Method and apparatus for extracting heat from articles with an ebullient liquid freezant

Abstract

Abstract IN AN IMPROVED METHOD, AND APPARATUS, FOR EXTRACTING HEAT FROM ARTICLES BY DIRECTLY CONTACTING THE ARTICLES, IN THE HEAT EXTRACTION ZONE OF AN OPEN VESSEL, WITH AN EBULLIENT LIQUID FREEZANT, WHILE PRODUCING AND MAINTAINING A NON-CONDENSABLE GAS-FREEZANT VAPOR INTERFACE IN THE VESSEL BY MEANS OF A VAPOR CONDENSING MEANS IN THE VESSEL, SAID CONDENSING MEANS BEING OPERATED AT A TEMPERATURE BELOW THE NORMAL BOILING POINT OF THE FREEZANT, THE LEVEL OF THE INTERFACE BEING BELOW THE LEVEL OF ALL PATHS TO THE CLES COME IN DIRECT CONTACT WITH THE LIQUID FREEZANT, SAID ARTICLES BEING INTRODUCED INTO AND REMOVED FROM THE VESSEL WITHOUT SUBSTANTIALLY DISTURBING THE INTERFACE AND WITHOUT INTRODUCING ANY SIGNIFICANT AMOUNT OF NON-CONDENSABLE GAS BELOW THE INTERFACE, THE IMPROVEMENT COMPRISING, WHILE UTILIZING A SUITABLE APPARATUS, PRODUCING AND MAINTAINING INTERFACES IN THE HEAT EXTRACTION ZONE AND IN AN ADJACENT, VAPOR COMMUNICATING, VAPOR CONDENSING ZONE OF THE VESSEL BY MEANS OF A VAPOR CONDENSING MEANS LOCATED IN THE VAPOR CONDENSING ZONE, CONDENSING SUBSTANTIALLY ALL THE FREEZANT VAPOR GENERATED IN THE HEAT EXTRACTION ZONE AND COMMUNICATED TO THE VAPOR CONDENSING ZONE, AND RECYCLING CONDENSED FREEZANT FROM THE VAPOR CONDENSING ZONE TO THE HEAT EXTRACTION ZONE.
