Abstract
The invention relates especially to a refrigerating device comprising a pressure-resistant container (1) furnished with an adsorbent material (2), which device furthermore comprises an adjustably set valve (7) whose passage communicates, on the one hand, with the inside of the container and, on the other hand, with the outside, and means (5, 6) for bringing said container temporarily into communication with a pressurized source (10, 11) of gas which can be adsorbed by said adsorbent material. Use in refrigerated clothing or portable refrigerators.
Claims16
A method for producing cold, comprising:
- adsorbing pressurized carbon dioxide in an adsorbent material held in a container, and then desorbing said carbon dioxide under a controlled pressure greater than atmospheric pressure, the desorbed carbon dioxide being discharged to atmosphere and said adsorbent material being selected from at least one member of the group consisting of activated carbon fibers and activated charcoals.
A refrigerating device comprising a pressure-resistant container furnished with an adsorbent material selected from at least one member of the group consisting of activated carbon fibers and activated charcoals, which device further comprises an adjustably set valve whose passage communicates, on the one hand, with the inside of the container and, on the other hand, with the outside, said device further comprising means for bringing said container temporarily into communication with a pressurized source of carbon dioxide.
