Abstract
In this paper, a new cogeneration system is proposed by combining ejector heat pump with organic Rankine cycle, which can output power and domestic hot water simultaneously. The ejector heat pump is used to increase the mass flow rate of the working fluid flowing through the expander, thereby increasing the net power output. The performance of the new cogeneration system is studied by parametric analysis, exergy analysis, and economic analysis. The results show that the net power output is better (6.11%) when the high-temperature evaporation pressure is low and the expander intake pressure is high. There is an optimal condensation pressure that optimizes the investment recovery period. When the new cogeneration system’s net power efficiency and exergy efficiency is better, the economics of the system is difficult to improve.
