By design, all properly functioning clean rooms are harmless. It is because the vast majority of other advanced clean rooms must wear a full set of anti-static clothing and masks, they will feel uncomfortable in the long-term work. Here's my question. If they've never done it before, they'll have to integrate it. In order to improve labor efficiency, some processing plants are equipped with too many employees and positions in the clean room. Through quantitative analysis, Dongguan clean room is filled with fresh air. Therefore, there is a limit to the total number of air intake. If the total number exceeds a fixed value, everyone can breathe insufficient fresh air and people will feel uncomfortable. More serious cases may even experience chest tightness, shortness of breath and headaches.
Clean rooms designed and built to code for normal maintenance are not a health hazard to long-term workers. First of all, a clean room is a purified, sterile workshop environment that is harmless to the human body. The workshop is a closed space. The purified air is sent in through the purification circulation system and the indoor air is discharged at the same time. According to certain cleanliness requirements, the amount of particulate dust and colonies in the workshop is controlled to maintain a stable clean state. At the same time, with the assistance of air conditioning and ventilation system, the temperature and humidity of the clean room is kept within a certain range to ensure the quality of product process production and protect the comfort of personnel.
In order to meet the comfort of the personnel in the clean room, clean room has a design standard, the amount of fresh air per person per hour shall not be less than 40m3 / h. Therefore, in the design and construction of the clean room, it is necessary to understand the number of stations in the clean room and the number of people working for a long time in order to grasp the total amount of fresh air required for the clean room.
