Container capable of cold accumulation

Abstract

The present invention relates to a container capable of cold accumulation. The container at least comprises an outer shell, an inner container used for holding a liquid is disposed inside the outer shell, a refrigeration structure used for generating a refrigerating capacity and a cold accumulation structure for accumulating the refrigerating capacity are disposed at the periphery of the inner container, the inner container has a rapid heat transfer function, the refrigeration structure has a refrigerating capacity for lowering the liquid to be at a temperature suitable for storage, and the cold accumulation structure has a cold accumulation capacitor for maintaining, for a long time, the liquid temperature to be within a temperature range suitable for storage under the condition that the refrigerating structure stops to refrigerate. The cold accumulation structure can absorb part of the refrigerating capacity of an evaporator thus to fully utilize the refrigerating capacity produced by compressor refrigeration, thereby avoiding losses of the refrigerating capacity; and after a compressor stops working, the cold accumulation structure continues thermal insulation and refrigeration of the internal liquid, and the storage and fresh-keeping time can be long.

Description

technical field [0001] The invention relates to the field of refrigeration and cold storage, in particular to a cold storage container. Background technique [0002] At present, in the refrigeration products of freezers and refrigerators, during the cooling process of the refrigeration system, the cooling capacity of the internal compartments is also continuously lost. Therefore, in order to ensure that the temperature of the internal compartments is stable within the required range, the refrigeration system must continue or It is intermittent operation to supplement the lost cooling capacity, and the quality of product insulation directly affects the energy consumption level of the product. In some developing countries or regions where power outages are frequent, in order to avoid food deterioration during power outages, there is a higher requirement for the insulation effect of the product. [0003] Under normal circumstances, refrigeration products generally improve the ...

AI Technical Summary

Problems solved by technology

[0003] Under normal circumstances, refrigeration products generally improve the insulation effect by using better insulation materials, appropriate foam density, and increasing the thickness of the insulation layer. However, these solutions are limited by the cost of insulation materials, product size and volume requirements. In the medical field with high temperature control and heat preservation requirements, there are also cold storage devices to improve the heat preservation effect of products, but generally double-layer inner tanks are used. This structure not only greatly reduces the effective volume of the product, but also has complex manufacturing processes and costs. The rise is relatively large, and it cannot be promoted in the civilian field, and the above-mentioned products cannot directly hold and cool liquids
