conditioning), refrigeration, and automotive industries for use in an ORC (organic Rankine cycle). A theoretical analysis and an … experimental study are carried out for an ORC with R134a as the working fluid, utilizing a low-temperature heat source (Tsource … < 150 °C), with focus on the expansion and boiling processes. The complete ORC model is comprised of models for the expander …

In this study, a μ-ORC (micro organic Rankine cycle) generator that produces net positive power from low-grade heat (i ….e., temperature below 100 °C) was experimentally demonstrated. First, the basic performance of a 10-Wp μ-ORC prototype with a small … prototype μ-ORC was coupled with a DC generator to produce a net electrical power of 5 W without an external electricity supply …
