Abstract

1,084,736. Refrigerating; thermal regenerators. PETROCARBON DEVELOPMENTS Ltd. April 8, 1964 [April 10, 1963], No. 14351/63. Headings F4H and F4K. A method of producing refrigeration comprises passing gas under pressure through a regenerator 12 and into a tube 10 having a closed end 11, cooling the closed end of the tube and exhausting the gas from the tube via the regenerator to produce refrigeration adjacent the open end of the tulbe. The regenerator 12 communicates via a pipe 20 with a line 21 connected at one end to the outlet 22 and at the other end with the inlet 23 of a compressor 24. Line 21 also includes an after-cooler 25, gasreservoirs 31 and 32, and valves 26 and 28. Initially valve 26 is opened for 0À24 seconds while valve 28 is closed to admit gas to the tube, the closed end of which is cooled by water flowing through a tube 13. After 0À045 seconds from the closure of valve 26 valve 28 is opened while valve 26 remains closed to exhaust the gas from the tube. In flowing out of the tube the gas expands to produce refrigeration adjacent the open end of the tube to cool a pipe 16 through which a fluid to be cooled is circulated. The refrigeration produced may be utilized to cool the end of another tube supplied in parallel with gas from line 21. Thus in Fig. 3 (not shown) two tubes are shown having a common regenerator and further comprising a second regenerator for the second tube while in Fig. 6 (not shown) three tubes, each having a separate regenerator, are provided. The working medium may comprise argon or air and, if the latter, is supplied from a compressed-air source to the tube and exhausted to atmosphere. The pressures and temperatures obtaining in the system are specified together with prefe rred dimensions of the apparatus. The regenerators comprise stainless steel cylinders packed with discs of 200-mesh stainless steel gauze.
