摘要:
为研究环保新型有机工质应用于微型朗肯循环热电联供系统的适应性和循环效率,针对3种有机工质HFE7000,HFE7100和Neo-pentane,构建了典型微型有机工质朗肯循环热电联供循环系统,并建立了系统热力学能量流通模型,研究了循环温度、回热器温差、过热和过冷对系统效率的影响.结果表明:所选工质可适用于微型有机朗肯循环,有机工质自身性质对循环效率有一定影响;系统各项效率均随着蒸发器出口温度的升高和冷凝器出口温度的降低而增加;在循环中增设回热器有利于提高系统发电效率,有机工质在回热器进出口之间每10 ℃的温度差,可将微型有机朗肯循环系统的发电效率提高0.4%~0.5%;对工质采用过热和过冷手段,均会降低微型有机朗肯循环系统的循环效率.
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.
