10 Years of Hybrid VRF by Mitsubishi Electric – the World’s First Hybrid VRF System
The World’s First Hybrid VRF System
Ten years ago, Mitsubishi Electric changed the course of the HVAC industry by introducing the world’s first City Multi Hybrid VRF (HVRF) system – a true technological revolution.
For the first time in history, the advantages of systems using refrigerant as a heat transfer medium and those using water were combined into one innovative solution, which remains unique on the market to this day.
Separate Refrigerant and Water Circuits – an Intelligent Hybrid Principle
The City Multi Hybrid VRF system made Mitsubishi Electric a pioneer in hybrid VRF technologies. The term “hybrid” describes the integration of two different principles in order to extract their key advantages. In this case, the characteristics of systems using refrigerant and water as heat transfer media are combined, organised into separate circuits.
The result is a significant advantage: The refrigerant does not circulate inside the building, ensuring greater safety, sustainability, and design flexibility.
Energy-Efficient and Adaptive HVRF Systems for Modern Architectural Projects in Bulgaria
HVRF technology is designed with modern buildings in mind—those that require a high standard of comfort and optimal energy efficiency.
It represents a sustainable and future-oriented solution that meets increasing environmental requirements while providing the freedom for modular and flexible design of systems using water circulation as the heat transfer medium.
This makes it possible to build complete heating and cooling installations that integrate renewable energy sources—all within a single, intelligent system.
