VRVEuropean designOver the years, the Daikin VRV systems have been designed with European taste in mind, optimised for the European climate and manufactured in Europe for Europe. As the market leaders, Daikin understands the European market.
Setting the standard Daikins continuous development of the VRV air conditioning system means it has always been and will always continue as the benchmark standard for European air conditioning systems. The VRV VI is currently setting challenging new standards for seasonal efficiency, optimised climate control and ease of installation.
A total solutionThe Daikin VRV Total Solution service provides a single point of contact for the design and maintenance of each integrated climate control system. By making a careful choice from our modularised units the right mix of equipment and technology can be selected to ensure the optimal balance of temperature, humidity and air freshness for the perfect comfort zone while delivering maximum energy efficiency, minimum operating costs and reduced CO2 emissions.
The originalThe VRV air conditioning system is the worlds rst individual air conditioning system with variable refrigerant ow control and was commercialized by Daikin in 1982. VRV is the trademark of Daikin Industries Ltd., which is derived from the technology we call Variable Refrigerant Volume.

Why choose VRV?Low operating costsOur latest equipment is designed to optimise performance of the total system, automatically, every minute of the day. This includes highly eciency outdoor units, indoor units with intelligent sensors, heat recovery technology, smart energy management controls and much more.
According to the Franklin + Andrews, one of the worlds leading construction economists, running costs for VRV heat recovery systems compare highly favourably with a 2 or 4 pipe fan coil system. Running costs per m2 Gross Floor Area of a fan coil system can be 40 to 72% higher compared to a VRV heat recovery system.
A VRV system is more space ecient than a chiller too, because it requires much less plant space. For example, Franklin + Andrews estimates that VRV system could take up 29% less plant space than a chiller system. And in a highly competitive market place, oering the most exible and ecient use of oce space can be a real deal breaker.
Personal comfort for tenantsWhen viewed from the perspective of the occupants of a building, it is the comfort level provided by the climate control system that is the most important and so the temperature has to be right, there has to be enough fresh air with the correct humidity level and the sound level has to be minimized.
Our VRV system addresses all of these requirements and provides individual control where possible. Sound levels of our indoor units can be as low as 19 dBA. Futhermore VRV IV continues to provide heating, even when in defrost mode, providing the answer to any perceived disadvatages of using a heat pump for monovalent heating. While in cooling mode it eliminates any cold draught thanks to higher outblow temperatures.
Meeting tomorrows legislation todayVRV also meets the requirements of the Energyrelated Performance Directive and has been designed for seasonal eciency with future legislative requirements in mind.
Furthermore the VRV provides greater exibility to meet current and future client requirements, because the system can be designed, built and commissioned zone by zone and tailored to the needs of each building tenant throughout a phased refurbishment programme.

Precise zone control to suit building occupancyEach oor even each room can be individually controlled to maximise energy eciency and prevent energy waste. This versatility makes VRV ideal for buildings with multiple tenants, which may have vacant areas and variable periods of high and low usage.
Modular approach gives greater flexibilityVRVs modular approach provides greater exibility to balance heat loads in dierent parts of the building. VRV also oers extended piping lengths so the system can be designed exibly to suit buildings of many dierent sizes and shapes.
Reliability you can depend onOf course, ensuring lower running costs depends on system reliability and eciency over its entire lifetime. So its reassuring to know that Daikin has an unparalleled reputation for quality, reliability and after sales service.
The VRV total solution
Many buildings today typically operate quite separate systems for heating, cooling, refrigeration and hot water. As a result, a huge amount of energy is wasted. To provide a much more efficient alternative, VRV technology has been developed into a total solution managing up to 50% of a buildings energy consumption giving large potential to cost saving.

Heat pumps are known for their high energy efficiency in heating, but they accumulate ice during heating operation and this must be melted periodically using a defrost function that reverses the refrigeration cycle. This causes a temporary temperature drop and reduced comfort levels inside the building.
Defrosting can take over 10 minutes (depending on the size of the system) and occurs most frequently between -7 and +7C when there is most humidity in the air, which freezes to the coil, and this has a significant impact on the perceived indoor comfort levels.
The VRV IV has changed the heating pardigm by providing heat even during defrost operation thus eliminating the temperature drop inside and providing comfort at all times.

2. Continuous heating during defrost
A unique heat-accumulating element, based upon phase change materials, provides the energy to defrost the outdoor unit. The energy needed for defrosting is stored in the element during normal heating operation.
How does it work?Heat accumulating element
Alternate defrost
The outdoor unit coil is defrosted
with the energy stored in the heat accumulating element
while indoors a comfortable temperature is maintained.
VRV IV continues to provide heating even when in defrost mode, providing an answer to any perceived disadvantages of specifying a heat pump for monovalent heating.
Indoor comfort not affected either via the unique heat accumulating element or alternate defrost The best alternative to traditional heating systems
the outdoor unit coil is defrosted
one at the time
so indoors a comfortable temperature is maintained
On all our multi model combinations only 1 outdoor coil is defrosted at a time, ensuring continuous comfort during the whole process.

