VRV IV sets the standards…again
Dubai, 21st June 2015
Daikin Middle
East & Africa has launched its 4th Generation of VRV IV for high
ambient markets. Launch Event was attended by more than 250 key
consultants, Developers, Distributors & Industry professionals from
across the GCC, and was held at the Sofitel Down Town – Dubai.
VRV IV achieves a
new benchmark for efficiency, as it features major enhancements to the
already industry-leading VRV solution. VRV IV offers three revolutionary
innovations: variable refrigerant temperature (VRT), Refrigerant –
cooled PCB, and the VRV configurator for simplified commissioning.
Daikin has been
continuously setting the standards for climate control since it first
introduced the VRV technology in 1982. This major innovation created a
whole new category in the air conditioning market for Variable
Refrigerant Flow systems. Innovations, such as inverter controlled
compressors have improved efficiency and comfort and made VRV one of the
fastest growing specified systems in the commercial and residential
buildings. More than 40% of the VRF systems installed in GCC are Daikin
VRV systems.
The unique
Variable Refrigerant Temperature (VRT) technology allows VRV IV heat
pumps to respond to cooling requirements by continually monitoring the
required capacity and weather conditions. This automatic adjustment
means the system only uses the power required to meet the load,
resulting in 28% less energy being consumed, derived from higher part
load efficiencies, when compared with previous generations of VRV and
standard VRF systems.
Variable
refrigerant technology (VRT) allows the installer to customize the
system using a choice of presets, to optimize the energy and comfort
balance for the individual project. In automatic mode, the system is
configured for the highest efficiency levels throughout the year, while
allowing rapid response on the hottest days, ensuring comfort at all
times. This technology delivers 28% increase in seasonal efficiency,
because the system continually adjusts the refrigerant temperature
according to the total required capacity and the external weather
conditions.
The VRV IV core
technologies result from over 50 patents related to the Compressor,
Condenser Coil, and amongst all; the Refrigerant –Cooled PCB which adds
reliability at the high ambient temperatures in the GCC.
The new VRV
configurator completes the trio of innovations and offers an advanced
software solution which simplifies commissioning and customization. This
means less time is required on the roof configuring the outdoor unit.
Ongoing maintenance is easier too, thanks to a graphical interface that
allows engineers to evaluate operational data and errors. The VRV
configurator also allows multiple systems within multiple sites to be
managed all in exactly the same way, thus offering simplified
commissioning and easy maintenance for key accounts.
“Daikin's VRV IV
has become even smarter; not only it is especially equipped to handle
the sizzling heat of the Middle East, but with its unique VRT technology
it constantly monitors ambient temperature and continuously adjust not
only the refrigerant flow like typical VRF systems, but also the
refrigerant temperature to achieve maximum efficiency and minimum power
consumption”, said Mr. Nabil Shahin, Product Development Director at
Daikin Middle East & Africa.
To complement
the VRV IV system, Daikin’s new intelligent touch manager offers an
intuitive user interface with a visible floor plan and provides energy
management tools to maximize efficiency.
The system has
an option to integrate through “I-Net”, a predictive and preventive
maintenance application. The system operates by remotely monitoring the
operation of the major components and identifying any deviation from
the norm as a potential future failure, and hence sends a message to
service to take care of the problem before it happens.
The VRV IV
system can be used together with a wide range of decorative and
concealed indoor units, using state of the art inverters for higher
levels of comfort and lowest energy consumption. The
combination with Air Handling units and factory designed controls makes
it the system of choice to meet Fresh Air requirements in high
performance buildings.
The VRV IV
Performance has been third party tested to ensure the highest level of
Performance at 35°C and 46°C (T3) and continuous operation at very High
Ambient Temperatures of 55°C using ISO and AHRI testing standards to
meet current and scheduled upcoming regulations such as ESMA, SASO and
MEW regulations.
"From my point
of view the new VRV IV is now fully adapted to the harsh environment of
the GCC market, the reliability is massively improved based on the
refrigerant cooled PCB, the protection layers on the electronic boards,
and the special PE coating on the coil. In addition to adding the VRT
control to the VRV IV, we are now already prepared for future regulation
demands on seasonal efficiency showing our commitment towards the
region" said Mr. Patrick Crombez, EU Strategic Marketing Department
Manager, EMEA Development Center at Daikin Europe NV.
