Abstract

Disclosed is an oxygen enriched membrane assembly (100), comprising: a support frame (110), wherein the support frame has a first surface (111) and a second surface (112) parallel to each other and is formed with multiple airflow passages (113), the airflow passages respectively extending on the first surface (111) and the second surface (112) and penetrating through the support frame (110) and communicating the first surface (111) and the second surface (112), and the multiple airflow passages (113) together forming an oxygen enriched gas collecting cavity; and two oxygen enriched membrane layers (120) respectively laid on the first surface (111) and the second surface (112) of the support frame (110), each of the oxygen enriched membrane layers (120) being configured to enable much oxygen, with respect to nitrogen gas therein, in an airflow of a space surrounding the oxygen enriched membrane assembly (100) to permeate the oxygen enriched membrane layers (120) so as to enter the oxygen enriched gas collecting cavity.

Description

technical field

[0001] The invention relates to the technical field of gas separation, in particular to an oxygen-enriched membrane module and a refrigerating and freezing device having the same. Background technique

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. With the improvement of the quality of life, consumers have higher and higher requirements for the preservation of stored food, especially for the color and taste of food. Therefore, the stored food should also ensure that the color, taste, and freshness of the food remain unchanged as much as possible during the storage period.

[0003] In the fresh-keeping technology of the refrigerator, oxygen is closely related to the oxidation and respiration of the food in the refrigerator. The slower the respiration of the food, the lower the oxidation of the food and t...
