Problems solved by technology

But until now, due to the large size and high cost of nitrogen-generating equipment traditionally used for controlled atmosphere preservation, this technology has basically been limited to use in various large-scale professional storages (storage capacity is generally at least 30 tons or more).
It can be said that what kind of appropriate gas adjustment technology and corresponding devices can be used to economically miniaturize and quiet the air conditioning system, making it suitable for families or individual users, is a problem that technicians in the field of air conditioning and fresh-keeping have been eager to solve but have never been able to solve. Technical problems that can be successfully solved

Embodiment Construction

[0057] figure 1 is a schematic structural diagram of an oxygen-enriched membrane module 100 according to an embodiment of the present invention; figure 2 yes figure 1 A schematic exploded view of the oxygen-enriched membrane module 100 is shown. see figure 1 and figure 2 , the oxygen-enriched membrane module 100 according to the embodiment of the present invention may generally include: a support frame 110 and an oxygen-enriched membrane layer 120 disposed on the support frame 110 .

[0058] In the embodiment of the present invention, the oxygen-enriched film layer 120 may include one or more layers of oxygen-enriched films. Oxygen-enriched membranes are permeable to all gases, but different gases have different degrees of permeability. Gas permeation through the oxygen-enriched membrane is a complicated process, and its mechanism is generally that gas molecules are first adsorbed to the surface of the oxygen-enriched membrane for dissolution, then diffuse in the oxygen...

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...
