New Technology Beats Dust

Revolutionary dust-beating technology from Daikin UK adds a fresh dimension to air conditioned comfort for hotel guests – and boosts the efficiency and reliability of VRV systems.

Following the success of the self-cleaning panel option for its round flow cassettes, Daikin has introduced an automated filter cleaning system for its medium static pressure FXDQ-type slim ducted fan coil units. Typically found in hotel bedrooms, but also popular in other applications where a concealed unit is required in a ceiling void of just 240mm.

The system is also available for FDXM-F-type units, a similar design for use with R32 multi-split systems.

The new cleaning system is designed to meet the expectations of hoteliers and their guests, avoiding the basic problem of dust accumulation, which necessitates frequent servicing of filters.

Without servicing, system performance can be impaired, comfort levels are reduced and operating costs are increased. Dust build-up can also lead to dirty marks around grilles.

In tests comparing automatic weekly filter cleaning against manual cleaning at three-month intervals, the automated system delivered efficiency gains of up to 20%.

The system has a unit programmed to sweep across the width of the filter at predefined intervals. Dust is conveyed to a dust box, where it can be removed via a suction port by a domestic vacuum cleaner.

Timing and frequency of filter cleaning can be set with a Daikin remote controller, or centrally with a Daikin i-Touch Controller, i-Tab Controller or i-Touch Manager. BMS interfaces for BACnet, LonWorks and Modbus are also available.

New slim ducted units are directly compatible with the new cleaning technology, and older units can be upgraded.

Water Cooled VRV IV W+

Amid growing market acceptance for water cooled VRV systems, Daikin UK is doubling its range with the introduction of 12hp and 14hp condensers to complement the existing 8hp and 10hp systems. The new condensers have all the features of the existing range, plus technical advances.

Water cooled VRV is ideal for applications where plant space is restricted by practical constraints or planning considerations as well as where geothermal heat sources can be utilised in low-carbon projects.

Daikin’s new water cooled VRV systems are designed to lead the market by achieving the highest level of efficiency.

VRV IV W+ systems come with variable water flow control as standard which can reduce water pump energy use dramatically.

A valve controlled by compressor speed opens wider to allow more water to flow through the system when additional capacity is required. However, when less is required, the valve gap narrows and power input to the water pump is reduced, saving money and reducing carbon emissions.

With the further advantage of its two-stage heat recovery capabilities – between indoor units and via the water loop – Daikin VRV IV W+ now also provides reliable hot water generation via the same LT and HT hydroboxes used with air cooled systems. This opens new possibilities for water cooled systems to provide a complete solution for temperature control needs in a building.

Whether installed in basements, plant rooms or riser cupboards, Daikin VRV IV W+ systems are designed for a minimal space requirement. With a footprint of just 0.429m2 they have the market’s smallest footprint per kW of output.

And where there is clear height of 3.2m, they can be stacked to produce up to 120kW per stack. This combination of compact dimensions and high performance allows developers to maximise lettable space.
