Energy And Exergy Analysis

The solar photovoltaic system generates both thermal energy and electrical energy by utilizing solar energy. In this paper an experimental attempt has made for calculating energy output as well as exergy output of solar PV panel installed at R.L.J.I.T. Bangalore. Energy and exergy analysis was performed by using first and second law of thermodynamics to evaluate energy and exergy. The framework involved in this process are ambient temperature, overall heat transfer, open-circuit voltage, short-circuit current, fill factor, solar radiations etc. It is predicted that temperature of pv solar module has most effect on the efficiencies. By the help of water or air the heat can be removed to improve both energy and exergy efficiencies.

An NH 3– H 2 O ejector-absorption refrigeration cycle, and an R-152a ejector refrigeration cycle are employed with a renewable energy power generator to make a proposed compact power generation and triple effect ejector-absorption refrigeration cycle. The exergy analysis of the cycle leads to a possible performance improvement. Approximately 71.69% of the input exergy is destructed due to irreversibilities in different components. Around 7.976% is available as the useful exergy output. The exhaust exergy lost to the environment is 20.33%, which is lower than the exhaust energy loss of 47.95%, while the useful energy output is 27.88%. The refrigerants used are of zero ODP and negligible GWP, and the CO 2 emission of the exhaust gases is very small as compared to that of the fossil fuel run engine, hence, this cycle is favorable to the global environment. The results also show that the proposed cycle has significant higher energy and exergy efficiency than the earlier investigated 'triple effect refrigeration cycle' and 'the combined power and ejector-refrigeration cycle'.
