摘要
清华大学李先庭☆陆俊俊吴鹏赵彬摘要给出了座椅送风的简化模型和计算方法,将座椅送风工况下的风速和温度的模拟结果与实验小室的实测数据进行对比,二者吻合较好。利用简化模型模拟了相同设计条件下四种不同座椅送风形式的送风效果,结果表明,座椅下送风+椅背送风形式的热舒适性最好,座椅下送风形式热舒适性最差,另外两者居中。建议工程设计时应综合考虑热舒适性和经济性来确定座椅送风形式。
Presents the simplified model and calculating method. Compares the predicted distribution of air velocity and temperature with those obtained from experiments, and considers that the data agree well with each other. Simulates the effects of four kinds of chair ventilation by the simplified model under the same condition, as a result, under-chair with backrest ventilation has the best thermal comfort effect, underchair ventilation has the worst thermal comfort effect, and the thermal comfort of the others is between those of above two modes. Suggests that the thermal comfort effect and initial cost be taken into account in selection of ventilation type in project design.
