Research on Power Consumption Calculation Method for Refrigerating and Space Conditioning Considering Heat Balance in a Grocery store

Abstract

In grocery stores, spatial coordination and refrigerated display cases interact, making it difficult to study energy conservation through architectural ideas. The purpose of this research is to find the indoor enthalpy from the leaked heat of the display case and the space conditioning load, and to devise a method to calculate the energy of the store by combining the space conditioning load calculation and the refrigeration load calculation. In this study, we devised the following three points. 1. Store cooling load prediction method and power consumption calculation method using display case cooling load characteristics. 2. A generalized model for grocery store vertical temperature gradient using CFD analysis results. 3. Energy consumption calculation method considering the balance of the three loads of cooling, building and space conditioning. Then, we confirmed the validity by comparing with the measured values, and performed simulations under various conditions.
