摘要：

This paper compares the theoretical performance of the modelling of a heat pump system for cooling and heating operating with water/lithium bromide and an alternative aqueous ternary hydroxide mixture. The aqueous ternary hydroxide working fluid consists of sodium, potassium and caesium hydroxides in the proportions 40:36:24 (NaOH:KOH:CsOH). Plots of Carnot coefficients of performance and enthalpy based coefficients of performance are shown against the most important temperatures of the system. The results showed that similar coefficients of performance are obtained for both mixtures; however, it was found that the system operating with the alternative mixture may operate with a higher range of condenser and absorber temperatures and the heat delivered by these components can be easily removed by air.
