Abstract
Power systems based on Organic Rankine Cycle (ORC)
technology have been recognized as one of the most
promising solutions in converting low- and
medium-temperature heat into electricity. In this paper,
experimental results of the utilization of charge air
heat by means of ORC are presented. The experimental
setup consists of a 1.6 MWe diesel engine and an ORC
process utilizing charge air heat in which the
turbine-generator has been replaced with an expansion
valve. Thus, no mechanical or electrical power was
extracted from the system and the primary focus of the
experiments was to study the performance of the
evaporator acting as a charge air cooler. The studied
working fluids were R245fa and isopentane. The test runs
were carried out at full engine load and at engine part
loads. In addition, transient tests were carried out.
Based on the measured values the ORC utilizing charge air
heat was evaluated to be capable to increase the power
output of the test engine by 2%.
