Mitsubishi Electric has launched a new air conditioning unit that claims to use less refrigerant than traditional Variable Refrigerant Flow (VRF) systems.
The HVRF system operates without using refrigerant in occupied spaces, so removing the need for leak detection equipment and allowing properties to take advantage of phased installation through the system's modular design.
At the heart of the new system is a (Hybrid Branch Controller) HBC box, 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.
Mary Grayson of Mitsubishi Electic, explained: "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.
This legislation is particularly applicable for hotels, where legislation limits systems to about 20Kg of R410a or forces the addition of leak detection systems.
