As we all know, fresh air plays a very important role in people’s survival and health. If unclean air is inhaled by people for a long time, it will cause physical discomfort and even death. Get ill. Especially in winter, stale air is a problem when people travel. Outdoor air is very important, but indoor air is equally important. Indoor fresh air is inseparable from the function of the fresh air system and the use of PTFE composite filter paper.
Many people may have this idea. It is a lot easier to send their children to kindergarten, but there is a problem that many parents have. Neither realized it. There are many children in kindergartens and the space is relatively closed, making it easy for cross-infection. This is also the main reason why children in kindergartens are easy to get sick. Also, children have very weak awareness of hygiene. Sometimes they eat without washing their hands after playing with toys, which can easily ingest tiny bacteria into their bodies.
The centralized air conditioning system installed indoors generally uses a conventional chiller as the cold source, and the air conditioning system is mainly an all-air system or a fan coil system. When the air conditioning system is used in school buildings, the disadvantages are: the air conditioner is noisy, the condensation water tray is easy to breed small bacteria and microorganisms, and the indoor air quality is poor; the indoor relative humidity is high, and the human body feels uncomfortable. The PTFE composite filter paper can filter the air very well, with a filtration efficiency of 99.9999%.
The purification methods of fresh air fans on the market are mainly electrostatic dust collection and physical purification by filters. The former will produce trace amounts of ozone during the purification process, and the latter will The filter purification level ranges from H9-H13. In comparison, the filter purification is more reliable to prevent the released ozone from causing discomfort to individual students.
In addition to ventilation, a very important function of the fresh air system is to filter pollutants in the air. Therefore, the filter of the fresh air system is very important in the entire system. important part. General fresh air system filters can be divided into three levels, namely primary filter, medium filter and filter
