What is ventilation?

What Does ventilation Mean

With origin in the Latin ventilatio , ventilation is a term that describes the act and consequence of ventilating something or someone or of ventilating (that is, letting the air penetrate the body or circulate it in some environment). The word is also used to identify the air currents that arise when ventilating it, the gap, space or opening that makes possible the renewal of air within a place or an artifact and the installation that is used to ventilate a place.

For example: "Please open that window , there is no ventilation here" , "Yesterday my computer burned because I had ventilation problems and I had not realized it" , "The bedroom ventilation is very important to prevent germs from concentrating on the bed ” , “ It is very hot outside, although there is good ventilation in this restaurant ” .

From an architectural perspective , ventilation is a key aspect to take into account since it is about determining in advance how it will be guaranteed that the air can be renewed inside a building , either through the outlet or through a air intake.
The objective of ventilation, in this case, is to guarantee the salubrity of the air and its renewal. It is also linked to the dissipation of smoke in the event of fire and the thermal conditioning of buildings.
The industrial ventilation , moreover, is the system that provides the ability to neutralize or eliminate the presence of gases, dust, smoke or odor in the workplace. What is eliminated through ventilation is usually harmful to the health of workers.
The basic device for any type of ventilation is known as a fan . It is a machine that produces a stream of air thanks to the rotation of its blades, which generates a pressure difference.
Computer ventilation
Computer experts know that it is vitally important to take care of the ventilation of the equipment, to avoid the overheating that often occurs when trying to push its capabilities to the limit and beyond. Processors, for example, are identified by make, model, and speed, among other things; and that speed is the one that the manufacturer estimates can be maintained without burning said component, considering that the consumer will not change the fans (also called coolers) or add others.
And is that in most cases, PCs have a basic and ineffective ventilation , which consists of three fans: one that is placed on the processor, another that has the video card (in the case of relatively recent models because the former had only a heat sink) and one that is in the power supply. The function of each of them is different; the first two provide fresh air over the components to which they are attached, while the third blows the air out of the box.

One way to considerably improve the cooling conditions of a computer is by adding two fans to the above system: one at the front, with the aim of entering as much cold air as possible, and one at the opposite end, below the source and at the height of the processor and the video card, in charge of collaborating with the expulsion of the heat that is generated inside the tower, especially on the part of hard drives and optical disc readers.
When choosing the most suitable fan for each case, it is advisable to consult an expert, instead of venturing to buy being tempted by advertisements, since there are different types of technologies, which offer from higher speed and less noise to cooling to water base .
