Products Description

• Mixing Section

  • Details: Fresh air (OA) and return air (RA) dampers are typically interlinked and controlled to maintain a constant total airflow (in constant volume systems). The damper actuators can be electric, pneumatic, or electronic, receiving signals from the Building Management System (BMS).

  • Key Parameter: Minimum outside air ratio (typically 15-30%, modulated based on demand control ventilation or codes).

• Filtration Section

  • Filter Grades (EN/ISO Standards):

    • G3/G4 (Pre-filters): ~80-90% efficiency on ≥5µm particles. Protects equipment.

    • F5-F9 (Medium-efficiency): 40-95% on ≥1µm particles. Standard for commercial IAQ.

    • H10-H14 (HEPA/Sub-HEPA): >95% on ≥0.3µm particles. For cleanrooms, ORs, labs.

  • Differential Pressure Gauge/Switch: Monitors pressure drop across the filter bank. Alerts when the filter is loaded and needs replacement—critical for preventive maintenance.

• Coil Section

  • Construction & Materials:

    • Tube & Fin: Copper tubes with mechanically expanded aluminum fins. Often coated with a hydrophilic (water-loving) film to improve condensate drainage and inhibit microbial growth.

    • Rows/Circuits: Cooling coils are typically 4-8 rows deep. More rows increase dehumidification capacity. Internal circuits (for water or refrigerant) ensure even distribution and heat transfer.

    • Drip Pan: Located below the cooling coil. Must be sloped, insulated, and equipped with a proper P-trap to ensure condensate drainage and prevent air leakage and microbial contamination.

• Humidification Section

  • Type Details:

    • Steam Humidification (Isothermal): Most common. Uses clean, dry steam from a central boiler or self-contained generator, injected via a steam dispersion manifold. Precise and hygienic.

    • Adiabatic Humidification: Uses high-pressure water nozzles or ultrasonic atomizers. Cools the air as water evaporates (adiabatic process).

• Fan Section

  • Fan Types:

    • Forward-Curved Centrifugal Fans: Lower pressure, higher volume. Common in smaller units.

    • Backward-Inclined/Airfoil Centrifugal Fans: Higher efficiency, non-overloading power curve, quieter operation. Preferred for large, efficient AHUs.

  • Drive Arrangement: Belt-driven (adjustable, requires maintenance) or direct-driven (higher efficiency, lower maintenance).

  • Variable Frequency Drive (VFD): Standard on modern AHUs. Modulates fan speed based on duct static pressure or temperature reset strategies for significant energy savings in part-load conditions.
