Available in cooling only, heat pump and heat recovery versions, the new system, which represents aconsiderable advance over earlier VRV systems, demonstrates Daikin’s innovative application of new technology and the latest HFC refrigerants to itsVRV product programmes.6-4-4 Less waste and improved re-cyclingThe lead free, soldered PCB obviates environmental contamination, whilst the re-cyclable galbarium steel bottom plate is designed to last around 6 timeslonger than the traditional galvanised base.6-4-5 Refrigerant recovery functionThe refrigerant recovery function enables all expansion valves to be opened. In this way the refrigerant can be drained from the piping system andstored in the receiver and the condenser.18 HP Comparable VRF systemTotal refrigerant amount in the system* 100 % 160 %NOTE* based on average installation16 HP R-22VRV-K seriesR-407CVRV-K seriesR-410AseriesRefrigerant charge 100 % 85.6 % 79.5 %Reductionof 20.5 %
