DC fan motor structure
These new features achieve a low noise fan with a large airflow, and realize a compact casing together with the compressor linking technology.
New shape promotes a spiral discharge airflow, resulting in reduced pressure loss.
Bending of the fan blade edge reduces turbulence, resulting in less pressure loss.
The new sub-cool feature prevents the flushing of liquid refrigerant from long piping due to the effects of SCe-bridge.�This can reduce the refrigerant volume required in piping and thereby enable a reduction in piping size.��

Conventional systems air condition a building as a whole, whereas the VRV system air conditions each room individually. Hence it is ideal for the constantly changing occupancy of a typical building. Even further, precise level control is possible that reacts to the exact conditions in each room. Individual control promotes a far more economical and efficient system.��
The lower end of the operating temperature range in heating has been extended from –15°C to –20°C.
The extended maximum piping length gives more flexibility when designing the system.��New compressor technology eliminates the need for piping calculations, which shortens the time needed for design.��
Layout changes can be made easily because the capacity of the indoor units can be up to 130% that of the outdoor units.
Outdoor units can be placed on the roof where they have no effect on the design of the building interior.
Units are designed to operate quietly, and are also equipped with a function for silent operation especially at night.
The controller is easy to operate and has many useful functions. Units can be controlled in each individual room.��
The self-diagnostic system identifies problems within the system quickly and accurately.
The Auto Restart function ensures that operation is restored with the previous settings even if the power has been shut off.��
Units are controlled in each individual room, so local malfunctions does not cause the entire system to shut down.
The lightweight, compact units can be transported using a regular lift.��
Units can be installed on each floor.��
The pipes are few in number, making layout simpler. Inspection after installation is straightforward.��
Operates over a broad temperature range
Provides superior design flexibility

Room Layout Change
Because each room is controlled individually, only those rooms
requiring air conditioning are cooled or heated. In addition,
thanks to inverter technology, the level of air conditioning can
be precisely controlled depending on the condition of each
room. High COP is achieved by employing cutting-edge
technology, contributing to smooth and economical operation.
Comfortable and Economical
The VRV II series includes a Heat Recovery type, which allows
simultaneous cooling and heating operation within the same refrigerant
circuit, conserving even more energy by recovering the heat generated
by the cooling operation and using it for heating.�
Adapts Easily to Any Floor PlanWe offer a wide lineup of outdoor and indoor units to meet the
needs of building size and interior design.
The length of refrigerant piping places very few restrictions on
design, thus allowing for greater flexibility in planning.
The DAIKIN VRV system offers low running costs, considerable savings in both energy and
space, and high reliability. The innovative inverter technology ensures sufficient air conditioning
in every stage of operation.
The VRV system can be interlocked with Daikin's energy-saving HRV
ventilation system. The HRV system exchanges heat between the
supplied air and exhausted air in order to recover the heat energy
contained in the exhausted air, thus allowing ventilation without
increasing the load on the air conditioning system. Operating the HRV
system interlocked with the air conditioning system further improves
the efficiency of air conditioning.
Efficient Space UtilizationThe VRV system can be used to develop a large-scale air
conditioning system on a single refrigerant piping circuit, thus
reducing the space required for air conditioning equipment.
Because the difference in height between the indoor unit and the
outdoor unit can be as large as 50 meters, even with a 15-story
building all of the outdoor units can be placed on the rooftop for
more efficient utilization of space.
Short Installation TimeThe Super Wiring system and REFNET Piping system greatly
simplify wiring and piping work, which, in turn, reduces installation
time and cost. Installation by each floor is possible as necessary.
Central Control SystemThe complete lineup of central control units facilitates building
large-scale, high-level central control systems that are easy to
operate and control.
Adapts Easily to Layout ChangesIndoor units can be added up to 130% of the capacity of the outdoor
unit to readily accommodate changes in floor layout. The heat
recovery series in particular automatically selects cooling or heating
in each room, according to the relationship between set temperature
and heat load, thus eliminating restriction on room usage.
High Reliability
Low Operating Sound at NightThe nighttime quiet operation function reduces sound levels at
night under two modes: Automatic—stores maximum temperature
and activates quiet operation automatically 8 hours later; and
Customized—sets start and end times manually.
Conventional VAV systems or systems comprising a fan coil and
chiller require an expensive, bulky standby system to prevent air
conditioning in the entire building from being stopped when there is
a problem in the system. The VRV system air-conditions each
room individually, allowing any possible problems affect only the
immediate system and not to require that all air conditioning be
stopped. If an outdoor unit compressor malfunctions, another
compressor takes over emergency operation. If an outdoor unit
malfunctions in an over 18 HP system, another outdoor unit provides
emergency operation until repair.
The VRV II system can duty cycle up to nine compressors to
balance compressor usage for longevity and stability. Multiple
outdoor units are switched with different starting sequences.
By employing a high-pressure dome-type compressor, the
operating range of heating has been extended from –15C° to
–20C°.

