摘要: This study presents an analysis of the performance organic Rankine cycle (ORC) subjected to influence working fluids. The effects various fluids on thermal efficiency and total heat-recovery have been investigated. It is found that presence hydrogen bond in certain molecules such as water, ammonia, ethanol may result wet fluid conditions due larger vaporizing enthalpy, regarded inappropriate for ORC systems. calculated results reveal a weak function critical temperature. maximum value occurs at appropriate evaporating temperature between inlet waste heat condensing In addition, increases with increase source decreases it by using having lower Analytical constant or based considerable deviation system design relative varying actual recovery inappropriate.
