Abstract In the step towards the utilization of waste energy of Gas Turbine (GT) power plant exhaust gas, researchers have imposed adsorption refrigeration system over the absorption refrigeration due to several positive advantages. In the reported work, the system was analyzed based on first law efficiency. However, combining heat and work together for an evaluating system using first law efficiency would not provide a true picture of the performance of the system, whereas second law efficiency shows various irreversibilities associated with each component of the system and helpful in obtaining the optimum conversion of energy. In view of this, the presented paper studies performance analysis of GT power plant incorporated with the adsorption refrigeration system. Based on the parameters such as energy and exergetic efficiencies, cooling to power ratio and exergetic specific fuel consumption are considered for the system performance evaluation.

Vapor Absorption Refrigeration

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'.
