Description

Flexible cold accumulation module for cold storage and cold storage comprising same Technical Field The utility model relates to the technical field of cold storage equipment, in particular to a flexible cold storage module for a cold storage and the cold storage comprising the same. Background The traditional refrigeration house mainly depends on uninterrupted operation of a refrigeration compressor unit, and cold energy is circularly conveyed into the refrigeration house by means of an air cooler, so that a constant low-temperature environment is maintained. However, this mode of operation has significant drawbacks. In the peak period of summer electricity consumption or in the face of unstable power supply during long-distance transportation, the refrigerating efficiency of the refrigerating unit can be drastically reduced, so that the temperature fluctuation in the warehouse is out of control, and the storage safety and quality of cargoes are directly affected. In order to solve the energy consumption problem, the cold accumulation technology gradually enters the field of view of industry, and the core principle is to store the cold energy of the power grid in the low-valley period for use in the peak period. However, the traditional cold accumulation technology adopts a water cold accumulation mode, and the mode has the advantages of large equipment occupation area, limited cold accumulation capacity, small cold accumulation temperature difference, great limitation of application scenes, difficulty in fully playing value in industrial production and serious obstacle in large-scale popularization. The phase change cold accumulation device can fully utilize the electricity in the valley period, and effectively reduce the operation cost of the cold storage. The peak electricity consumption demand can be transferred to the valley period, so that peak clipping and valley filling of the electric load are realized, the electric power resource allocation is optimized, and the peak power supply pressure is relieved. In practical application, the phase change cold accumulation device remarkably improves cold accumulation efficiency and reduces comprehensive operation cost. The cold storage device as described in reference 1: Reference 1 Chinese patent document with publication No. CN216432194U Reference 1 describes a cold storage device and a cold storage house, which includes k×n cold storage units and N air cooling units, where K and N are positive integers. Wherein, a cold accumulation unit includes support frame and a plurality of cold accumulation board. Each cold accumulation plate comprises a shell and cold accumulation substances filled in the shell, the shell is penetrated and provided with assembly holes, and the support frame sequentially penetrates through the assembly holes of the plurality of cold accumulation plates to fix the plurality of cold accumulation plates to form a cold accumulation unit. The air cooling unit is used for blowing air to the cold accumulation plate so as to improve the speed of the cold accumulation plate for accumulating cold or releasing the cold.
