Air conditioning has become the norm in most new and refurbished hotels. Today's systems keep guests cool during summer and provide cost-efficient heating during winter. Daikin heat pumps use renewable energy to do this, cutting hotel operating costs. And there's also a positive impact on indoor aesthetics.
As a leading manufacturer of heatpump systems, Daikin is at the very forefront of technological development. Far from concentrating solely on temperature control, its engineers and designers are constantly working to improve the 'total solutions' for key market sectors, such as the hotel industry, offering cooling, heating, hot water, ventilation and refrigeration with a single point of contact.
Daikin's most recent control innovation is the stylish Madoka, an intuitive touch-button controller that enables guests to adjust room temperatures for greater comfort. Its Bluetooth connection gives maintenance staff access to all other system settings, and with a choice of white, black or silver housings, Madoka fits any hotel interior design.
Another recent innovation is the auto-cleaning duct, an accessory that attaches to a Daikin ducted unit - typically in a hotel bedroom ceiling - and automatically cleans the filter. This was a key component that prompted a high-end hotel in the Channel Islands to switch to the Daikin total solution when its old systems were due for replacement.
The Pomme d'Or Hotel, in Jersey, heads the hotel and leisure portfolio of Seymour Hotels in Jersey. The long-established, 143-bedroom art deco hotel has a prime location close to the island's main business district, and overlooking the port and marina. It enjoys year-round popularity among business and holiday visitors.
David Donoghue, group maintenance manager, says, "We chose the Daikin solution for heating and cooling because it included the auto-cleaning duct on the indoor units."
The auto-cleaning duct avoids accumulation of dust on the filter, which would otherwise affect the efficiency of the unit and increase operating costs. In fact, the accessory is calculated to cut operating costs by 20%.The attachment thoroughly cleans the filter periodically and stores the dust in a dust box, which can be emptied by housekeeping staff quickly with a vacuum cleaner.
Donoghue continues, "This is the big selling point that tipped it for us. We used to spend a lot of time cleaning the filters by hand every two or three months. It was only about 30 minutes in each room, but it was disruptive and expensive. And as the engineer had to remove ceiling panels to access the filters each time, it inevitably led to decoration issues, such as damaged panels and dirty ceilings."
Donoghue concludes "The big benefits are that we get greater efficiency from the systems and we can deploy our maintenance team more resourcefully."
The Pomme d'Or Hotel's system is ultimately controlled by a Daikin Intelligent Touch Manager mini- BMS, which gives a central view of the entire system.
