摘要/Abstract

摘要： 基于实验手段,首先在舒适性实验室得到了某贯流空调柜机在普通模式和低吹风感模式下的吹风感指数,实验结果表明低吹风感模式下的多孔射流有助于降低吹风感指数。随后通过仿真方法对该柜机空调的内部流场进行数值模拟分析,指出在低吹风感模式下,气流在导风板前进行了全局范围内的二次增压,使得压力能得以重新回收;回收的压力能随后通过导风板上的多孔射流进行了能量的重新分配释放,一方面提升了送风均匀性和送风范围,另一方面降低了最大出风速度,继而降低了房间的吹风感指数。最后通过仿真手段分析了低吹风感模式下出风口两侧凝露问题的产生机理,并依此对出口两侧进行结构优化,解决了低吹风感模式下出风口两侧的积水问题。

关键词: 柜机, 吹风感, 多孔射流, 凝露

Abstract: Based on experimental method, the draught rating of pioneer air conditioner with cross flow fan at normal mode and low-draught mode was gained in Comfort Simulation Room, and the experimental results showed multiple jets at low-draught mode helped to reduce draught rating. The paper then utilize numerical method to analyze the internal flow of pioneer air conditioner, indicating a secondary air pressure increase happened within the whole domain of air diffuser in the front of the air deflector, and the energy at the diffuser was recycled as a result. The energy was then re-released by multiple jets, leading to not only an increase in the uniformity and wideness of air supply, but also an decrease of maximum flow velocity, and the draught rating of the room decreased. In the end, the paper discussed the mechanism of condensation production at both sides of air outlet by numerical method, which was finally utilized to optimize the air outlet structure, giving a solution to condensation phenomenon within low-draught mode at both sides of air outlet.
