Abstract

The invention belongs to the field of fresh air and air purifying field, and provides a control system for PM2.5 of a classroom and a working method of the control system. A set of PM2.5 control unitsis separately arranged on a front door and a rear door of the classroom; each PM2.5 control unit comprises fresh air purifying equipment, a PM2.5 sensor, an air curtain machine and a travel switch, wherein the PM2.5 sensor is arranged at one side of the door, the air curtain machine is arranged above the door, the output end of the PM2.5 sensor is connected with an input end of a comparator, theoutput end of the comparator is connected with fresh air purifying equipment after passing through a PID air speed regulator, and the output end of the comparator is connected with the air curtain machine after passing through the travel switch and a deviation recognizer. The control system is convenient, efficient and reliable to use, can form an air curtain after the air curtain machine is started, inhibits outdoor PM2.5 from entering the room, and effectively solves the problem that indoor PM 2.5 exceeds standards as the classroom door is opened and closed.

Description

technical field [0001] The invention belongs to the field of fresh air and air purification, in particular to a classroom PM2.5 control system and a working method thereof. Background technique [0002] In recent years, due to the air pollution caused by smog in our country, the indoor air quality of campus has attracted more and more attention. The outdoor PM2.5 remains high, and indoors due to the large number of students, the air pollution is serious. The indoor air quality of the campus can be said to be internal and external troubles, and it is urgent to solve the indoor air quality of the campus. [0003] Now all schools are promoting fresh air into the campus and installing fresh air purifiers in classrooms. The campus fresh air purifier is to discharge the indoor polluted air to the outside, and the outdoor fresh air is sent into the room after being purified. The fresh air and polluted air are energy recovered by the energy recovery device, so as to maintain the a...
