家用太阳能制冷系统设计

Design of Home-Based Solar Refrigeration System

本文利用太阳能电池组件、蓄电池、光伏控制器连接小型车载冰箱来实现适合家庭应用的太阳能制冷系统。针对使用地点(南京)的气候特点,对电池列阵及蓄电池的大小容量进行了计算,结果显示家用太阳能制冷系统不适合采用大量的蓄电池,同时采用大面积的电池组件也缺乏可操作性。进一步给出整套装置的集成方案设计,利用太阳能产生的电能作为峰时电价时的辅助能源,最后进行系统的成本分析及方案优化,改进方案既达到节电目的又降低整体系统的体积和最终成本。在家庭应用领域,太阳能利用技术尤其光伏发电技术存在诸多问题,有待进一步改进。

This article aims at designing a solar refrigeration system suitable for family application, by connecting solar cell module, storage battery and photovoltaic controller with a small car refrigerator. According to the climate characte-ristics of the local place (i.e., Nanjing), the number of module array and the capacity of storage battery are calculated. Home-based solar refrigeration system is not suitable to contain too many batteries, at the mean time;adopting large area of cell module is not economic. Based on the above consideration, the final integrated solution design of a com-plete set of equipment is given. The electrical energy from solar energy is just as an auxiliary energy when electricity price is in the peak. Finally the cost analysis and optimization of the system are given. The improved solution can save electricity as well as reduce the volume and cost of whole system. There are still many problems needed to be solved for solar energy technology application, especially photovoltaic power generation.
