Abstract
1,230,419. Refrigerating. N. V. PHILIPS GLOEILAMPENFABRIEKEN. 24 July, 1968 [27 July, 1967], No. 35367/68. Heading F4H. In a refrigeration or gas liquefaction system of the type in which high-pressure fluid is cooled to below its inversion temperature and supplied to the jet nozzle of an ejector whose suction inlet is connected to a low-pressure reservoir, the temperature of the cooled highpressure fluid prior to its entry into the nozzle is adjusted so that the enthalpy of the fluid is substantially that given by the constant enthalpy curve which is tangential to the boundary of the liquid-vapour region of the temperature-entropy diagram for that fluid. As shown, helium from a compressor 1 is cooled in heat exchangers 3, 7, 10 in counterflow with low-pressure helium and in heat exchangers 5, 8 by cold gas refrigerators 6, 9. A valve 11 directs the cooled high-pressure helium through a heating path 12 and a cooling path 12 in such proportions that the desired temperature is achieved when the streams are recombined at 14. Path 12 is electrically heated or connected by a copper strap to a higher temperature part of the system, while path 13 includes a heat exchanger 25 immersed in liquid helium in a reservoir 19. The recombined stream is supplied to the nozzle 15 of ejector 16 whose outlet is connected to reservoir 19. Helium vapour returns to the inlet of the compressor from reservoir 19 while liquid helium passes via a throttle 22 to a reservoir 23 which is connected by line 24 to the suction inlet of the ejector. In a first modification the cooled high-pressure helium passes sequentially through the heat exchanger in reservoir 19 and the heating device (Fig. 3, not shown) while in a further modification (Fig. 4, not shown) the heating device is omitted and a regulable part of the helium is tapped off from heat exchanger 8 or 10 or a point therebetween and recombined with the part which has passed through reservoir 19.
