Absorption refrigerator

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 pump ( ) 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 also 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 ( ).
