Abstract:
Disclosed is a refrigerator, comprising an absorber (20), an air compressor (30) and a nitrogen storage tank (50). The storage compartment of the refrigerator is internally provided with a sealed storage space (11). The absorber (20) is disposed inside the storage compartment and is internally provided with a carbon molecule sieve. The air compressor (30) is directly connected to the absorber (20) via an intake pipe (40), and is configured to supply compressed air to the absorber (20) in a controlled manner so that the carbon molecule sieve uses the compressed air to generate nitrogen. An air intake end of the nitrogen storage tank (50) is connected to an absorber (20), and an air outlet end thereof communicates with the storage space (11). The refrigerator reduces the oxygen content in the storage space (11), and the performance of the refrigerator in keeping items fresh is improved.
