This report describes the modifications and repairs made to the 200 ton absorption refrigeration pilot plant since April 1992, when Clarkson University assumed responsibility for it. Current operating problems and the performance of the plant, achieved to date, are detailed. Performance has been limited by small air leaks into the absorption section of the plant and by plugging in a heat exchanger which has limited the flow of purified glycol to the absorber. Nonetheless, the plant has been operated for periods of over eight hours with sustained cooling loads of 40 tons. Chilled water has been produced at a temperature as low as 38 degrees Fahrenheit. The principal leak sources have been pinpointed. Plans are described for achieving plant operation at designed levels.

This book provides a detailed analysis of absorption refrigeration systems, covering single effect to multi-effect systems and their applications. Both the first and second laws of thermodynamics are discussed in relation to refrigeration systems to show how system performance differs from one law to another. Comparative energy and exergy analyses and assessments of single effect, double effect, triple effect and quadruple effect absorption refrigeration system are performed to illustrate the impact of an increase in the number of effects on system performance. In particular, the second law (exergy) formulation for absorption refrigeration systems, rarely discussed by other works, is covered in detail. Integrated Absorption Refrigeration Systems will help researchers, students and instructors in the formulation of energy and exergy efficiency equations for absorption refrigeration systems.

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.

O presente trabalho analisa experimentalmente um ciclo de refrigeração por absorção operando em regime transiente. 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.
