摘要
The Trilateral Flash Cycle (TFC) and the Partially Evaporating Cycle (PEC) have been analyzed and compared to the Organic Rankine Cycle (ORC). Three cases have been investigated. Case I uses air at 100 degrees C, Case II air at 150 degrees C and Case III air at 200 degrees C as the heat source. Water at 20 degrees C is used as the heat sink for all cases. The cycles are optimized for maximum net power production with eight different working fluids, R123, R134a, R245fa, R1234ze, butane, pentane, isopentane and propane. Detailed heat exchanger models to calculate the pressure drops and heat transfer coefficients are included in the model. The results show that the TFC has the lowest power production for all cases, and the total system size is estimated to be larger for the TFC compared to the other cycles. The PEC doesn't show any advantage over the ORC for the cases analyzed here.
