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: It is almost impossible to imagine life today without the electronics, communications and networks we have all come to take for granted. The 6G network is currently under development and some chips able to operate at the Terahertz (THz) scale have already been introduced, so the next decade will probably see the consolidation of 6G-based technology, as well as many compliant devices. This book presents the proceedings of the 11th International Conference on Electronics, Communications and Networks (CECNet 2021), initially planned to be held from 18-21 November 2021 in Beijing, China, but ultimately held as an online event due to ongoing COVID-19 restrictions. The CECNet series is now an established annual event attracting participants in the interrelated fields of electronics, computers, communications and wireless communications engineering and technology from around the world. Careful review by program committee members, who took into consideration the breadth and depth of those research topics that fall within the scope of CECNet, resulted in the selection of the 88 papers presented here from the 325 submissions received. This represents an acceptance rate of around 27%. Providing an overview of current research and developments in these rapidly evolving fields, the book will be of interest to all those working with digital communications networks.

Download or read book Advances in Carbon Dioxide Compression and Pipeline Transportation Processes written by Andrzej Witkowski and published by Springer. This book was released on 2015-05-25 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing a comprehensive analysis of CO2 compression, transportation processes and safety issues for post combustion CO2 capture applications for a 900 MW pulverized hard coal-fired power plant, this book assesses techniques for boosting the pressure of CO2 to pipeline pressure values with a minimal amount of energy. Four different types of compressors are examined in detail: a conventional multistage centrifugal compressor, integrally geared centrifugal compressor, supersonic shock wave compressor, and pump machines. The study demonstrates that the total compression power is closely related to the thermodynamic process and is not determined by compressor efficiency alone. Another problem addressed is that of CO2 pipeline transport from the compressor outlet site to a disposal site under heat transfer conditions. The book also features an analysis of simulations and models that are used to determine the maximum safe pipeline distance to subsequent booster stations as a function of inlet pressure, ambient temperature, thickness of the thermal insulation and ground-level heat flux conditions. This book focuses on compression as well as transportation processes with particular emphasis on the safety risks related to the transport of CO2. The most important problem in terms of environmental protection is ensuring precise and reliable hazard identification. As hazards can only be managed effectively if they are properly identified, problems involving the discharge and atmospheric dispersion of CO2 are also discussed.
