VRV Variable Refrigerant Volume is Daikin’s proprietary name for the large-scale multi-zone refrigerant system technology that is more generically known as VRF (Variable Refrigerant Flow). While VRV is a Daikin trademark and VRF is the broader industry term used by other manufacturers, the two refer to the same fundamental technology. For clarity, this page uses VRV to describe Daikin’s specific system range, which is the most widely installed VRF platform in the Australian commercial market.
Air On Temp provides VRV air conditioning installation, service, and repair across Sydney for commercial buildings, large residential properties, mixed-use developments, and any application requiring sophisticated multi-zone climate control from a single refrigerant system.
Daikin VRV is available in two main configurations, and the choice between them depends on whether the building requires simultaneous heating and cooling in different zones:
VRV Heat Pump the entire system operates in either heating or cooling mode at any given time. This is suitable for buildings where all zones typically require cooling in summer and heating in winter, without a need for simultaneous operation in different modes. VRV Heat Pump systems are simpler and generally lower cost than Heat Recovery systems.
VRV Heat Recovery individual zones can operate in heating or cooling mode simultaneously. The system recovers heat from zones being cooled and redistributes it to zones requiring heating, rather than rejecting it to the outdoor air. This is the appropriate solution for buildings with diverse occupancy and internal heat load patterns such as a building with server rooms or commercial kitchens that require year-round cooling alongside perimeter offices that need heating in winter. Heat Recovery systems deliver measurably lower energy consumption in these applications.
A Daikin VRV system uses a variable-speed compressor to modulate the flow of refrigerant to multiple indoor units simultaneously, with each zone independently controlled. This distinguishes it from conventional multi-split systems in several important ways:
System design and quotation
We review the building layout, zone requirements, and pipe run constraints. A detailed system design and fixed-price quotation is provided covering equipment, pipework, and commissioning.
Programme planning and compliance
We develop the works programme, prepare required SWMS documentation, and coordinate with the principal contractor or building manager for site access.
Equipment and pipework installation
Outdoor units, indoor units, and the complete refrigerant pipework network are installed to Daikin specification. All pipe runs are brazed, pressure-tested, and documented.
Commissioning and handover
The system is vacuumed, charged, and commissioned per Daikin’s procedure. Zone control and BMS integration are configured and tested. As-installed documentation is provided on completion.
VRV installation is a technically demanding scope that requires both Daikin system knowledge and the mechanical skills to install the refrigerant pipework correctly across what are often large and complex buildings. Air On Temp handles the complete VRV installation scope in Sydney, including the refrigerant pipework network that is central to system performance.
VRV refrigerant pipework involves larger pipe diameters and more complex branching than conventional split systems. Pipe sizing calculations are critical undersized pipe runs cause pressure drops that reduce system capacity, while oversized runs increase material cost unnecessarily. The branching headers (refnets) that distribute refrigerant to multiple indoor units must be installed in the correct orientation and position for the system to distribute refrigerant properly. All pipework is brazed to Australian Standards, pressure-tested at the correct test pressure for the system, leak-tested, vacuumed, and commissioned in accordance with Daikin’s specific procedures.
