Daikin Applied Launches New Heat Pump Technology Smartsource
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.
