On Suitability of Supercritical Carbon Dioxide As Heat Transfer Fluid in Flat Plate Solar CollectorBy Jahar Sarkar
Abstract: In the present article, carbon dioxide is proposed as a heat transfer fluid for flat-plate solar thermal collector. Energetic, exergetic and economic analyses of flat plate collector using supercritical CO2 have been done and compared with conventional fluid (water) as well as advanced fluid (nanofluids). Effects of zonal ambient temperature and incident solar radiation on collector efficiency, irreversibility, second law efficiency and collector size reduction are presented. Due to lower …

Cascade Refrigeration System with Internal Heat Exchanger: Suitable Natural Refrigerant Pair SelectionBy Jahar Sarkar
Abstract: In this study, thermodynamic analyses and optimization of various natural fluids as refrigerants in cascade system with internal heat exchanger have been done to get the suitable pair in a wide range of temperatures based on best system performance (maximum COP) as well as on operating characteristics. Out of the 56 possible combinations of high and low temperature fluids with 8 natural refrigerants (ammonia, carbon dioxide, propane, propylene, n-butane, isobutane, …