In conventional systems that use water, the size of the pipes had
to be calculated depending on the amount of water used. In the�
VRV system, however, Daikin's advanced compressor
technology eliminates the need for time-consuming piping
calculations and greatly reduces design time.
Long Piping Design
Can Be Installed for Each Floor
The refrigerant piping length between the indoor unit and
outdoor unit in one system can extend up to 150 meters and the
difference in height can be as great as 50 meters. These
generous allowances make it possible to put all the outdoor
units on the rooftop in a 15-story building. The difference in height
between indoor units in the same system can be as much as 15
meters, thus making it possible to cover four or five stories with a
single system.
Systems Requiring a Mix of Cooling and Heating Can Be Easily DesignedWhen cooling and heating must be simultaneously performed in
the same building, until now a 4-pipe fan coil system had to be
used. The VRV system Heat Recovery Series, however, satisfies
these needs with ease of design and installation.
Air Refreshing Treatment (Heat Reclaim Ventilation: HRV)
Lightweight Outdoor Units Short Design TimesLightweight outdoor units featuring minimized vibrations do not
require floor reinforcement as do conventional systems.
The HRV system exchanges heat between the
supplied air and exhausted air in order to bring
the outside air closer to the indoor temperature
and humidity conditions, thus allowing
ventilation without increasing the cooling and
heating load. And it can save not only running
cost but also initial air conditioning system's
cost because the smaller ones can be selected. �
The HRV system interlocks with the operation of
the VRV system, thus eliminating the need for a
dedicated HRV remote controller and
simplifying installation and wiring operation. The
central control unit is common to the VRV, thus
helping achieve the total control and
management of air conditioning and ventilation.
Wide Range of Control SystemsUsing regular wired or wireless remote controllers, various control
systems can be achieved including double remote control, group
control of up to 16 units and interlocked control with HRV.
By flexibly combining the central controller, on/off controller and
schedule timer, a versatile central control system can be easily
constructed to control up to 128 indoor units.
Our large-scale air conditioning management system consists of
the intelligent Manager ECO 21, which allows BMS*-level
monitoring and control simply using a personal computer, or the �
BACnet Gateway / DMS-IF (for LONWORKS®), which connects
air conditioning system to a BMS to perform monitoring and
control.�
* BMS: Building Management System�
* LONWORKS® is a registered trade mark of Echelon Corporation.�
* Refer to pages 23 and 24 for details about Advanced Controllers.
Intelligent touch Controller is a simplified but highly advanced
central control air conditioning management system that gives
complete control of your air conditioning equipment.
Daikin's VRV systems include indoor and outdoor units available in a wide variety of models for
all sizes of buildings and installation conditions. Long refrigerant piping lengths and other
features put few restrictions on design for greater flexibility in meeting the needs of the building.
Since the external hydrostatic pressure of the outdoor unit fan motor is 6 mm H2O, an outdoor unit can
be placed on each floor using short-discharge ductwork.
Lineup of heat pump types is 5 to 48 HP, and heat recovery types is 8 to 48 HP, both in 2 HP increments*. Indoor units consist of 10 types with a total of 63 models. This wide selection of models
makes it possible to build a system that perfectly suits the customer’s requirements.�

