 Here are the types of ventilation: 1. Natural Ventilation:  Uses natural airflow, wind, and temperature differences to ventilate buildings. 2. Mechanical Ventilation:  Employs fans, blowers, and ducts to circulate and exchange air. 3. Hybrid Ventilation:  Combines natural and mechanical ventilation strategies. 4. Forced Ventilation:  Uses fans to force air into or out of buildings. 5. Exhaust Ventilation:  Removes stale air and pollutants from buildings. 6. Supply Ventilation:  Introduces fresh air into buildings. 7. Balanced Ventilation:  Provides equal rates of exhaust and supply ventilation. 8. Displacement Ventilation:  Introduces fresh air at floor level, displacing stale air upwards. 9. Task Ventilation:  Provides ventilation specifically for workstations or tasks. 10. Spot Ventilation:  Focuses ventilation on specific areas or sources of pollution. 11. Heat Recovery Ventilation (HRV):   Recovers heat energy from exhaust...

  The purpose of ventilation is to: 1. Remove stale air:  Exchange stale air for fresh air to improve indoor air quality. 2. Control humidity:  Regulate moisture levels to prevent mold growth and condensation. 3. Reduce odors:  Eliminate unpleasant smells and gases. 4. Remove pollutants:  Extract airborne contaminants, such as dust, pollen, and chemicals. 5. Heat recovery:  Recover heat energy from exhaust air and transfer it to fresh air. 6. Cooling:  Provide cooling through evaporation or convection. 7. Air circulation:  Circulate air to prevent stagnation and promote even temperatures. 8. Pressure control:  Regulate air pressure to prevent damage to buildings and improve comfort. 9. Indoor air quality (IAQ) improvement:   Maintain healthy indoor air quality by removing contaminants. 10. Compliance with regulations:  Meet local building codes, regulations, and standards for ventilation. 11. Energy efficiency:  Optimize energy...
