Product Overview  ——2000-70000m³/h Axial Fan Clean Room Dx Air Handling Unit AHU for Capacity HVAC System

Modular Air Handing Unit

Key Characteristics&Core Functions

• Exceptional Air Filtration

  • Multi-Stage System: Pre-filters (G4/F5) → Medium-efficiency (F7/F8) → Terminal HEPA/ULPA (>99.99% @ 0.3/0.12 µm).

  • Performance Monitoring: Differential pressure sensors track filter loading for predictive maintenance.

• Stringent Airflow & Pressure Control

  • High Airflow: Delivers very high air change rates for rapid contaminant dilution.

  • Advanced Control: Employs CAV/VAV valves and VFD fans for dynamic air balance.

  • Pressure Cascades: Maintains defined pressure gradients (e.g., +15 Pa, +10 Pa) to enforce unidirectional airflow and zone isolation.

• Precise Temperature & Humidity Control

  • Tight Tolerances: Maintains stability within narrow bands (e.g., ±0.5°C, ±5% RH).

  • Deep Conditioning: Uses deep cooling/desiccant dehumidification and clean-steam humidification.

  • Reheat Requirement: Essential for temperature correction post-dehumidification; a major energy consumer.

•  Superior Construction & Hygiene

  • Airtight Design: Prevents infiltration of untreated air.

  • Sanitary Interiors: Smooth, crevice-free, corrosion-resistant materials (e.g., stainless steel).

  • Dry Design: Sloped condensate pans ensure complete drainage to prevent microbial growth.

• Energy Efficiency Focus

  • Heat Recovery: Incorporates enthalpy wheels or plate heat exchangers to reduce cooling/heating loads by preconditioning outside air, lowering operational costs.

Main Components&Functional Sections

1. 1. Mixing Box Section

      • Function: To mix outdoor fresh air (Outside Air) with recirculated indoor air (Return Air) in a controlled ratio to maintain indoor air quality and energy efficiency.

      • Key Components: Motorized dampers for outside, return, and exhaust air, often interlocked for proper pressure control.

   2. Filtration Section

      • Function: To remove airborne particulates (dust, pollen, microbes).

      • Filter Types:

        • Pre-filters (G3-G4): Protect downstream coils and components.

        • Medium-efficiency filters (F5-F8): Used in offices, hospitals, and general commercial spaces.

        • High-efficiency filters (HEPA, ULPA): Used in cleanrooms, operating theaters, and critical environments.

   3. Thermal Conditioning Section

      • Function: The core for controlling air temperature and moisture.

      • Key Components:

        • Cooling Coil: Uses chilled water (e.g., 6°C supply, 12°C return) or direct-expansion refrigerant to cool and dehumidify air.

        • Heating Coil: Uses hot water, steam, or electric heating elements to heat air.

        • Humidifier: Adds moisture. Common types: Dry steam injectors, adiabatic humidifiers (e.g., high-pressure mist), and electrode/ resistive steam humidifiers.

   4. Fan Section

      • Function: Provides the mechanical energy to move air through the unit and the entire duct system. It is the "heart" of the AHU.

      • Key Types: Centrifugal fans (forward or backward curved).

      • Configuration: Draw-through (fan after coils, preferred for even air distribution and coil drainage) or blow-through (fan before coils).

      • Control: Almost always equipped with a Variable Frequency Drive (VFD) for variable airflow and energy savings.

   5. Auxiliary Sections

      • Sound Attenuators: Lined sections or silencers to reduce fan and airflow noise.

      • Heat Recovery Section: Devices like enthalpy wheels, plate heat exchangers, or run-around coils to recover energy from exhaust air and precondition incoming outside air, significantly improving efficiency.

      • Plenum / Flow Straightener: Ensures uniform airflow across filters and coils.
