The Significance of Pressurization and Ventilation Systems

Filtered air is supplied to a work area by a forced ventilation system. If the functional area’s internal air pressure exceeds the air’s density, dust and contamination will not be able to enter. As a result, this system will keep the working environment clean and ventilated. Natural ventilation is rarely satisfactory unless outside circumstances are excellent, which rarely occurs. The natural supply of fresh air is determined by the temperature difference between inside and outside. It is rare for fresh air to flow into an inhabited space unless a breeze is blowing in the right direction.

As a result, natural ventilation is ineffective when the weather is hot and windless. Additionally, dust can’t enter the building spaces through faulty air ingress control. So, forced ventilation systems are required in the majority of cases, and three alternative methods can be used in this situation.

  1. Extraction/exhaustion of air
  2. Access to fresh air
  3. Sequential extraction and supply

Industrial facilities need to create a pressurization effect to achieve dust proofing, which can typically be achieved by cleaning incoming air if necessary.

The degree of air cleanliness is dictated by the requirements of the process being carried out in an industry, and it can be achieved by using a suitable filter medium such as HEPA, MICROVEE, HDPE, and other high-efficiency filter media.

Let’s explain the difference between ventilation and pressurization systems in detail.

Ventilation System-

Ventilation systems are used to provide enough air circulation in the working area for people’s comfort.

There are two types of systems. In a dry ventilation system, outside air is pumped into the area without cooling. In many circumstances, such systems are installed to pressurize the space. Outside air is cooled here before being introduced into the atmosphere. Cooling can be accomplished using an evaporative cooling system, a typical spray-type system, or Celdec-type cooling pads.

Proper exhaust is required in both of the applications.  Natural air might come through doors and windows, or mechanical air can come from ducts and fans. Roof ventilators are sometimes placed to remove the heat from the area.

Pressurization System-

Pressurization systems are installed to keep the enclosed region at a little higher pressure than the adjacent area. This is done to prevent air, smoke, or gases from leaking into the enclosed region from the adjacent area. All doors and windows are kept closed in this type of application. When any door is opened for any reason, the inside air tends to escape and no outside air enters the enclosed region.

Electrical Rooms, Pharmaceutical Blocks, air-conditioned areas, engine assembly areas, lift machine rooms, compressor rooms, and staircases are all places where the system can be used.
