Abstract

In grocery stores, space conditioning and refrigerated display cases interact, making it difficult to study energy conservation through architectural ideas. The purpose of this study is to determine the indoor enthalpy based on the leakage heat of the display case and the space conditioning load, and to devise a method for calculating store energy by combining the space conditioning load calculation and the refrigeration load calculation. In this report (2nd report), we will report the display case load prediction method and the refrigerator power consumption calculation method using the display case cooling load characteristics clarified in the previous report.
