Unité de contrôle de température et d'humidité de précision
A close-control air-conditioning unit that coordinates cooling, reheat, humidification and airflow to hold stable cleanroom temperature and moisture conditions.
- Coordinated Cooling and Reheat
- Stable Humidity Control
- Modulating Airflow
- Remote Monitoring Ready
Introduction de produit
The precision temperature and humidity control unit responds to small thermal and moisture changes that conventional comfort equipment may ignore. A modulating cooling stage removes sensible heat and moisture, reheat prevents overcooling during dehumidification, and humidification adds controlled moisture during dry conditions. Direct-drive fans maintain airflow through filter loading, while separate temperature and humidity sensors support stable control. The unit is suited to laboratories, metrology rooms and clean processes with narrow operating bands.
Key Features
Modulating valves, inverter compressors or staged circuits provide finer response than simple on-off control.
Remote supply and return sensors can distinguish room conditions from local unit casing effects.
Trendable alarms for temperature, humidity, airflow and filter loading support early intervention.
Préoccupations du client produit
Tight environmental control requires all heating, cooling, humidifying and airflow functions to respond as one system rather than as independent devices.
Dehumidification lowers room temperature below the operating band.Modulating reheat offsets the sensible cooling remaining after moisture removal.
Oversized on-off cooling cycles cause repeated humidity swings.Variable or staged capacity matches smaller loads and reduces short cycling.
A sensor near the supply outlet does not represent the controlled workspace.Remote room sensors and averaged feedback are positioned at representative locations.
Filter loading changes airflow and alters coil moisture removal.Fan-speed control maintains airflow while differential-pressure monitoring signals service need.
