VRF (Variable Refrigerant Flow) technology has progressed rapidly over the last 16 years and offers a substantial increase in energy efficiency, low running costs and reduced CO2 emissions. Many systems offer inverter controlled compressors and the latest technologies. VRV technology is the most flexible and can allow up to 50 indoor units to be connected to just 1 outdoor unit. These can include any combination of cassettes, ducted, floor, wall or ceiling mounted air conditioning indoor units. These systems have a very small footprint and are easily hidden out of sight on new builds. Advanced VRV system can provide simultaneous heating and cooling to indoor unit’s dependant on the user requirements.
