REFRIGERATOR Russian patent published in 2020 - IPC F25D11/00 

FIELD: refrigerating and freezing equipment.

SUBSTANCE: present invention proposes a refrigerator containing: adsorber (20), air compressor (30) and reservoir (50) for nitrogen storage. Tight space (11) for storage of products is formed in compartment for storage of refrigerator products. Adsorber (20) with carbon molecular sieves, located in it, is located in compartment for products storage. Air compressor (30) is directly connected to adsorber via air supply tube and is intended for supply of compressed air for adsorber in controlled way so that carbon molecular sieves are able to prepare nitrogen by means of compressed air. End of gas inlet of nitrogen storage tank (50) is connected to adsorber (20) and its end of gas outlet communicates with space (11) for storage of products. Content of oxygen in product storage space (11) is reduced.

EFFECT: thus, efficiency of freshness preservation in refrigerator improves.