Unique piping and wiring systems and lightweight, compact indoor units make it possible for just
a few people to install a VRV system quickly and easily. The Auto Address Setting function and
the Auto Check function for piping and wiring errors allow anyone with just the ability to install
regular direct expansion type air conditioning equipment to perform a highly reliable installation.
Reduced Piping and Cost
Super Wiring System
Auto Address Setting FunctionThe address of each indoor unit is set automatically at the same
time they are connected, thus eliminating the need to manually
set each address. Address setting for central control can be
performed easily from the remote controller of an indoor unit.
Sequential StartingBy employing D -net, systems on the same power line will be
started sequentially. This holds down the starting current,
allowing the capacities of breakers to remain small (possible up
to 100 HP).
Four-Way Wiring and Piping Connection
Check Function for Connection Errors of Wiring and Piping Mistakes in piping or wiring in the system can be checked via
lamps on the printed circuit board of the outdoor unit.
Wiring can be fed from the front panel, both left and right side
panels or bottom panel of the outdoor unit. �
Piping can be fed from 4 directions, front, both left and right or
bottom of the outdoor unit. �
These features increase installation flexibility, minimizing the
space required for installation and simplifying maintenance of
the wiring and piping.�
�
Simple Wiring
Daikin's advanced REFNET piping system makes installation
easy. Only two* main refrigerant lines are required in one system,
and the strainers, stop valves, two-way and three-way valves,
used in conventional water piping systems are not required.
Thanks to the REFNET piping system and electronic expansion
valves, imbalances in refrigerant flow between units is greatly
reduced even though small-diameter piping is used. The small-
diameter piping is also easy to handle and requires less piping shaft
space. (* Three in the case of heat recovery type.)
The REFNET Joint and REFNET
Header (both optional) reduce the
amount of work involved in
installation and increases the
reliability of the system.
A Super Wiring system is used to enable the shared use of the
wiring between indoor and outdoor units and the central control
wiring. A high-level central control system can be achieved via a
relatively simple wiring operation. Even when retrofitting with a
central control system, all that is required is to connect the central
control unit to the outdoor units.
Two-wire multiplex transmission system makes it
possible to connect multiple indoor units to one
outdoor unit with one 2-core wire, thus simplifying
(Cooling) VRV System (DAIKIN PID Controls) ON/OFF controlled air conditioner (2.5 HP)
Light weight, Compact Units
Installation by FloorIf necessary, installation can be performed by floor. The
installers do not have to wait until the entire system is
installed in the building to test the system in each section.
Self-Diagnosis Function for Efficient Servicing and Maintenance The self-diagnosis function detects malfunctions in major locations in the system and displays the type of malfunction and location. This
allows servicing and maintenance to be performed more efficiently.
The VRV system is an advanced system that offers convenience and comfort for end users.
Electronic expansion valves respond to changes in load in
indoor units and continually control the flow rate of refrigerant.
In this way, the VRV system maintains a nearly constant room
temperature without the typical temperature changes that occur
with a conventional ON/OFF control system. The extremely
refined PID control maintains the room temperature within ±0.5°C of the set temperature.
Precise Room Temperature Control
Automatic Cooling and Heating SwitchingThe difference between the set temperature and actual room temperature is
detected and the cooling or heating mode is automatically switched over.
Auto Swing Low Operating Sound DesignAll indoor units have a low operating sound design.
LCD Remote ControllerThe remote controller uses an easy-to-read liquid crystal
display for easy operation. A full line of wired and wireless
controllers is available for the indoor units of all types.
Auto Restart FunctionEven if there is an extended power failure, the VRV system will
automatically restart operation. A power failure will not cause any
settings to be lost, thus eliminating the need for re-programming.
Indoor units are so lightweight and compact that they can be
installed in any ceiling space. Outdoor units do not require
special cranes or conveyors to move them. They can even be
hauled in a building elevator.
Whether it be a ceiling-mounted cassette (double- flow/multi-
flow/600 x 600 multi-flow) type, ceiling-mounted cassette corner
type, ceiling-suspended type or wall-mounted type, all these
indoor units have an Auto Swing mechanism that helps keep the
room temperature uniform.

Total load Standard ratio of power �input for outdoor unit
Modern office buildings are highly airtight and subject to an increasing heat load due to the use of computers, lighting equipment and other office equipment. In these buildings some rooms may require artificial cooling even in winter, depending on the amount of sunshine received and the number of people in the room. In order to meet such requirements the Heat Recovery Series enables the simultaneous operation of cooling and heating by controlling the BS unit that switches cooling and heating. This series also substantially improves energy efficiency by recycling exhaust heat.
• The adoption of an inverter-controlled R-HIDECS circuit has achieved an efficient exhaust heat recovery operation. This circuit enables exhaust gas generated during cooling operation to be utilized for heating operation, reducing power consumption by 15 to 20% compared with that of conventional systems.�
• Cooling and heating modes switch over automatically according to preset temperatures. The system also responds flexibly to changes in the room's heat load.
Note : Specifications are based on the following conditions;�•Cooling : (*1) Indoor temp. of 27°CDB, 19.5°CWB, and outdoor temp. of 35.0 °CDB. (*2) Indoor temp. of 27°CDB, 19.0°CWB, and outdoor temp. of 35.0 °CDB.�•Heating : Indoor temp. of 20°CDB, and outdoor temp. of 7°CDB, 6°CWB.�•Equivalent piping length : 7.5m�•Level difference : 0m�•Capacity of indoor unit is only for reference. Actual capacity of indoor unit is based on the total capacity index. (See ENGINEERING DATA for detail.)�
•Sound level : Anechoic chamber conversion value, measured under JISB8616 conditions. During actual operation, these values are normally� somewhat higher as a result of ambient conditions.

