Abstract

1468539 Refrigerating PHILIPS GLOEILAMPENFABRIEKEN NV 5 April 1974 [9 April 1973] 15129/74 Heading F4H A refrigerating system for cooling a plurality of storage containers 17 comprises low and high pressure compressors 1, 2, heat exchange means 4, 7, 10 for cooling the cooling fluid in the system to a temperature below the inversion temperature of the fluid, a throttle valve 12, and heat exchange coils 16 located in each vessel. Each coil inlet pipe 14 includes a flow restriction 22, the restrictions being of substantially equal cross-sectional area. The system also includes a container 20 wherein the cooling fluid from the throttle valve 12 condenses before passing to the heat exchangers 16. The gas/liquid mixture issuing from the coils 16 is separated into gas and liquid in the container 20. The cooling fluid may be helium.
