Abstract
针对太阳能有机朗肯-闪蒸循环(SBFC),本文基于EES(engineering equation solver)软件建立数学模型,以R245fa为循环工质,在集热器出口热水温度介于353.15~373.15K范围内,对平板集热器(FPC)和真空管集热器(ETC)驱动的SBFC系统热力性能以及投资成本进行了对比分析。选用的性能指标参数包括净输出功、热效率、第二定律效率、不可逆损失以及比初始投资。结果表明,随着集热器出口热水温度的增大,SBFC系统的热力性能显著升高,且采用ETC的系统比FPC系统在热力性能上更具优势,该优势随着热水温度的升高而持续增大。研究同时表明,在SBFC的投资成本中,太阳能集热器投资占比最大,且采用ETC的系统比初始投资远大于采用FPC的系统;此外,集热器出口热水温度的升高有利于降低SBFC系统的比初始投资
