In the technical solution of the embodiment of the present application, by arranging the cold storage module 300 in the cold storage 10, the cold storage module 300 includes a plurality of cold storage boxes 310; the cold accumulation box 310 is filled with a phase change material. The real-time temperature control of the refrigerating apparatus 100 in the peak electricity, valley electricity and flat electricity periods by the control apparatus 200 operates at different refrigerating capacities in the peak electricity, valley electricity and flat electricity periods; the refrigerating capacity corresponding to peak electricity is minimum, and the refrigerating capacity corresponding to valley electricity is maximum; when the refrigeration equipment 100 operates in the valley period to provide a larger second refrigeration capacity, maintaining the low-temperature environment of the refrigeration house 10, and simultaneously, the redundant refrigeration capacity is absorbed by the phase change material to store cold, and the refrigeration house 10 enters a cold storage mode for maintaining the low-temperature environment; when the refrigerating apparatus 100 is operated at the flat electric period to provide the third refrigerating amount smaller than the second refrigerating amount, the refrigerating apparatus 100 provides less cold, and the refrigerator 10 enters the maintaining mode to maintain the low temperature environment; when the refrigerating apparatus 100 operates at a smaller refrigerating capacity or provides 0 cold capacity during the peak power period, the phase change material may release cold capacity to the refrigerator 10, and the refrigerator 10 enters a cool releasing mode maintaining a low temperature environment. Therefore, the technical scheme provided by the embodiment of the application can control peak staggering power consumption of the refrigeration house 10, reduce electric energy loss, improve the utilization rate of cold energy provided by the refrigeration equipment 100, and realize energy conservation and emission reduction.
