Title:
COOLING DEVICE, OPERATION METHOD FOR COOLING DEVICE, AND CONTROL SYSTEM FOR COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/070256
Kind Code:
A1
Abstract:
The present disclosure provides a cooling device which, when installed in an area where rapid increases in real power demand are problematic, can contribute to mitigating rapid increases in real power demand. On the basis of the amount of change, over a day, in real power demand, which is obtained by subtracting the amount of power generated by solar power generation equipment from the actual amount of power consumed, a control unit 60 executes, in a preset second time slot which precedes a range in which real power demand rapidly increases, cold storage operation in which a compressor 30 is driven to store cold energy in a cold-storage material 51 during interior cooling. In a first time slot, which comes after the second time slot and is a range in which real power demand rapidly increases, the control unit 60 executes dissipation operation in which a refrigeration fan 23 and a freezer fan 25 are driven to dissipate cold energy stored in the cold-storage material 51, with the compressor 30 in a stopped state.
