Principios de Refrigeracion by Roy J. Dossat: A Review


Principios de Refrigeracion (Principles of Refrigeration) is a book written by Roy J. Dossat, a professor of mechanical engineering at the New Jersey Institute of Technology. The book was first published in 1961 in English, and later translated into Spanish by CompaÃÃa Editorial Continental in 1980[^1^] [^2^]. The book covers the basic principles and applications of refrigeration and refrigerating machinery, such as thermodynamics, heat transfer, refrigerants, compressors, evaporators, condensers, expansion devices, refrigeration cycles, refrigeration systems, and refrigeration controls.


The book is intended for students and professionals who want to learn the fundamentals of refrigeration engineering. The book is organized into 15 chapters, each with its own objectives, summaries, problems, and references. The book also includes numerous diagrams, tables, charts, and examples to illustrate the concepts and calculations. The book is praised for its clear and concise presentation of the theory and practice of refrigeration[^3^] [^4^]. However, some readers may find the book outdated or too technical for their needs.


Principios de Refrigeracion by Roy J. Dossat is a classic and comprehensive reference for anyone interested in the field of refrigeration. The book is available in PDF format online[^1^], or in print from various sources[^2^] [^3^] [^4^]. The book is suitable for both academic and professional purposes, as it provides a solid foundation and a practical guide for refrigeration engineering.Some of the topics that the book covers in more detail are:


The properties and characteristics of various refrigerants, such as ammonia, carbon dioxide, water, and halocarbons. The book explains how to select the appropriate refrigerant for different applications and conditions, and how to handle and store them safely.


The design and operation of different types of compressors, such as reciprocating, rotary, centrifugal, and screw compressors. The book describes the advantages and disadvantages of each type, and how to calculate their performance and efficiency.


The function and classification of evaporators, condensers, and expansion devices. The book discusses the factors that affect the heat transfer and pressure drop in these components, and how to optimize their size and configuration.


The analysis and optimization of refrigeration cycles, such as vapor compression, absorption, gas cycle, and cascade cycles. The book shows how to use thermodynamic diagrams and equations to evaluate the energy balance and coefficient of performance of these cycles.


The design and control of refrigeration systems, such as domestic refrigerators, air conditioners, heat pumps, ice makers, cold storage rooms, and industrial refrigeration plants. The book explains how to select the appropriate system components and layout, and how to use sensors, controllers, valves, and switches to regulate the system operation.


The book also includes appendices that provide useful data and tables for refrigeration engineering, such as refrigerant properties, psychrometric charts, steam tables, unit conversions, and symbols. The book is written in a clear and concise language that is easy to follow and understand. The book is suitable for both beginners and experts in refrigeration engineering. aa16f39245
