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 Plan
We 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 Utilization
The 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 Time
The 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 System
The 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 Changes
Indoor 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 Night
The 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°.
