Significant parameters for energy consumption in frozen food area of large supermarkets.

Author(s) : ORPHELIN M., MARCHIO D., BECH S.

Summary

The thermal behaviour of large supermarkets is dominated by internal gains. Specifically, refrigerated and frozen food display units area is characterized by cool loads created by commercial cases, which are also moisture traps. A coupling approach of air conditioning with display cases operation is proposed in this paper. The significant vertical stratification of air has to be considered to calculate electric consumption of display cases. Heat and moisture exchanges are calculated and typical values are given. The study gives new elements to answer the questions: how the energy balance is affected by the ambiance setpoints, how interactions between display freezers and air conditioning systems can be characterized.
