ResumoP-T-X data for nine combinations of R22-absorbent solutions are presented as correlations. A comparative study of these working fluids in absorption refrigeration systems is made. Based on cut-off temperature and circulation ratio considerations DMEDEG, DMETEG, DMETrEG, DMF and DMA are preferable solvents for R22. Among these R22-DMF and R22-DMA stand out when the criterion of coefficient of performance is also included. The generator cut-off temperatures are correlated in terms of temperatures of absorber, condenser and evaporator.
