To obtain a central management system of freezing facility in which freezing/refrigerating showcases, which must be uncooled at the time of closing a shop, can be uncooled collectively without requiring individual switching operation utilizing an existing system for centrally managing the operational control of the showcases and which can be operated easily by anybody in the operational feeling similar to conventional one with no strange feeling.

In the central management system of various types of freezing facility installed in a shop, e.g. a supermarket, one solenoid valve controller 8 for turning off solenoid valves disposed in the various types of freezing facility in order to control refrigerant supply is connected with controllers 3 of the freezing facilities. Solenoid valves disposed in selected specific freezing facilities are turned off collectively with an output from the output means provided in one solenoid valve controller 8 to the controller 3 thus stopping operation of the freezing facilities.
