Summary

Paper published in poster form during the conference. This paper reviews the guidelines of how to instrument, measure, monitor and evaluate refrigeration systems in supermarkets. The guidelines principles are firstly illustrated for a simple, single stage, refrigeration system: measurements requirements are analysed and the methodology to estimate refrigeration quantities are defined. Estimation for refrigerant mass flow rate and compressor power are more extensively described and their application on real field measurement data presented and discussed. The extension of the guidelines for a more complex refrigeration system is finally presented with focus on centralized systems providing cooling a multiple temperature levels: a HFC system with LT subcooler and a simple CO2 booster system.
