Fujitsu introduces multi VRF system for large buildings
FG Eurofred now offers the Fujitsu Airstage V-II multi air conditioning VRF system for large buildings. Outdoor units are available in sizes from 8 to 48 hp and can have a condenser hood connected to enable them to be installed in plant rooms in high-rise buildings. These units are 20% lighter than previous equivalent models, and compressor noise has been significantly reduced by shielding the compressor compartment. Compressors have DC inverter control.
There are 11 types of indoor units, making up 49 models in total. Cooling capacities range from 2.2 to 25 kW. Total pipe length can be up to 1000 m, and a system has a maximum 150% indoor unit connectable capacity. For control purposes, the address of each indoor unit can be set automatically simply by pressing a button on the outdoor unit.
There is a wide variety of controls — individual, central or building-management system.
Auto-changeover setting allows the system to switch easily between cooling and heating. This can be done via a specific indoor unit remote controller and/or an external input control.
