The Compression/Absorption cycle: A high-temperature application
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 1990
A comparison of the performances of a compression/absorption cycle using the two mixtures
NH3/H2O and NH3/H2O-60% LiBr shows an improvement in COP for the ternary working fluid. The improvement, however, is small; for the examples chosen it is about 5%. The advantages of the ternary mixture, such as a lower vapour pressure, a higher heat of vaporization and a reduced specific heat of solution, compared to the binary NH3/H2O, are to a large extent eliminated by the increase of the recirculation flow caused by the addition of salt
Another effect of the increase in solution flow is a change in the location of the optimum operating point for the ternary compared to the binary mixture.
