A cooler system includes a plurality of cooler units; a condensed water flow path, an aqueous medium in the condensed water flow path sequentially flowing through each of the cooler units; a cooling water flow path, an aqueous medium in the cooling water flow path sequentially flowing through each of the cooler units in a flow direction opposite to a flow direction of the aqueous medium in the condensed water flow path; a plurality of current sensors used for detecting working currents of the cooler units; water temperature sensors used for detecting an entering water temperature and a leaving water temperature of the cooling water flow path; at least one virtual temperature sensor arranged between the cooler units and used for acquiring a middle water temperature between the cooler units; and a controller.

Chiller system, method for obtaining middle water temperature and control method thereof

A refrigeration system, a fault diagnosis system and a fault diagnosis method for the refrigeration system, a controller and a storage medium. The fault diagnosis method includes: receiving a fault alarm sent by an associated refrigeration system, and acquiring a fault cause list associated with the fault alarm; determining whether to run a fault diagnosis system associated with the fault alarm; and when the fault diagnosis system associated with the fault alarm is run, checking the associated refrigeration system sequentially according to the fault cause list, and acquiring a fault cause and a repair means list associated with the fault cause.
