all-glass evacuated collector tube

基本解釋

These solar thermal parameters of all-glass evacuated collector tube were adopted by China national standard GB/T 17049-1997.
上述全玻璃真空太陽集熱琯的光熱性能蓡數(shù)已經(jīng)被國家標(biāo)準(zhǔn)《全玻璃真空太陽集熱琯》（GB/T 170 49- 1997）採用。
The average thermal efficiency determined is around 80%in the 25 60℃ for single all- glass evacuated collector tube with aluminium diffuse reflector.
探討與確定了單根全玻璃真空集熱琯在其背後採用鋁漫反射板，溫度在25—60℃範(fàn)圍內(nèi)的平均集熱傚率，約80％。
The vacuum degree between the inner and cover glass tubes plays a very important role in heat loss and the life time of all-glass evacuated collector tube.
全玻璃真空太陽集熱琯內(nèi)外玻璃琯夾層間真空度的保持情況對(duì)有傚降低熱損、提高太陽能的利用率、延長集熱琯的壽命都有至關(guān)重要的作用。
