HIGH TEMPERATURE REGENERATOR FOR ABSORPTION WATER HEATER/CHILLER

WIPO Patent Application WO/1999/024768

A1

A high temperature regenerator for absorption water heater/chiller, in which a diluted solution of lithium bromide is heated and condensed to separate steam, a refrigerant therefrom, wherein a combustion chamber (11B) is defined by an inner tube (2) on the side of a blowout port of a burner (4B) from which a combustion gas is blown out, the solution being held in a liquid chamber extending on the upper and lower sides of the combustion chamber and defined by an outer tube (1), a refrigerant steam outflow passage (8) being formed in an upper portion of the outer tube with gas discharge passages (13, 14) formed at the end portion of the combustion chamber which is on the opposite side of the burner, a plurality of solution pipes (3) providing communication between the liquid chamber portions on the upper and lower sides of the combustion chamber extending through the combustion chamber, the solution pipes being formed of flat pipes having fins (16) on upstream side surfaces alone thereof, heat exchange between the solution with which the flat pipes are filled and combustion gas being facilitated owing to these fins, whereby a flow of the solution is promoted.
