Mitsubishi announces 'industry leading' VRF technology

Mitsubishi Electric has announced the launch of its City Multi YLM VRF, featuring the world’s first VRF aluminium heat exchanger.

The company is claiming the YLM delivers annual energy savings of up to 27 per cent, compared with previous equivalent City Multi systems.

It also includes selectable increased and automated evaporating temperature control, optimised design of refrigerant circuit and components and the ability to provide heat during defrost.

Units are available to deliver from 22 - 101kW capacity to a building in both heat pump and heat recovery variants, with up to 50 indoor units connectable to the largest model.

The flat-tube aluminium micro-channel heat exchanger in VRF systems is claimed to deliver 26 per cent more contact with the refrigerant and 30 per cent more piping per area.

Furthermore, it is said to reduce weight and footprint and offers 10 per cent less system refrigerant volume than previous mdoels.

The company will officially launch the City Multi YLM VRF at the forthcoming Chillventa show in Germany, later this month.
