A low-cost and thermodynamically efficient implementation of a two-stage refrigeration system applied to a retail refrigerator. The invention includes a simple and easily manufactured thermally efficient and low-cost evaporation unit. The invention further includes a thermal energy storage module and an energy efficient control protocol to maintain steady temperatures in the fresh and frozen food sections, to permit energy efficient defrosting of the heat exchange surfaces in the freezer section, and minimize losses associated with condensing unit on-and-off cycling.
