Description

Technical Field

[0001] The utility model relates to the technical field of cold storage equipment, in particular to a cold storage plate component for a large cold storage and a cold storage shelf. Background Art

[0002] Cold chain logistics provides suitable temperature and humidity for the storage, transportation and sales of perishable foods, which can greatly reduce the spoilage rate of agricultural products and foods. Cold storage is an important infrastructure for food freezing, processing, storage and circulation. As the scale and number of cold storage will continue to grow rapidly, the high energy consumption of cold storage is an issue that cannot be ignored. The energy consumption of cold storage is composed of cooling energy, fan energy, lighting energy and other aspects, but most of the energy is consumed by the cooling system.

[0003] Phase change materials have great potential for application in cold chains. Cold storage technology is a technology that first stores the cold energy obtained and then releases it when it is needed. It is a regulation and supplement to refrigeration technology. When electricity is at a low point, the refrigerator works to cool. Energy storage materials are used to store this cold energy and then release it during peak electricity periods to alleviate peak electricity consumption and improve energy utilization. Install cold storage plates in the cold storage to store the cold energy. After the refrigeration equipment in the cold storage is shut down, the cold energy is released through the cold storage plates to maintain the low temperature environment in the storage, reduce temperature fluctuations, and better ensure the quality of food in the storage. For example, the technical solution recorded in Reference 1:
