<p>METHODS AND APPARATUS FOR PRODUCING REFRIGERATION Refrigeration is produced by passing liquid carbon dioxide through a narrow slot into an enclosure or conduit having an inlet and an outlet in communication with ambient atmosphere. Liquid carbon dioxide is converted to solid and gaseous phases upon passage through the slot to produce a refrigeration effect and such phases are directed toward the enclosure exit thereby entraining ambient atmosphere in the solid and gaseous stream. This entrainment and mixing is effective to cause a relatively rapid sublimation of the solid carbon dioxide after exiting the enclosure and thus permits uniform refrigeration of a chamber into which the solid and gaseous carbon dioxide is discharged.</p> |
