This study proposes and investigates a novel VCES (Vehicle power and cooling/heating Cogeneration Energy System), including a topping vehicle engine subsystem, and a bottoming waste-heat recovery subsystem which uses the zeotropic working fluid. The various grade exhaust and coolant waste-heat...

Because of the global increase in the consumption of low-calorie natural gas, and increasing awareness of the mid-to long-term problem with the decrease in the calorific value of natural gas, actions are needed to minimize the problems with gas appliances. Most natural gas engines for small...

This paper proposes optimum green energy systems for electricity generation of island resorts in Malaysia. A combination of solar energy and wind energy as intermittent renewable energy sources with a fuel cell (FC) system and a battery storage energy system as a backup to the green energy...

Waste heat recovery has been commonly accepted as an efficient, clean, reliable, and promising approach to increase the utilization efficiency of primary energy and reduce the pollutant emissions. A RNGCS (retrofitted natural gas-based cogeneration system), in which domestic hot water is heated...

By integrating neural networks (NNs) with turn-on transient energy analysis, this work attempts to recognize demand load, including the buyers’ load on the power systems and the internal load on the cogeneration systems, thereby increasing the recognition accuracy in a non-intrusive energy...

The suitable size (electricity output capacity) of micro gas turbine cogeneration systems (MGT-CGSs) depending on scale of the sewage treatment plant was investigated. Since heat demand of the plant is affected by ambient temperature, performance under three typical ambient temperature...
