Abstract

The use of Organic Rankine Cycle (ORC) in decentralized applications is linked with the fact that this process allows using low temperature heat sources and offers an advantageous efficiency in small-scale applications. The investigation of supercritical parameters in ORC applications seems to bring promising results in decentralized energy production. This paper presents the results from the simulation of the ORC process in normal and supercritical fluid parameters and discusses the efficiency variation in various applications. Performance calculation is presented for small scale power system based on ORC, in order to investigate the potential of this technology. A low-temperature solar Rankine system utilizing R245fa as the working fluid is proposed. The system consists of parabolic trough solar collector (PTSC) array, an ORC engine, and hot vapor condenser.
