Abstract:
In this present work, thermo-economic assessment of a cascade ORC-ejector
chiller is proposed in an attempt to demonstrate the ORC system efficiency
improvements and the equipment cost which must be used for operation. The energy
analysis are implemented to demonstrate thermodynamic performance when the
cascade system is compared with the conventional ORC system. The economic
assessment which aims to determine all equipment cost and to demonstrate the payback
period under various operating conditions. The analysis is implemented under a heat
source temperature of 90°C which is used to operate with both ORC and ejector cooling
system. The chilled water produced by the ejector-chiller is ranged from 16 - 22°C. The
working fluid for the cascade and the conventional systems is R245fa which has
reasonable global warming potential (GWP) and low ozone depletion potential (ODP).
The energy efficiency improvement is proposed and discussed under various operating
conditions. This research shows the technological guidelines to the ORC performance
improvement operating at quite high ambient temperature. The reasonable payback
period is achieved around 3.8 4.3 years for these demonstrations. This payback period
varies with the working conditions of the inter-cooler temperature. The research also
shows that reducing the condensation pressure produces a significant increase in the
useful mechanical work and thermal efficiency. Hopefully, the results proposed in this
work is useful for the researcher who attempts to develop ORC technology under hot
and humid climate
