Summary

A comparative study of different working fluid combinations with R22 as refrigerant and six absorbents, namely, DMF, DMA, NMP, DMEDEG, DMETEG and DMETrEG, in a vapour absorption heat transformer is made. DMA and NMP are preferable solvents for R22 to obtain high heat delivery temperatures, low circulation ratios and high coefficients of performance. It is observed that the cumulative change in enthalpy of mixing at absorber conditions significantly influences the performance of the system.
