Daikin introduces 'unique' VRV IV heat pump for indoor installation

Daikin Europe has launched a new VRV solution for banks, retail and other light commercial businesses.

According to Daikin, the first VRV IV outdoor unit for indoor use, the VRV IV i-series, has been developed to meet the specific demands of city and urban locations where space is limited and customers want an invisible air conditioning solution.

The company says its unique split concept with a separate compressor and heat exchanger allows the VRV IV i-series to be installed discretely indoors with the heat exchanger unit to be placed close to the indoor compressor unit, showing only the grilles from the outside.

For maximum concealment, grille units can be hidden behind façade features such as pediments, logo or even incorporated into the building design.

Indoor installation can offer a far more economical solution than conventional outdoor units, which may require expensive acoustic treatment for installation in densely populated areas.

The two-part design and easy system handling reduces the need for plant lifting into place, making the process both quicker and more cost-effective, enabling new premises to be fast-tracked.

Together with a shorter pipe-run requirement, the new system ensures installation costs are kept to a minimum and cause no disruption to neighbouring buildings.

In addition, a rotating switch box in the compressor unit can be tilted giving full and easy access to all parts from the front of the unit for easy servicing.

The two part design of the outdoor unit for the new VRV IV i-series offers unrivalled flexibility in configuration and installation.

The lightweight and extremely compact compressor unit uses only 600x550mm of floor-space and weighs just 80 kg.

With a very low operating sound of 47dBA, it is designed to fit unobtrusively into small spaces such as a back office, technical areas, storage rooms or kitchen cupboards.

The second part, of the unit, the compact heat exchanger, which is only 400mm high weighing 90 kg, allows it to be concealed in false ceiling spaces. This conceals the entire air conditioning system, avoiding take up of expensive commercial floor space.

The ESP of the VRV IV i-series inverter fan can easily be adapted to the specific duct length and layout at the required location, making both façade or ducted installation to the front or rear of the building possible.

The VRV IV i-series incorporates a patented V-shaped heat exchanger which delivers the same high efficiency as a mini VRV outdoor unit.

In addition, the super-efficient centrifugal fans which have been found to be 85% more efficient than the sirocco fans which are the market standard today, use backward-curved blade technology to ensure an efficient air flow over the heat exchanger with minimal turbulence.

Moreover, the system has been optimised to provide a higher air flow and static pressure and provide an even better efficiency compared to a standard ducted outdoor unit.

Offering the full VRV functionality of larger units, the new units incorporate Daikin’s innovative Variable Refrigerant Temperature technology which continually adjusts the system in line with outside temperatures, eliminating cold draughts and maintaining a comfortable environment, while reducing energy costs by 28% compared to standard VRV III series.

The VRV IV i-series offers a total air conditioning solution for commercial buildings, when combined with up to ten VRV indoor units, air handling ventilation units and/or an air curtain.
