摘要
为减少化石能源的使用,设计了一种以太阳能为辅助式能源的混合联供系统,并对其原理及运行策略进行分析.以上海市某商务楼为实例,建立能源、经济和环境等综合评价指标,基于遗传算法对系统的电制冷比和光伏板面积比进行优化分析;以分供系统为参照对象,分析太阳能系统对联供系统综合性能的影响.结果表明:混合联供系统的综合性能优于传统分供和联供系统;混合联供系统的最佳光伏板面积比受系统电制冷比的影响,当电制冷比设置合理时,系统综合性能达到最优.
To reduce the consumption rate of fossil fuels,a hybrid combined cooling,heating and power（CCHP）system with the utilization of solar energy was designed,of which the working principle and operation strategy were analyzed.Taking a commercial building in Shanghai as an example,the electric chiller ratio and PV arrays area ratio were optimized by genetic algorithm to achieve multi benefits of the hybrid CCHP system,including energy,economic and environmental benefits.Meanwhile,the effects of solar system on the comprehensive performance of hybrid CCHP system were analyzed with the separate production（SP）system as a reference object.Results indicate that the comprehensive performance of hybrid CCHP system is much higher than traditional SP and CCHP systems.The optimal PV arrays area ratio of hybrid CCHP system depends on its electric chiller ratio,and when the electric chiller ratio is reasonably set,optimum comprehensive performance can be obtained for the hybrid CCHP system.
