Project Summary

The purpose of this study is to determine the effectiveness of passive Phase Change Materials (PCMs) in cold storage freezer applications. The PCM technology is designed to melt and freeze at a specified temperature based on the specific needs of a particular freezer. By increasing the thermal storage capacity of the freezer, refrigeration load is able to shift to periods where energy is cheaper, while simultaneously improving system efficiency. This report is necessary to help determine if the technology is resulting in a significant energy savings and benefits worthy of adoption into SDG&E’s Energy Efficiency Program and Demand Response Programs.
