ASHRAE 90439

Abstract

<strong>Preface</strong> <br>The text contains twelve chapters, including three short chapters that review the fundamentals of refrigeration, heat transfer, and psychrometrics. Information from the <em>ASHRAE Handbook&#8212;Fundamentals</em> is summarized and supplemented with items from industry sources. The remaining chapters assemble information from ASHRAE handbooks, standards, manufacturer data, and design procedures commonly used by professional engineers. Topics include equipment selection and specification, comfort and IAQ, building assemblies, heating and cooling loads, air distribution system design, water distribution system design, electrical and control systems, design for energy efficiency, and design for economic value. <br>A suite of complementary spreadsheet programs that incorporate design and computation procedures from the text are provided on the CD that accompanies this book. These programs include psychrometric analysis, equipment selection, heating and cooling load calculation, an electronic "ductulator," piping system design, a ductwork cost calculator, and programs to evaluate building system demand and energy efficiency. Future updates to these programs can be found at www.ashrae.org/updates.
