This article summarizes over a decade’s worth of key research efforts by Southern California Edison’s Technology Test Centers. The findings have provided valuable information for understanding and improving the operation and performance of open vertical refrigerated cases. Results revealed high thermal vulnerability of these cases, identified the impact of energy-efficient equipment on overall case performance, and determined the key geometric
and flow parameters that affect infiltration through the air curtain. These efforts resulted in establishing new and more accurate methodologies and tools for measuring infiltration and optimizing air curtain performance.
