FEATURES
·
Constant-Speed outdoor units for
two-way Multiset V.R.F. systems
·
To be installed as secondary units
and to be matched with primary DC Inverter units
·
R410A HFC refrigerant
·
High efficiency Scroll 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 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
·
A special fan made of resin allows
to reduce the sound level of the outdoor units
·
A special resin grille has been
designed and used for these units in order to minimize air pressure drops and
consequently reduce the outdoor sound level of 4 dB
·
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 +5°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
