VEGAS - The City Multi® VRF
dedicated outside air system (DOAS) from Mitsubishi Electric Cooling and
Heating Solutions was
named the AHR Expo Innovation Awards Product of the Year.
unit supplies outdoor ventilation air to a building independent of the HVAC air
distribution or conditioning system. It accepts up to 100 percent outside air
at temperatures ranging from -4°F to 109°F WB, preconditioning up to 1,200 cfm
of air for introduction into downstream HVAC units.
City Multi VRF DOAS can be installed whenever 100 percent outside air
processing is required, a typical installation would utilize the split system
configuration in applications where a large package system is less feasible.
Depending on the requirements of the supply air, a reheat system, which uses
waste heat from the primary cooling coil to reheat and provide 45 percent rh
air ranging from 63° to 83°, or a non-reheat system would be installed.
Multi VRF DOAS was introduced in 2010 and is widely available.
