Abstract:
Organic Ranking Cycle (ORC) is one of the most promising methods for converting low-grade heat into power. In this paper, an experimental ORC system, which includes a single screw expander, a shell and tube evaporator, an air-cooled fin-and-tube condenser and a metering pump, has been built. R245fa was adopted as the working fluid considering of its good performance and environmentally-friendly characteristics. The heat source of the experimental system is the conduction oil which was heated by electricity. In the evaporator of the system, R245fa was evaporated into vapor by the high-temperature conduction oil. Experiments were conducted to analyze the operational characteristics and performance of the developed ORC. The key parameters of the ORC, such as the efficiency of the cycle and the expander, were obtained. In addition, the factors which inﬂuence the performances of the developed ORC were analyzed and discussed.
