通風是COVID-19大流行給我們的課題

Ventilation is a Lesson from COVID-19 Pandemic

COVID-19疫情突然爆發，讓全球重新審視疾病預防的重要性，尤其強調了公共衛生與環境控制的角色。我們認為有效的疾病預防不能只依賴藥物，而需要建立健康的生活環境與習慣。空氣流通在阻止空氣傳播病原方面尤為重要。我們提出了通風的三大核心概念：通風是有進有出、阻抗決定路徑、以及必須從乾淨到不乾淨(clean to less clean)的方向流通。這些概念旨在建立一個具方向性的空氣流動，確保污染物向下游排出，減少傳染風險。有效的通風需考慮空間設計、格局與空氣流動的路徑，避免氣膠在密閉空間中累積。居家環境的通風也需注意佈局、減少阻礙，並可藉由二氧化碳感測器等設備監控空氣質量。總結來說，COVID-19大流行，提醒我們應正視通風對健康的重要性，維持良好的空氣品質，進而增強防疫效果與居住安全。

The unexpected COVID-19 pandemic has led the world to reconsider the importance of disease prevention, especially highlighting the roles of public health and environmental control. We believe that effective disease prevention cannot depend solely on medication but requires building healthy environments and habits. Airflow is crucial in preventing airborne transmission of pathogens. We propose three core concepts for ventilation: intake and exhaust, resistance determines the path, and clean to less clean. These concepts aim to create directional airflow, ensuring pollutants are directed downstream and reducing transmission risks. Effective ventilation requires attention to space design, layout, and airflow paths to prevent aerosol buildup in enclosed spaces. In the home, good ventilation reduces obstructions and can be supported by devices like CO2 sensors to monitor air quality. In summary, COVID-19 has reminded us of the importance of ventilation for health, maintaining good air quality, and enhancing infection control and residential safety.
