摘要
探讨利用太阳能在降低建筑能耗的同时又满足居住者舒适度需求,有利于改进建筑结构设计,利用可再生能源资源(风能、太阳能等),优化能量管理方式,降低建筑自身能耗以达到低排放或零排放目的。利用太阳能的能量补偿作用以及建筑自身的储热效应,根据国际ASHRAE标准设计满足舒适度指标要求的节能控制系统,以实现节能和舒适性双目标。首先分析了建筑围护结构散热、空气渗透失热、建筑内部热扰、太阳辐射获得热能以及设备的耗能等影响室温的多种耦合因素,然后利用仿真软件ENERGYPLUS和建筑控制虚拟试验平台(BCVTB)搭建了具有三个区域的办公建筑模型,综合利用制热-通风-空调系统(HVAC)设备及日照能量补偿的多种组合,进行了仿真试验。讨论了同时满足舒适性和节能双目标的最优控制方案。实验结果表明:利用可再生能源,在维持舒适性的同时,可以减少建筑能源消耗。研究量化了光照的能量补偿效果,并设计了相应的控制策略,为实现低/零能耗建筑提供参考方案。
Using solar energy to reduce the energy consumption of buildings while meeting the comfort needs of residents is conducive to improving the structural design of buildings,using renewable energy resources such as wind and solar energy,optimizing energy management modes and reducing the energy consumption of buildings to achieve low or zero carbon emissions.Using the energy compensation effect of solar energy and the heat storage effect of the building itself,an energy-saving control system that meets the requirements of comfort indexes is designed according to the international ASHRAE standards to achieve the dual goals of energy saving and comfort.Firstly,various coupling factors affecting the room temperature such as heat dissipation from building envelope,heat loss from air infiltration,thermal disturbance inside the building,heat energy from solar radiation and energy consumption of equipment are analyzed,and then an office building model with three zones is built by using simulation software ENERGYPLUS and Building Controls Virtual Test Bed(BCVTB).Simulation tests are conducted by comprehensively using the various combinations of heating,ventilation and air-conditioning(HVAC)system equipment and daylight energy compensation.The optimal control scheme that meets both the comfort and energy saving goals is discussed.The experimental results show that the use of renewable energy can reduce the energy consumption of building while maintaining comfort.The study quantifies the energy compensation effect of daylight and designs corresponding control strategies to pro-vide reference for achieving low/zero energy buildings.
