摘要
本文构建了一套基于质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell,PEMFC)、吸附式制冷机和除湿轮的冷热电湿联供系统,通过吸附式制冷机和除湿轮对PEMFC产生的余热进行充分利用,在满足供电需求的同时,实现房间热环境夏季制冷与除湿处理.为改进联供系统在动态波动负荷需求下的供能匹配性设计,提出一种柔性调控方法,以人体热舒适度为基础,对房间设定温度进行柔性调节,并通过模拟方法对比分析了调控前后系统的运行特性与节能潜力.
Abstract
In this paper,a combined cooling,heating,power and humidity system driven by proton exchange membrane fuel cell(PEMFC)is designed and simulated.An adsorption chiller and a desiccant wheel is selected in the system to fully utilize the waste heat generated by PEMFC.The proposed system can realize cooling and dehumidification in summer while meeting the power demand.To improve the matching design of the cogeneration system with dynamic fluctuating building loads,a flexible load regulation strategy is proposed to control the room setting temperature based on the human thermal comfort.The operational characteristics and energy saving potential of the proposed system with flexible regulation are systematically investigated.
