International grocery chain achieves greater temperature stability with thermal energy storage system
A large international grocery chain invited Viking Cold Solutions, Inc., Houston, Texas, to conduct a measurement and verification study of its thermal energy storage (TES) technology. The purpose of the study was to determine the effectiveness of TES in a typical grocery storage freezer environment. Viking Cold's patented TES solution was installed in the 320-square-foot main grocery walk-in freezer at the Fremont, Calif., store. The freezer was equipped with a Hussmann Protocol rack refrigeration system, Emerson E2 controls and Parasense monitoring.
