Reusing existing piping for speedy replacement to an advanced energy-saving air conditioning
Upgrading air conditioning systems in the past used to require replacement of refrigerant piping in buildings, leading to major construction and costs exceeding those of the original installation.
To save time and cost, Daikin developed the VRV IV Q Series as a model specializing in system replacement, This revolutionary system reuses existing piping and enables quick and high quality replacement to the latest energy-saving air conditioning system without renovation work for new piping.
Reusing existing refrigerant piping minimizes:

Benefits of System Replacement
Engineered for Flexibility
First launched in Japan in 1982, the Daikin VRV system has been embraced by world markets for over 30 years. Now, Daikin proudly introduces the new VRV IV S series-the ideal air conditioning system for homes, shops and offices.
VRV indoor units combine with residential indoor units, all in one system.
Compact & lightweight design
The new design has been optimised for the VRV IV S series, with the height of 4 HP to 5 HP models reduced to only 990 mm. This design gives the building a sleek look externally and provides the occupants with a clear, unobstructed view of the scenery. The VRV IV S series is now slim and compact, with outdoor units that require minimal installation space.
To suit a variety of room sizes, VRV IV S series expands our range to include 8 HP and 9 HP
Wide variety of indoor units
Higher Coefficient of Performance (COP)
VRV IV S series provides greater energy saving as compared to VRV III S series, especially for 6 HP.
Nighttime quiet operation function
Operation sound level selectable from 3 steps for the night mode
Mode 1. Automatic mode
Set on the outdoor PCB. Time of maximum temperature is memorised. The low operating mode will initiate 8 hours*1 after the peak temperature in the daytime, and normal operation will resume 10 hours*2 after that. The operation sound level for the night mode can be selected from 49 dB(A) (Step 1), 46 dB(A) (Step 2) and 43 dB(A) (Step 3).*3
Mode 2. Manual mode
Starting time and ending time can be input. (An external control adaptor for outdoor unit, DTA104A53/61/62, and a locally obtained timer are necessary.)
Mode 3. Combined mode
Combinations of modes 1 and 2 can be used depending on your needs.
*1. Initial setting. Can be selected from 6, 8 and 10 hours.
*2. Initial setting. Can be selected from 8, 9 and 10 hours.
*3. In case of 4 HP outdoor unit during cooling operation
Design flexibility and simplified installation
Connectable up to 14 indoor units
As many as 14 indoor units can be connected to a single outdoor unit, making the VRV IV S series a remarkably versatile system.
Note: Total capacity index of connectable indoor units must be 50-130% of the capacity index of the outdoor unit. Refer to page 46 for the maximum number of connectable indoor unit.
Automatic test operation
Simply press the test operation button and the unit performs an automatic system check, including wiring, stop valves, piping, and refrigerant charging amount. The results are returned automatically after the check finishes.
Simple wiring and piping connection
Unique piping and wiring systems make it possible to install a VRV IV S series quickly and easily
Long piping design possible
Long piping length offers flexibility in the choice of installation positions, and simplifies system planning.

When a mixed combination of VRV and residential indoor units is connected or when only residential indoor units are connected
Indoor Unit Lineup
Enhanced range of choices
A mixed combination of VRV indoor units and residential indoor units can be included into one system, opening the door to stylish and quiet indoor units.
Daikin offers a wide range of indoor units includes both VRV and residential models responding to variety of needs of our customers that require air-conditioning solutions.
VRV AHU Introduction
Daikin released 2 series of VRV AHU,standard series model AHUR-DBV/CBV and outdoor air series model AHUR-DBL/CBL. It is a DX AHU that is specially designed to operate with VRV IV outdoor unit. This enabled the users to reduce maintenance costs and enjoy more space savings.
Daikin VRV AHU improves the indoor air quality caused by haze, pollutants, etc with options of pre-fillers and primary filters.
This is the only total AHU solutions provided and manufactured completely by Daikin.
What is VRV?
Daikin VRV system is a multi-split tye air conditioner for commercial buildings that uses variable refrigerant flow control invented by Daikin.
It allows one touch selection control using intelligent Touch Manager and includes options to link with BACnet to enhance the Building Management System (BMS).
VRV AHU Application
From small to large commercial spaces, Daikin offers a wide range of R-410A inverter condensing units for use in conjunction with Air Handling Units(AHU) from 6 HP to 120 HP.
AHU provides large air volumes and high ESP (External Static Pressure) enabling the use of extensive ductworks. The refrigerant flows through the copper pipes using R-410A and operates like a large VRV fan coil unit.
Daikin AHU represents the ideal solution for large storage places, atrium, lobby, banquet halls, showrooms, exhibition halls, shopping malls, etc.
It also has the options to customize the specifications such as the filtration type, direction of air in-take and discharge, servie access door and blower type(backward or forward curves and plug fan).
Features of VRV AHU
- Communication protocol using DHII-Net to communicate with all existing Daikin communication devices. (options to connect directly to BACnet BMS
Benefits of using VRV AHU
- VYV AHU are manufactured by Daikin factory.
- No additional system such as cooling tower, chiller, and long water piping system
- Flexible design of the ducting system
- Integrating an AHU into the total building climate system enables both design and installation procedures to be based on a single common technology. This simplifies project follow-up, installation, commissioning and maintenance since only one party is involved.

VRV User Benefits
For property OWNERS
First launched in 1982, the Daikin VRV system has been providing comfort and reliability to building owners and their tenants for over 35 years. Leveraging the latest in energy- saving technology, Daikin has further improved energy savings while reducing space requirements. This added value is one reason why Daikin is the right choice for building owners.
Energy saving & comfortable environment
Efficient space utilisation
Daikin VRV system can be used to develop a large-scale air conditioning system on a single refrigerant system, thus reducing the space required for air conditioning equipment. Because the difference in height between the indoor and the outdoor unit can be as large as 90 m, even with a 20-storey building all of the outdoor units can be placed on the rooftop for more efficient utilisation of space.
Double backup operation
Residential indoor units
*For indoor units connectability, please refer to the indoor unit product lineups.
For CONSULTANT and DESIGN OFFICES
Varied lineup of models
Long piping provides more flexible system design
Compatible with engineering software
Automatic refrigerant charge function
Lightweight and compact large-capacity single units
Simple piping, easy wiring
Greater energy savings during low-load operation
Efficiency During Actual Operation
Optimum utilisation of VRT Smart Control and VRT Control
Effectiveness can be demonstrated for VRT Smart Control and VRT Control when all the indoor units operate under low load conditions in a similar manner. Low load conditions are the time when room temperature approaches set temperature. For this reason, please note the following to maximise energy .
When selecting indoor units
Indoor units are installed in a system so that they operate largely under the same conditions.
Energy efficiency decreases for the installation patterns shown below.
