Abstract

The purpose of this study is evaluating energy consumption and the indoor thermal environment of grocery stores, which using frozen and refrigerated display cases, by taking temperature distribution into consideration. In this report, store CFD models which can evaluate the indoor temperature distribution were adopted to study the influence, made by temperature or ventilation flux altering, on energy consumption of grocery stores. The results indicate that the mixture of indoor air, no matter affected by outside influx or space conditioner set temperature, contribute to the energy consumption of display cases and space conditioners.
