Excerpt from Refrigerating and Ice-Making Machinery: A Descriptive Treatise for Use of Persons Employing Refrigerating and Ice-Making Installations, and Others The subject of the present volume is one which ought to be of interest to a very large number of readers, inasmuch as machinery and apparatus for the production of cold by artificial means, in addition to its more legitimate uses for ice-making and the preservation of provisions of a perishable nature, is now employed, and plays an important part, in many industries and manufactures. Notwithstanding this, however, with the exception of the scattered information comprised in the few interesting and valuable papers which have been contributed from time to time to the engineering and other institutions and societies, and of the able descriptive articles which have appeared in the leading technical journals at more or less wide intervals, but little has been written treating generally of machinery of this class. The author is, therefore, led to hope that a treatise dealing with the machinery and apparatus used in the principal systems of refrigerating and ice-making will prove not unuseful both to those employing, or intending to employ, and to those in charge of such machinery and apparatus, and to others who, whilst desiring to obtain information upon the subject, have neither the opportunity nor the facility for attaining it from the sources above referred to.
