微型有机朗肯循环热电系统建模与性能分析
Modeling and performance analysis of micro-CHP system with organic rankine cycle
摘要
Abstract
To investigate the suitability and cycle efficiency of novel environment friendly organic working fluid applied to the micro combine heating and power (M-CHP) system,organic Rankine cycle (ORC) in the M-CHP system was constructed and thermodynamically analyzed for three organic fluids HFE7000,HFE7100 and Neo-pentane.The effects of the cycle temperature,the temperature difference of the internal heat exchanger (IHE),and superheating and subcooling on the cycle efficiency were studied.The results show that the proposed organic fluids are adaptive in the M-CHP system and have effect on the cycle efficiency.Both the increase of the evaporator temperature and the decrease of the condenser temperature increase the CHP electrical efficiency.The use of the IHE can increase the electrical efficiency of the M-CHP system,which approximately increases by 0.4％ to 0.5％ for every 10 ℃ temperature drop on the IHE warm side.Both superheating and subcooling decrease the CHP electrical efficiency.关键词
