POY Finalist: Outdoor air system
Finalist in HVAC in Plant Engineering’s 2011 Product of the Year competition
The CITY MULTI VRF Dedicated Outdoor Air System is designed to supply outdoor ventilation air to a building independent of the HVAC air distribution or conditioning system. The DOAS preconditions air for introduction into downstream HVAC units, lessening the load on HVAC systems.
The DOAS connects to a VRF outdoor unit with INVERTER-driven technology to provide energy-efficient outside air by utilizing waste heat from cooling cycles to provide reheat capability without needing an additional or supplemental energy source. The DOAS also reduces utility costs when used in conjunction with HVAC systems.
