Abstract
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.
