LAS 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.
The 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.
While the 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.
The City Multi VRF DOAS was introduced in 2010 and is widely available.
