Daikin Applied introduced the Daikin SmartSource Dedicated Outdoor Air System (DOAS), its next generation of heat pump heating technology that enables efficient and cost-effective heating and cooling in all conditions using 100 percent of fresh, outside air. The new unit features exclusive SmartBoost Heat Technology, which allows for air as cold as 0 degrees Fahrenheit to enter without any pre-heating, all while achieving 49 percent higher than ASHRAE 90.1-2016 minimum efficiency.

The SmartSource DOAS taps a water source heat pump's hot gas reheat coil in addition to the unit's primary DX coil. The resulting heating efficiencies - up to 5.1 ISCOP2 per AHRI 920-2020 - coupled with the latest advancements in electronically commutated motors and industry-leading shaftless blower technology help ensure premium performance.

Other key features of the new SmartSource DOAS include:

  • Multi-stage, uneven compressor tandem that provides eight stages of heating and cooling control, ranging from 100 percent to 30 percent operating capacity.
  • Programmable options for either constant or variable airflow control, ranging from 70 to 200 percent of nominal airflow, and external static pressures over 2 inches achieved at nominal unit airflow.
  • Incorporation of Daikin's new, BACnet-enabled MicroTech controller, which marries advanced unit control, built-in control logic and smart safety features with a user-friendly interface. The controller automatically selects between heating, cooling or dehumidification modes of operation, and its dynamic control can achieve discharge air temperature accuracy within one degree under steady conditions.
