A Solar Powered Air Conditioning System for Daytime Offices based on Ejector Cycle: An Alternate of Conventional Air Conditioning Systems
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 8
Abstract
Solar cooling is comprised of many attractive features and is one path towards a more sustainable energy system. The performance of solar cooling systems is strongly dependent on local conditions. Solar cooling systems can be efficiently operated in locations where sufficient solar radiation and good heat sink are available. A low temperature heat source could be used to drive the ejector refrigeration system, making this system suitable for integration with the solar thermal energy. The analysis of the solar driven ejector system is followed by steady state analysis condition. The system performance depends on the working fluid (refrigerant) chosen, operating conditions and ejector geometry. An ejector refrigeration cycle, when, using natural working fluids generates good performance and lower environmental impact, rather than traditional working fluids, as CFC’s and HFC’s are strong climate gases. Exergy analysis illustrates that the distribution of the irrervsibilities in the cycle between components depends strongly on the working parameters. The most significant losses in the system are in the solar collector and ejector. The final section of the paper will deal with the calculation results for one fixed ejector dimension using R11 as the refrigerant are also included.
