Abstract | The performance of a combined vapor-compression cycle/ORC is evaluated using waste-heat from a diesel generator. A flat plate microchannel heat exchanger is employed to provide energy exchange between the diesel exhaust stream and an oil loop, which provides energy to a boiler. This study finds an increased diesel duty corresponds with an increased cooling capacity, for a maximum of 5 kW of cooling (with 13.5 kWe diesel load). System COP is reduced with a higher input power due to limitations in the cooling cycle. A number of solutions are identified to increase the COP and cooling capacity. A new microchannel heat exchanger to recovery heat is designed to increase performance compared to the previous version. |
