There is a demand for reduced power consumption in the vapor compression refrigeration cycle. Coefficient of performance of window-air conditioners considerably decreases and power consumption increases under very hot conditions. These problems have encouragecl studies aimed at improving the performance of window-air-conditioners by enhancing the heat transfer rate in the condenser. In this ar...

In the era of coal power station phase-out, natural gas fired combined cycle will drive energy transition towards sustainable generation. a panorama strong requirement for grid flexibility and non-dispatchable renewable penetration, survival thermal plant is strictly linked with operating successfully in compensating fluctuating production through flexible The Italian case taken as reference, c...

Turbocharged CNG engines produce high NOx emission due to the fuel type and high combustion temperature. In this research, the effects of lean-burn and waste gate opening pressure threshold on NOx emission are studied theoretically and experimentally at WOT condition as well as 13-mode ECE-R49 test cycle. A code is developed in MATLAB environment for predicting engine NOx and the results are va...

Modular and scalable distributed generation solutions as combined cooling, heating power (CCHP) systems are currently a promising solution for the simultaneous of electricity useful cooling large buildings or industries. In present work, solar-heated trigeneration approach based on different organic Rankine cycle (ORC) layouts single-effect H2O/LiBr absorption heat pump integrated bottoming is ...

Waste heat recovery (WHR) can represent a solution to improve the efficiency of ships’ propulsion, helping exceed stringent greenhouse gas emission limits. This is particularly suitable in case propulsion based on turbines due their medium-high temperature level exhaust gases. study analyzes performance hybrid energy grid, which recovered by gases an aeroderivative turbine, GE LM2500+, when bot...
