人员密度对电梯轿厢内热舒适性的数值研究

imulation about Effect of the Thermal Comfort on Person Density in Elevator

利用CFD技术对不同人员密度,不同规格的电梯轿厢内流场进行数值模拟,分析人员密度对轿厢内热舒适性的影响规律以及不同规格电梯内的热舒适性,首次针对每种规格电梯给出临界通风量。研究结果表明:轿厢内人员密度过大是造成PMV过高的主要因素,在临界通风量下,载客8人电梯随时间变化PMV增幅最小,而载客21人电梯PMV增幅最大。

The different of person density and elevator specifications is simulated by using Airpak software. According to every type of elevator critical ventilation is given. The results show that the high person density is the primary reason which results in high value of PMV in the elevator. Under conditions of critical ventilation elevator of 8 persons have the lowest increase amplitude of PMV, however, elevator of 21 persons have the highest increase amplitude with the lapse of time. The information obtained could be used as a reference for further knowing and improvement of the elevator air quality.
