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 core 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 in everyday life this does not pose a threat to us, except for cases when the concentration of a harmful substance exceeds the norm many times over, for the production of medicines, for rooms with patients, and, most importantly, for the production of microcircuits, all these small particles pose a serious danger. Having fallen on a microcircuit during the production process, even a single speck of dust can ruin it and send it to the scrap. So what to do and how to deal with it?

History of cleanrooms

Back in 1860, the idea arose of a room where there would be a minimum amount of harmful particles in the air. Then, of course, it was not about microcircuits, but about patients whocontact with contaminated air during the operation could be harmful. In order to create an air flow regulator or excess pressure in an adjacent room, it has not yet reached, but the first attempts to control the parameters of the air flow were made already at that time. Over time, technology has evolved, and by the twentieth century they came to their most logical application - the arrangement of a small sterile room with installed ventilation, air filters and air currents that ensure its continuous circulation, as well as insulating clothing for personnel.

Cleanroom Development

Small clean rooms still operate on a similar principle today, the only thing that has changed is more accurate calculations of air flow and pressure. Classification of cleanrooms today uses parameters that show the amount of particles suspended in the air. To ensure the accurate functioning of such systems, RRVs are used - air flow regulators - ventilation units, air intake and air distribution devices, filters and sensors. ESD raised floors are most commonly installed in high-end cleanrooms. Diffusers are built into such raised floors, that is, ventilation grilles that increase the unidirectional air flow. The constant development of microelectronic components and the ever-shrinking of their physical dimensions means that the requirements for cleanrooms are constantly increasing. More and more precise sensors and regulators are needed for their functioning.air flow, more and more advanced filtration and grounding systems, and ever higher demands are placed on personnel. Thus, today the design and operation of cleanrooms has become a whole branch of science.

Home ventilation systems

Agree that no one needs such difficulties in everyday life. However, creating a microclimate that is comfortable for living is also an important task. All houses have general house ventilation systems, but, unfortunately, they often fail to cope with their task of creating a microclimate. And in the worst case, residents expect unpleasant odors from the air duct - in this case, you have to install filters yourself.

So how to make a comfortable microclimate in the apartment? Air conditioners with air flow regulators, of course, help with this. 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, it is definitely worth it.
