The performance of an absorption heat pump (AHP) operating with ammonia-water and ammoniawater- 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 a significantly lower water content with the ternary system, as predicted in the literature.
