FEATURES
·
DC Inverter outdoor units for
three-way Multiset V.R.F. systems
·
Automatic change-over between
cooling and heating modes for each indoor unit; this feature, based on the
three-way technology with heat recovery, allows a fully independent operation
of each indoor unit
·
R410A HFC refrigerant
·
Twin Rotary DC Inverter
compressor, highly efficient at low rotation frequencies, matching with a
Scroll Constant-Speed compressor
·
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 easy 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
·
"On Demand" feature
allows to best use the caracteristics of DC Inverter
technology, setting three different levels of electric power on which are
automatically based the control microprocessors so that to achieve the maximum
performances with reduction of electric consumption
·
Extra range of outdoor air
temperature: from -10°C to +43°C in cooling mode and from -20°C to +15,5°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
