What is VRV?
VRV stands for Variable Refrigerant Volume, also known in the wider industry as variable refrigerant flow (VRF). A VRV/VRF system is still the only commercial system that continuously adjusts the refrigerant volume within the system to match exactly the heating or cooling requirement in each area, for optimum comfort and maximum energy efficiency.
Daikin VRV provides an innovative solution for climate management that optimises comfort and control, while reducing environmental impact and delivering significant energy savings. VRV has the answer to some of the key challenges for the indoor climate such as how can:
- an integrated heat recovery approach reduce running costs and CO2 emissions
- comfort be maximised without wasting energy?
- a climate control system be tailored to exact building needs?
A whole building solution
Utilising highly efficient heat recovery, VRV offers an integrated approach to heating, cooling, ventilation and hot water within medium to large buildings. This approach means that waste heat from indoor units in cooling mode can be re-used to produce hot water or provide heat to other rooms, offering major increases in energy efficiency and reductions in carbon emissions.
Complete control for maximum comfort and energy efficiency
VRV offers complete control to create the perfect temperature, fresh air flow and humidity balance. Its modular design and advanced selection software means that you can select exactly the right mix of units and options, to match your exact building requirements. A zone by zone control approach means that you can adjust individual comfort settings in each room and practice smart energy management by controlling where heating and cooling is switched on. VRV offers user-friendly control options for maximum efficiency and versatility, or you can integrate climate control within an entire building management system.

Outdoor units - integrated heat pump solutions
Daikin renewable energy heat pumps offer a totally integrated approach to climate control:
- Solutions available for every climate from -25°C to +52°C
- Heat recovery maximises efficiency for reduced running costs and CO2 emissions
- Phased installation possible, ideal for refurbishment
- Flexible installation solutions for every building
VRV delivers up to 15% energy savings, compared with water based chiller or boiler systems.
Indoor units
Daikin offers a wide range of indoor units, stylishly designed to suit rooms of any size and shape, all with extremely quiet operation:
- Maximise usable wall space with ceiling cassettes
- For rooms without false ceilings, ceiling suspended or wall mounted units are ideal
- Wall mounted and floor standing units offer stylish, slim-line designs
- Concealed ceiling units are almost invisible and integrate easily in any type of décor
- Roundflow auto-cleaning cassettes provides the most even air flow distribution for optimal comfort, while being 50% more efficient compared with standard cassette units
Hot water
A Daikin VRV system can be combined with renewable energy solution to produce hot water:
- Free hot water production is possible thanks to heat recovery
- Solar panels can produce up to 70% of the energy for hot water production over the year
- Ideal for hot water provision for bathrooms, kitchens, under floor heating and radiators
- Water flow temperature of up to 80°C possible
Producing hot water with a VRV heat pump delivers up to 17% energy savings compared with a gas boiler.
Air curtains for entrances
Daikin VRV’s integrated heat recovery capability provides low cost heating for air curtains at entrances, ideal for buildings where doors often remain open:
- Highly efficient solution to doorway climate separation
- Free heating possible for air curtains at entrances
- Year round energy efficiency and comfort, even on the most demanding days
Air curtains using recovered heat from the VRV system delivers up to 72% energy savings compared with an electric air curtain.
Ventilation
Ventilation can be integrated within a VRV system to create fresh air provision for a high quality indoor environment:
- Heat reclaimed from indoor air can be used to heat incoming fresh air, reducing the load on the system
- Free cooling possible
- Optimum control of humidity
Ventilation using recovered heat from the VRV system delivers up to 40% energy savings, by reducing cooling and heating requirements.
User friendly controls
Full control of the VRV system ensures maximum efficiency through zone by zone control:
- Precise control of system - from individual zones to the management of multiple buildings
- User friendly touch screens
- Remote control and monitoring via the internet
VRV innovation
Daikin invented the variable refrigerant volume concept some 30 years ago and we are still the leading advocates of this innovative approach to integrated climate control, which can offer huge energy savings.
Continuous innovation through successive generations of VRV products means that VRV now offers a range of heat recovery, heat pump, cooling or heating only options, geothermal versions, replacement solutions for systems still operating on R-22 refrigerant and a VRV system running on CO2 refrigerant. Daikin has the widest range of VRV solutions available to suit your exact needs.
Geothermal VRV
Highly efficient, geothermal water-cooled applications use ground water as a renewable energy source, offering superior energy efficiency.
Heat Recovery VRV
VRV heat recovery optimises individual comfort within different areas of a building, while maximising energy efficiency by preventing energy waste.
