摘要
结合工程实际,选取某公建地板送风空调系统外区典型房间作为研究对象,通过理论计算与CFD软件模拟相结合的方法,对该典型房间在变工况运行下的三种调节方式进行了对比分析.结果表明:变风量调节模式下室内热舒适性最佳;变送风温度调节模式下室内空气品质最佳;同时改变送风量和送风温度的调节模式下,可满足变工况运行下的室内热舒适性、室内空气品质均与设计工况下的情况基本相同的要求.
This paper, combing with engineering practice, takes the typical conditioned space of underfloor air distribution （UFAD） system in perimeter zone as the research object. Three kinds of regulating modes under variable working conditions were analyzed and compared regarding their merits and demerits by using theoretical calculation combined with CFD simu-lation. Result indicates that the indoor thermal comfort is the best under the variable air volume adjustment mode. The indoor air quality is the best under the variable air temperature adjustment mode. The indoor thermal comfort and indoor air quality in variable working condition could be same to those in the design condition under the adjustment mode of changing both air volume and air temperature.
