摘　　要：为进一步降低冷库系统能耗,实现节能减排的目的,本文提出了一种新型光伏驱动蓄能型冷库系统。基于TRNSYS仿真软件,构建了太阳能-冷库蓄能型热力耦合模型,以夏季工况下秦皇岛市某果蔬冷库为研究对象,对该冷库系统进行数值模拟和理论分析。结果显示,库内温度可以一直稳定维持在2.5~4.0℃范围内,系统COP最高可达1.63,系统运行功率在0~0.8 kW,系统累计制冷量达到了153.2 kWh,17天累计能耗为91.5 kWh。通过计算17天共节省电能59.4 kWh,节省用电费用30.294元,降低碳排放46.629 kg,一定程度上提高了冷库运行的经济效益,并且对实现“碳中和”具有现实意义。In order to further reduce the energy consumption of cold storage system and achieve the purpose of energy saving and emission reduction,a new type of photovoltaic driven energy storage cold storage system is proposed in this paper.Based on the TRNSYS simulation system,the solar-cold storage thermal coupling model was constructed.Taking a fruit and vegetable cold storage system in Qinhuangdao City in summer as the research object,the numerical simulation and theoretical analysis of the cold storage system were carried out.The results show that the temperature in the library can be stably maintained within the range of 2.5~4.0℃,the system COP can reach 1.63,the system operating power is in the range of 0~0.8 kW,the system cumulative cooling capacity is up to 153.2 kWh.The cumulative energy consumption for 17 days is 91.5 kWh.Through calculation for 17 days,a total of 59.4 kWh of electric energy is saved,electricity cost is saved 30.294 yuan,carbon emission is reduced 46.629 kg,to a certain extent,improve the economic benefits of cold storage operation,to achieve the purpose of energy conservation and emission reduction.
