Installtion space and cost are reduced by large-capacity casing for max 24 class.
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.

Now up to 24 Class
New Design casing that realises a single module of up to 24 class
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?
Optimising the back pressure control / New oil control function
In addition to the conventional intermediate pressure adjustment port, the pressing pressure of the orbiting scroll during operation has been optimised, and the newly adopted oil control mechanism has reduced gas leakage and mechanical loss.
Adoption of a high-performance concentrated motor
By adopting it, the coil circumference is greatly reduced, which makes the coil denser and thicker, and the electrical resistance of the coil is dramatically reduced to improve motor efficiency. Furthermore, the motor is light-weighted and downsized.
Design Flexibility
Simultaneous extension of height difference and equivalent length
Design flexibility is further improved by simultaneous extension of height difference, improved from 90 m to 110 m, and equivalent length (up to 190 m).
Height difference extension - Max. 110 m
For height differences exceeding 50 m with the outdoor unit above the indoor unit and 40 m with the outdoor unit below, the main piping liquid piping size must be increased.
Equivalent length extension - Max. 190 m
When the equivalent piping length from outdoor unit to indoor unit is 90 m or more, be sure to increase the main piping liquid piping size.
*In addition to increasing the size of the main pipe, there are other piping restrictions regarding height difference extension and equivalent length extension. Check the Installation Manual for details.*
REFNET header downstream branching supported
Piping branch by REFNET joint is possible downstream of REFNET header. The indoor unit arrangement can be more flexible.
Long Piping Length
Long Piping length enhances design flexibility, enabling support for large buildings.
*1. No special requirements up to 40 m. The maximum actual piping length can be 90 m, depending on conditions. Various conditions and requirements have to be met to allow utilisation of 90 m piping length. Be sure to refer to the Engineering Data Book for details of these conditions and requirements.
*2. When Height differences above 50 m if the outdoor unit is above the indoor unit and 40 m if the outdoor unit is below the indoor unit, a dedicated setting on the outdoor unit is required. Refer to the Engineering Data Book and contact your local dealer for more information.
*3. When Height differences are 15 m or more, maximum actual piping length must be 120 m.
*4. In the case where the equivalent piping length from outdoor unit to indoor unit ≥ 90 m, make sure to up size the liquid pipe of the main pipe. Do not up size the high/low pressure gas pipe and the suction gas pipe.
Connection Ratio
Connection Capacity at maximum is 200%
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.
*1 For the FXF(S)(T)Q25 models, maximum connection ratio is 130 % for the entire range of outdoor units.
Note: If the operational capacity of indoor units is more than 130%, low airflow operation is enforced in all the indoor units.
Benefits of System Replacement
Automatic
Refrigerant charging, cleaning, and test operation can be done with a single switch.
The automatic refrigerant charge function automates the charging of the proper refrigerant amount and the closing of shut-off valves by pressing a switch after pre-charging.
Cleaning inside piping is unnecessary because it is handled automatically by the VRV IV Q unit.
*Note: There are conditions (ambient temperature, connection ratio) under which the automatic refrigerant charge can be used. The refrigerant amount automatically charged may differ from calculated values but does not affect performance or quality.*
Time Saving
Enables smooth replacement of air conditioning with less effect on operations and users in the building.
Cost Saving
By the reuse of existing piping, 35% of the 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.
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.
High External Static Pressure 78.4 Pa
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.
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.
VRT Control for optimal annual efficiency
VRT automatically adjusts refrigerant temperature to individual building and climate requirement, thus further improving annual energy efficiency and maintaining comfort.
New Technology that allows use of existing piping
New tested contamination collection method: Collects contamination from existing piping, eliminating compressors and electric valve malfunction.
Reliable and Stable Technology
High reliability at high ambient temperatures
Using refrigerant to cool the inverter power module helps minimise the size of the electronic components, and this results in reduction of airflow resistance and high efficiency of the heat exchanger.
