature in the cold storage can be ensured to be uniform while energy consumption is saved.
