中文摘要 | 溫室之通風口覆蓋防蟲網以防止害蟲侵入為本省溫室普遍使用的方法,於自然通 風的溫室因防蟲網而產生通風型態的變化,導致內部形成相異於一般通風口之溫度環境。為 探討有無裝設防蟲網對溫室內溫度環境之影響,本研究以對照比較的方法,模擬不同通風裝 置之自然通風溫室,量測其內部溫度變化狀況。結果指出,溫室通風口覆蓋防蟲網後,因防 蟲網的減風、整流等通風特性之影響,造成溫室自然通風量的滅少及流入溫室內空氣的亂度 受到衰減等因素,導致溫室內部溫度的昇高,並促增溫度分佈不均一的現象,尤其對溫室內 垂直方向的溫度分佈有強烈之影響,在側窗高度以上的空間則形成顯著的高溫現象。 |
英文摘要 | The device of greenhouse ventilator covered with insect screen is comm only used in Taiwan to prevent the injurious insects from intrusion.In a naturally ventilated greenhouse with vetilation device covered by insect screen, the interior temperature is different from that of a device without screen. The purpose of this paper is to investigate the effects of insect screen on interior temperature with different ventilation devices in a natural ventilation greenhouse. The results showed that the greenhouse with an insect screen device on ventilation opening has higher and uneven interior temperature. This phenomenon may be resulted from the nature of insect screen that it cuts down the air flow and adjusts the air current, As a result, in the airspaces above the side windows will show the uneven temperature distribution. |
