APPARATUS AND METHOD FOR CONTROLLING THE TEMPERATURE OF A CRYOGEN

摘要

A FLUID SPRAY DEVICE SYSTEM (1) THAT MAINTAINS A RESULTANT FLUID DISCHARGE, OR A MATERIAL ONTO WHICH THE RESULTANT FLUID IS DISCHARGED, WITHIN A PREDETERMINED RANGE OF A SET-POINT TEMPERATURE BY REGULATING THE FLOW RATE OF A THROTTLING GAS USING A PROPORTIONAL VALVE (22). THE RESULTANT FLUID HAS THROTTLING GAS AND CRYOGENIC FLUID COMPONENTS. BOTH THE THROTTLING GAS AND CRYOGENIC FLUID ARE PREFERABLY SUPPLIED FROM A SINGLE TANK (11) AND THE CRYOGENIC FLUID SUPPLY IS PRESSURE-REGULATED AND INCLUDES A TRIAXIAL DELIVERY HOSE (33) HAVING A RETURN LINE WITH A BACK-PRESSURE REGULATOR (54).
