Performance of a thermally activated cooling system and design of a microchannel heat recovery unit

Creator:

Seward, Ryan

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...

Design and performance of a small scale waste heat recovery unit

Creator:

Ward, Christopher

Abstract:

A microchannel heat exchanger was designed for diesel waste heat recovery and its performance was evaluated. The 21x15x8 cm unit was constructed from diffusion brazed stainless steel lamina and weighed 11 kg. Operating from a 13.4 kW generator with an exhaust temperature of 500 °C the unit delivered 11.1 kW...

The geometric characterization and thermal performance of a microchannel heat exchanger for diesel engine waste heat recovery

Creator:

Yih, James S.

Abstract:

Rising energy demands and the continual push to find more energy efficient technologies have been the impetus for the investigation of waste heat recovery techniques. Diesel engine exhaust heat utilization has the potential to significantly reduce the consumption of fossil fuels and reduce the release of greenhouse gases, because diesel...
