aSENSE Duct

安装在通风管道中的CO₂传感器。

特点

  • 在正常情况使用下,免维护
  • 应用于按需控制通风(DCV)策略时,有助于降低能源成本
  • 内部自动自诊断功能
  • 标配2个模拟输出(V/mA)。可选继电器输出
  • 可选经济高效的RS485通信接口
  • 可选内部双通道记录器

aSENSE Duct是一款安装在通风管道中的免维护红外二氧化碳传感器。该装置配有工业外壳(防护等级IP65),带有管道探头。该产品旨在通过将测量的二氧化碳和温度值传输到系统的主设备(Master) 或DDC来控制通风。该变送器设计灵活,适用于多种不同的通风策略。

根据大多数建筑法的规定,在人员长期停留的房间内,新鲜空气流量至少应为7升/秒,如果房间里的人是工作负荷较轻的成年人,当室外的CO₂浓度为350 ppm,那么这种空气流直接对应室内的CO₂浓度为1040 ppm。

根据国家职业安全和健康委员会(the National Boards of Occupational Safety and Health)的规定,CO₂浓度可以作为室内空气质量(IAQ)的指标,并始终把CO₂浓度低于1000ppm作为目标。
