Heating, ventilation and air conditioning, Variable Refrigerant Flow (VRF) technology does it all. Prioritising room comfort, reduced energy consumption and lower maintenance costs, state-of-the-art VRF systems are designed to exceed all expectations.
Created in Japan in 1982 by technological pioneers Daikin, VRF was a world first, using variable refrigerant flow to control cooling and heating. Conditioned by a single outdoor condensing unit, the system circulates refrigerant within a building to multiple fan-coil units to create heat and coolness, providing an efficient alternative to traditional water-based systems. The variable flow of the refrigerant means the system is only required to work as needed and provides greater control over a building’s interior temperature, offering energy savings of up to 55% compared to other systems.
Two system formats are available. The two pipe design keeps it simple, either cooling or heating all or required zones. Alternatively, those requiring a sophisticated system that can simultaneously heat and cool separate areas can use a Heat Recovery (HR) system, which is achieved through a three pipe design by extracting heat from areas that need to be cooled for use in areas requiring heat.
Over 30 years since the innovative design was unveiled, the benefits of VRF systems continue to make it the most popular product on the market. With increased efficiency, greater flexibility and an improved compact design, VRF systems offer numerous benefits compared to more traditional heating, ventilation and air conditioning systems. From offices to hotels, schools to shops, VRF provides improved thermal control of any building, allowing individuals to manipulate the temperature and provide optimal comfort.
