ABSORPTION REFRIGERATING MACHINE

摘要

A steam type absorption refrigerator which circulates absorption fluid from an absorber(1), through a low-temperature heat exchanger(3), a low -temperature regenerator(4), a high-temperature heat exchanger(6), a steam heating type high-temperature regenerator(7), the high-temperature heat exchanger(6) and the low-temperature heat exchanger(3) in order, back to the absorber(1) comprising, a fluid concentrating boiler(10) which is disposed between the high-temperature regenerator(7) and the high-temperature heat exchanger(6) concentrating the absorption fluid under heat, and a pump(13) which extracts a part or all of the concentrated absorption fluid from the high-temperature regenerator(7) and feeds it to the fluid concentrating boiler(10), wherein the fluid concentrating boiler is connected to the high-temperature heat exchanger (6) so that the absorption fluid concentrated under heat is returned to the heating side of the high-temperature heat exchanger(6) and is also connected to the high-temperature regenerator(7) so that refrigerant steam generated from the absorption fluid at the fluid concentrating boiler is fed as a heating source to the high-temperature regenerator (7). <IMAGE>
