摘要
针对新型通风方式——层式通风,测量不同换气次数条件下办公室呼吸区位置的气流组织,主要测量温度、速度及浓度,并根据测量结果对呼吸区热舒适度进行研究。结果表明:5次较6次换气次数条件下呼吸区温度、污染物浓度以及风速更优;PMV及PPD的计算结果表明,5次换气次数条件下,呼吸区具有更佳的热舒适度。研究结果对层式通风在工程应用和相关理论研究中具有重要的指导意义。
On account of a new type of ventilation,stratum ventilation, tests air distribution in a model office with different air changes, the measure parameters in the experimental study including temperature, velocity and concentration, and studies the thermal comfort in breathing-zone. The experimental results show that, with 5 air changes, the temperature, concentration and velocity in breathing-zone are better than with 6 air changes. The results of PMV and PPD indicate that with 5 air changes, the thermal comfort in breathing-zone is always better. The experimental study is instructive for the development of the stratum ventilation.
