通过数值模拟研究了不同风口设置及室内布局情况下,医院输液室内的气流组织和病人散发的带菌颗粒物的运动分布特征。结果表明,不同挡板高度对气流组织的影响较大,尤其对人员附近局部区域的空气品质和污染物扩散方式有一定的影响。结合医院输液室室内布局的实际情况,对风口处气流组织进行了分析,并提出了合理的风口设计方案。
Through the numerical simulation, the airflow distribution in the hospital infusion room and the distribution characteristics of the particles carrying the patient with different tuyere settings and indoor layout were studied. The results show that the influence of different baffle heights on the air flow structure is significant, especially on the air quality and pollutant diffusion modes in the local area near the personnel. Combined with the actual situation of the indoor distribution of the hospital infusion room, the airflow organization at the tuyere was analyzed and a reasonable design of tuyere was proposed.
