Daikin Australia has launched the latest addition to its flagship VRV range, the 6th generation VRV H Series, which introduces a host of enhancements in design, capacity, installation convenience, reliability, comfort and energy efficiency.
With a focus on space-saving and application flexibility, the new system has been engineered to accommodate both single and multi-module configurations. This intelligent design minimises the overall space required for mechanical equipment and reduces the number of electrical and piping connections.
The result, the company says, is unparalleled adaptability during building design, the ability to scale up capacity through phased installation as needs evolve, and the restoration of valuable leasing space for owners and occupants of existing buildings.
For starters, single modules start at 8HP and are now offered in three chassis sizes, thanks to the introduction of a XL chassis available in an impressive 22HP and 24HP capacity.
Remarkably compact at just 1750mm wide x 765mm deep x 1660mm tall, the XL chassis achieves a four per cent reduction in total footprint and weight compared to the 5th generation VRV Series.
In terms of scalability, up to three single modules can be seamlessly combined to deliver a total capacity of up to 60HP.
The new VRV H incorporates the latest hardware and software innovations, resulting in a significant boost in energy efficiency.
At the heart of the system is the patented High Efficiency P-Type Compressor, engineered for optimal part load performance. Also, with an understanding part load EER (at 50 per cent load) of up to 6.55, this compressor delivers an impressive efficiency improvement of up to 29 per cent when compared to Daikin’s 5th generation model.
Taking energy savings to the next level is the VRT Smart II Control, a cutting-edge technology developed by Daikin. This state-of-the-art system enhances efficiency during operation by intelligently regulating the air volume of the indoor unit, and adjusting the refrigerant temperature of the compressor along with the outdoor unit fan speed in response to the indoor heat load.
The company says that this meticulous optimisation process ensures both building comfort and minimal energy consumption, providing an ideal balance between occupant satisfaction and sustainability.
Refrigerant piping lengths of up to 165m are possible, offering greater flexibility in system design. Additionally, the maximum height difference between the indoor and outdoor units has been extended to 110m, surpassing the 5th generation model by 20m.
These advancements further enhance the suitability of the VRV H system for large-scale buildings, providing increased versatility and improved adaptability.
The enhanced sealed electrical box design of the system features an ingress protection rating of IP55, providing protection against dust and moisture. The company says that with the addition of a new service window, accessing the multi-functional digital display for commissioning and troubleshooting has never been easier.
Furthermore, the system incorporates separate wiring and piping makes for a swift and straightforward installation, offering convenient access when needed. These advancements not only provide protection against environmental factors, but also prioritise user-friendly functionality, facilitating efficient maintenance and seamless operation.
Built-in refrigerant-cooled inverter PCB, featuring three strategic cooling points of contact, enables seamless operation even in high-temperature environments.
With the innovative design, the system, can operate up to a maximum ambient temperature of 52°C, and the technology ensures efficient cooling of the inverter PCB, guaranteeing reliability and longevity even in challenging conditions.
