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管的光熱性能參數(shù)已經(jīng)被國家標(biāo)準(zhǔn)《全玻璃真空太陽集熱管》（GB/T 170 49- 1997）采用。
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管在其背后采用鋁漫反射板，溫度在25—60℃范圍內(nèi)的平均集熱效率，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管內(nèi)外玻璃管夾層間真空度的保持情況對有效降低熱損、提高太陽能的利用率、延長集熱管的壽命都有至關(guān)重要的作用。
