Use fresh air system on campus benefits are the following: (1) no windows can also enjoy the fresh air of nature; (2) can be run automatically according to indoor air quality, air volume adjustment, without manual operation; (3) ensure that the indoor air quality to meet health standards; (4) to avoid "Air conditioning disease"; effective complement O2 required by the body, enhance students' learning ability (5) to avoid the air conditioning is turned on, the energy loss caused due to window ventilation; (6) to adjust indoor humidity, saving heating costs; (7) the effective exclusion of the indoor variety of bacteria, viruses; (8) professional design and installation, ultra-quiet, does not affect the school. Kindergartens, schools, training centers and new air system kindergartens, schools, training centers and personnel density, mental exertion, stay indoors for a long time, good indoor air quality is to ensure that the intellectual development of the child, a necessary condition for healthy growth! Most places you need to install a new ventilation system, the product of high-tech companies appeal to the community concerned about the child in the classroom air quality, install a new air system! Kindergarten, school indoor air quality status quo Currently, the product of high-tech companies visited the survey found that kindergartens, schools with little fresh air system. Now every classroom desks side by side, the general student population of about 60 people, basically a small classroom full of dignified sitting. Every child in constant exhale carbon dioxide, and everyone in the dissemination appreciate that some students do not pay attention to health shoes smelly, sweaty very serious air smelled classroom. In such a crowded space, open to the parents who have personal experience of parents, it is very uncomfortable! Ventilation window is common practice in the school, in spring and autumn temperatures more appropriate classroom basically all the windows open for ventilation in the cold winters and hot summers, open heating or air conditioning when the classroom is an open part of the basic Students windows for ventilation, sitting in the window feeling very unwell affect children learn, but also result in the loss of a lot of energy! Even so, the indoor air is still polluted state. After KAIR technical staff visited a number of schools survey, carbon dioxide content in the classroom generally reach 2500PPM, even more than 3500PPM (outdoor concentration of carbon dioxide is about 350PPM, over 1000PPM harmful to learn more about carbon dioxide and health) in addition to odor in the air outside of the main problems in the classroom air quality is hypoxia, which seriously affected the children's growth and mental development. In China, the educational conditions across a large gap, we can not require that all classrooms are equipped with a new style, but perfectly placed to install a new ventilation system in the developed regions, we appeal to the relevant departments attach importance to this issue. Kindergarten, school classrooms fresh air of high-tech companies to determine the product based on actual experience, provides the following method for your reference: the classroom based on how much fresh air and the number of classrooms to determine the age of the fresh air of the classroom. Kindergartens, primary schools: 15M3 / H- people, middle, high school, college: 30M3 / H- person. Example: For example, up to 60 people in a classroom, if a kindergarten and elementary school classrooms, fresh air needs 900M3 / H, as a junior high school, high school, college classrooms will need to set the way the classroom 1800 M3 / H kindergarten, school classrooms are air system Children learn from, this requires a new ventilation system to have high winds, low noise performance. General exhaust fan noise due to the relatively large, short life, although proper ventilation solve the problem, but is not suitable for installation in the classroom. Cold regions in the north, the proposed heat recovery equipped with central air system, so ensure good ventilation while maintaining stable room temperature. In the south, you can use fresh air systems without heat transfer. For example, high product pipeline of new fans with low noise characteristics of strong winds, very suitable for classroom installations. Installation of a new air system attention to two issues, one is as even as possible into the fresh air, setting a number of new air vents on the new pipeline, it allows students in each region can breathe fresh air. Another is a new wind switches pay attention to safety and ease of use. Contact: 13373307108 Zhao workers
