摘要
在分析准并网技术节能工作原理的基础上,探讨市电和光伏发电混合驱动的空调系统的组成及原理,分别对太阳电池的光伏特性,蓄电池的工作原理,直流压缩机的工作特点,太阳能光伏直流空调器的能效及经济性进行分析。建立实验平台,与常规空调进行对比实验。实验结果和理论分析表明:太阳能光伏直流空调器在白天单独运行时可节约市电70%,全天连续运行可节约市电40%~78%,其综合能效比约为常规空调的3倍。为保证太阳能光伏直流空调器良好的节电能力,建议其最大运行时间为白天4 h,夜间2 h。
Based on analyzing the working principle of quasi grid energy-saving technology, the composition and principle of air conditioning system driven by solar photovohaic generation and city power grid were discussed. The photovohaic properties of solar ceils, the working principle of storage battery, the working characteristic of DC compressor, the energy efficiency and economy of the solar energy air conditioner were analyzed, respectively. Setting up the experimental platform, the compared experimental tests are carried out with the conventional air conditioner. The experimental results and the economic analysis showed that the solar energy air conditioner can save mains electricity more than 70% at summer daytime and 40%-78% in a whole day. The comprehensive energy efficiency ratio is 3 times of the conventional air conditioner. In order to ensure the energy saving ability, the suggested maximum operating time is 4 hours at daytime and 2 hours at night.
