主动式冷梁作为一种新的空调末端装置,对房间的温湿度与气流组织起重要作用,通过改变冷梁内部喷嘴间距,以诱导比、噪声标准、空气分布特性指标作为评价指标对冷梁内部喷嘴间距变化引起的冷梁流体输送性能的影响及经济性变化进行了评价分析,结果表明:喷嘴间距超过48 mm后,冷梁诱导比增幅明显收窄,且噪声超过标准限值;喷嘴间距从36 mm增加到48 mm,满足房间舒适性所需功率节约百分比为3.5%,喷嘴间距超过48 mm后,所需功率反而略有上升。
Active cold beam as a new air conditioning terminal device, the room temperature and humidity and air flow plays an important role in the organization by changing the internal nozzle spacing, to induce the ratio of noise, air distribution characteristics of indicators as an indicator of the cold beam The results show that when the nozzle spacing is more than 48 mm, the induced ratio of cold beam narrows obviously and the noise exceeds the standard limit. The nozzle spacing From 36 mm to 48 mm, the power savings required to meet room comfort were 3.5%, and with nozzle spacing greater than 48 mm, the power required increased slightly.
