15 ALL Variable refrigerant temperature How does it work? The higher the refrigerant temperature, the higher the efficiency The lower the capacity need, the higher the refrigerant temperature can be The colder it gets the lower the cooling need of the building Seasonal efficiency Outdoor temperature Capacity & load in cooling mode Refrigerant temperature 20° 25° 30° 35° The biggest leap since the inverter compressor Thanks to its revolutionary variable refrigerant temperature technology (VRT), VRV continuously adjusts both the inverter compressor speed and the refrigerant temperature in cooling AND heating, providing the necessary capacity to meet the building load with the highest efficiency at all times! VRF standard Capacity is controlled only with the variation of the inverter compressor. Daikin VRV Variable Refrigerant Temperature control for energy saving in partial load condition. The capacity is controlled by the inverter compressor and variation of the evaporating (Te) and condensing (Tc) temperature of the refrigerant in order to achieve the highest seasonal efficiency. Evaporating temperature can vary between 3 and 16° which is the widest on the market. Cooling requirement Design point Adjust capacity by Te control to meet the load (avoid over capacity and ON/OFF operation) Efficiency with Variable Refrigerant Temperature J Seasonal efficiency increased by 28% J The first weather accommodating control on the market J Customer comfort is assured thanks to higher outblow temperatures (preventing cold draughts) Fixed Te Variable Te Efficiency up System capacity
