COOLSENSE

The Trane® CoolSense™ Integrated Outdoor Air System combines a dedicated outdoor air system (DOAS) with chilled-water, sensible-cooling terminal units to deliver a flexible, energy efficient solution.

Closer Look: How it Works

  • The sensible-cooling terminal unit utilizes conditioned outside air from the dedicated outside air unit.

  • Cool and dry ventilation air is modulated and measured using an airflow-measuring damper.  

  • A variable-speed fan with ECM draws in air from the plenum through a sensible-only cooling coil.

  • Chilled water is supplied from the dual-temperature chiller plant to this sensible-only cooling coil.  Remember chilled water supplied to this cooling coil is below the space dew point temperature to ensure the coil is only removing the sensible (dry heat) load. 

  • The conditioned ventilation and recirculation air mix in the fan compartment and is then delivered to your space

  • Optional hot-water or electric heat is available to act as zone level heating.

  • To ensure proper operation, the unit is equipped with a factory-mounted and pre-programmed UC400 unit controller

Dual-Temperature Chiller Plants 

This Engineers Newsletter describes several dual-temperature chiller plant configurations that can provide two temperatures—one cool enough to provide sensible cooling but warm enough to avoid condensation, and the other cold enough to dehumidify.
