In the peak electricity price period, the refrigerating system stops running, the cold accumulation module releases cold energy, and the cold energy released by the cold accumulation module is reduced in the valley electricity price period, so that the cold accumulation module can still provide enough cold energy to enable the direct current refrigeration device to run at the target temperature in the peak electricity price period, namely when a user frequently uses the direct current refrigeration device, thereby reducing the expenditure of household electricity charge and reducing the influence of the direct current refrigeration device on sleeping of the user.
