Summary

The electricity consumption for air conditioning and refrigerated cases in large supermarkets represents a substantial share of the total electricity consumption. The energy efficiency of supermarkets can be improved by optimizing components design, recovering thermal and refrigerating energy, adopting innovative technology solutions, integrating the HVAC system with medium temperature and low temperature refrigeration plants and, finally, reducing thermal loads on refrigerated cases. For the purpose of investigating the performances of different lay-out and technology solutions and of finding the potential for improving the performance over the traditional systems. In the analysis were considered chiller and heat pump working with R410A, normal temperature plant working with R404A and low temperature plant working both with R404A and R744. The investigated solutions enable an annual energy saving close to 20% with respect to the baseline solution.
