Abstract

New refrigeration system configurations and other innovating technologies in retail supermarkets need to be considered to reduce energy use and greenhouse gas emissions. In supermarkets, there is a strong interaction between the refrigerated display cases, supermarket structure, internal machinery, customers, and the store's HVAC system. The impact of these interactions on the energy and carbon emissions of a medium sized supermarket in Paris was modelled using EnergyPlus™. The results were calibrated against a typical UK store and validated against the Paris store. The effects of applying the technologies identified to have the greatest potential to reduce carbon emissions (changing the refrigerant to R-744, switching from gas to electrical heating and adding doors to chilled cabinets) were modelled. The impact of climate change on ambient temperature and the impact of changes to the grid conversion factor were predicted for the store in Paris from 2020 to 2050.

利用 EnergyPlus 建立巴黎一家超市的能源消耗模型，以减少能源使用和温室气体排放

零售超市需要考虑新的制冷系统配置和其他创新技术，以减少能源消耗和温室气体排放。在超市中，冷藏陈列柜、超市结构、内部机械、顾客和商店的暖通空调系统之间存在着强烈的相互作用。我们使用 EnergyPlus™ 模拟了这些相互作用对巴黎一家中型超市的能源和碳排放的影响。模拟结果与英国的典型商店进行了校准，并与巴黎的商店进行了验证。模拟了应用被认为最有可能减少碳排放的技术（将制冷剂改为 R-744、将燃气加热改为电加热以及在冷藏柜上加装门）所产生的影响。预测了 2020 年至 2050 年气候变化对环境温度的影响以及电网转换系数变化对巴黎商店的影响。

期刊介绍： The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling. As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews. Papers are published in either English or French with the IIR news section in both languages.
