Heat management system and method for cryogenic liquid dispensing systems
Abstract:
A system for dispensing a cryogenic fluid includes a bulk tank containing a supply of cryogenic fluid. A heating circuit includes an intermediate tank and a heating device and has an inlet in fluid communication with the bulk tank and an outlet. A bypass junction is positioned between the bulk tank and the inlet of the heating circuit. A bypass circuit has an inlet in fluid communication with the bypass junction and an outlet so that a portion of cryogenic fluid from the bulk tank flows through the heating circuit and is warmed and a portion flows through the bypass circuit. A mixing junction is in fluid communication with the outlets of the bypass circuit and the heating circuit so that warmed cryogenic fluid from the heating circuit is mixed with cryogenic fluid from the bypass circuit so that the cryogenic fluid is conditioned. A dispensing line is in fluid communication with the mixing junction so that the conditioned cryogenic fluid may be dispensed. Warmed cryogenic fluid remaining in the heating circuit after dispensing is directed to the intermediate tank and used to warm cryogenic fluid directed through the heating circuit.
