Abstract Single-effect CH3OH-LiI-ZnBr2 and C2H5OH-LiI absorption heat pumps are simulated to evaluate feasibility as heating device. These systems are predicted to give higher heating COPs in wide operating ranges compared to conventional systems. Among the two systems, the C2H5OH-LiI system is found to be more advantageous for operating in extremely cold weather due to the large solubility of Lil in C2H5OH.
