The VRVIII®-S completes the mix of
VRV systems offering by allowing the
technology to be available at smaller
capacities. An air-cooled heat pump
condenser with 1-phase power supply
(208-230V), connects to a maximum of
six indoor units for the 3-Ton and eight
indoor units for the 4-Ton model. The
versatility of the VRVIII-S makes it ideal
for most light commercial or residential
projects - retail stores, small offices,
restaurants, hotels, healthcare facilities,
schools, multi-family townhouses, condos
or single-family homes.

Light commercial
Whether you are working with space constraints or
want to maximize the amount of commercial space
available, the VRVIII-S system gives you the flexibility
you need. With its simple, versatile design and long
piping (up to 492ft actual piping length one way),
the VRVIII-S can accommodate practically any floor
layout, enabling better use of space.
Its advanced zoning capabilities allow floor-by-floor
installation so that each floor can be occupied quickly
upon completion. And, because the outdoor units
are lightweight and vibration-free, there’s no need to
reinforce floors, reducing both installation time and
costs.
Residential
VRVIII-S is also an excellent alternative when building
a new house or renovating. Its long piping length
allows for multiple floors to be served from one
condenser installed outside.
All indoor units come with fan speed control and
operate extremely softly — as low as 28 decibels, the
equivalent of rustling leaves.
Outdoor units have built-in noise-reducing features,
including an automatic night mode function that lowers
the sound level for any period of time specified.
A feature of particular importance for residential
applications is the ‘night set’ mode, which can be set
on site to function over a 9 hour period during which
operating sound is reduced progressively in three
increments of 3dB(A).

The VRVIII-S system is a highly efficient solution
for small commercial buildings requiring heating
and cooling of up to 8 zones. A mix of ducted and
duct-free indoor units can be combined to provide
individual comfort and ease of installation. Imagine
a small office application with the reception, the
meeting room, the president’s office; all part of
the same system but yet able to have different set
temperatures or being shut off without affecting
other areas, realizing tremendous energy savings
compared to traditional centralized systems.

Intelligent to the core
At the core of the VRVIII®-S system
is built-in intelligence that gives you
independent zoning control with
maximum flexibility and energy
savings. With the ability to connect
up to eight indoor units to one
outdoor unit, the space-saving
VRVIII-S system is ideal for most
light commercial or residential
projects.
VRVIII-S Features:
n
All major components of the VRVIII-S
outdoor units are engineered and
manufactured by Daikin to ensure
maximum performance, efficiency
and Absolute Comfort

Noise-Reducing Air Inlet Bell
Mouth & Aero Spiral Fan. Bell
mouth guides and bent-edge fan
blades also reduce turbulence.
DC Fan Motor. Improves
efficiency compared to
conventional AC motors, especially
during low-speed rotation.
Super Aero Grille. Spiralshaped ribs align with direction
of discharge flow to minimize
turbulence and reduce noise.
Reluctance Brushless DC
Compressor. Significantly
increases efficiency over AC
inverter motors by using both
normal and reluctance torque
to produce extra power from
small electric currents.
Single-phase technology is perfect
for light commercial and residential
applications in 36,000 and 48,000
Btu/h models.

Smaller capacity allows precise
temperature control over every square
inch of space.

The 7S for Success Concept
n
Soft sound level operation ensures
a comfortable fit in any room.
n
Single-supplier reliability. The
system - factory engineered and
80% complete upon delivery - is
fully optimized by Daikin, plus has
self-Diagnostics and one of the
best warranties in the industry.
n
Straightforward maintenance and
service with self diagnosis function.
Superior energy efficiency results in
lower operating costs especially under
partial load conditions.
e-Bridge Circuit. Increases
evaporative capacity by adding
super cooling prior to expansion
cycle. This prevents accumulation
of refrigerant in the condenser for
greater energy efficiency.
