Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1906 edition. Excerpt: ... drip pans placed or hung below them, and, generally speaking, the drippings ought to be prevented from entering the fermenting tubs, dripping over meat, vegetables and cold storage goods in general. CIRCULATION AND SWEATING CEILING. The method to create and maintain a dry, pure and constant circulation of air in the rooms and moreover to prevent "sweating ceiling," consisting in constructing one or more insulated false ceilings below the ceiling proper, is also very efficient. The lines of this false ceiling insulation should be carried well down on the sides below the lower lines of the side wall piping, giving the ceiling a pitch from the center of the room downward toward the walls, and leaving a good wide opening in the center of the false ceiling for the admission of the warm air currents, and openings at the bottom of the side insulated fenders, to allow the currents of cold air to flow down freely into the refrigerated chamber. In this manner all of the air will be brought directly in contact with the cooling surface of the piping, the moisture will all be deposited on the piping and the air of the rooms will be dry as well as cold. Sometimes the location of a few lines of cooling pipes on the ceilings will prevent the ceiling condensation materially, as the piping then becomes the condensing surfaces, and the moisture collects and freezes on the pipe surfaces. NUMERICAL RULES FOR MOISTURE. The proper degree of humidity in cold storage rooms, especially also for the storage of eggs (to avoid mold and shrinkage at the same time) is of the utmost importance, and Cooper finds that the relative humidity should differ with the temperature at which the rooms are kept. Thus a room kept at 28 F. should have a relative humidity...show more
