Title: Improvements in or relating to refrigerating apparatus
IPC: F25C1/06
Filed: 1950-05-01
Abstract: 671,777. Ice-making. VOGT MACHINE CO.. H. May 1, 1950 [May 26, 1949], No. 10687/50. Class 29 In a tube-ice machine comprising an evaporator 1 and vertical ice-forming tubes 2 having their lower ends proj ecting below the evaporator, the ice-tubes being harvested by reversing the refrigerating machine and heat being applied to the tube ends to prevent ice formation in these ends, the heat supply to the tube ends is provided by warm refrigerant under pressure in either the gaseous or liquid state. In Fig. 1, the tube ends are enclosed in a casing 5, through which passes hot liquid refrigerant passing from the condenser to the evaporator during the freezing phase. Alternatively this casing is traversed during the thawing phase only by hot gaseous refrigerant passing from the compressor to the evaporator. In a further arrangement wherein heat is applied during both the freezing and thawing phases, some of the gaseous refrigerant from the compressor passes through the casing 5 and flows therefrom to the condenser. In a modification, Fig. 6, the heating medium passes through a coil 38 contacting the tubes 2 and within the evaporator, cold being prevented from reaching the coil 38 by insulation 39. In another arrangement of this modification, the coil 38 is outside the evaporator and is spaced from the bottom thereof by the insulation 39, which may, however, be dispensed with. The invention is also applicable to ice-making machines in which the cold is produced by absorption refrigerating systems.
