Air is something without which it is impossible to imagine our life. We could not exist without him. However, for some technological processes, air is a real danger. How and why - let's try to figure it out.
The essence of the problem
As you know, the air contains microscopic particles of dust and dirt, chemical compounds and aerosol particles, microorganisms and much more. And although this does not pose a threat to us in everyday life, except when the concentration of the harmful substance is many times higher than the norm, for the production of medicines, for rooms with patients, and, most importantly, for the manufacture of microcircuits, all these small particles carry a serious danger. Once on a chip during production, even a single speck of dust can ruin it and send it to junk. So what to do and how to deal with it?
Cleanroom History
Back in 1860, the idea arose of a room where there would be a minimal amount of harmful particles in the air. Then, of course, it was not about microcircuits, but about patients who could be harmed by contact with contaminated air during surgery. Before creating a regulator of air flow or overpressure in an adjacent room, it still did not reach, but the first attempts to control the parameters of the air flow were made in those days. Over time, technologies developed, and by the twentieth century they came to their most logical application - the arrangement of a small sterile room with installed ventilation, filters for air purification and airflows, ensuring its constant circulation, as well as insulating clothing for staff.
Cleanroom Development
Small clean rooms today operate on a similar principle, the only thing that has changed is more accurate calculations of air flow and pressure. When classifying cleanrooms today, parameters are used that show the number of particles suspended in the air. To ensure the exact functioning of such systems, RRV - air flow regulators - ventilation units, air intake and air distribution devices, filters and sensors are used. Most often in high-class clean rooms antistatic raised floors are installed. Diffusers are integrated in such raised floors, that is, ventilation grilles that increase the unidirectionality of the air flow. The constant development of microelectronic components and the constant decrease in their physical dimensions leads to the fact that the requirements for clean rooms are constantly growing. For their functioning, more and more accurate sensors and air flow regulators, more and more advanced filtration and grounding systems are needed, and more and more high demands are placed on personnel. Thus, today the design and maintenance of cleanrooms are becoming a whole branch of science.
Home ventilation systems
Agree that nobody needs such difficulties in everyday life. However, creating a microclimate comfortable for living is also an important task. All houses have common-house ventilation systems, but, unfortunately, they often do not cope with their task of creating a microclimate. And in the worst case, residents expect unpleasant odors from the duct - in this case, you have to install filters yourself.
So how to make a comfortable microclimate in the apartment? In this, of course, air conditioners with air flow regulators help. They allow you to set the exact parameters of the air entering and leaving the room, set the temperature and provide real comfort. And although the pleasure is not cheap, but it is definitely worth it.
