室内空气质量 (IAQ) 室内健康环境可以为人们带来舒适感、较高的工作效率、健康感和幸福感。 下载维萨拉暖通空调电子书 室内空气质量监测 室内空气质量 (IAQ) 是用湿度表以及温度和二氧化碳传感器进行测量的,以便确保室内环境对人舒适。尽管人类舒适程度依赖于多种变量的相互作用,但与单纯优化温度相比,通过测量室内空气质量 (IAQ) 来优化相对湿度、温度和二氧化碳可满足更多不同居住人群的舒适要求。 观看下面有关维萨拉暖通空调传感器的视频,或者继续阅读有关湿度如何影响室内空气质量的内容。 湿度是如何影响室内空气质量的? 室内空气中较低的相对湿度会导致人的不舒适。头痛、眼睛发炎、嗓子痛和皮肤干燥都是在非常干燥的室内环境下所表现出的症状。干燥的空气会降低空气对传播感染的自然防御,使人们更容易受到病毒和其他微生物的攻击。除了与干燥低湿度有关的问题之外,过高的湿度也可能会导致问题的发生。这些问题既可能是不健康的生物污染物的生长和扩散,也可能是湿度对建筑材料的损害影响。 通常,人类对湿度不像温度那样敏感。人们通常不会将身体的不适和潜在的健康问题与相对湿度中的变化关联起来。这正是好的测量技术可以帮助支持人感觉的地方。可靠的湿度测量是成功的湿度控制的关键。 二氧化碳级别是如何影响室内空气质量的? 需求控制通风 (DVC) 通过根据占据某一空间的人数对通风进行控制来发挥作用。这样做的目的是通过高能效的通风来为使用者提供良好的室内空气质量。 欧洲 EN 标准 13779(2007 年)将良好的室内空气质量定义如下:“室内空气质量可按二氧化碳浓度进行分类。”这一观点为通过测量二氧化碳并相应控制通风来操控 DCV 确立了基础。该标准还设立了室内二氧化碳级别为 400–600 ppm 的一般预期,该预期稍高于室外空气的一般级别 (400 ppm)。现代通风系统是在这一推论的基础上建立的,以便在保持高能效的同时确保足够良好的室内空气质量。 但实际上,这主要应用于配备了现代通风系统的现代办公室。现场研究表明,一般的办公室环境的二氧化碳浓度为 1,500 ppm,这可能看起来是一个非常高的水平,但认为对人类安全的法律规定甚至更高:在 8 小时的时段内 5,000 ppm 的二氧化碳。 在室内的二氧化碳水平升高时,与 400 ppm 的标准室外水平相比,在 1,400 ppm 的二氧化碳浓度下认知能力(例如危机反应、信息使用和统筹安排)仅降低 20%。一些更为机械的能力(例如信息查找和任务定位)并没有受到过多影响。但是,要求更高级的信息应用的认知能力受到的影响最大。在室内二氧化碳水平升高时,处理更高级的任务会变得困难得多。室内空气质量的准确测量以及更好的通风对在办公室内工作的人的认知能力至关重要。 维萨拉提供各种手持式和固定式室内空气质量 (IAQ) 传感器,以测量相对湿度、温度和二氧化碳。查看我们的所有暖通空调产品和服务。 室内空气质量是用 CO2,温度和湿度传感器测量来确保室内环境对人舒适。尽管人体舒适感取决于多种变量的相互作用,与单纯优化温度相比,温度和相对湿度两者优化将满足更多不同居住人群的舒适要求。二氧化碳 水平是一种反映室内空气质量和人类活动的替代测量指标。 室内健康环境为人们带来舒适感、高效的工作、健康和幸福感。 萨拉提供各种手持式和固定式室内空气质量传感器,以测量二氧化碳、相对湿度和温度。 相关产品 二氧化碳及温湿度变送器GMW90系列 适用于苛刻通风要求应用 壁挂式维萨拉 GMW90 系列 CARBOCAP® 二氧化碳、温湿度变送器特别适用于智能建筑项目。 该系列变送器可测量二氧化碳和温度,并具有额外的湿度测量选项。这些仪器配备满足可追溯和符合性要求的校准证书。使用可在现场调换的智能检测模块就能保持可追溯性。该变送器能融入空间内部设计中...
