FEATURES
·
DC Inverter Outdoor units for two-way Multiset V.R.F. systems
·
A new series of Outdoor units caracterized by:
- compactness,
making units easier to position;
- smaller pipeworks,
making material costs lower;
- flexibility of
installation;
- high efficiency
(C.O.P.at the top of the range: 3,90 average cooling/heating for the 8HP units)
- reduced life cycle
costs;
- accurate capacity
control;
- possibility to
choose among a wide range of control options.
·
Maximum number of Outdoor unuts connectables: 3.
·
Maximum total power of the system: 135 kW ( 48 HP).
·
Maximum number of Indoor units connectable: 40.
·
Twin Rotary DC Inverter compressor, highly efficient at low rotation
frequencies;R410A HFC refrigerant.
·
Fan with direct current motor that allows a consumption reduction of
about 50% and a speed modulation up to 16 steps in spite of the usual 4 steps
of the alternate current motors; this performance increases the efficiency of
the thermodynamic system which is able
to best adapt to the variations of temperature and thermal load of the
rooms.
·
The use of a special oil sensor allows, for the first time in the world,
to keep under control the lubrification of the mechanical parts of the
compressor.
·
Special air intakes and Double Chamber construction technology allowed
to unify the dimensions of the units, making easier the closing up for multiple
installatios in which two units can be placed at a distance of only 10 cm one
from the other, the smaller distance available.
·
Low sound level thanks to a special fan made of resin and a particular
resin grille, designed and used for these units in order to minimize air
pressure drops.
·
New high efficiency Cross-Arranged heat exchanger with three-way
suction, divided in two sections with double control of defronsting cycle.
·
Pressure control automatic and by software on PC.
·
Pipe connession inside the unit frame through a special space to be
closed back when the installation is finished
·
Equipped with Fault-Tolerant system granting in multiple installations
the operation of the air conditioning system also in case of total stop of one
condensing unit.
·
Support to Long-Life system that, in multiple installations, allows a
cyclic use of the condensing units, granting a balance of the compressors
activity.
·
Wide range of outdoor air temperature: from -10°C to +43°C in cooling
mode and from -20°C to +15°C in heating mode.
·
Maximum lenght of the refrigerant circuit extended to 300 m.
·
The refrigerant circuit doesn't require distribution apparatus
downstream of the unit as it can be realized with a tree structure using only
the special distributor accessories; this feature facilitates any type of
system widening, by adding both outdoor and indoor units.
·
Three-phase autosense power supply 380-415/3N/50Hz.
