Abstract

The invention relates to a phase-change cold-accumulation chilling and freshness keeping system for a supermarket, and belongs to the technical field of supermarket exhibition devices. A refrigerating system and a cold-accumulation material tray are combined on the phase-change cold-accumulation chilling and freshness keeping system; the problem that the ice using amount of chilled and fresh aquatic products in the selling process is large is solved; the ice consumption amount is reduced while the iced storage and freshness keeping advantages are maintained. According to the phase-change cold-accumulation chilling and freshness keeping system, electricity can be used for refrigeration for accumulating cold for cold-accumulation materials in the cold-accumulation material tray at night, and the refrigeration cost is reduced through peak and valley electric charges at night; in the aquatic product selling process in the day, the ice needed for maintaining the lower temperature is replaced by the cold-accumulation material tray, the ice using amount is greatly reduced, and the electricity and water resources which are used for making ice are saved; energy conservation and environment protection in the chilled and fresh aquatic product selling process are achieved.

Description

technical field [0001] The invention relates to a phase-change cool-storage refrigeration system for supermarkets comprising a refrigeration system and a cool-storage tray. It is used in the display and sales process of chilled aquatic products, and belongs to the technical field of supermarket display equipment. Background technique [0002] With the rapid development of my country's aquaculture industry, ocean fishing industry, aquatic product processing industry, and aquatic product distribution industry, the import of aquatic products has increased year by year, and the status of aquatic products in the people's vegetable basket has gradually increased. In this context, aquatic products have already occupied a pivotal position in the fresh commodities in Beijing supermarkets. Due to the perishable nature of aquatic products, the freshness preservation problem in the sales process of aquatic products has become the primary problem affecting its development. [0003] Amo...
