摘要：以柴油发动机缸套水和尾气废热为热源，设计开发了有机郎肯循环ORC的热力循环系统及发电装置。在该系统中，采用R245fa 作为循环工质，以板式蒸发器和冷凝器作为工质相变的换热元件，机械能与电能转化。ORC系统测试结果表明，在ORC系统和发动机长时间稳定运行，稳定发电量14.4kw，发电效率7.2%；净发电量12.45kw，净发电效率6.25%。在保持发动机稳定运行和冷却水全部进行大循环的前提下，发动机出水温度降低，有利于总发电量和净发电量的提升。

Abstract: Based on the waste heat characteristic from the coolant and exhaust gas of diesel engine, the Organic Rankine Cycle (ORC) commercial product systems had been development. The working fluid is the R245fa, the plate type condenser and evaporator are used. The ORC systems absorb the heat form coolant and exhaust gas, and bring the 14.5 kw electric energy. The efficiency based on the first law of thermodynamics is 7.2%; completely generating efficiency is 6.25%.

Key words: Organic Rankine cycle , waste heat, diesel engine, generate electricity
