Air Supply Units with Temperature and RH Control

Air supply units (ASUs) equipped with precise temperature and relative humidity (RH) control are critical components in various industries and environments. These units ensure optimal conditions for products, processes, and human comfort.

Components and Function

Typically, an ASU with temperature and RH control comprises:

  • Air handling unit (AHU): This core component filters, heats, cools, and humidifies the air.

  • Temperature sensors: Accurately measure the air temperature.

  • Humidity sensors: Monitor the relative humidity level.

  • Control system: Regulates the AHU's operation based on set points and sensor readings.

  • Heating and cooling coils: Adjust the air temperature as needed.

  • Humidification and dehumidification systems: Control the moisture content in the air.

How it works:

  • Air intake: The ASU draws in outside air or recirculates indoor air.

  • Filtration: Impurities are removed through filters of varying efficiency.

  • Conditioning: The air is heated or cooled to the desired temperature and humidified or dehumidified to achieve the target RH.

  • Distribution: The conditioned air is supplied to the designated areas through ductwork.

Key Considerations

  • Precision: Accurate temperature and RH control is essential for many applications.

  • Energy efficiency: Selecting energy-efficient components and optimizing system operation is crucial.

  • Maintenance: Regular inspection and maintenance are required to ensure optimal performance and reliability.

  • Redundancy: Backup systems may be necessary for critical applications to prevent disruptions.

Applications

ASUs with temperature and RH control find applications in:

  • Industrial processes: Maintaining precise conditions for manufacturing, pharmaceuticals, electronics, and food processing.

  • Commercial buildings: Ensuring occupant comfort and indoor air quality in offices, hospitals, and data centers.

  • Data centers: Protecting sensitive equipment from overheating and humidity-related issues.

  • Cleanrooms: Providing a controlled environment for manufacturing critical components.
