Airstage

Two Fujitsu Standard Airstage roof top rated packaged models have been not too long ago installed on the roof of a 24-hour McDonald’s restaurant in Burwood, Victoria.

Pursuing Fujitsu General’s assessment of the engineering brief, the installation was managed by Metro Air (Victoria) and integrated two 66kW Airstage rooftop packaged models (with Economiser and De-Super Heater), anywAiR iO controls, and a variable refrigerant stream (VRF) method.

The restaurant was undergoing a refurbishment, which incorporated modifying the inside structure and replacing the air conditioning. The new technique was necessary to give control possibilities to minimise the restaurant’s power use, even though also furnishing usage reports that arm the franchisee with information and facts to make informed small business choices.

Whilst the inside format of the cafe was currently being modified, the roof would keep on being the very same. The new HVAC process experienced to use the present duct layout and no new penetrations could be built. ­­­

Fujitsu states its two 66kW models would supply the indoor convenience the personnel was accustomed to, with the hottest technology suited for a commercial set up of this size. Just one unit was mounted for the kitchen area region, and yet another for the dining place.

In accordance to Fujitsu, the refurbishment was component of McDonalds’s intention to slice its greenhouse fuel (GHG) emissions by 36 for every cent by 2030, whilst also committing to a web zero emissions focus on by 2050. To achieve this, strength administration techniques for lights and HVAC are being current, and more effective kitchen area devices set up across the chain’s dining establishments. The enterprise says that since its 2015 foundation calendar year, McDonalds has diminished complete emissions from its places to eat and workplaces by 8.5 per cent.

Fujitsu suggests that no matter of the outdoor temperature, a restaurant kitchen can turn into unbearable if not managed successfully.

“The Economiser solution enables high energy-saving procedure, as the out of doors air is applied for cooling or warming the inside air,” states the organization. “Based on absolutely free-cooling technology, the unit functions a few dampers intelligently managed by an electronic regulate that continuously monitors the internal and exterior air temperatures.”

The engineering transient also specified a De-Tremendous Heater be connected to the hot water program.

“The De-Tremendous Heater captures and transfers the warmth energies from the refrigeration cycle to the hot-drinking water loop by means of a warmth exchanger, relatively than rejecting the heat energies by way of the de-tremendous heating and condensation system on the condenser aspect into the atmosphere,” suggests Fujitsu. “Incorporating a De-Super Heater in the project would supply the cafe with an supplemental sensible ability preserving answer.”

For remote manage capacity, Fujitsu Common mounted anywAiR iO with wireless sensors. This allows the franchisee keep track of the wattage remaining eaten, control the procedure procedure, and remotely change the set temperature. The technique also lets the franchisee join with and handle other restaurant areas from a single dashboard, in the business or by using cellular cell phone.

The VRF process was installed for a lesser area that experienced previously been an out of doors area and was currently being enclosed as an all-temperature occasion home.

“Metro Air has managed many McDonald’s refurbishment projects to update the HVAC units,” says Metro Air Running Director Tony Gormley. “We have used Fujitsu Typical VRF ducted in some restaurants on the other hand, the Burwood job was the very first time we had labored with the Fujitsu Basic used solutions. The rooftop packaged units ended up basic to put in, and Metro Air has happily mounted Fujitsu Common used products and solutions in commercial and large-conclusion domestic tasks where by acceptable.”
