Presentation Transcript

  1. Dedicated Outdoor Air System (DOAS) in HVAC • Improving Indoor Air Quality and Efficiency • Your Name / Organization • Date

  2. Introduction to DOAS • - A Dedicated Outdoor Air System conditions only the outdoor air for ventilation. • - Separate from space temperature control systems. • - Improves IAQ and dehumidification.

  3. Why DOAS? • - Traditional HVAC systems mix ventilation and conditioning. • - Issues with humidity control and efficiency. • - DOAS benefits: • • Better IAQ • • Energy savings • • Enhanced comfort

  4. How DOAS Works • - Conditions outdoor air (filter, cool, dehumidify). • - Delivers air to zones or terminal units. • - Works with parallel systems for temperature control.

  5. Key Components • - Outdoor Air Intake • - ERV / Heat Recovery Wheel • - Cooling & Heating Coils • - Dehumidifier • - Supply Fan • - Ductwork

  6. Types of DOAS Configurations • - DOAS with: • • Variable Refrigerant Flow (VRF) • • Chilled Beams • • Fan Coil Units • • Radiant Systems

  7. Advantages of DOAS • - Superior humidity control • - Reduced mold risks • - Improved energy efficiency • - Flexible zoning • - Enhanced comfort

  8. Energy Recovery in DOAS • - Use ERV/HRV to recover energy from exhaust air. • - Reduces heating/cooling load. • - Saves operational costs.

  9. Applications • - Schools and universities • - Hospitals and healthcare • - Commercial offices • - High-performance and LEED buildings

  10. Challenges • - Initial cost • - Space for ductwork and equipment • - Maintenance needs • - Integration with current systems

  11. Case Study / Example • - Building with DOAS implementation • - Results: • • Improved IAQ • • Energy savings • • Occupant comfort

  12. Conclusion • - DOAS = smart choice for healthy, efficient buildings • - Separates ventilation from temperature control • - Ideal for green and sustainable designs

  13. Q&A • Any Questions?
