摘要： A compact absorption refrigeration unit has a central mounting core containing a generator about which substantially all of the components of the refrigeration system are mounted in a predetermined configuration. The generator has heat transfer fins secured to its surface which have a predetermined configuration that allows the fins and generator to absorb heat at the optimum rate at which heat can be transferred thereto without damage to the fins. The unit also includes an evaporator having a centrally positioned reservoir and a helical passageway providing a flow path for a heat exchange medium and containing a fluted helical heat exchanger tube which provides a countercurrent refrigerant, thereby to chill said heat exchange medium. In one embodiment of the invention the unit is provided with a compact boiler for use in heating the heat exchange medium, thereby permitting the unit to be selectively operated for both heating and cooling.

摘要： An absorption refrigeration system having a gas-fired, infrared radiant heater, a compact single-unit combined generator, analyzer and rectifier. The unit is formed by concentric cylindrical shells closed at the top and bottom to form an annular space therebetween with the inner wall defining the annular space surrounding the radiant burner. The lower section of the annular space constitutes the generator; the intermediate section contains the analyzer and an associated heat exchanger; and the upper section contains the rectifier. The interior wall of the generator section is uniformly heated by the radiant burner, and the products of combustion also heat the exterior wall of the generator.
