Performance analysis of cogeneration systems based on micro gas turbine (MGT), organic Rankine cycleand ejector refrigeration cycle

Zemin BO, Kai ZHANG, Peijie SUN, Xiaojing LV, Yiwu WENG

Frontiers in Energy 2019, Volume 13, Issue 1,   Pages 54-63 doi: 10.1007/s11708-018-0606-7

Abstract: In this paper, the operation performance of three novel kinds of cogeneration systems under design andThe systems are MGT (micro gas turbine) + ORC (organic Rankine cycle) for electricity demand, MGT+ ERC(ejector refrigeration cycle) for electricity and cooling demand, and MGT+ ORC+ ERC for electricityThe effect of 5 different working fluids on cogeneration systems was studied.because the bottoming cycle can compensate for the power decrease of MGT.
