Decarbonisation driven by Daikin’s R-32 VRV 5 heat recovery solution
Actively promoting decarbonisation, Daikin’s VRV 5 Heat Recovery climate control system has been purpose-engineered to meet the demands of modern buildings, while also minimising its environmental impact.
Presently, heating and powering buildings in the UK represents a staggering 40% of the UK’s total energy usage, and as the UK has committed to achieving net zero by 2050, the time for action is now.
While supporting effective decarbonisation of buildings is paramount and the priority, the importance of generating comfortable and healthy environments cannot be understated. Daikin’s VRV 5 Heat Recovery system has been purpose built with these goals in mind. For the climate control solution, the latest evolution of the VRV (Variable Refrigerant Volume), a technology that was first developed over 40 years ago by Daikin, places a focus on the reduction of both direct and indirect environmental impact, while offering unmatched simplicity and versatility in design and installation.
Sustainability and system efficiency
The aim for the design of the VRV 5 Heat Recovery system was to maximise the overall operation efficiency of the system in real-world conditions. This solution achieves market-leading performance, with a 13% increase in seasonal efficiency compared to the previous R-410A generation. Additionally, Daikin’s VRV systems have just two energy transfer steps (from air to refrigerant and from refrigerant back to air), which ultimately minimises the losses and further improves the overall system efficiency.
Moreover, VRV 5 Heat Recovery has been specifically engineered for the lower Global Warming Potential (GWP) refrigerant R-32. The GWP of R-32 is just one-third of that of R-410A and also carries heat more effectively, together leading to up to a 71% reduction in the system’s potential direct carbon dioxide equivalent (CO2eq) emissions. R-32 is also a single component refrigerant, which supports the circular economy as it is easy to recover and recycle.
Complete system management and control
Daikin’s signature Shîrudo Technology allows for complete autonomy as the ability to integrate climate control in small rooms and spaces without any further considerations or field-supplied equipment offers complete system management and control.
Shîrudo Technology includes a number of factory-integrated refrigerant control measures. In the unlikely event of a refrigerant leak, it is detected immediately, and the part of the installation affected is isolated. This safety feature minimises the refrigerant that can leak and means only the units in the affected part of the system will be shut down. This combined with easy validation via Daikin’s Xpress software, means Daikin guarantees compliance with the specific IEC product standard, out-of-the-box.
Smarter climate control
The benefits of individual comfort and ease of use for the end user is also a hugely important feature of the overall system. The highly efficient 3-pipe heat recovery system, integrated into the VRV 5 Heat Recovery, allows for heating and cooling simultaneously, and delivers superior individual comfort. What’s more, it provides virtually free heating with the heat transfer system around the building.
Daikin’s mini Building Management System (BMS), the intelligent Touch Manager, provides both local and cloud-based access control, allowing building managers to control the building systems from any location via the touchscreen, Intranet or Internet. It also easily integrates climate control and third-party equipment into one system to make operation as simple as possible.
Stretch – built in flexibility
Innovation must be at the forefront of the bid for decarbonisation, particularly regarding climate control solutions that can be specified for a wide variety of buildings and installation locations. Daikin VRV 5 Heat Recovery offers best-in-class design and installation versatility. The system has an extensive temperature operation range of up to +46°C in cooling and down to -20°C in heating. It also offers the widest outdoor unit range on the market, with heating capacities up to 90kW.
To ensure the unit can be installed with ducting to the exterior, in small spaces or behind grilles, it has been designed to deliver an external static pressure (ESP) of up to 78 Pascals (Pa). It also features five low sound steps down to 40 db(A) in sound pressure to allow installation in accordance with urban planning requirements. VRV 5 Heat Recovery allows the same long piping runs as the current VRV range and even smaller pipe diameters, further reducing the required installation space.
The added value with VRV 5 Heat Recovery comes from the support Daikin provides. It offers a wide range of tools to make system design and selection simple. Daikin also provides full project and technical support through its expert teams.
Effective decarbonisation of buildings must now be a priority. A combination of performance developments and technologies means that Daikin’s VRV 5 Heat Recovery is the ideal solution for projects where environmental impact is a priority, including those aiming to achieve BREEAM, LEED or WELL accreditation.
The Daikin VRV 5 Heat Recovery units are available from the second half of September 2022. For more information visit https://www.daikin.co.uk/VRV5HR
