HVRF Indoor Units

Why Choose a City Multi Hybrid VRF System?

City Multi Hybrid VRF indoor units connect to the Hybrid Branch Controller (HBC) using water as the heat transfer medium, eliminating refrigerant from occupied spaces. Our comprehensive range, from ceiling cassettes and ducted systems to wall-mounted and floor console models, delivers flexible solutions for offices, hotels, retail, healthcare facilities, and heritage buildings. Some of the benefits of Hybrid City Multi VRF air conditioning include:

Industry-Leading 2-Pipe Hybrid VRF Technology

Mitsubishi Electric City Multi Hybrid VRF is an industry-first technology that revolutionises VRF systems by combining the benefits of both VRF and chilled water systems. This innovative approach transfers the refrigerant between the outdoor unit, the HBC, and water for indoor distribution. This creates a unique two-pipe hybrid system that sets new standards for comfort, safety, and efficiency in building climate control.

Enhanced Safety Through Advanced Design

The system’s distinctive design eliminates refrigerant from occupied spaces by using water between the HBC and indoor units, ensuring full compliance with AS/NZS 5149 standards. Removing the need for refrigerant leak detection systems makes it particularly suitable for sensitive applications such as healthcare facilities, schools, and hotels, where occupant safety and regulatory compliance are critical.

Efficient Operation with Superior Comfort

Available in both air-cooled and water-cooled configurations, with R410A or R32 refrigerant options, the system delivers exceptional energy efficiency through heat recovery during simultaneous cooling and heating operations. The water-based distribution system provides naturally stable temperatures and milder off-coil temperatures, ensuring consistent comfort across all zones while simplifying installation compared to traditional 4-pipe systems. Comprehensive control options, including centralised building management systems and individual controllers, enable optimised application performance.
