Introduction ED34-862
ii Introduction
1. Introduction
Preface
Along higher quality building environment and more sophisticated building function, there is now a greater demand
for system expansion for a flexible air-conditioning system capable of finer air-conditioning, thus increasing
importance of individual air-conditioning systems. On the other hand, due to social significance of environmental and
energy problems, elements such as energy-efficiency and low maintenance are still strongly desired.
Daikin is the sole air conditioning company in the world that manufactures every component from refrigerant to
complete air conditioning systems itself. Our commitment to offering the best for people as well as the environment
inspires us to develop new systems that make the most effective use of energy resources.
Daikin, the first in the industry to develop the VRV system, has now enhanced the R-410A, R-22 with the
Inverter that features an upgraded capacity of up to 54 horsepower to further refine all the features of the
current VRV system.
This publication contains a variety of information related to the design and installation of this new VRV System. We
hope this information will serve to deepen your understanding of the system, and will help you to efficiently develop
its highly evolved characteristics.

Caution
1. Air conditioners should not be installed in areas where corrosive gases, such as acid gas or alkaline gas, are
produced.
2. If the outdoor units is to be installed close to the sea shore, direct exposure to the sea breeze should be avoided.

6. Features
6.1 Technologies
Daikin’s constant efforts have been devoted towards using the latest and most revolutionary technologies in the
development of the VRVIII system for large-sized buildings. The system offers larger outdoor capacities, greater energy
savings, easier installation, longer actual and total piping, and more.
VRVIII —Created to respond to the needs
of large-sized buildings
The new heat exchanger contributes to a high COP
because of an increase from 7% to 10% of the effective
length as well as an optimised e-Pass heat exchanger.

2
A higher external static pressure has been achieved—from 58. 8 Pa to 78.4 Pa—thanks to
reduced internal pressure loss, use of the new fans and the new grilles.
The area of these new fan blades has been increased and optimised for each casing. This greatly reduces pressure loss, resulting in a
higher external static pressure.
The three-bladed fan on the 10 HP unit, with a diameter of
700 mm, has been redesigned to include four blades and now
has a diameter of 680 mm. Blade area has been increased by
25%.

Blade area has been increased by 20% to increase airflow.

DC fan motor
4
Heat transfer circuit
By performing super cooling before the expansion
process, the volume of refrigerant that needs to be
circulated to the indoor units can be reduced without
lowering the evaporation temperature. This permits the
use of narrower piping.
5
Compact aero box
Realises a compact casing by stacking the Inverter and
control PCBs plus optimising the internal design to suit
airflow speed. This achieves lower noise and reduces the
power required by the large-diameter fanned outdoor unit.
• Across entire range of models (from 5 to 54 HP).
• Efficiency improvement by approximately 40% especially
at low speed.
6
Smooth sine wave DC Inverter
By adoption of the Sine
Wave, which smoothes the
rotation of the motor,
operation efficiency is
improved sharply.

Improving the high efficiency compressor to achieve

Reluctance DC scroll compressor
High torque and efficiency is attained with the adoption of
neodymium magnets. Achieves 70% reduction in volume.
Daikin’s unique scroll compressor minimises heat loss, and is driven by a high
efficiency motor to achieve significant energy savings.
By introducing high pressure oil, the reactive
force from the fixed scroll is added to the internal
force, thereby reducing thrust losses. This
results in improved efficiency and suppressed
sound levels.
High-performance, low-noise new scroll
compressor operates at a faster rate.
The speed increase has been achieved
through advanced stress analysis for
increased strength and utilisation of the
advantages (oil film control) of the high
thrust mechanism*.
