中文摘要:

      针对我国冷柜需求不断增加，耗电量增长带来的碳排放和环境污染问题，设计了一套在离网状态下运行的光伏冷柜系统，并使用TRNSYS和MATLAB软件对该系统进行了联合仿真。以气象参数、热力性能、经济效益和环境效益作为评价指标，使用熵权-TOPSIS法对光伏冷柜系统在全国五种不同气候区域内，进行了适用性研究。结果表明设计的光伏冷柜系统在以大连和乌鲁木齐为代表的区域内，具有较好的热力性能和经济效益，CO2年减排量分别为583.2 kg和546.2 kg，环境效益最高，其综合得分分别为0.731和0.645，适用性强，光伏冷柜系统可以率先在该地区推广使用。

英文摘要:

      To address the increasing demand for refrigeration cabinets in China and the associated carbon emis-sions and environmental pollution caused by rising electricity consumption, an off-grid photovoltaic refrigerated display cabinet system was designed. TRNSYS and MATLAB software were employed for co-simulation of this system. Using meteorological parameters, thermodynamic performance, economic benefits, and environmental impact as evaluation indicators, an entropy-weighted TOPSIS method was applied to assess the system's applicability across five distinct climate zones in China. Results demonstrate that the designed photovoltaic refrigeration system exhibits superior thermody-namic performance and economic viability in regions represented by Dalian and Urumqi, with annu-al CO2 emission reductions reaching 583.2 kg and 546.2 kg respectively. These areas achieved the highest environmental benefits, recording comprehensive scores of 0.731 and 0.645, indicating strong regional applicability. The photovoltaic refrigeration system shows promising potential for prioritized implementation in these regions.
