Exhaust Function: Exhaust systems remove stale indoor air, odors, and moisture, reducing indoor pollutant levels and ensuring fresh, healthy indoor air. Exhaust also helps regulate indoor temperature and humidity, improving indoor comfort.
Supply Function: Supply systems bring in filtered, heated, or cooled outdoor air, providing ample oxygen and reducing indoor carbon dioxide concentration. Fresh air also helps eliminate odors and improve indoor air quality.
The main functions and effects of exhaust systems include:
1. Promoting Air Circulation: Expelling stale air and introducing fresh air, preventing carbon dioxide buildup, and quickly removing fumes, water vapor, and odors.
2. Reducing Pollutants: Diluting harmful gases such as formaldehyde and benzene, reducing PM2.5 concentration, and controlling the spread of pathogens.
3. Regulating Temperature and Humidity: Accelerating heat dissipation in summer, preventing excessive dryness in winter, and inhibiting mold growth in damp spaces.
4. Reduce disease transmission: Lowering the probability of airborne diseases such as influenza and tuberculosis is especially important during pandemics.
5. Improve comfort: Maintaining fresh air, preventing confined space syndrome, and ensuring more even temperature distribution.
