FIELD: heating.
SUBSTANCE: autonomous absorption refrigerator without moving units with a liquid absorbent comprises a generator with a source of heating of a coolant solution, a condenser, an absorber, an evaporator made as a closed reservoir, a thermal siphon with the source of heating, serially joined with a closed pipeline. The generator is equipped with additional sources of heating, one of which is solar radiation. The absorber is coupled with the evaporator by means of row of heat-insulated tubes distributed on the absorber and evaporator surface, through which the gaseous coolant arrives from the evaporator into the absorber.
EFFECT: improved efficiency and reduced dimensions of the refrigerator, operating with application of solar energy, higher reliability of the refrigerator in case of temporary power supply interruption, and capability to operate for a long time without power supply in sunny hot regions, even when the night temperature exceeds temperature of the cooled object.
