Benefits of system replacement
Quick, Quality and Economical
Simple use of existing refrigerant piping.
In the past, special equipment and work was needed to clean pipes when using existing piping, but this is no longer required. A new function automatically deals with contamination inside piping during refrigerant charging, eliminating the work involved in cleaning.
Even applicable for non-DAIKIN systems!
The Daikin low-cost upgrade solution
Refrigerant charging, cleaning and test operation done with just a single switch.
The unique automatic refrigerant charge eliminates the need to calculate refrigerant volume, simplifying the installation process. Not knowing the exact piping lengths because of changes or mistakes in case you didn't do the original installation or replacing a competitor installation no longer poses a problem. Furthermore, there is no need to clean inside piping as this is handled automatically by the VRV IV Q unit.
Enables smooth replacement of air conditioning with less effect on operations and users in the building.
Work costs for pipe removal, installation and insulation account for much of the total cost. By the reuse of existing piping, 35% of cost down can be realized compared to installing new pipes.
Significantly more compact outdoor unit enables the effective use of limited space!
Compact design enables the effective use of space taken up by existing machinery
High external static pressure 78.4 Pa
Small and light, significantly reducing constraints during carry-in

An increased number of connectable indoor units in a single system
More indoor units can be connected in a single system, enabling consolidation of existing piping!
The number of connectable indoor units has been drastically increased from 30 to 64.
Enables increased capacity
System can be upgraded using existing piping
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 HP VRV IV Q series using the refrigerant piping of an 10 HP R-22 system.
For reuse of existing refrigerant piping, it is possible to use piping or branched piping capable of handling 3.3 MPa or more.
Heat insulation is necessary for liquid piping and gas piping.
2 types up to 48 HP
With its enhanced lineup of 2 types and Standard and Space saving types, VRV IV Q series outdoor units offer a high capacity up to 48 HP to meet an ever wider variety of needs.
Compact & Light Weight Design
New Space Saving type with refined design
As a leading global innovator, Daikin advanced from the conventional 2 module combination to a single module for 18 and 20 HP models. This allows the installation area to reduce by 33% as compared to the previous models.
Higher Coefficient of Performance (COP)
COP at 100% operation load
VRV IV Q series delivers highly efficient performance, contributing to high energy savings.
COP for 10 HP
Improved efficiency during long operation under low load
VRT-Variable Refrigerant Temperature
State-of-the-art energy saving technology for VRV system
Customise your VRV system for optimal annual efficiency
The new VRV IV Q series now features VRT technology. VRT automatically adjusts refrigerant temperature to individual building and climate requirement, thus further improving annual energy efficiency and maintaining comfort. With this excellent technology, running costs are reduced.
How is energy reduced?
During cooling, the refrigerant evaporating temperature (Te) is raised to minimise the difference with the condensing temperature. Compressors work less, and this reduces power consumption.
Typical changes in evaporating temperature and COP depending on changing indoor load
New system, saving more energy
Basic mode is selected to maintain optimal comfort.
VRT is selected to save energy and prevent excessive cooling.
VRT offers quicker cool down to shorten uncomfortable pull down time.
Recommended for use in these situations
- Cooling only regions having differences in daily temperature.
- VRT is particularly effective at night when temperatures are low.

Various advanced control main PC board
SMT* mackaging technology
- SMT packaging technology adopted by the whole computer control panel improves the anti-clutter performance.
- Protects your compter boards from the adverse effect of sandy and humid weather.
Refrigerant cooling technology, ensures stability of PCB temperature
Improve reliability at high ambient temperature
It is possible to cool the inverter power module stability even at high ambient temperature.
This helps to keep air-conditioning capacity and also reduces failure rate.
Outdoor Unit Lineup
