Abstract (en)
[origin: EP3163225A1] In a chiller system, any one of a plurality of chillers is designated as a master chiller. Out of the plurality of chillers, at least one chiller that needs a defrost operation sends a request for the defrost operation to the master chiller. The master chiller permits the defrost operation to the at least one chiller that has sent the request for the defrost operation in arrival order up to a predetermined number of chillers. At least one chiller on standby for the defrost operation sends the request for the defrost operation to the master chiller in a predetermined cycle. When there are multiple chillers that are on standby for the defrost operation, the master chiller permits a next defrost operation to one of the multiple chillers on standby in descending order of the number of the requests or a request time for the defrost operation.
