The thermal energy process enables Bashas’ to reduce the amount of time it has to run the facility’s conventional electrical refrigeration system during more expensive peak load hours — that’s between 2 p.m. and 7 p.m. each day when customer demand is highest for SRP and when the cost of power is up to three times as high as during nonpeak hours.Bashas can now run the electrical refrigeration system mostly during nighttime hours when costs are lower.“The less expensive and more efficient nighttime refrigeration run time refreezes the phase change materials, and those ice packs are then able to maintain stable temperatures in the facility to keep the ice cream adequately frozen during much of the daytime peak load period,” says SRP research engineer Alejandra Mendez.“We have been able to shed about five hours of running conventional refrigeration off the peak load time and shift it to the nighttime operations,” Mendez says.Such peak load shifting, especially in large industrial facilities that operate day and night, also saves SRP money in the long run.ASU engineers (left to right) Robert Wang and Kristen Parrish discuss energy systems operations inside the 10,400-square-foot ice cream freezer with Salt River Project research engineer Alejandra Mendez and senior engineer Catherine O’Brien.

Above: An Arizona State University engineering team is working with the Salt River Project utility, the Viking Cold Solutions company and the Bashas’ Family of Stores grocery chain on a thermal energy system to reduce the costs and the amount of electrical power needed to keep large food storage facilities refrigerated at sub-zero temperatures.

It is a food preservation system, with over 75 years of innovative thinking behind it. Neda Askari, who is pursuing a doctoral degree in civil, environmental and sustainable engineering — with a focus on the latter field — and Prathamesh Vartak, a materials science and engineering doctoral student, are helping to measure the efficiency of the thermal energy storage system and to model the energy and cost impacts of such systems.Beyond the value the endeavor may yield for Bashas’ and SRP, Parrish and Wang are hoping it leads to blueprints for successfully replicating the system in a variety of other large-scale industrial freezer operations.The project extends an almost 30-year partnership between SRP and ASU.“We communicate about the needs we have and then once a year our staff meets with ASU people to brainstorm new projects,” says SRP engineer Mendez. “No electricity is needed to drive the melting process of the phase change material.”The benefit SRP and Bashas’ hope to reap from the project is not simply energy efficiency but also significant energy costs savings.

So the cold weather IP security camera function even in a much colder environment… “With a non-mechanical, passive energy storage technology you won’t need to make expensive upgrades to an existing refrigeration system.”The ultimate goal of the project is to determine if users’ electric bills can be adequately reduced to offset much of the installation costs of the thermal energy storage systems.“If that’s the case,” says SRP research and development manager Hunter, “we hope to develop a customizable thermal energy storage system incentive plan to offer to customers who will implement these measures.”ASU engineers Parrish and Wang hope to see positive signs for the system’s future capabilities once there is complete data on its performance over this year’s hot and humid summer.The researchers expect to have sufficient data to present the project’s results to the American Society of Heating, Refrigerating and Air-Conditioning Engineers at the organization’s conference in January.The phase change material has already allowed Bashas’ to run compressors less often during the hottest hours of the day — the peak load time when electrical power is most expensive — resulting in lower operating costs, Parrish says. “Then we match the professors with SRP’s people to tackle specific challenges.”There are currently more than 45 collaborative research projects involving more than 30 ASU faculty members — most of them within the Fulton Schools.Says SRP’s Hunter, “It’s great to have a place nearby where we can access all that expertise.”Joe Kullman is a science writer for the Ira A.
