Estuda-se, desta forma, a possibilidade do uso do ciclo de refrigeração por absorção em veículos automotores paracondicionamento de ar. O ciclo de absorção utilizaria, como fonte térmica, os gases de exaustão ou a água de refrigeração do motor. Esta fonte de calor está disponível, geralmente, em condições variáveis de temperatura e potência. O trabalho foi dividido em três etapas. Na primeira delas é analisado o desempenho do ciclo de absorção funcionando com uma resistência elétrica de potência variável. Nesta etapa os parâmetros do ciclo foram determinados, assim como as temperaturas em diversos pontos do sistema. Na segunda etapa, foi utilizado um soprador térmico que simula os gases de exaustão de um motor a combustão interna. Na eventualidade da utilização do ciclo para o condicionamento de ar em aplicações automotivas, o uso dos gases de exaustão do motor de combustão interna reduziria o consumo de combustível do veículo, visto que o ciclo de absorção não exige potência mecânica do motor, tal como no ciclo tradicional de compressão de vapor. Há vantagens, também, nos itens relativos a manutenção eimpacto ambiental. Como a carga e velocidade de um motor são variáveis, as temperaturas do ciclo sofrem variações muito rápidas. Tal problema foi minimizado com o uso de um regenerador estático, na terceira fase do trabalho, que impõe uma inércia térmica ao sistema, atenuando, desta forma, estas oscilações de temperatura.

Available in PDF, EPUB and Kindle. Book excerpt: The definitive text/reference for students, researchers and practicing engineers This book provides comprehensive coverage on refrigeration systems and applications, ranging from the fundamental principles of thermodynamics to food cooling applications for a wide range of sectoral utilizations. Energy and exergy analyses as well as performance assessments through energy and exergy efficiencies and energetic and exergetic coefficients of performance are explored, and numerous analysis techniques, models, correlations and procedures are introduced with examples and case studies. There are specific sections allocated to environmental impact assessment and sustainable development studies. Also featured are discussions of important recent developments in the field, including those stemming from the author’s pioneering research. Refrigeration is a uniquely positioned multi-disciplinary field encompassing mechanical, chemical, industrial and food engineering, as well as chemistry. Its wide-ranging applications mean that the industry plays a key role in national and international economies. And it continues to be an area of active research, much of it focusing on making the technology as environmentally friendly and sustainable as possible without compromising cost efficiency and effectiveness. This substantially updated and revised edition of the classic text/reference now features two new chapters devoted to renewable-energy-based integrated refrigeration systems and environmental impact/sustainability assessment. All examples and chapter-end problems have been updated as have conversion factors and the thermophysical properties of an array of materials. Provides a solid foundation in the fundamental principles and the practical applications of refrigeration technologies Examines fundamental aspects of thermodynamics, refrigerants, as well as energy and exergy analyses and energy and exergy based performance assessment criteria and approaches Introduces environmental impact assessment methods and sustainability evaluation of refrigeration systems and applications Covers basic and advanced (and hence integrated) refrigeration cycles and systems, as well as a range of novel applications Discusses crucial industrial, technical and operational problems, as well as new performance improvement techniques and tools for better design and analysis Features clear explanations, numerous chapter-end problems and worked-out examples Refrigeration Systems and Applications, Third Edition is an indispensable working resource for researchers and practitioners in the areas of Refrigeration and Air Conditioning. It is also an ideal textbook for graduate and senior undergraduate students in mechanical, chemical, biochemical, industrial and food engineering disciplines.

Available in PDF, EPUB and Kindle. Book excerpt: The Exergy Method of Thermal Plant Analysis aims to discuss the history, related concepts, applications, and development of the Exergy Method - analysis technique that uses the Second Law of Thermodynamics as the basis of evaluation of thermodynamic loss. The book, after an introduction to thermodynamics and its related concepts, covers concepts related to exergy, such as physical and chemical exergy, exergy concepts for a control method and a closed-system analysis, the exergy analysis of simple processes, and the thermocentric applications of exergy. A seven-part appendix is also included. Appendices A-D covers miscellaneous information on exergy, and Appendix E features charts of thermodynamic properties. Appendix F is a glossary of terms, and Appendix G contains the list of references. The text is recommended for physicists who would like to know more about the Exergy Method, its underlying principles, and its applications not only in thermal plant analysis but also in certain areas.

Available in PDF, EPUB and Kindle. Book excerpt: The future market forces and environmental considerations in the passenger car and commercial vehicle sector mean more stringent engine downsizing is far more prevalent. Therefore, novel systems are required to provide boosting solutions including hybrid, electric-motor and exhaust waste energy recovery systems for high efficiency, response, reliability, durability and compactness. The current emission legislations and environmental trends for reducing CO2 and fuel consumption are the major market forces in the land and marine transport industries. The internal combustion engine is the key product and downsizing, efficiency and economy are the driving forces for development for both spark ignition (SI) and compression ignition (CI) engines in both markets. Future market forces and environmental considerations for transportation, specifically in the passenger car, commercial vehicle and the marine sectors mean more stringent engine downsizing. This international conference is the latest in the highly successful and prestigious series held regularly since 1978. These proceedings from the Institution's highly successful and prestigious series address current and novel aspects of turbocharging systems design, boosting solutions for engine downsizing and improvements in efficiency, and present the latest research and development in this growing and innovative area. - Focuses on boosting solutions including hybrid, electric-motor and exhaust waste energy recovery systems - Explores the current need for high efficiency, reliability, durability and compactness in recovery systems - Examines what new systems developments are underway
