energy, exergy and economic analysis of a multi-generation system using the waste heat of a wind turbine

Due to the increasing consumption of fossil fuels and the resulting environmental pollution, using renewable and clean energy has been considered and various research has been conducted for investigating the possibility of using them as a stimulus for different energy conversion systems. compared to other renewable energy sources, wind energy has the least harm to the environment. the waste heat energy in the wind turbine gearboxes in the temperature between 〖100〗^o c to 〖150〗^o c can be used as a stimulus for low-temperature systems. in the present study, using this low-temperature energy has been studied as an energy source for a power-cooling absorption cycle and a domestic hot water heat exchanger. at first, the energy, exergy, and exergy-economic formulation of the system is presented. then, in the results section after the validation study, a comprehensive parametric analysis has been conducted to investigate the influence of changing the effective parameters such as the average wind speed, and the temperature on the performance of the proposed system. the obtained results show that the effect of changing the wind speed on the performance of the system is greater than other parameters.
