摘要
针对侧墙上置风口置换通风方式,测试了房间非等温送风射流发展的速度场和室内空间的温度场,利用送风射流无因次速度变化曲线,分析了组合射流发展规律及其对通风效率的影响,基于送风速度与热源强度双因素,阐明了耦合作用对通风效率的影响,并指出了风口结构对通风效率影响。
About the ventilation pattern of displacement ventilation system with high sidewall outlet, tests the velocity distribution of the non-isothermal air jet and the temperature field in room, using the ventilation jet non-dimensional velocity change curve, analyses the combination jet flow regulation and its influence on the ventilation efficiency, explains the influence of coupling action on the ventilation effect based on the two factors of supply air velocity and heat source intensity, and presents the influence of diffuser physical configuration on the ventilation effect.
