PURPOSE:To improve the performance of preserving the freshness of vegetables and fruits and provide ease of maintenance by providing an air intake of a nitrogen rich air supply unit in the vicinity of a cold air outlet of a heat exchanger in a refrigerator main body. CONSTITUTION:An air supply compressor 55 draws in and compressed the air on the way along a path 26, that is, the air around a cold air outlet of a heat exchanger 21. When the air comes in contact with the low temperature heat exchanger 21, the moisture in the air condenses and changes into frost on the surface of the heat exchanger 21. Therefore, the air flowing trough the path 26 is dry enough. The air discharged from the air supply compressor 55 is sent to one of packed towers 52a and 52b. As a result, the possibility that the absorbent such as zeolite, activated carbon, etc. absorbs the moisture in the air can be reduced, so that the partial-pressure absorptivity of the absorbent for oxygen and nitrogen is maintained for a long time period. |
