Abstract

243,492. Park, J. Oct. 14, 1924. Refrigerating, compression machines for.-In machines operating on the multiple-effect system, the vapour resulting from the primary evaporation is caused to flow as inducing-fluid through an injector or jet pump and thus inject the lowpressure vapour from the main evaporator into the compressor. The refrigerant compressed in a compressor a passes to a condenser b and then through an expansion valve c to the multipleeffect receiver d. The liquid from the bottom of the latter undergoes further expansion in the main evaporator j, while the higher pressure vapour passes by the pipe f through the central converging nozzle k of an injector l and induces' the flow of vapour from the evaporator j into the annular space n and thence by the divergent nozzle o into the compressor. Alternatively the high-pressure vapour may be admitted to the space n and the low-pressure vapour through the nozzle k. A coil immersed in brine or other liquid to be cooled may be introduced between the valve c and the receiver d, or instead of using a receiver a part of the refrigerant may be evaporated in a chamber around the pipe leading to the main expansion valve.
