Moisture fromthe atmosphere of the room rapidly condenses on the outside of the pipes, andprovision must be made for removal of the dri^D. The atmosphere of the roomrapidly becomes dry. 650. Cold Storage. For preserving vegetables, fruits, poultry, eggs, butter,milk, cheese, fish, meats, etc., either in permanent storage or during transporta-tion, mechanical refrigeration has been widely applied. Temperatures of from25° to 40° F. are usually maintained, the temperature being lowered gradually.Some substances keep best when actually frozen. Mechanically cooled refrigera-tor cars have been described by Miller (9). For all storage-room applications,the fundamental principles underlying the computation of the amount and dis- 478 APPLIED THERMODYNAMICS K\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\^^^^ AWWWWN /r^ ^ ^d^ a- S\\\\\\\\\\\\\\\\\\\\\\\\\W Viry

Reference should be made to the works of Siebel (10) andWallis-Tayler (11). The thorough insulation of the rooms and of the conduct-ing pipes is of much importance. 651. Other Applications. Mechanical refrigeration is universally employed inbreweries, for cooling of the cellars and the wort, as well as for cooling duringfermentation (attemperator system) (12). It is popular in marine service, wherethe sj)ace occupied by stored ice, and its shrinkage, would be serious items ofexpense. It is applied in candy factories, for cooling chocolate; in candle andparaffin works and linseed-oil refi.neries for precipitating out solid waxes frommixtures; in dairies for cooling the milk; in tea warehoiises, dynamite factories,in the manufacture of photographic dry plates, in wine cellars, soda-wa
