ABSTRACT:
An absorption refrigeration system utilising a pair of refrigerant fluids one of which constitutes a distillate, the other of which constitutes an absorber, the fluids being separated from one another in a closed circuit, by a distillation process, the more volatile vapor phase (namely the distillate) being condensed to form a liquid phase, expanded, evaporated, and re-absorbed in the less volatile product (namely the absorbent) of the distillation process, each of the refrigerant fluids being a fluoro-carbon compound, the differences of respective boiling points of said pair of fluids being substantially smaller than the corresponding boiling point temperature difference pertaining to the ammonia/water absorption system, the system being characterized in that it is able to operate with a higher temperature cooling medium for the distillation column condenser while utilizing a lower grade of heat in the distillation column re-boiler.
