Refrigeration and freezing equipment

Abstract

The invention provides refrigeration and freezing equipment, comprising a box body, a door body, and a gas regulating membrane assembly, wherein a storage space is limited in the box body; a storage container is arranged in the storage space; a fresh-keeping space is limited in the storage container; the door body is arranged on the front surface of the box body so as to seal the storage space; the gas regulating membrane assembly is installed on the storage container and the surrounding space of the gas regulating membrane assembly communicates with the fresh-keeping space; the gas regulatingmembrane assembly comprises a proton exchange membrane and a hydrogen production device; the gas regulating membrane assembly is configured to make hydrogen generated by the hydrogen production device flow to the proton exchange membrane and react with oxygen in the fresh-keeping space after being decomposed into hydrogen ions and electrons so as to reduce the oxygen concentration in the fresh-keeping space, and the hydrogen production device generates hydrogen by electrolyzing a potassium hydroxide solution. The refrigeration and freezing equipment provided by the invention can effectively reduce the whole energy consumption of the deoxidization process, rapidly reduce the oxygen concentration in the fresh-keeping space, and greatly improve the deoxidization efficiency.

Description

technical field [0001] The invention relates to the field of item storage, in particular to a refrigeration and freezing device. Background technique [0002] With the development of society and the improvement of people's living standards, and people's pace of life is getting faster and faster, people often buy a large number of items placed in various refrigeration and freezing equipment, but for leafy vegetables and melon and fruit foods, refrigeration and freezing The low temperatures in the appliance's storage space not only wrinkle and blotch the skin of these foods, but also affect their original taste and nutrition. [0003] In the fresh-keeping technology of refrigeration and freezing equipment, oxygen is closely related to the oxidation and respiration of food in refrigeration and freezing equipment. The slower the respiration of the food, the lower the oxidation of the food and the longer the preservation time. Reducing the oxygen content in the air has an obvio...

Problems solved by technology

However, the deoxygenation speed of these traditional modified atmosphere preservation schemes is too slow. Generally, it takes at least 20 minutes for the oxygen concentration in a 30-liter container to drop to 15%.

In addition, the above-mentioned traditional controlled atmosphere fresh-keeping solution often consumes a lot of power and loses a lot of energy during the deoxygenation process due to the process of converting electrical energy into kinetic energy or chemical energy.
