PROBLEM TO BE SOLVED: To provide a refrigerating/freezing device system capable of immediately carrying out information transmission or control when a request is generated. SOLUTION: The system comprises a refrigerating/freezing device 6a, an information board 31 connected to the refrigerating/freezing device 6a and having a transceiving means 32, and a server 33 having a transceiving means 34 and a trigger generating means 39. The transceiving means 32 issues a periodic UDP, the transceiving means 34 issues a request response UDP or a request response TCP to a periodic UDP transmission source address when a communication request is generated in the trigger generating means 39, and the information board 31 controls the refrigerating and freezing device 6a when the transceiving means 32 receives the request response TCP or the request response UDP.
