Realising compact technology with performance

Refined Design Meets Advanced Technologies

As a leading global innovator, Daikin advanced from the conventional 2 module combination to a single module for 20 HP model. This allows the installation area to reduce by 43% as compared to the previous VRV 20 HP model.

With this unbridled passion for high quality and advanced technology solutions, the new 20 HP is designed with the following considerations:

Design considerations

Increase surface area of heat exchanger for better performance Easy maintenance

Sufficient cooling for electrical componentEliminate suction resistance issue to enhance air flow volume.

VRV 20 HP 20 HP

43%Decrease

Installation space

Increase surface area of heat exchanger

The unique 4-sided all round heat exchanger ensure sufficient surface area for the heat exchanger as oppose to conventional 3-sided heat exchanger. This improves the heat exchanger performance without increasing the footprint.

Easy maintenance

In previous VRV design, the electrical component is usually situated on the front surface which requires the whole electrical component to be removed before maintenance can be carried out.

With the new design, the electrical component is strategically located on the top which ease the maintenance process.

Moreover, the heat exchanger on the front side can be extended to take up the previous space used for the electrical component and improve its performance.

Electrical componentElectrical component

Sufficient cooling for electrical component

The new 20 HP model is designed with the electrical box strategically located between a region of positive and negative pressure. This design allows a larger air flow from negative pressure to positive pressure due to the higher pressure difference.

The small holes created in the electric box are now close to the fan blower inlet, thus a significant pressure difference can still be achieved unlike that of VRV .

Eliminate suction resistance issue

Without affecting the fan volume, the electric component is re-designed to the top and free up the dead space that existed in previous VRV models. This eliminates the problem of suction resistance.

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.

State-of-the-art energy saving technology for VRV system

Customise your VRV system for optimal annual efficiency

The new VRV IV system 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.
