Abstract
The present invention provides a refrigerator, comprising: an adsorption container, an air compressor and a nitrogen storage tank. A sealed storage space is formed in a storage compartment of the refrigerator. The adsorption container with carbon molecular sieves disposed therein is disposed in the storage compartment. The air compressor is directly connected to the adsorption container through an air inlet pipe and configured to supply compressed air for the adsorption container in a controlled manner so as to allow the carbon molecular sieves to prepare nitrogen by means of the compressed air. A gas inlet end of the nitrogen storage tank is connected to the adsorption container, and a gas outlet end thereof is communicated with the storage space.
