Mitsubishi Electric has launched a new air conditioning unit that uses less refrigerant than traditional VRF (Variable Refrigerant Flow) systems whilst providing simultaneous heating and cooling in a simplified two-pipe design.

The HVRF system operates without using refrigerant in occupied spaces, removing the need for leak detection equipment and allowing more properties to take advantage of manageable phased installation through the system’s modular design.

At the heart of the new system is an HBC (Hybrid Branch Controller) box, which is connected to the outdoor unit via traditional refrigerant piping. Between the HBC box and the indoor fan coils, the system uses water piping but still offers high sensible cooling and stable room temperatures for maximum comfort.

“Many of our buildings have been traditionally cooled and heated through a combination of chiller technology and oil or gas boilers, but with increasing legislation on energy efficiency and the rising cost of fuel, we now need a low carbon, cost effective alternative,” explains Mitsubishi Electric’s Mark Grayston. “We have developed this new approach to answer the need for energy efficiency and internal comfort.”
