Dedicated Outdoor Air System: Mitsubishi Electric U.S. Cooling & Heating Division

Mitsubishi-090213-body.jpgMitsubishi Electric U.S. Cooling & Heating Division is now offering the CITY MULTI® VRF Dedicated Outdoor Air System. The system is designed to supply outdoor ventilation air to a building independent of the HVAC air distribution or conditioning system. According to the company, the DOAS is unique because of its energy efficiency, and it can use the heat recovery feature to provide “free” reheat. The DOAS pre-conditions outside air for introduction into downstream HVAC units, lessening the load on HVAC systems. Because the HVAC systems have to work less to condition the air to a certain temperature when used in conjunction with the DOAS, end-users can save on utility costs. The DOAS connects to a Mitsubishi Electric VRF outdoor unit with INVERTER-driven technology to provide energy-efficient outside air by using waste heat from cooling cycles to provide reheat capability without needing an additional or supplemental energy source.  Available for use in new construction or retrofit commercial applications, the DOAS accepts 100% outside air at temperatures ranging from -4ºF WB up to 109ºF WB, preconditioning up to 1,200 cfm of air for introduction into downstream HVAC units.
