幼儿园/学校：为什么学校需要新风系统？

3-18 year-old children spend more time in school/kindergarten than in any other place. Their health depends on an healthy environment in the classroom. In accordance with National Indoor Air Quality Standards1 nurseries, kindergartens and primary and secondary schools shall conduct testing of indoor air quality.
Outdoor air pollution is also not a trivial matter: schools in Beijing occasionally had to be cancelled due to serious air pollution2. Thus, it is crucial to provide air purification for classrooms in heavily-polluted areas. In recent years, air purifiers get popular, but they fail to solve the issue of high CO2 levels. Without external air circulation, too little oxygen is available.
Studies have shown that students can concentrate better and perform more actively in the classroom with sufficient oxygen. Reading test performance increased about 13 percent3. But when air conditioners are switched on in summer or winter, windows and doors usually remain shut. For comfortable room temperature and fresh air at the same time, our fresh air systems is the solution.
In the flu season, if one student is sick, the whole class may get infected. Continuously fresh air coming through the system helps prevent cross-infection, because it filters pollen and other allergens, also helps relieve symptoms of asthma and respiratory allergies. With better air quality, students will be healthier and thereby their parents feel more secure.

3-18岁的未成年人在校园的时间比其他地方更长，教室环境与他们的身体健康息息相关，而在优质空气环境中成长的孩子更健康更开朗。按照国家《室内空气质量标准》1 相关规定，托儿所、幼儿园及中小学应当对室内空气质量进行检测。
室外空气的污染更不容小觑，北京曾因为严重空气污染而停课2，教室内的空气净化在雾霾天气显得尤为必要。近年来，空气净化器开始受到青睐，但教室由于人员密集，CO2含量过高，氧气需要通过开窗通风来补充，而空气净化器在密闭空间才能更有效工作，其本身并不能完成与外界空气的循环。
有研究表明在氧气充沛的室内空气状态下，学生更容易集中注意力，课堂表现也更活跃，阅读考试的成绩提升约13%3。如果在夏季、冬季开启空调的条件下，教室几乎是全密闭的环境，既要拥有舒适室内温度又要保证新鲜空气进入室内，新风系统便是一个可以两全的解决方案。值得注意的是在流感高发季节，常会出现一人得病，全班遭殃的情况，而源源不断的新风不仅可以防止交叉感染，因其可以吸附花粉等过敏原，也有利于缓解哮喘和呼吸道过敏的症状。有更好的空气质量陪伴，学生更健康，家长也会更放心。
