Design flexibility
VRVIII-S systems offer broad design flexibility with long refrigerant piping lengths and
multiple indoor unit combinations, which provides generous freedom for office and shop
design both inside and out.
MAIN FEATURES
For a 6 class (15.5 kW) installation
Multiple indoor unit combinations are possible. * As many as 9 indoor units can be connected
to a 6 class (15.5 kW) unit, making the VRVIII-S a versatile system.
* Total capacity index of connectable indoor units must be 50 - 130 % of the capacity index of the outdoor unit.
Up to 9 indoor units can be
connected to a single outdoor unit
The VRVIII-S provides the long piping length
possibility of 150 m, with a total piping length
of 300 m. If the outdoor unit is installed
above indoor units the level difference can
be up to a maximum of 50 m. These
generous allowances facilitate an extensive
variety of system designs.

Note:
The operation range of the VRVIII-S system works to
reduce limitations on installation locations. The
operation temperature range for heating goes all the
way down to -20°C, while cooling can be performed
with outdoor temperatures as high as 46°C. Both these
achievements are due to the adoption of a high-
pressure dome-type compressor.
