    Abstract

    This paper presents the theoretical study of a cooling absorption cycle with working fluids exhibiting phase separation. The cycle performance can be calculated if the working fluid Gibbs excess energy, as a function of temperature, pressure and condensation, is known. The Gibbs excess energy function was cast in such a way that the interaction between the two components of the working solution was characterized either by four or by six parameters when the statistical-mechanical-local-composition (SMLC) model was used. The cycle performance was optimized by combination of steepest ascent and random search methods. The results are dependent on the equation of state used. It is shown that coefficients of performance (COP) of 0.6-1.65 may be reachable if suitable fluids can be found.
