Carbon dioxide refrigeration with heat recovery for supermarkets

This paper describes the outcomes of a research project that investigates sustainable heating and cooling solutions for retail applications using a carbon dioxide (CO2) natural refrigerant (R744) for food refrigeration. The paper presents the findings from an applied research study on a booster CO2 (R744) system with high and medium temperature heat recovery. The paper includes a description of the conceptual design and a computer model along with its validation based on some experimental results. The energy consumption and carbon emission reduction are investigated using this novel system based on an existing supermarket as a case study. This is the version of record
