    摘要:

    試驗采用Fans assessment numeration system（FANS）為現場監(jiān)測系統(tǒng)，利用位置上下移動持續(xù)運行的螺旋槳風速計和靜壓傳感器對風機通風性能進行測試。試驗共測定3個玻璃溫室內3種類型共9個排風風機在不同工況下靜壓5.0~61.5Pa范圍內的通風量和能源消耗。結果顯示，風機防護網的存在及清潔狀況對通風量的影響低于5%；塑料百葉窗風機比相同配置的鋁制百葉窗風機通風量和能效分別平均高13.1%、15.1%；參數完全相同的風機能效差異最高達12.7%；膠帶驅動的風機轉速減少16.1%時通風量平均降低38.7%；溫室內靜壓超過30Pa時風機能耗顯著增加。

    Abstract:

    Fans assessment numeration system (FANS) was taking for testing the ventilation for each fan at the range of static pressures from 5.0Pa to 61.5Pa under different operating conditions. The results suggested that the existence and cleanliness of the fan safety guard reduced ventilation by less than 5%. The ventilation and efficiency of fans fitted with plastic shutters were 13.1% and 15.1% higher than the fans with aluminum shutters. The most difference of fans efficiency with same parameters reached to 12.7%. The average ventilation was reduced by 38.7% when the rotational speed drove by belt reduced by 16.1%. The energy consumption significantly increased when static pressure was more than 30Pa.
