    摘要： An absorption refrigerator is characterized by an absorber which has a tube bank of heat-conductive tubes in the absorber, a vapor flow passage between the tube bank and a side wall of the absorber which is opposite to and separated from the tube bank in a radial direction of the heat-conductive tubes by a distance equal to or larger than a maximum pitch of the heat-conductive tubes, at least a baffle plate disposed in the vapor flow passage, and a gas extraction port disposed outside the tube bank. A further arrangement is characterized by an absorber having a tube bank in the absorber, a vapor flow passage between the tube bank and a side wall of the absorber, and a gas extraction port disposed around a central portion of the tube bank.

    摘要： An arrangement of an evaporator, an absorber, a generator and a condensor within a shell of a single effect absorption type refrigerator or a multiple effect absorption type refrigerator, such as a double effect or triple effect type refrigerator. Positioned on opposite sides within the shell are an evaporator and a generator, and disposed therebetween are an absorber and a condensor. This arrangement presents an improved efficiency in terms of space to provide a compact type refrigerator.

    摘要： There is disclosed an absorption refrigerating machine in which evaporators as well as absorbers are arranged in a two-stage manner. A refrigerant, heated by a regenerator, is condensed by a condenser, and then is fed to a first evaporator. The refrigerant, produced in the first evaporator, is absorbed by a first absorber, formed integrally with the first evaporator, and is formed into an intermediate solution, and then is fed to a second absorber. The second absorber comprises a spray absorber which obviates the need for providing a heat-transfer pipe therein. The condensed refrigerant is supplied to a second evaporator, formed integrally with the second absorber, from a refrigerant tank formed at a lower portion of the condenser or at a lower portion of the first evaporator. The refrigerant, fed to the second evaporator, is absorbed by the solution sprayed in a supercooled condition in the second absorber, thereby producing a dilute solution. Part of the dilute solution, raised in temperature by absorbing the refrigerant, is returned to the first evaporator, and exchanges heat with liquid refrigerant, condensed in the condenser, to be cooled. The cooled dilute solution is again sprayed in the second absorber. The dilute solution in the second absorber is kept in a supercooled condition, and therefore the chilled water or brine, flowing through a heat-transfer pipe, provided in the second evaporator, can be kept to a low temperature under 0.degree. C.
