<p>Apparatus and process are disclosed for increasing the efficiency of thermally powered absorption heat pumps which use volatile absorbents. The improvement reduces rectification losses in absorption cycles having at least two generators operating at different pressures. The rectifier (7) for the higher pressure generator (1) is refluxed at least in part by exchanging latent heat (9) between rectifier vapor and absorbent solution at the approximate pressure of the lower pressure generator.</p> |
