An air-cooled absorption refrigeration system wherein refrigerant vapor is introduced into a vertical tube absorber at the top and bottom, or top, bottom and center thereof so as to allow the refrigerant vapor to flow into the absorber at different scattered positions whereby a sufficient flow passage area for the refrigerant vapor is smoothly secured and the refrigerant vapor is received by the absorber.

Air-cooled absorption refrigeration system

In a hermetically circulating, absorption type refrigerator based on a closed circulation system of constituent members comprised of a successive communication of a regenerator, a condenser, an evaporator, an absorber and a heat exchanger, refrigeration being produced by repetitions of concentration, refrigerant dilution, and heat exchange of an aqueous concentrated lithium bromide solution sealed in the circulation system, a hydrogen gas generated in the refrigerator is continuously converted to water, condensed and removed or returned to the refrigerator as a refrigerant. The pressure increase in the refrigerator can be prevented, and a high refrigerating performance can be continuously maintained without any special maintenance.
