  • My present invention has for its object to still further improve refrigerating apparatus of last said type, and'more particularly to ensure a still higher lift of the liquor level in the pipe.
  • the lower end of the ascending pipe opens into a' reservoir adapted to be heated and and preferably placed inside the communicating with, boiler, whereas a conduit is provided through which part of' the liquor returning from boiler can be bye-passed to be understood that the wor to be construed in its widest is intended to also include, flare or funnel.
  • the liquid 'in the reservoir will have substantially the same temperatur'e as that in the gasexpeller, but as its concentration, owing to thedirect inflow of rich liquor from the absorber, is much higher, a violent ebullition will take place therein, so that the liquor in the ascending pipe can be lifted to an exceptionally high level. Nevertheless, it is impossible for wet vapours to reach the condenser, since the ascending pipe does not open into the 10 vapour space of the boiler.
  • a separating chamber will be interposed, in a manner known per se, in the conduit between the ascending pipe and the absorber, in order to separate the (wet) refrigerant va- 15 pours from the absorption liquid.
  • the vapour space of said chamber may, in accordance with the invention, be connected with the liquor return pipe before the point of entry of the aforesaid bye-pass.
  • the annexed diagrammatic drawing illustrates, by way of example only, a refrigerating apparatus in accordance with the invention.
  • I. is the boiler, 2 a tube fitted within the boilerand adapted to be heated, for instance, by an electric heating element not shown.
  • the boiler I is connected through a tube 3 with the condenser 4, which in turn communicates'with the evaporator 6 by means of a pipe 5.
  • the evaporator 6 is connected by a tube I with the absorber 8, the lower portion of which is in direct communication with the upper portion of the boiler I. through a conduit 9.
  • This pipe opens into a chamber I2 near the top thereof, a pipe I3 connecting the bottom of said chamber with the upper portion of the absorber B.
  • pipe I3 is, through part ofits length, enclosed by the return pipe 9 so as to forma heat exchanger therewith.
  • the chamber I2 communicates with the return pipe 9 by means of a vapour discharge pipe I4.
  • the return pi e 9 is connected with the lower portion of reservoir I0 through a bye-pass I5 fitted with a valve I6.
  • the aqueous solution of ammonia contained in the boiler I is heated to the required temperature.
  • the ammonia vapours expelled thereby flow through pipe 3 to the condenser l, where they are liquefied.
  • the liquid ammonia flows into thev evaporator 6, where it is again vaporized to produce cold, the vapours being discharged into the absorber 8.
  • the water is at substantially the same level as in the boiler I. Near the top of the absorber, water is introduced through pipe l3. It is tobe understood that, owing to the generation of the vapour bubbles in the liquor contained in boiler I, said liquor will ascend in pipe H so as to reach the separator l2, in which the water collects near the bottom and the ammonia vapour collects in the upper part.
  • the Water is discharged through pipe l3 and supplied, by its own static pressure, to absorber 8, whereas the vapour is fed, by pipe 14, into the conduit 9 through which the rich liquor from the absorber 8 is returned to the boiler I. Said rich liquor is thus still further concentrated, and part thereof is bye-passed through pipe ii to flow directly into the reservoir I0. As this reservoir is directly heated by the tube 2, a relatively great amount of ammonia vapour is generated therein,
  • the separator I2 may be placed at a considerably higher level than the boiler l and the absorber 8 and a strong liquid circulation brought about.
