เนื้อหาย่อ : THis BooK was first published in 1948 with a two-fold purpose: first, to serve primarily as a college text for senior and graduat for use as a reference by the practicing engineer. The gratifying suecess te study and second of the first edition has spurred the authors to prepare this revision. The theoretical portions of the text assume that the reader has studied physics and mathemat ties, and one chapter contains a review of basic thermo- dynamios. Several chapters, however, are devoted primarily to refriger- ation applieations and to understand them does not require an extensive sheoretieal background. As a text, the book is designed for & comprehensive course in refrigera- tion and air conditioning. adapted to elementary combination courses in refrigeration and air eo ning, in which case portions of the text on advanced refrigeration topics may may be omitted if time is limited. It may also be used for courses in refrigeration, where the air eonditioning.

These three Following this, a review of chapters may be considered as an introduction to the main portions of the text. The authors recognize that because of the necessarily broad scope of the subject matter which must be contained in a text on refrigeration, the order of chapter arrangement may not be completely agreeable to all instruetors. A specife attempt has been made not to segregate theory, application, and equipment into separate sections. Therefore, descrip- tive material on equipment follows closely aiter the presentation of theory applied to such equipment. Speeialized advanced topics of refrigeration are placed toward the end of the text, and the chapters on applications are placdd at the very end. For those woa tl แดล r re develop-
