Not illustrated. 1908 edition. Excerpt: ...refrigerator remains to be spoken of, the highly important type which uses carbonic acid as working substance. Carbonic acid machines were patented by Raydt in 1881, and by Windhausen in 1886. It is proper to mention that Professor Linde was one of the first, if not the very first, to introduce carbonic acid practically as a medium of refrigeration. In 1882 he supplied to Krupp's firm, at Essen, a carbonic acid machine, but he preferred ammonia on thermodynamic and other grounds. The carbonic acid machine is particularly associated with the name of Windhausen. His patents were taken up in England by Messrs J. and E. Hall of Dartford, who have successfully faced the difficult mechanical problems involved in compressing, condensing and re-evaporating, without serious loss, a substance which reaches a pressure of over 1000 lbs. on the square inch in the high-pressure side of the apparatus. Thanks in great measure to good constructive features introduced by Mr E. Hesketh and the late Mr A. Marcet of that firm, the carbonic acid machine has become in Messrs Hall's hands a thoroughly practical means of refrigeration. It is specially suitable for use on board ship on account both of its compactness and of the comparative harmlessness of carbonic acid should leakage take place. The high pressures make it necessary to adopt arrangements which are considerably different from those adopted in ammonia machines. Figs. 36 and 36 a give sectional views of the cylinder of a small double-acting carbonic acid compressor by Messrs Hall. Fig. 36 is a longitudinal section showing the piston, the gland, and the two delivery valves. Fig. 36 a, which is reproduced here on a somewhat larger scale, is a transverse section showing the suction valve as well as the...
