This study considers the effects of ventilation system using the residential facilities to the transmission mechanism of indoor aerosol in the residential quarantine period space for infective diseases. This study focuses on the effect of the design of ventilation system on the internal flow field and the removal of contaminant pollution. A computational fluid dynamics software-FLUENT 6.2 is employed to simulate the internal airflow field of the residential quarantine period space. The Carbon dioxide (CO2) is adopted as the index of contaminant source. Three layouts of ventilation system are simulated and the airspeed field, the temperature distribution, and the contaminant distribution are analyzed to find the best ventilation system for the residential quarantine period space.

本研究考虑传染性疾病在居家隔离空间使用一般家用环境控制设备时对室内的气悬感染会有何影响，本文主要分析不同通风设计时对居家隔离空间内部气流之影响，并将国内外现有的规范设计方式做一系列之比较以供参考，并以商用套装软体FLUENT6.2分析居家隔离空间内部流场分布情形，模拟中以二氧化碳（CO2）作为病患所呼出含有病菌空气的指标，模拟案例分为三种主要的通风模式，并分析速度、温度与污染物浓度分布情形，以得到最佳的居家隔离空间通风配置方式。
