摘要
为研究空调房间内的热舒适度,应用k-ε湍流模型和数值模拟方法,对有内热源房间内三维温度场、速度场及热舒适指标进行了数值模拟.模拟了4种典型的气流组织形式,同时在对热舒适度评价时引入了有效吹风温度EDT及气流分布性能指标ADPI.结果表明,4种气流组织形式都能满足人体对舒适度的要求,其中散流器送风方式效果最好.
Now, more and more people begin to be aware of the problem of thermal comfort degree in air-conditioning room. The three-dimensional temperature field, velocity field and thermal comfort index are numerically calculated with k - e turbulent model in the room with a hot source. Four typical air distribution forms are simulated and effective draft temperature and air diffusion performance index, which can be used to evaluate the thermal comfortable degree, are applied. The result indicates that all the four air distribution forms can meet the demand of comfortable degree of occupants and the effect of air diffuser.
