摘要:
为了得到地板送风系统理想的送风参数,首先通过正交实验研究不同送风参数对地板送风系统房间温度分布、热舒适性和空气品质的影响,然后采用控制变量法进一步研究送风温度和速度对系统性能的影响,最终通过EnergyPlus能耗模拟软件计算得到供冷工况下热分层良好、舒适性较好且能耗较低的理想送风参数.实验结果表明:当旋流风口到人体的距离为0.7 m,送风温度为18~20 ℃,送风速度在1.2~1.5 m/s时,室内热分层较好,能够满足人员热舒适性和空气品质的需求.对不同送风参数下运行特性与能耗影响的模拟计算表明:在理想送风参数范围内,当送风温度为18 ℃、送风速度为1.2 m/s时,地板送风系统不仅可以保持较好的热舒适性和良好的热分层,同时还具有较低的能耗.
Abstract:
In order to obtain the desired air supply parameters in UFAD(underfloor air distribution)system, the orthogonal experiments were employed to investigate the effects of air supply parameters on the distribution of temperature, thermal comfort and indoor air quality.Then, the impacts of the air supply temperature and velocity on the UFAD system performance were studied by using the method of controlling variables. Finally, the preferable air supply parameters which contribute to better thermal stratification, better comfort and lower energy consumption under cooling operating conditions were obtained by EnergyPlus energy consumption simulation software. The results show that better thermal stratification, thermal comfort and good indoor air quality are achieved with the distance between swirl diffusers and human of 0.7 m, the air supply temperature of 18 to 20 ℃ and the air supply velocity of 1.2 to 1.5 m/s. The simulation results of operation characteristics and energy consumption with different air parameters show that as the air supply parameters are reasonable, the satisfied thermal comfort, thermal stratification and prominent energy saving can be achieved simultaneously with the air supply temperature of 18 ℃ and velocity of 1.2 m/s.
