PROCESS FOR PRODUCING COLD AND/OR HEAT BY AN ABSORPTION CYCLE, ESPECIALLY USABLE IN ROOM HEATING

摘要

Cold or heat are produced by an absorption process comprising an absorption step, a desorption step, a rectification step, a condensation step and a vaporization step. The process operates at a lower pressure level and at a higher performance rate than the conventional absorption processes. This result is obtained by condensing the vapor phase from the rectification zone in admixture with a dilute solution of the working fluid and by supplying the absorption solution to an intermediary point of the rectification zone.
