As utilities are a major expense for restaurant operations, McDonald’s Australia has been exploring energy efficiency improvement opportunities in its restaurants. HVAC systems represent one of the largest opportunities in this area because they account for approximately 25 percent of a McDonald’s Australia restaurant’s consumption.
McDonald’s Australia optimized the energy efficiency of its refrigeration equipment and HVAC systems by installing the product IceCOLD®. IceCOLD® improves the efficiency of the heat exchanges by removing the naturally occurring oil fouling from the tubing and coil walls. As a result, cooler air flow is generated from the system. The shortest payback is achieved on equipment more than three years old.
The initial results have indicated a 20 percent energy savings on HVAC and refrigeration. Currently seven restaurants across the country are participating in the trial. McDonald’s Australia is evaluating the payback and, depending on the results, will make it available to all restaurants.
