Abstract:
A steam type absorption refrigerator which circulates absorption fluid from an absorber, through a low-temperature heat exchanger, a low-temperature regenerator, a high-temperature heat exchanger, a steam heating type high-temperature regenerator, the high-temperature heat exchanger and the low-temperature heat exchanger in order, back to the absorber comprising, a fluid concentrating boiler which is disposed between the high-temperature regenerator and the high-temperature heat exchanger concentrating the absorption fluid under heat and a feed means which extracts a part or all of the concentrated absorption fluid from the high-temperature regenerator and feeds it to the fluid concentrating boiler, wherein the fluid concentrating boiler is connected to the high-temperature heat exchanger so that the absorption fluid concentrated under heat is returned to the heating side of the high-temperature heat exchanger and is connected to the high-temperature regenerator 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.
