Abstract
The world faces a global and potentially devastating global energy crisis. People have already realized that traditional resources such as oil and gas cannot meet the growing demand for energy. This has led to increased interest in alternative energy research such as solar, geothermal and wind energy. In addition, the use of traditional energy resources causes serious environmental problems. In addition to the result of population growth and rapid development in the industry, the amount of freshwater available on the surface of the globe is not enough to meet the daily needs as it has become a problem facing the world, especially the Middle East. In addition, due to the continuous rise in global temperatures, air conditioning is becoming necessary. In order to overcome the problem of lack of freshwater, this is done by desalination of salt water to produce freshwater. In addition to overcoming the problem of high temperatures, this has been achieved through the use of desiccant air conditioning systems, which is characterized by the elimination of the problem of chlorofluorocarbons (CFCs) or hydro chlorofluorocarbons (HCFC) produced by the Freon used in conventional air conditioning systems to depletion of the ozone layer and the potential for global warming. In response to these problems, the human thermal comfort issues, distillate water productivity, and the energy saving represent the main objective of the present study. To investigate this idea, the desiccant air conditioning system assisted by a solar energy coupled with the external condenser to produce the distillate water, as well as, the desiccant air conditioning system assisted by a solar energy coupled with HDH desalination system was studied numerically and experimentally under the Egyptian conditions. Organization of the thesis The thesis compromises eight chapters where the summary of each chapter is given below: Chapter 1 This chapter shows the objectives of using the solar energy assisted desiccant air conditioning system coupled with the external condenser to produce the distillate water, as well as, the solar energy assisted desiccant air conditioning system coupled with HDH desalination system. Chapter 2 This chapter includes a review of previous studies of the desiccant air conditioning system and humidification-dehumidification desalination system. Also, the objective of the present study was presented. Chapter 3 In this chapter, the mathematical model has been developed to predict the operating performance of the solar energy assisted desiccant air conditioning system coupled with the external condenser to produce the distillate water, as well as, the solar energy assisted desiccant air conditioning system coupled with HDH desalination system. Chapter 4 This chapter is divided into two main parts. The first part describes the experimental test-rig which contains the experimental apparatus. While the second part is devoted to provide a brief description of the employed measuring techniques. Chapter 5 This chapter includes the numerical results of the proposed system. Chapter 6 This chapter includes the experimental results of the proposed system. Chapter 7 This chapter presents the drawn conclusions and suggestions of future work.
