Development of a continuously operating solar powered refrigeration system.

摘要

The air-conditioning and refrigeration systems in the KSA consume more than 60 % of the electrical energy consumption of the building sector. Most of the used systems are of the vapor-compression type. Using solar energy to power such systems will save a large amount of electrical energy that can be utilized by the production sectors such as the industry. Hence, the focus of the proposed thesis topic is to develop a continuously operating fully solar-powered absorption refrigeration system that can provide a 24-hour service of refrigeration and/or air-conditioning. The development will include an in-depth review of the design and operation of the conventional and solar-assisted absorption refrigeration systems, analysis of refrigerant-absorbent solutions for solar-powered systems, coming-up with new alternative designs, detailed thermodynamic analysis of some of the new alternative designs, selection of the most suitable alternative design and finally preparation of the working drawings for a model of the selected design.
