Air Handing Unit

Features at a Glance

•  Air Mixing & Proportioning

  • Purpose: To balance energy efficiency with indoor air quality (IAQ).

  • How it Works: Dampers automatically adjust the ratio of outside fresh air and indoor return air. This allows for "free cooling/heating" using return air to save energy while ensuring sufficient fresh air intake for occupant health and ventilation requirements.

•  Air Filtration & Purification

  • Purpose: To protect downstream equipment and improve IAQ by removing contaminants.

  • How it Works: Air passes through a series of filters.

    • Pre-filter: Traps large particles like dust and lint, protecting coils and fans.

    • Medium-efficiency filter: Removes finer particles (e.g., pollen, mold spores), common in commercial buildings.

    • High-efficiency/HEPA/Chemical filters (Optional): Used in critical environments like hospitals and labs to remove PM2.5, bacteria, viruses, or gaseous pollutants.

• Air Temperature & Humidity Control

This is the core conditioning process, achieved via heat exchangers and humidifiers.

• • Cooling & Dehumidification: Air passes over a cooling coil carrying chilled water (~7°C) from a chiller or direct-expansion refrigerant. The air cools below its dew point, causing moisture to condense and drain away.

  • Heating: Air passes over a heating coil carrying hot water from a boiler or using electric resistance elements.

  • Humidification: In dry climates or during winter, a humidifier (steam, ultrasonic, or evaporative) adds precise moisture to the air.

• Air Movement & Distribution

  • Purpose: To provide the motive force for airflow and deliver it to the occupied spaces.

  • How it Works:

    • Fan: The "heart" that provides the pressure to move air through the ductwork. Modern AHUs use Variable Frequency Drive (VFD) fans to modulate airflow based on demand, saving significant energy.

    • Silencer/Attenuator: Reduces noise generated by the fan and airflow.

    • Conditioned air is then distributed quietly and evenly to rooms via ductwork and diffusers.

•  Energy Recovery (A Key Feature in High-Efficiency AHUs)

  • Purpose: To dramatically reduce heating and cooling energy consumption.

  • How it Works: A heat recovery device (e.g., heat wheel, plate heat exchanger) is placed where the exhaust air and fresh intake air streams cross. It transfers thermal energy from the exhaust air to pre-condition the incoming fresh air, potentially reducing loads by over 60%.

Products Description

• • Fan Section: The "heart" — provides the motive force to move air.

  • Filter Section: The "cleaning station" — contains pre-filters and finer filters to ensure air cleanliness.

  • Coil Section: The "conditioning station" — uses hot water or steam coils for heating, and chilled water or refrigerant coils for cooling/dehumidifying.

  • Humidifier Section: Adds moisture to the air when required.

  • Mixing Chamber with Dampers: Controls the proportions of fresh and recirculated air.
