摘要
净零能耗(NZE)建筑的能源来源于清洁的可再生资源.本文以一个包含一个足球场和两个游泳池的体育中心为研究对象,基于净零能耗(NZE)概念对体育中心进行设计和分析.虽然这类体育中心很常见,但针对这类体育中心开发净零能耗系统的研究却非常有限.在体育中心的屋顶上安装了10000 m2的太阳能光伏板,提供其所需的能量.白天产生的能量通过压缩空气储能(CAES)循环储存起来,在日落后按需使用.压缩空气驱动涡轮机,为体育中心提供所需的电力;同时,产生的热能被用来加热游泳池;利用环境和气象数据进行瞬态研究.利用TRNSYS软件进行了动态模拟;结果表明,该循环的总效率约为44%,如果使用游泳池的热能,则可提高到98%.由于太阳能的波动,平均所需能源的14%应由电网提供,且每天可出售超过26 MW·h的能源到电网.这项研究的结果有助于设计NZE运动场馆,实现能源的可持续管理.
Abstract
Net zero energy(NZE)buildings obtain their energy from clean renewable resources.The current study aims to design and analyze a pioneering sports complex based on the net zero energy(NZE)concept,incorporating a football stadium and two swimming pools as a case study.Despite the common occurrence of such sports complexes,limited studies have been conducted to develop NZE systems tailored to this type of sports complexes.A solar field with 10000 m2 photovoltaic panels installed on the rooftop of the stadium provides the required energy.The generated energy in daytime is stored through compressed air energy storage(CAES)cycle to be used after sunset on demand time.The compressed air runs turbines and generates the required electricity for the stadium.Also,the generated thermal energy is used to warm up the swimming pools.Environmental and meteorological data are used to perform transient studies.Dynamic simulations are done through TRNSYS,and results show that the overall efficiency of the cycle is around 44%which can increase to 98%if using the thermal energy in swimming pools.Due to solar energy fluctuations,on average,14%of the required energy should be provided from the grid,while more than 26 MW∙h a day can be sold to the grid.Results of this study help to design NZE sport complexes to move toward sustainable energy development.