Heat Reclaim Ventilation
Note: 1.�2.�3.��4.�5.
Sound level is measured at 1.5m below the center of the body. �Air flow rate can be changed over to Low mode or High mode.�Sound level is measured in an anechoic chamber.�Sound level generally become greater than this value depending on the operating conditions, reflected sound, and peripheral noise.�The sound level at the air discharge port is about 8 dB higher than the unit's sound level.�Even when the outdoor temperature is below -15°C, the system is operable down to -20°C with the preheater installed at the outdoor air intake side.
Daikin's HRV (Heat Reclaim Ventilation) recovers heat energy lost through ventilation and holds down room temperature changes
caused by ventilation, thereby maintaining a comfortable and clean environment. This also curbs the load on the air conditioning system
and conserves energy. In addition, the HRV is interlocked to Daikin's VRV system, SkyAir and other air conditioning systems and
automatically switches over ventilation mode, further increasing the effects of energy conservation. HRV operation has been centralized
on the air conditioner remote controller allowing total control over air conditioning and ventilation with a simple configuration.

Air Conditioning Load �Reduced by Approximately 28%
1. Approximately 20% by operating in total heat exchange mode (in comparison with normal ventilation fans)�
2. Another approximately 6% gained by auto-ventilation mode changeover switching �
3. Yet another approximately 2% by pre-cool, pre-heat control
The use of the originally developed High Efficiency Paper (HEP) element and optimized design of the fan and airflow passages, has enabled the first-class compactness in the industry while maintaining some 28% reduction of air conditioning load as before. The height of the main unit has been reduced by up to 285 mm* and easily fits in limited spaces, such as behind ceilings.

Precautions
R410A applies higher pressure than R22 and uses
refrigeration oil different from R22. Therefore, piping
works and tools are also different from those for R22
refrigerants.
Branch pipe and dividing pipe for R410A are provided
specially for REFNET piping. Since these new parts are not
interchangeable with current REFNET parts, do not use
current REFNET piping materials for R410A. (Refer to the
option list)
Use C1220 type copper tube for refrigerant piping. Wall thickness
of copper tube shown in the below table can be applied. �

Refrigerant Piping Materials
Precautions for Installation Work
Procedure and Tools for Refrigerant Piping Work
Other refrigerant piping materialsREFNET piping materials
Piping work for R410A model partially differs from R22 model in items and procedures of piping work and refrigerant charging due to
different component and higher pressure for R410A. The below chart shows general work procedure for R410A model.
Several dedicated tools are required for the installation work of R410A models. Some of conventional tools can be used except tools
actually used to the installation work for R22 models.
Tools
Tool name Work process / Usage Interchangeability with conventional tool
Pipe cutting Interchangeable and can be used.
Dedicated flaring tool is required due to flaring dimension change.
Interchangeable and can be used. (Be strictly sure that oil does not flow in reverse to the unit during pump stop.)
Pipe flaring
Applying to flared sectionUse dedicated ether oil, ester oil, alkyl-benzene oil or mixture of these oils.
Dedicated torque wrench is required due to different size of 1/2 "and 5/8" flare nuts.
Dedicated gauge manifold and charge hose are required due to high pressure and prevention of intoroduction of impurities.
Previous tool cannot be used due to different refrigerant characteristics. (Measuring instrument must be used.)
Interchangeable and can be used.
Dedicated detector is required (Use detector for R410A).
Interchangeable and can be used.

Vacuum drying
Refrigerant additional charging
Gas leakage check
Since stricter caution should be necessary for R410A to
prevent intrusion of foreign matters into the refrigerant piping
line, be sure to conduct N2 blowing when brazing is required.
Other than brazing, a stricter work control including pipe
covering and drying is required to prevent pipe from intrusion of
foreign matters.
Joint brazing
Charge R410A from service port at liquid side stop value of
outdoor unit in liquid phase. At that time, conduct vacuum
drying using vacuum pump.
Refrigerant charging
Make sure to conduct air-tightness test.
Air-tightness test
Make sure to conduct chamfering (filing) at cut section, since a
large wall thickness of pipe results large burr. Be aware of no
cutting chips left inside pipe.
Apply appropriate amount of refrigeration oil on outer / inner
surface of flared section to prevent leakage. Make sure to �
use synthetic oil (ether oil, ester oil, archi-benzene oil or
mixture of those oils) as refrigeration oil.
Conduct installation work for R410A model following above mentioned piping work procedure. Otherwise, unit �
may have trouble. Refer to the "Work execution and control for R410A model" for the details on handling of R410A,
installation works and tools.
