摘要：An air-cooled double-effect salt solution absorption refrigeration machine having high and low pressure generator stages is operated with a lower pressure in the evaporator than in the absorber. This achieves a desired low evaporator temperature while permitting the absorber to u an absorbent salt solution having a lower salt concentration and hence a lower crystallization temperature than would otherwi be necessary for the same cooling effect. In order to maintain the pressure differential between the evaporator and the absorber the vapor from the evaporator is compresd to absorber pressure before passing to the absorber. The compression is effected with an ejector device which employs refrigerant vapor flowing from the lower pressure generator stage as the driving fluid.
