Performance of single-stage absorption lithium bromide refrigerating machine at boiling points below О °С
Annotation
The use of lithium bromide aqueous solution of low salt concentration as a cooling medium in absorption lithium bromide refrigerating machines allows boiling points below 0 °Сthat enlarges the field of application for these machines greatly. On the basis of extrapolated experimental data from various sources the values of aqueous tension for lithium bromide solution of low concentration are calculated at temperatures below 0 °С. The analysis of energy efficiency for single-stage absorption lithium bromide refrigerating machine at negative boiling point of the cooling medium in evaporator is carried out. The graphs for the dependencies between coefficient of performance and the wide range of external heat source parameters are given.
