【摘要】 本文针对电梯轿厢热舒适性较差这一问题,使用CFD商用软件分析了电梯轿厢内通风的气流组织情况;文中着重分析了轿厢内热舒适性,指出轿厢内温度过高是导致其PMV值过大的主要原因。通过对增加风量和采用不同的通风方式对改善电梯轿厢内热环境的数值模拟比较,发现当送风量为原送风量的4倍时,可将轿厢内的PMV值由原来的2.65改进为2.05,将上送风改为上排风且风量为原送风量的两倍时,可将PMV值改进为2.03。更多还原

【Abstract】 In this paper,the airflow in the elevator is simulated by CFD software to analysis the reason why the thermal comfort of elevator usually is in a low level,and especially thermal comfort of environment in the elevator is analyzed.The high temperature is the primary reason which results in high value of PMV in the elevator.Through the compare of the result of numerical simulation between increasing the wind rate and adopting different mode of ventilation,it was found that the value of PMV improve from 2.65 to 2.05 when wind rate is 4 times of original one,and that the value of PMV is 2.03 when the ventilation is changed from supply to exhaust on the ceiling and the wind rate is double of original one.更多还原
