The new Y series City Multi outdoor units have been developed with a focus on seasonal efficiency, resulting in improved efficiency levels in cooling and heating mode respectively.
This has been made possible by the use of a new and innovative aluminium flat tube heat exchanger with an enlarged heat transfer surface and lower pressure drop.
Mitsubishi Electric is the world’s first manufacturer to equip a VRF system with this technology. The high-efficiency compressor is a further innovation, the characteristic line of which has also been optimised for outstanding seasonal efficiency. The outdoor unit has a variable evaporation temperature, that is to say that the evaporation temperature rises as soon as the room temperature approaches the set point.
