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.
