Abstract
695,857. Refrigerating. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 8, 1952 [April 11, 1951], No. 8940/52. Class 29 In refrigerators operating on the reversed hot gas engine principle, in which the hot space 7 communicates with the cold space 11 by way of a freezer 8, a regenerator 9, and a cooler 10 the regenerator has a thermal capacity equal to fk/k-1.P mean/Tw B1/B2 where f is a constant and exceeds 0.08, P mean is the mean pressure of the gas in the cycle, and is at least three atmospheres, B1 is the mean total volume in which the cycle takes place, B2 is the mean total volume reduced to the higher temperature, Tw is the absolute temperature of the gas entering the cold space and k is the ratio between the specific heats of the gas at constant pressure and constant volume at the means of the temperatures of the hot and cold spaces. The regenerator is of wire of diameter less than 0.5 mm. A coil 12 arranged around the freezer 8 communicates in a closed circuit with a coil 13 in a cooling chamber 14 and pentane is circulated through the coils by a pump 15.
