摘要： The evaporator of tubular form of a diffusion-absorption type refrigerating machine has an inlet part closed off from the outside and an outlet part contiguously joined to the tubular outer wall of heat-exchanger and discharges vaporized ammonia as a refrigerant through the heat exchanger to a liquid receiver, and a tube for conducting hydrogen gas as an auxiliary gas from the top of the absorber and another tube of smaller diameter for conducting liquid ammonia from the condenser extend, either side-by-side or with the tube of smaller diameter within the other tube, through the interiors of the heat exchanger and evaporator to the inlet part, where both tubes are open-ended and discharge their respective hydrogen gas and ammonia into the interior of the evaporator at its inlet end.
