More and more often in projects, I need a system that does not use refrigerant in the building. Ideally, a modular design is possible, which helps me comply with standards in the future.

The unique City Multi Hybrid VRF system

Simultaneous or alternating cooling and heating with minimum use of refrigerant through a water-based internal circuit. Extend your lead!

Choose from two Hybrid VRF system variants

Hybrid VRF as R2 system
Simultaneous heating and cooling with heat recovery

The R2-series enables simultaneous heating and cooling via a two-pipe system and the Hybrid BC-Controller. With the R2 variant, each individual indoor unit within the Hybrid VRF system can be independently operated in heating or cooling mode. The heat from the areas needing to be cooled is used to heat other locations within the same building.

Hybrid VRF as Y system
Cooling or heating

The Hybrid VRF Y-series enables cooling or heating mode based on the heat pump function that is integrated as standard. In the Y-series, a hydro unit featuring an integrated plate heat exchanger is used to exchange energy between the refrigerant and the water. The inverter-controlled pump then ensures that the tempered water is sent to the indoor units in line with demand.

Significantly reduced refrigerant volume

With the Hybrid VRF system, the refrigerant is used only in the outdoor unit and in the Hybrid BC-Controller or the hydro unit. This makes it possible to implement projects that require the premises to be free of refrigerant lines. The use of water as a heat transfer medium means that DIN EN 378 does not apply in individual rooms. And the use of R32, which transfers more energy with less mass, generally results in the need for less refrigerant than a system with R410A.

Flexible planning

The Hybrid VRF system offers maximum flexibility in terms of the use, distribution and selection of functions of rooms and also enables seamless connection to the higher-level building management system.

Simultaneous heating and cooling with heat recovery

With an R2-series Hybrid VRF system, each individual indoor unit can operate independently in heating or cooling mode. The heat drawn from the areas needing to be cooled is used to heat other areas in the building. The economical solution for high demands for efficiency, comfort and convenience e.g. in office buildings and hotels.

High energy efficiency

The YNW generation of City Multi outdoor units with state-of-the-art inverter compressor technology, large-area microchannel aluminium heat exchangers and many other enhancement guarantee high seasonal energy efficiency.

Lead in design

Wide range of indoor units

The wide range of indoor units within the Hybrid VRF system enables climatisation in any kind of premises.

Simple installation and maintenance

All important hydraulic components are already implemented in the Hybrid VRF system. The only task that remains is to determine the expansion tank. Plastic pipes instead of copper pipes can be installed within the building. Since the indoor units need no extra check the leak testing according to F-gas regulation is much easier to perform.

More climate-friendly

The Hybrid VRF system impresses with its high level of energy efficiency, providing optimum support in terms of meeting the current guidelines for modern, sustainable construction.

Communication via M-Net data bus

Simple and uncomplicated management with Mitsubishi Electric system control – all communication takes place via M-Net data bus. There is no need to retrofit additional communication technology.

All values and percentage-based improvements are stated in comparison with the previous series. The units contain the fluorinated greenhouse gas R410A or R32.
