摘要： Provided is a refrigerating and freezing device. The refrigerating and freezing device comprises a cabinet body with a first storage space defined therein, an oxygen-enriched membrane assembly and an air extraction device. A storage container in which an atmosphere-controlled freshness-keeping space is formed is disposed in the first storage space. The oxygen-enriched membrane assembly is provided with at least one oxygen-enriched membrane and an oxygen-enriched gas collection chamber. The air extraction device is communicated with the oxygen-enriched gas collection chamber through a pipeline to extract and discharge the gas that permeates into the oxygen-enriched gas collection chamber out of the storage container. The refrigerating and freezing device not only has good freshness-keeping performance, but also has relatively low requirements on the rigidity and strength of the storage container. Besides, it is small in size and low in noise, and it is suitable for household and individual use.

摘要： A refrigerator comprises a refrigerator body, an air-conditioning membrane assembly and an air pump assembly. The refrigerator body defines a storage space and a compressor chamber therein, a storage container is arranged in the storage space, and a freshness-keeping space is defined inside the storage container. The air-conditioning membrane assembly is configured to allow more oxygen than nitrogen in airflow in a surrounding space of the air-conditioning membrane assembly to pass through the air-conditioning membrane and enter an oxygen-rich gas collection chamber. An inlet end of the air pump is communicated with the oxygen-rich gas collection chamber in a controlled manner via a pipeline and a pipeline switching mechanism, for pumping gas in the oxygen-rich gas collection chamber to the outside of the freshness-keeping space, such that the actual content of oxygen in the freshness-keeping space is in a range of 2% to 19%.
