Future-proofing your air conditioning

Today’s buildings face tough legislation which means that traditional HVAC technologies may not always be the best solution

Hybrid VRF

Hybrid VRF is the latest addition to the Mitsubishi Electric City Multi family (the VRF range of air-conditioning units for large scale applications)

 

Offering true integration for a huge range of constructions, Mitsubishi Electric’s Hybrid VRF is perfect for today’s modern, airtight buildings, combining the comfort of a traditional chiller with the efficiency and ease of modern VRF air conditioning. The result: a unique, patented, world first technology – which really does give you the best of both worlds.

What is Hybrid VRF

Hybrid VRF is the latest addition to the Mitsubishi Electric City Multi family (the VRF range of air-conditioning units for large scale applications). Built and assembled in the same factory as our VRF units thereby carrying its distinctive DNA in terms of technology, efficiency and reliability.

Put simply, Hybrid VRF is a 2-pipe heat recovery VRF with water between the Hybrid Branch Controller (HBC) and indoor units. You can install and design it as VRF whilst enjoying the features of a Chiller system.

Providing a complete modern solution for office buildings, hotels, medical centres, schools, high rise buildings, shopping centres and other commercial premises.

Hybrid VRF is quick, easy & flexible to design and install using the same control and network as VRF systems. Furthermore the decentralised system means phased installation is possible with the same high levels of seasonal efficiency expected with VRF. With water at the indoor units, Hybrid VRF provides comfortable and stable air temperature control with no refrigerant in occupied spaces, meaning simple compliance to BS EN378 and removing the need for leak detection.

The award-winning R32 Hybrid VRF solution

With the familiarity of a VRF system and the water-based performance of a chiller, our latest Hybrid VRF models use low GWP refrigerant R32. Already used in a variety of Irish buildings over the past 5 years, Hybrid VRF provides a future proof design solution. As a modular system, it also allows for easy installation on both new builds and retrofit. This technology continues to set the standard for comfort, performance and energy efficiency for today’s modern and air tight buildings.

Buildings around Ireland have a high priority when it comes to energy efficiency, internal comfort and an easy control solution. We believe there is no limitation with Hybrid VRF and the possibilities are endless.

Hotel applications

Customer comfort is paramount with legislation focusing attention on energy use and seeking to limit the use of refrigerant in occupied spaces. Hybrid VRF removes the need for leak detection thereby reducing the total cost of the system and on-going maintenance of the leak detection systems itself.

Hotel customers have high demands when it comes to comfort and control whilst hotel owners have strict legislation to adhere to and costs to minimise.

Mitsubishi Electric City Multi VRF is an ideal solution for hotel applications due to its efficiencies - simultaneous heating and cooling with heat recovery, flexible control solutions, high seasonal efficiency and its modular design and installation.

Mitsubishi Electric’s Hybrid VRF system addresses 2 major issues in the air conditioning industry: refrigerant volume and adherence to BS EN378. The amount of refrigerant in the system is greatly reduced, only being used in the pipework from the VRF heat recovery outdoor unit to the Hybrid Branch Controller. This minimises the use of greenhouse gases within the system, making it a more environmentally friendly than traditional VRF systems, says Fergus Daly, MIRI ACIBSE M.ASHRAE, Mitsubishi Electric.

Secondly, BS EN378 requires refrigerant leak detection technology to be present in all occupied spaces. However, with Hybrid VRF using water to serve indoor units instead of refrigerant, this requirement is no longer needed. Not only does this make the system more cost-effective, but it also means it is suitable for many applications, including hotels.


Hybrid VRF offers an integrated solution both now and into the future.
