Hitachi Air Conditioning Units for Small Public Buildings

An overview of Hitachi's R32 air conditioning solutions for small public buildings, featuring wall-mounted, ducted, and cassette units with advanced technology and flexible installation options.

Wall Units for Small Public Buildings

These wall units offer multiple features to fit various setups, providing efficient and comfortable climate control.

Key Features

  • 4-Way Swing: Distributes air uniformly for improved room comfort by moving blades vertically and horizontally.
  • Motion Sensor: Saves energy by continuously analyzing room occupancy. It shifts the setpoint by one degree after 20 minutes of no detection and by another degree after 40 minutes.
  • Improved Comfort: Allows selection of the temperature measurement point (remote control, return air, or average) for enhanced comfort.
  • Flexible Installation: Supports a long cooling pipe (up to 30m) and a significant level difference (up to 20m) between indoor and outdoor units.
  • Compact Indoor Unit: Measuring 900mm wide, it allows for installation without interfering with room elements.
  • Compatibility: Works with the Hi Kumo remote controller for remote operation via a mobile app.
