Pengenalan Produk

A dedicated outdoor air system separates ventilation and latent treatment from the high recirculation airflow used for cleanroom particle control. It receives 100% outdoor air, recovers useful energy from a separated exhaust stream where appropriate, cools and dries the air, then reheats it to a neutral or designed supply condition. This division lets terminal recirculation units handle sensible load and filtration without relying on them to remove the full outdoor-air moisture load. Airflow, dew point and supply temperature can be monitored independently.

Ciri-ciri Utama

Ventilation airflow is measured independently from cleanroom recirculation air changes.

Deep dehumidification establishes a predictable supply dew point across seasonal outdoor conditions.

Plate, run-around or carefully selected rotary recovery can reduce outdoor-air heating and cooling load.

Reheat prevents overcooled ventilation air from causing local discomfort or excess sensible cooling.

Kebimbangan Produk Pelanggan

When ventilation air and recirculation air are treated together, moisture control can drift as outdoor conditions and room sensible loads change independently.

The cleanroom becomes humid at low sensible load even though space temperature is stable.The DOAS controls outdoor-air dew point separately from room recirculation cooling.

Ventilation quantity is inferred from a damper position rather than measured.An airflow station and fan control maintain the scheduled outdoor-air volume.

Energy recovery risks transferring contaminants from exhaust to supply.A separated plate or run-around system is selected where cross-stream leakage cannot be accepted.

Cold dry ventilation air overcools perimeter or low-load rooms.Modulating reheat delivers a neutral or scheduled supply-air temperature after dehumidification.
