不同人体座位模型对大空间空气分布影响

本文对座椅送风系统的气流组织进行模拟研究,首先运用座椅送风的简化模型,模拟了人体座椅实体的简化模型和虚区域热源模型下气流组织的情况,分析了两种情况的温度场,速度场和相对湿度场,发现人体座椅实体模型模拟的剧院气流组织速度、湿度与温度分布分层更加明显,此特点更易于微气候的分区控制,用更少的能量达到人体舒适的满意度。该研究为大空间建筑空调系统优化设计、模拟气流组织提供了方法及理论依据,同时对研究空气分布对空调系统的舒适性和节能方面的影响有一定的帮助作用。

The Effects of Different Models of Human Body Seat to Air Distribution in Large Space

The research on the simulating of air distribution of chair ventilation is explained in this paper.The authors first use the simplification model and the simulation method of chair ventilation to simulate the air distribution of manikin and chair ventilation model and virtual region heat source model,and then analyzed the temperature field,the velocity field and relative humidity field of the two situations.It is found that the velocity,humidity and temperature distribution stratify more obvious by manikin and chair ventilation model.The feature makes the control of microclimate in different divisions more easily,because it enables the satisfaction of human comfort with less energy.The study provides methods and theory of optimization design and air distribution simulation of air conditioning system in large space.Meanwhile,there is a definite inspiration to the study the effects of air distribution comfortableness and energy efficiency of the air-conditioning system.
