Offers a wide variety of new functions that benefit everyone involved
First Launched in Japan in 1982, the Daikin VRV system has been embraced by world markets for almost 40 years. Daikin proudly introduces the advanced VRV system. We provide higher benefits to various users related to air conditioning systems, for example, building owners, consultants, installers and even building management.
- InformationAdopt a new casing to realise a single module of up to 24 class
- Achieved significant energy savings with improved technology
- Defrost functions improved comfort by extending the heating operation time
- Design flexibility is further improved by simultaneous extension of height difference and equivalent length.
- Sealed electrical component box (IP55) blocks the ingress of debris or water, that leads to unexpected failures.
- A new electrical component service window on the front panel allows easy access to the main board without removing the front panel.
- Equipped with various new functions, the new model shows a significant improvement in total performance.
Top sustainability
- Reduced CO2 equivalent thanks to the use of R-32 refrigerant
• R-32 Global Warming Potential (GWP) is 68% lower than R-410A
• 10% less refrigerant charge
- Single component refrigerant, easy to re-use and recycle
- Top sustainability over the entire lifecycle, thanks to market leading real-life seasonal efficiency
Industry-leading serviceability and handling
- Low-height single fan range

Connectable indoor units
Lifecycle Cost & Comfort
Energy Saving Technology
Further improvement of energy saving by high efficiency compressor and VRT Smart II control.
Achieves high TCSPF/HSPF, that reduces running cost.
Comfort
Defrost operation before the equipment is shut down speeds up the increase of discharge air temperature of the next heating operation.•
If defrost operation time is short, the system will optimise defrost conditions, extending the heating operation time.
Efficient Space Utilisation
When construct a large-scale air conditioning system on a single refrigerant system, space for air conditioning is drastically reduced.•
Even with a 20-storey building all of the outdoor units can be installed on the rooftop.
Flexible Design & Engineering Supports
Long Refrigerant Piping
Equivalent length extension max. 190 m
Height difference extension max. 110 m (20 m longer than conventional models)
By applying for both extensions at the same time, supports a wide range of applications.
Engineering Support Software
Strongly supports for facility design, offering model selection assistance, energy saving and IEQ simulations, drawing support, etc.
Varied Lineup of Indoor Units
With various types of indoor units available, comfortable airflow is ensured in every space.
Easy Installation
Slimmer Main Piping
For gas pipe of up to 20 class, the main piping diameter size can be reduced from standard size.It enables lowering installation cost.
Electrical Component Service Window
Easy access to the main PCB without removing the front panel.
Quick field setting and trial operation.
Process visualization (Test run only)
A progress rate (0% to 99%) is indicated on the PC board for Easy arrangement for on-site work.
The REFNET piping system and DIII-NET system simplify refrigerant piping and control wiring installation.
Reliability & Comfort
IP55 Sealed Component Box
Sealed electrical component box (IP55) blocks the ingress of debris or water, that leads to unexpected failures.
Refrigerant Piping Cooling System
Refrigerant cooling circuit enables operation in high outdoor temperatures.
Energy Savings
High effieciency compressor
Improvement of the discharge port
By improving the shape of the refrigerant discharge port, the pressure increase near the discharge port of the gas refrigerant after compression is suppressed and the compression loss is reduced.
Would you like me to refine this into a technical datasheet entry, a customer-facing benefit statement, or a marketing headline that emphasizes efficiency gains?
Double Backup Operation Functions
Unit backup & Compressor backup ensure continuous operation.
Benefits of System Replacement
Enables Increased Capacity
VRV IV Q series for replacement use enables the system capacity to be increased without changing the refrigerant piping. For example, it is possible to install a 16 class VRV IV Q series using the refrigerant piping of an 10 class R-22 system.
New Technology that allows use of existing piping
Energy saving
Higher Energy Efficiency Ratio (EER)
VRV IV Q series delivers highly efficient performance, contributing to high energy savings.
- Cooling operation conditions:
Indoor temp. of 27° CDB, 19° CWB, and outdoor temp. of 35° CDB."**
