LG Electronics (LGE), a digital leader, has launched its new Multi F DX commercial air-conditioning system, designed for three-phase power use.

The Multi F DX is an upgrade from the Multi F system, which was originally created for domestic buildings, connecting up to four indoor units to one outdoor unit.
By using distributor boxes, each bridging up to four indoor units, the Multi F DX can connect up to nine indoor units to one outdoor unit. The installer can choose the indoor units from LG’s wide range of residential air conditioners, including its popular picture-frame-style indoor unit, Artcool, said a spokesman.
The new Multi F DX will be introduced to global markets with four different capacities: including 9.7 kW, 12.3 kW, 14.1 kW, and 15.2 kW. Long piping up to 145 m and elevation up to 30 m allows flexible installation, easily adapting to a building’s architecture.
The system includes a DC inverter compressor, which reduces the energy consumption of the air-conditioning system using advanced technology. (See also Page 87)
