SuperSmart - -Report 3
This report serves as a starting point material for training supermarket stakeholders in building new, ecofriendly supermarkets. The report covers building design, refrigeration, heating, ventilation and air conditioning (HVAC), as well as lighting, with the main focus being on the refrigeration and HVAC system.
New, innovative and promising technologies and solutions are introduced, accompanied with case examples from different parts of Europe.
For the refrigeration system, the focus is on CO2-only systems, as this is regarded as the most energy efficient and eco-friendly approach. State of the art CO2 system layouts using ejectors for expansion work recovery, suitable for both warm and cold climates, are presented. An integrated system solution covering both the refrigeration and HVAC, allowing optimal heat recovery, is highly recommended, and a possible system layout for such an integrated approach is presented.
