This book has been designed as a reference for the undergraduate and post graduate students of engineering and technology and researchers. It provides a well balanced coverage of concepts, mathematical operations and demonstration within the scope of domestic refrigerator. The book covers the principles necessary for understanding the fundamentals of refrigerator design and analysis along with detail design and analysis procedure. The introduction describes the history and necessity of refrigeration. Second chapter emphasises on research work done by other researchers related to refrigeration and air conditioning specially Capillary Tube Design, Evaporator Design, Testing standards. Subsequent chapters are concerned with fundamentals, design procedures, testing parameters and procedures for domestic refrigerators. A glance of the table of content indicates the wide scope and coverage of this book. Addition to this, in brief uncertainty analysis is discussed in appendix. The aim of this book is to develop in the readers a through appreciation of a wide spectrum of domestic refrigeration design including capillary tube design and evaporator design.
