Daikin proudly introduces the VRV III series, which is well-suited to large-sized buildings. This air conditioning system provides outdoor units that extend air conditioning capacity up to 54 HP. It also incorporates numerous outstanding features, such as a wide range of outdoor and indoor units, long actual and total piping length, and high external static pressure. The VRV III series provides the power and versatility you need for flexible design and easy installation in large-sized buildings. The Heat Recovery Series also enables simultaneous cooling and heating, meeting the various needs for temperature control

Outdoor unitsOffering a high capacity of up to 54 HP

The system has a top output of 54 HP, meeting the needs of large-sized buildings. Daikin has also introduced a single 18 HP model that may serve as the main unit in combination solutions.

2 HP increments

By providing a range of horse power levels in 2 HP increments*, Daikin responds flexibly to customer needs.

Selectable from two types of combinations

The outdoor units are selectable from two types of combinations, normal type (space saving type) or High-COP type (Energy saving type) depending your needs.

1. Newly improved fans and grilles

A higher external static pressure has been achieved-from 58.8 Pa to 78.4 Pa-thanks to reduced internal pressure loss, use of the new fans and the new grilles.

New aero spiral fan and aero asymmetrical fan

The area of these new fan blades has been increased and optimised for each casing. This greatly reduces pressure loss, resulting in a higher external static pressure.

New aero asymmetrical fan

The three-bladed fan on the 10 HP unit, with a diameter of 700 mm, has been redesigned to include four blades and now has a diameter of 680 mm. Blade area has been increased by 25%.

New aero spiral fan (Powerful Dual DC fan)

In the 14 and 16 HP unit, a single fan with a diameter of 700 mm has been split into two fans with diameters of 540 mm each. Blade area has been increased by 20% to increase airflow.

Aero smooth grille 

The three-dimensional, integrated, soft woven steel grilles are covered with a plastic coating that protects them from rotating elements and the possibility of fire damage.

2. Heat exchanger

The new heat exchanger contributes to a higher COP because of an increase from 7% to 10% of the effective length as well as an optimised e-Pass heat exchanger.

3. Improving the high efficiency compressor to achieve a higher COP and larger capacityReluctance DC scroll compressor

Daikin's unique scroll compressor minimises heat loss, and is driven by a high efficiency motor to achieve significant Energy savings.

4,Heat transfer circuit

By performing sub cooling before the expansion process, the volume of refrigerant that needs to be circulated to the indoor units can be reduced without lowering the evaporation temperature. This permits the use of narrower piping.

5. Compact aero box

Realises a compact casing by stacking the Inverter and control PCBs plus optimising the internal design to suit airflow speed. This achieves lower noise and reduces the power required by the large-diameter fanned outdoor unit

6. Smooth sine wave DC Inverter

By adoption of the Sine Wave, which smoothes the rotation of the motor, operation efficiency is improved sharply.

7. DC fan motorAcross entire range of models (from 5 to 54 HP).Efficiency improvement by up to 40% especially at low speed.
