The present invention relates to a system for operating a complex refrigerator including a centrifugal type refrigerator, an absorption type refrigerator, and an ice storage type refrigerator. The system of the present invention comprises: a data input unit for receiving data supplied from the outside and storing the input information by type; a unit cost computing unit for, when unit cost information over time for each heat source is input through the data input unit, applying the unit cost information over time of each heat source to the specification of the refrigerator to compute the consumption costs of each refrigerator per the set heating value; a load factor computing unit for, when external temperature information is input through the data input unit, computing load factors by time according to the input external temperature information; a refrigeration load amount computing unit for computing the refrigeration load amount to be consumed for a corresponding time zone by using the load factor computed by the load factor computing unit; an operating refrigerator selecting unit for determining the minimum number of operating refrigerators capable of generating the refrigeration load amount or more at the lowest cost, in consideration of the refrigeration load amount computed by the refrigeration load amount computing unit and the consumption costs for each refrigerator, which is computed by the unit cost computing unit; a refrigerator operating unit for operating the refrigerators, which are selected by the operating refrigerator selecting unit, at the corresponding time zones. Here, the operating refrigerator selecting unit determines the operating time of ice storage heat through the inverse estimation algorithm of the ice storage heat.
