ENCO-RL性能防风防雨通风百叶

ENCO-RL性能防风防雨通风百叶系统特点l 叶片采用铝合金材质，美观、大气、还具有很强的防腐蚀功能。l 叶片两侧*特排水槽，在遮阳、通风、采光的同时，还能有效防雨防风。**防暴风雨 英国建筑服务研究与信息协会（BSRIA）质量认证l 适合特殊无电源环境。l 百叶颜色可根据客户的要求而定。l 有单层、双层、三层多种类型可选。  ENCO-RL Performance louvre The principal objective of Ventilation (or Performance) Louvre systems is to allow the passage of air, whilst providing a measure of protection against the rain.Specifying performance has not been helped by conflicting technical information given by louvre manufacturers which quotes percentage free areas measured in different ways, namely as resistance to airflow and aerodynamic coefficients alternatively.      Design considerations include:Site location and exposureSeverity of local (site) weather conditionsLocation and exposure of louvres on buildingAirflow rate and direction through louvreMaximum acceptable pressure dropDegree and depth of water penetration acceptableSpecial solutions for sloping applications· Single bank,Double bank,Triple bank for optional.For a true comparison of performance, the aerodynamic coefficient and the degree of rain defence effectiveness are the only sensible measures ,Approved by BSRIA UK。
