A novel type II absorption-cycle heat-pump is described. The proposed cycle utilises the partial miscibility of some binary mixtures to separate the volatile working-fluid from the rich absorbent. The feasibility of the cycle is demonstrated by computer simulation of the cycle using cyclohexane and aniline as working fluids. Simulations demonstrated that useful heating could be achieved only over a limited temperature-range and with poor thermodynamic performance. A modification of this cycle, which included an additional distillation step, was shown to improve performance significantly.
