【摘要】：在分析準(zhǔn)并網(wǎng)技術(shù)節(jié)能工作原理的基礎(chǔ)上,探討市電和光伏發(fā)電混合驅(qū)動(dòng)的空調(diào)系統(tǒng)的組成及原理,分別對(duì)太陽(yáng)電池的光伏特性,蓄電池的工作原理,直流壓縮機(jī)的工作特點(diǎn),太陽(yáng)能光伏直流空調(diào)器的能效及經(jīng)濟(jì)性進(jìn)行分析。建立實(shí)驗(yàn)平臺(tái),與常規(guī)空調(diào)進(jìn)行對(duì)比實(shí)驗(yàn)。實(shí)驗(yàn)結(jié)果和理論分析表明:太陽(yáng)能光伏直流空調(diào)器在白天單獨(dú)運(yùn)行時(shí)可節(jié)約市電70%,全天連續(xù)運(yùn)行可節(jié)約市電40%~78%,其綜合能效比約為常規(guī)空調(diào)的3倍。為保證太陽(yáng)能光伏直流空調(diào)器良好的節(jié)電能力,建議其最大運(yùn)行時(shí)間為白天4 h,夜間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.
