Solar Refrigerating Systems

Abstract:

Along with the global warming impacts and climate changes, the demands for air conditioning and refrigeration have increased. Therefore, providing cooling by utilizing renewable energy such as solar energy is a key solution to the energy and environmental issues. In this paper are presented theoretical basis and practical applications for cooling technologies assisted by solar energy and their recent advances. The ejector cycle represents the thermo-mechanical cooling system, and has a higher coefficient of performance (COP) but require a higher heat source temperature than other cycles. Based on the thermal COP of each cycle, the absorption cycle which represents the thermal cooling is preferred to the ejector cycle. Next to improving efficiency of solar cooling technologies, research on advanced solar collector is the most important research topic.
