Study on Energy Consumption of Apple Cold Storage based on Solar Photovoltaic Power Supply Mode

本文以西安某50 t苹果冷库为例,建立光伏冷藏库发电系统,研究冷藏库最大时刻耗电量与光伏板单位面积发电量的相适性,获得光伏系统容量,并预测实时天气下太阳能光伏-冷藏库系统电量供需模式。研究结果表明,除10月份外,其余月份光伏系统均可满足冷藏库最大时刻耗电需求。其中10月份光伏发电率较低为57.06%,可结合冷藏库10月份实际运行情况,进行节能措施,减少冷库能耗,提高光伏系统电量匹配性。该研究结果可对光伏冷藏库系统方案的设计和优化提供参考和依据。

This paper uses a 50 t apple cold store in Xi’an as an example to establish a photovoltaic power generation system to study the adaptability of the maximum power consumption of the cold storage and the photovoltaic power generation per unit area,obtain the capacity of the photovoltaic system,and predict the power supply and demand model of solar photovoltaic refrigerator system under real-time weather.The result show that,except for October,the photovoltaic systems in the rest of the month can satisfy the power consumption demand of the refrigerator at the maximum time.And the photovoltaic power generation rate in October was 57.06%,which can be combined with the actual operation of the cold storage in October to implement energy-saving measures to reduce the energy consumption of the cold storage and improve the match of the photovoltaic system electricity.The research results can provide reference and basis for the design and optimization of the photovoltaic cold storage system.
