PURPOSE:To operate the titled refrigerator in an energy saving manner by a method wherein a set value of cold water temperature at which the consumption of energy of a cooling air conditioning system is minimized is operated so that the capacity of the refrigerator is controled. CONSTITUTION:A cold water temperature detector 5 and a load measuring device 6 are provided in a cooling pipe 2 from which cold water prepared by the refrigerator 1 is introduced. The set value Tos of the temperature of the cold water is operated by a cold water set value operating section 10 on the bases of the consumption of energy WR of the refrigerator 1 obtained by a operating section 8 for energy consumption of a refrigerator and the consumption of energy WA of a operating section 9 for energy consumption of a transporting system. Further, a control section 11 controls the opening degree of an adjust valve 4 for adjusting the amount of fuel supply to a high temperature regenerator so that the difference between the cold water temperature set value Tos and the cold water temperature Tm from a cold water temperature detector 5 becomes zero. |
