Preliminary experimental results of an 11 kWe organic Rankine cycle

Abstract
The organic Rankine cycle (ORC) is considered a viable technology for converting low- and medium-temperature heat to electricity. However, many of ORC systems in practical applications operate in off-design conditions. In order to characterize this operation, experimental data is needed. In this paper, the commissioning of an 11 kWe ORC is described with special attention to the processing of the data. A filtering algorithm is introduced to isolate steadystate working points. This filter is then applied to the raw experimental data. In addition, the reliability of the experimental data is evaluated by investigating the heat balances over the heat exchangers and error propagation of the measurement uncertainties. The result of this work is a test-setup which is fully ready for high-accuracy and reliable measurements, including the post-processing steps. In the future, off-design models will be validated with the acquired experimental data and especially two-phase expansion will be further investigated.
