This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Carbon dioxide is a natural refrigerant that has been considered for certain refrigeration and air conditioning applications. The coefficient of performance (COP) of carbon dioxide cycles is low compared to classical vapor compression cycles. The aim of this portion of the thesis is to present a thermodynamic analysis of carbon dioxide cycles in order to evaluate the potential performance of a refrigeration cycle using carbon dioxide. A thermodynamic model for the cycle is proposed which can simulate the operation of a carbon dioxide refrigeration cycle. This model takes into account the practical effects of the thermo-physical properties of carbon dioxide as a refrigerant in a trans-critical cycle. One and two-stage compression processes were considered for comparison purposes. A sensitivity analysis has been conducted so that cycle performance can be estimated. The effect of cycle components on system capacity and cycle performance was investigated. The second portion of the thesis deals with the concept of reheat air conditioning, and looks at the performance of different reheat cycles. The thesis looks at reheat systems that utilize different placements of the reheat coil. The overall performance ofthese reheat systems is then calculated. These systems require no additional electric power to reheat the air after it is cooled and dehumidified in the evaporator. Instead, theyuse heat from the condenser heat exchanger to reheat the air during partial load conditions. Four different reheat configurations are discussed and analyzed to determine performance levels. Visual Basic programs were written for each of the four cycles to simulate the different configurations and to evaluate key performance parameters. Graphs were developed based on these programs, where critical variables were changed to monitor trends in coefficient of performance. The thermodynamic cycle of each reheat configuration is developed, with equations presented with figures depicting the cycles. Refrigerant 134a was used in the programs throughout the reheat section of the thesis. The reheat coefficient of performance is used as the basis for cycle comparison. The relative performance of the four cycles is illustrated in the figures and explained in the Results and Discussion section at the end of chapter 3.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a wide-ranging review of the latest research and development directions in thermal systems optimization using population-based metaheuristic methods. It helps readers to identify the best methods for their own systems, providing details of mathematical models and algorithms suitable for implementation. To reduce mathematical complexity, the authors focus on optimization of individual components rather than taking on systems as a whole. They employ numerous case studies: heat exchangers; cooling towers; power generators; refrigeration systems; and others. The importance of these subsystems to real-world situations from internal combustion to air-conditioning is made clear. The thermal systems under discussion are analysed using various metaheuristic techniques, with comparative results for different systems. The inclusion of detailed MATLAB® codes in the text will assist readers—researchers, practitioners or students—to assess these techniques for different real-world systems. Thermal System Optimization is a useful tool for thermal design researchers and engineers in academia and industry, wishing to perform thermal system identification with properly optimized parameters. It will be of interest for researchers, practitioners and graduate students with backgrounds in mechanical, chemical and power engineering.
