在印度，有几个地方的电力不能持续供应，因此无法保存疫苗，人们正在失去生命。基于太阳能的冰箱可能会解决这个问题。通过光伏电池板产生的电力可以用来驱动制冷系统。本文对太阳能电冰箱单机运行进行了参数研究，找出了光伏电池板功率、电池容量和绝缘水平的最佳组合。利用暂态仿真软件(TRNsys)对光伏制冷系统进行了仿真。该系统由50千伏L容量的冰箱、24千伏电池组、1千伏安逆变器和带充电控制器的光伏电池板组成。用实验数据对仿真模型进行了验证。所使用的参数包括：光伏阵列中光伏电池板的瓦数、电池组的容量和冰箱中绝缘的变化。结果表明，在无栅极电源的SPV上运行一台绝缘层厚度为25 mm的电冰箱是可行的，电池板阵列功率为320W，电池容量为50Ah.随着绝缘厚度增加到50W mm，那么200W的面板容量足以驱动冰箱。
In India, there are several places where the electrical power is not continuously available therefore vaccine preservation is not possible and people are losing their lives. Solar energy based refrigerators may overcome the issue. The electricity generated through photovoltaic panels can be used to drive the refrigeration systems. In this paper, a parameter study is carried out to find out the best combination of the PV panel wattage, battery capacity and insulation level to operate the refrigerator stand-alone on solar power. The transient simulation software (TRNSYS) is used to simulate the PV based refrigeration system. The system consists of a refrigerator with 50 l capacity, 24 V battery bank, 1 kVA inverter, and PV panels with charge controller. The simulation model has been validated with experimental data. The parameters used are: wattage of PV panels in PV array, capacity of the battery bank and variation of insulation in refrigerator. The results conclude that it is feasible to operate a refrigerator (25 mm insulation thickness) on SPV without grid power with 320 W panel arrays with 50 Ah battery capacity. As the thickness of insulation is increased to 50 mm then 200 W panel capacity is sufficient to drive the refrigerator.
