Mitsubishi Electric US Inc. Cooling & Heating Division has introduced its CITY MULTI ceiling cassette indoor unit, featuring the 3D i-see Sensor. The sensor is mounted to the exterior panel of the ceiling cassette and continuously analyzes the thermal profile of a room, identifying cool and warm spots. When a room is occupied, the sensor identifies heat signatures and applies cool or warm air as needed. The feature may be customized to deliver air toward or away from occupants. In an unoccupied room, the sensor automatically adjusts the temperature levels and may be customized to switch to an energy-efficiency mode. The unit is available in capacities ranging from 8,000 to 48,000 Btu per hour.
