An innovative, patented, world-first technology
The world’s only two-pipe Hybrid Variable Refrigerant Flow (VRF) system that exchanges heat between refrigerant and water using our unique Hybrid Branch Circuit (HBC) Controller, which reduces the use of refrigerant on the outdoor side and keeps the indoor space refrigerant-free.
Exclusive cutting-edge technology
This breakthrough simultaneous heating and cooling technology incorporates the efficiency and heat recovery benefits of a VRF system with the additional comfort and control of a 4-pipe chiller system by utilizing hydronic indoor units.
Hybrid VRF outdoor units exchange heat between refrigerant and water using our proprietary Hybrid Branch Circuit (HBC) Controller by a two-pipe refrigerant system, allowing for simultaneous heating and cooling while reducing the overall refrigerant charge in the system and keeping the piping in the indoor space refrigerant-free. Mitsubishi Electric leads the industry in HVRF technology and a best-in-class warranty.
Simultaneous hydronic heating and cooling
Hybrid VRF creates a refrigerant-free closed loop to heat and cool occupied spaces.
Modulating hot or chilled water flow from an HBC Controller to indoor units heats or cools every space to maintain exceptional comfort.
Heated or chilled water flows from the heat exchangers through a 3-way valve block to allow for use in any zone. The system is designed for a low delta-T water design with active water temperature reset for effective seasonal comfort.
Scalable design, affordable installation
Reduced refrigerant and materials equals reduced cost.
Save on installation cost and labor by eliminating refrigeration work between the HBC Controller and Hybrid VRF indoor units. Hybrid VRF allows for traditional copper water piping or Multi-layer composite piping to be used between the HBC Controller and Hybrid VRF indoor units.
Our unique 2-pipe heat recovery system requires less piping than a 4-pipe chiller system. In addition, the system does not require an external pump, valves, sensors, actuators, or other ancillary controls associated with conventional 4-pipe chiller systems.
Hybrid VRF features
Flexible
Compatible with a wide range of air- or water-source units connect to the Hybrid Branch Controller (HBC) by a two-pipe refrigerant system, allowing for simultaneous heating and cooling.
Faster installation with a smaller footprint
Hybrid VRF uses the same CITY MULTI® N-Generation outdoor units as VRF with a newly added capacity range ensuring a more efficient installation that requires less space.
Efficient performance
Can be installed indoors, so efficiency is not impacted by extreme outdoor temperatures. Plus, the HBC Controller reduces refrigerant charge and can share energy between systems on the condenser loop.
Exponentially scalable
Flexible enough for any application with a modular design system. As a result, it is just as scalable as traditional VRF systems and a perfect fit for any size building.
Future-proof sustainability
Can reduce refrigerant volume to easily change to lower global warming potential (GWP) refrigerants. Hybrid VRF offers a lower carbon footprint than traditional HVAC systems.
