Benefits
Benefits of system replacement
Quick, Quality and Economical
Reuse 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
Automatic
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.
Time saving
Cost saving
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.
Design Flexibility
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
System flexibility
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.
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.
Energy Saving
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
Features
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

Recommended for use in these situations
- Cooling only regions having differences in daily temperature.
- VRT is particularly effective at night when temperatures are low.
Advanced Technologies Achieve
New technology that enables use of existing piping
New tested contamination collection meth
A new method collects contamination from existing piping, eliminating compressors and electric valves malfunction.
Acid
An acid neutraliser agent is added to disable acids (chlorine ions), which cause corrosion.
Impurities
A generously sized filter is provided inside the refrigerant circuit which traps impurities.
Iron powder
A magnet is installed inside the accumulator where liquid refrigerant accumulates. The magnet attracts iron powder to keep the system clean.
