Abstract
The performance of an absorption heat pump (AHP) operating with ammonia-water and ammonia-water-lithium bromide mixtures is compared. The AHP was designed for the ammonia-water system but operated successfully and without modifications with the ternary system. The pressures and most of the temperatures showed only minor differences. The COP of the AHP operating with a ternary mixture having a LiBr/H20 mass ratio of 0.48/0.52 was, on average, 0.05 lower than with the binary system. However, several factors indicated that the refrigerant vapor entering the rectifier had significantly lower water content with the ternary system, as predicted in the literature.Citation
