Mitsubishi Electric Australia has expanded its Hybrid Variable Refrigerant Flow (VRF) system from eight-branch connections to 16. A world-first simultaneous heating and cooling 2-pipe system that uses refrigerant between the outdoor unit and the HBC (Hydro BC controller), and water between the HBC and the indoor units, the Hybrid VRF gets a boost with the latest enhancement. The most unique part in this system, the HBC, allows heat exchange between the refrigerant and water.

The Hybrid VRF system allows simultaneous cooling and heating, offering heat recovery between indoor and outdoor units running on opposite modes. Two refrigerant pipes connect the outdoor units to the HBC, and a pair of plastic water lines runs out to each indoor unit, allowing energy-saving heat recovery operation. Smooth auto-switching (heating and cooling) based on a set temperature provides convenient operation and a comfortable environment. This system is suitable for a wide variety of installations.

Raja Gounder, Deputy General Manager Business Development, Mitsubishi Electric Australia explains that the Hybrid VRF system operates without using refrigerant in occupied spaces, eliminating any need for leak detection equipment and allowing more buildings to take advantage of manageable phased installation through the system’s modular design.

According to Gounder, the use of water has the added benefit of more stable temperatures coming out of the indoor units. For these reasons, Hybrid VRF is the ideal air conditioning solution for hospitals, hotels, and offices. Temperatures are more stable during defrost as the system uses the heat of the hot water that circulates between the HBC and the indoor units. Defrost time is shorter compared to conventional systems.

Hybrid VRF is available through Mitsubishi Electric Australia distribution channels.
