Advanced Supermarket Refrigeration / Heat Recovery Systems

This project investigated candidate advanced system design approaches to determine their potential for reducing refrigerant usage and energy consumption for both refrigeration and heating/air conditioning in supermarkets. Advanced supermarket refrigeration system concepts to be considered include, but are not limited to:

  • secondary loop systems
  • distributed compressor systems
  • self-contained display cases


This project aimed to demonstrate and document the benefits of advanced systems design for food refrigeration and space heating and cooling for retail food stores (supermarkets). A specific goal was to identify advanced system design options to reduce the total equivalent warming impact (TEWI) of supermarkets.
