Download or read book Theoretical and Experimental Investigation of Silica Gel water Adsorption Refrigeration Systems written by Ahmed Rezk Masoud Rezk and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This PhD project was set out to improve the performance of silica gel / water adsorption cooling systems using a number of investigation tools. A novel global lumped analytical simulation model has been constructed for a commercialised two-bed silica gel / water 450kW adsorption chiller. It was integrated with a genetic algorithm (GA) optimisation toolbox to determine the optimum operating conditions to obtain the optimum chiller performance. The model was used to investigate the effect of physical and operating on the chiller performance. The model was also used to investigate the effect of various adsorbent bed enhancement techniques that are presented in published literature. An experimental test facility has been designed, constructed and commissioned to study the performance of scaled down adsorbent bed modules. It has been constructed to understand the effect of the operating conditions on adsorbent-bed heat and mass transfer performance. A dynamic vapour sorption (DVS) gravimetric analyser has been used to characterise a new species of adsorbents (MOFs). These adsorbents have strong potential towards water sorption and could replace the currently applied silica gel. MOFs adsorbents have been characterised in terms of adsorption isotherms and kinetics, in addition to its cyclic analysis. It was found that HKUST-1 (copper based MOF) outperforms silica gel with 95.7% increase in the water uptake. Iron based MOF (MIL-100) was found to outperform silica gel for high evaporating temperature application.

This book was released on 2021-04-01 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid chemisorption technology is an effective form of energy conversion for recovering low-grade thermal energy, but limited thermal conductivity and agglomeration phenomena greatly limit its performance. Over the past 20 years, researchers have explored the use of thermal conductive porous matrix to improve heat and mass transfer performance. Their efforts have yielded composite sorption technology, which is now extensively being used in refrigeration, heat pumps, energy storage, and de-NOx applications. This book reviews the latest technological advances regarding composite solid sorbents. Various development methods are introduced and compared, kinetic models are presented, and different cycles are analyzed. Given its scope, the book will benefit experts involved in developing novel materials and cycles for energy conversion, as well as engineers working to develop effective commercialized energy conversion systems based on solid sorption technology

Available in PDF, EPUB and Kindle. Book excerpt: Air conditioning system is one of the major consumers of electrical energy in many parts of the world today. It represents between 40 and 70% of the energy consumption in commercial buildings. The demand of energy for air conditioning systems is expected to increase further in the next decades due to the population growth, the new economic boom, and the urbanization development. The rapid growth of air conditioning and electricity consumption will contribute further to climate change if fossil and nonrenewable resources are used. More energy-efficient and renewable energy-based air conditioning systems to accomplish space cooling are needed. This book intends to provide the reader with a comprehensive overview of the current state of the art in sustainable air conditioning technologies and focus on the most recent research and development on green air conditioning systems including energy-efficient and renewable energy-based air conditioning systems.

Download or read book Dynamics of Adsorptive Systems for Heat Transformation written by Alessio Sapienza and published by Springer. This book was released on 2018-03-07 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates the adsorption dynamics of water, methanol, ethanol, and ammonia vapor on loose and consolidated adsorbent beds, as well as the impact of this aspect on the overall performance of adsorption systems for heat transformation. In particular, it presents the results of kinetic measurements made using the large temperature jump (LTJ) method, the most efficient way to study adsorption dynamics under realistic operating conditions for adsorptive heat transformers. The information provided is especially beneficial for all those working on the development of novel adsorbent materials and advanced adsorbers for heating and cooling applications. Today, technologies and systems based on adsorption heat transformation (AHT) processes offer a fascinating option for meeting the growing worldwide demand for air conditioning and space heating. Nevertheless, considerable efforts must still be made in order to enhance performance so as to effectively compete with commonly used electrical compression and absorption machines. For this purpose, intelligent design for adsorption units should above all focus on finding a convenient choice of adsorbent material by means of a comprehensive analysis that takes into account both thermodynamic and dynamic aspects. While the thermodynamic properties of the AHT cycle have been studied extensively, the dynamic optimization of AHT adsorbers is still an open issue. Several efforts have recently been made in order to analyze AHT dynamics, which greatly influence overall AHT performance.
