Refrigerator control device, refrigerator system, refrigerator control method, and program

Abstract

[Problem] To provide a refrigerator control device that is capable of stabilizing a cold water outlet temperature in controlling a plurarity of operating refrigerators without requiring additional configurations, such as a bypass pipe and a two-way valve, and to provide a refrigerator, a refrigerator system, a refrigerator control method, and a program. [Solution] A control device for controlling a first refrigerator and a second refrigerator that are connected in series comprises an expansion process control unit that, in response to a load increase, performs control so that, when the control device expands the number of operating refrigerators from only the first refrigerator to both the first and second refrigerators, a refrigeration capacity of the first refrigerator is equal to or less than a refrigeration capacity at the start of an expansion process during the period from the start to the completion of the expansion process.
