Shanxi kindergarten fresh air system
The fresh air system of the kindergarten in Shanxi was of great significance. From the point of view of necessity, indoor air pollution was seriously harmful to children.

The project was purchased through public bidding, with a budget of 430,000 yuan (maximum price), and a supply and installation period of 15 calendar days. The project was specifically targeted at small and medium-sized enterprises. The procurement process included obtaining the bidding documents from the Shanxi Province Government Purchasing Network, submitting the bidding documents, and other related steps. In the end, Shanxi Wanyou Information Technology Co., Ltd. won the bid with a bid of 426,750 yuan. The equipment related to the fresh air system provided included the fresh air system, control system, consumables, etc. of Miwei brand. Wanyou Company was responsible for the construction and installation. The reason for the installation of fresh air systems in the kindergarten included the possibility of outdoor smog, vehicle exhaust, chemical discharge and other pollution affecting the indoor air quality of the kindergarten in some areas of Shanxi. In addition, when there are many people in the classroom, closing the doors and windows to block the noise will cause carbon dioxide to exceed the standard; when the outdoor air quality is poor, opening the window for ventilation will easily cause the increase of the PM 2.5 value and cause pollution; even if the indoor Formalide is released within a safe range, the total amount concentrated in the classroom space may exceed the standard; In addition, good ventilation can reduce the probability of indoor infection. Children's resistance is poor. The fresh air system helps to protect the health of children and improve the overall environmental quality and competitiveness of the kindergarten.
