  • Absorption refrigerator
    Patent number: 6536229
    Abstract: 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-temp