Benefits for building ownersDrastically reducing your running costsA long lasting investment
Precise zone control VRV systems have low running costs because it permits each zone to be controlled individually. That is, only those rooms that require air conditioning will be heated or cooled, while the system can be shut down completely in rooms where no air conditioning is required.
Smart energy management Smart energy management tools reduce running costs by preventing energy wastage. Using the schedule function and monitoring tools you can easily detect origins of energy waste and track consumption to ensure it is according to plan. Our intelligent tools maximize efficiency at all times.
Indication of where energy saving is possible
All inverter compressors All inverter control compressors allow to control the refrigerant volume almost stepless. In this way the capacity perfectly matches the different loads in every room avoiding unnecessary energy use.
Additionally all inverter compressors also allow precise refrigerant temperature control, automatically adapting your VRV to your building and climate requirements, reducing runnig costs with 28%.

Smart Control Brings Comfort Stable room temperatureAn electronic expansion valve, using PID (Proportional Integral Differencial) control, continuously adjusts the refrigerant volume in respond to load variations of the indoor units. The VRV system thus maintains comfortable room temperatures at a virtually constant level, without the temperature variations typical of conventional ON/OFF control systems.
No more cold draughtAutomatic or manual adjustment of refrigerant temperature leads to higher outblow temperatures which avoid the cold draught coming from the indoor unit.

Multiple tenants, one outdoor unit The multi tenant function ensures that the entire VRV system does not shut down when the main power supply of an indoor is switched off. This means that the indoor units main fuse can be turned off when a part of the building is closed, is being serviced,
No structural reinforcement necessary Thanks to the vibration-free and sufficient light construction of the outdoor units, floors do not need to be reinforced, reducing the overall cost of the building when compared to a chiller.
Indoor installation The VRV optimised fan blade shape increases output and reduces pressure loss. Together with the high ESP setting (up to 78pa), it makes VRV outdoor units ideal for indoor installation using ducts.
Indoor installation leads to less piping length, lower installation costs, increased efficiency and better visual aesthetics.

More free heat Daikin 3-pipe technology needs less energy to recover heat, meaning signicant better eciency during heat recovery mode. Our system can recover the heat at low condensing temperature because it has dedicated gas, liquid and discharge pipes.
In a 2-pipe system gas and liquid travel as a mixture so the condensing temperature needs to be higher in order to separate the mixed gas and liquid refrigerant. The higher condensing temperature means more energy is used to recover heat resulting in lower eciency.

Maximum comfort at all times Thanks to the VRV BS box, all indoor units which are not switching from cooling to heating or vica versa continue to provide heating or cooling. This is because our heat recovery system does not need to equalize pressure over the entire system after a change-over.

VRV IV proven in practice:
40% more ecient
Results: up to 60% less energy consumed The results of the trial showed that the new VRV IV system consumed much less energy, particularly when cooling, compared with the VRV III system in some cases up to 60% less. When heating, savings were an average of 20%.
The Unterhachingtrial demonstrates how VRV IV heat pump technology uses a renewable energy source air - to provide a complete and environmentally sustainable solution for heating, cooling, and ventilation in commercial environments. The trial also shows that businesses can only identify and control energy wastage through careful and intelligent monitoring of climate control systems, a service which Daikin can offer.
A field trial at a German fashion chain store demonstrated how the innovative features of VRV IV have improved energy efficiency dramatically over previous models.

2 Smooth air inlet bell mouth and aero spiral fanThese features assist in significantly reducing noise. Guides are added to the bell mouth intake to reduce turbulence in the air flow generated by fan suction. The aero spiral fan features fan blades with bent blade edges, further reducing turbulence.
Conventional NewEscaping edges are sucked in by the bent blade edges, reducing overall turbulence.
Aero spiral fan blade tips
1 Super aero grilleThe spiral shaped ribs are aligned with the direction of discharge flow in order to minimise turbulence and reduce noise.
Advanced technologies
Evaporative capacity can be raised by taking super cooling just before the electronic expansion valve
By the SCe- bridge circuit, cooling and heating attain the improvement in COP
SCe-Bridge Circuit
Evaporative-capacity has been improved by adopting the SCe-Bridge Circuit circuit.
Current Evaporative-
capacity
3 e-Bridge circuit Prevents accumulation of liquid refrigerant in the condenser.
This results in more efficient use of the condenser surface under all conditions and leads in turn to better energy efficiency. Increased evaporative capacity stems from the newly developed refrigeration circuit, the SCe-bridge circuit, which adds super cooling prior to the expansion cycle. By adopting this circuit, the COPs in both coolingand heating have been drastically improved.
