Abstract
An air separation device and a refrigerating and freezing device. The air separation device comprises a support frame and an air separation membrane, wherein a supporting surface with a channel and an enriched-gas collection chamber communicated with the channel are formed in the support frame. The air separation membrane laid on the support surface of the support frame and configured to enable more of a specific gas than other gases in airflow of the space around the air separation device to enter the enriched-gas collection chamber through the air separation membrane. According to the air separation device provided by the present invention, the support frame is specially designed to adopt the structure provided with the support surface and the enriched-gas collection chamber, the channel communicated with the enriched-gas collection chamber is formed on the support surface, and the air separation membrane is disposed on the support surface.
