Daikin Middle East & Africa has launched its fourth generation of VRV IV for high ambient markets.

More than 250 key consultants, developers, distributors and industry professionals from across the GCC attended the recently held launch event 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.

It offers three innovations – variable refrigerant temperature (VRT), refrigerant – cooled PCB, and the VRV configurator for simplified commissioning.

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 per cent 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) will allow the installer to customise the system using a choice of presets, to optimise 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 per cent 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 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 customisation. This means less time will be required on the roof configuring the outdoor unit. Ongoing maintenance will be easier owing to a graphical interface that will allow engineers to evaluate operational data and errors.

The VRV configurator will also allow multiple systems within multiple sites to be managed all in exactly the same way, thus offering simplified commissioning and easy maintenance for key accounts.

Nail Shahin, product development director at Daikin MEA, said: “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.”

To complement the VRV IV system, Daikin’s new intelligent touch manager will offer an intuitive user interface with a visible floor plan and provides energy management tools to maximise 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-degree C and 46-degree C (T3) and continuous operation at very high ambient temperatures of 55-degree C  using ISO and AHRI testing standards to meet current and scheduled upcoming regulations such as ESMA, SASO and MEW regulations.

Patrick Crombez, EU strategic marketing department manager, EMEA Development Centre at Daikin Europe NV, said: ”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.”
