ABSTRACT:
A method comprising feeding a liquefied refrigerant selected from the group consisting of 1,1,1,2,3,3,3-heptafluoropropane; 1,1,1,2,2,3,3-heptafluoropropane; 1,1,1,2,2,3-hexafluoropropane; 1,1,1,3,3,3-hexafluoropropane; perfluorobutane; and octafluoropropane into direct contact with a volume of aqueous liquid in an enclosed ice making vessel to convert part of the aqueous liquid to ice crystals, without the formation of a water-refrigerant hydrate, by vaporizing the refrigerant by heat exchange with the aqueous liquid.
