    • 516,538. Refrigerating. ELECTROLUX, Ltd. June 27, 1938, No. 19046. Convention date, June 25, 1937. [Class 29] Absorpiion systems.-In continuous - cycle systems having a low pressure generator 12 heated by condensation of vapour from a high pressure generator 11, with condensate from both generators flowing to an evaporator 28, a liquid column 13 between the generator parts maintains the difference of pressure between them. The high pressure part of the generator is heated by a gas burner &c. 17, and vapour expelled therein is condensed in a coil 14, the heat of condensation serving as a source of heat of the low pressure part. Condensate from coil 14 flows through a U-seal 16 and pipe 42 to the evaporator, and the expelled vapour from the 'upper part 12 of the generator is condensed at 36 and led into a receiver 39 and thence to the evaporator by a seal 41. The liquid column 13 and seal 41 together balance the seal 16. The refrigerant liquid is circulated by a pump 31 through a coil 33 for cooling air circulated by a fan 35, and is sprayed at 29 into the evaporator. Vapour returns by a conduit 51 to the absorber 18 whence strong liquor flows by conduits 24, 25, 26 to the lower pressure generator 12. The liquid overflows through conduit 13 to the lower vessel 11, whence weak liquor is withdrawn by a conduit 21 with pump 22 and delivered to a spray 20 in the absorber, which is cooled by a water coil 19. A vacuum pump 49 may be connected to the absorber to discharge non - condensible gases and to maintain the system under reduced pressure. Water may be used as refrigerant and potassium hydroxide, lithium chloride or the like as absorbent.
