Nowadays, environmental pollution is becoming more and more serious, and more people pay attention to the quality of life. Fresh air systems are gradually installed in many areas, and some schools are also gradually installed. There are many students in the school. The area where students spend a long time in a day is the classroom. Therefore, the classroom should be naturally ventilated from time to time, and some harmful substances should be considered to ensure the freshness of indoor air, so that students can study comfortably, and the installation of school fresh air system is a very good choice. In fact, the design and installation plan of the school fresh air system is also very important. Today, let's introduce to us how to design and install the plan of the school fresh air purifier.

At this stage, for the internal natural environment of the school, the school is more suitable to install a two-way flow school fresh air purifier. According to the cyclone circulation system, it can be divided into unilateral flow and bidirectional flow. The single side flow fresh air system is the "forced exhaust system, of course, air supply". The basic principle of the system software is to generate indoor negative pressure with the help of the adsorption force caused by the work of the server, and send the turbid gas outdoors according to the air supply pipeline. In order to better balance the negative pressure in the room, The relatively fresh air outside the room shall enter the room through the air inlet installed first, so as to achieve the purpose of ventilation.

However, if the single side flow fresh air system is installed in the school's fresh air system, the gas containing haze directly enters the room without any solution, and the harm of environmental pollution to students is not reduced. It is not allowed to save the kinetic energy of indoor air quality and increase the kinetic energy consumption of air conditioning and ventilation equipment according to the heat exchanger. When the school fresh air system chooses to install a two-way flow fresh air system, the above problems will not occur. The two-way flow fresh air system, namely "forced exhaust system, forced air supply" system software, is composed of a group of forced air supply system software and a group of forced ventilation system. The air supply mode is changed from natural air supply to forced air supply, the air inlet of the air supply hole is more active, the fresh air system is sent into the room by the pipeline of the air supply system software, and the turbid gas is centrally discharged outdoors according to the exhaust pipeline, and the actual ventilation effect is more remarkable.

The above is a brief and detailed introduction to the design scheme and installation plan of the school's fresh air system. The key goal of the school's installation of the school's fresh air system is to worry about the haze weather PM2.5 and give college students a refreshing and healthy learning environment. Therefore, the school's fresh air system should pay special attention to the filtration. There are many types of natural fresh air system, We must choose according to the specific situation.
