Optimised R-410A design - VRVII & VRV-WII
Daikin Europe has achieved a quantum leap forward in commercial air conditioning technology by the introduction of its VRVII, the world’s first R-410A
operated variable refrigerant flow system. Available in cooling only, heat pump and heat recovery versions, the new system, which represents a
considerable advance over earlier VRV systems, demonstrates Daikin’s innovative application of new technology and the latest HFC refrigerants to its
VRV product programmes.
4-4
Less waste and improved re-cycling - VRVII
The lead free, soldered PCB obviates environmental contamination, whilst the re-cyclable galbarium steel bottom plate is designed to last around 6 times
longer than the traditional galvanised base.
4-5
Refrigerant recovery function - VRVII & VRV-WII
The refrigerant recovery function enables all expansion valves to be opened. In this way the refrigerant can be drained from the piping system and
stored in the receiver and the condenser.
