【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。
[Abstract]:Based on the analysis of the energy-saving principle of the quasi-grid-connected technology, the composition and principle of the air-conditioning system driven by the hybrid drive of municipal electricity and photovoltaic power generation are discussed. The photovoltaic characteristics of solar cells, the working principle of batteries and the working characteristics of DC compressors are discussed respectively. The energy efficiency and economy of solar photovoltaic DC air conditioner are analyzed. The experiment platform is set up and compared with the conventional air conditioning. The experimental results and theoretical analysis show that the solar photovoltaic DC air conditioner can save 70% of the electricity in the daytime and 40% of the electricity in the continuous operation of the whole day. The comprehensive energy efficiency ratio of the air conditioner is about three times as high as that of the conventional air conditioning. It is suggested that the maximum operating time of the solar photovoltaic DC air conditioner should be 4 hours during the day and 2 hours at night in order to ensure the good power saving ability of the solar photovoltaic DC air conditioner.
