摘要
针对光伏交流冰箱系统的工作特性进行实验研究,在空载和负载条件下对所构建的系统的运行性能进行测试。研究发现,在冰箱内放入5、6、7 kg水时,水的冷却速率分别为1.94、1.34、1.23℃/h,冰箱耗功分别为1.1、1.9、2.1 kWh,系统性能系数(COP)分别为0.24、0.29、0.34。在相同辐照强度条件下,负载质量越大,冰箱功耗越高,系统COP越大,从冰箱的使用寿命和系统的经济性考虑,在应用光伏冰箱时应尽量避免箱内负载过大或超负荷使用。
Abstract： The operating characteristics of photovoltaic AC refrigerator in different loadong conditions were tested in the established experimental platform. The results show that the cooling rates of water are 1.94, 1.34 and 1.23 ℃/h, the power dissipations of the refrigerator are 1.1, 1.9 and 2.1 kWh, the system＇ s coefficient of performance （COP） are 0.24, 0.29 and 0.34, respectively when there are 5, 6 and 7 kg water in the refrigerater, respectively. The results also show that when the radiation intensity condition is same, the greater the load quantity is, the higher the power consumption of the refrigerator and the larper the COP are. Therefore, considering lifetime and economy of refrigerator, the large and super loads in refrigerator should be avoided.
