Types of ventilation
Comfort in our lives is largely ensured thanks to ventilation systems. Clean air and an optimal microclimate have become components of everyday life. As you know, a person inhales oxygen and exhales carbon dioxide, which is life-threatening. Particularly important is the issue of updating the atmosphere at work sites and warehouses, and the availability of ventilation in residential buildings.

What is a ventilation system in an apartment, private house, or industrial premises?
Ventilation system — complex equipment for regulating indoor air exchange. The system also influences the microclimate through technical means. Modern ventilation can purify the air flow, humidify it, heat or cool it. Providing air circulation in an apartment, private house and production workshops varies significantly.
As mentioned above, a person emits carbon dioxide - an integral part of life.The air that a person inhales must be saturated with at least 20% oxygen. Lower levels result in headaches at best, and a constant lack of oxygen has a significant impact on well-being.
The air in living rooms must be renewed at least once an hour. In other words, the update rate per hour is 1. This is enough for comfortable living in an apartment or private house. But even so, in kitchen areas the multiplicity increases to 3-5 times.
Air circulation in a closed workshop or warehouse has a high multiplicity. In plants and factories, there are usually other sources of pollution, which means that cleaning must be done more often. For example, in public smoking rooms, which are an integral part of large production facilities, air circulation should occur at least ten times.
Thus, the load on ventilation systems in production is higher than in residential apartments. If in a private house it is possible to update the microclimate simply by opening a window, then in production workshops such an opportunity is practically absent.
Methods for determining the broad classification of ventilation systems
Ventilation can be characterized by 4 types: according to the method of air circulation, purpose, structural structure and working area. Each type has advantages and disadvantages.
Types of ventilation according to the method of forming air flows
Air exchange occurs due to natural draft, which depends on two factors:
- difference in temperatures outside and inside;
- difference in pressure between room and exhaust.
Weather conditions, such as wind, matter.Such systems do not require additional equipment, consume little electricity and are easy to operate.
Artificial, otherwise called mechanical, ventilation operates on the basis of equipment and additional devices, due to which air exchange covers large rooms. Mechanical systems require enormous amounts of electricity to operate. They are completely autonomous and are not influenced by nature.
What types of ventilation are there by purpose?
There are supply and exhaust ventilation. The supply system carries out the influx of fresh air, the exhaust system - the outflow of treated air. The systems are used together. They can also be classified as local - for a specific area, and general exchange - for large workshops.
Types of ventilation systems by area of operation
Types of local ventilation — supply and exhaust systems. When using this type, air is supplied to a selected area, and only the place where carbon dioxide accumulates (the ceiling) is purified. An example of local supply ventilation is air curtains commonly used in public places.
Local exhaust specializes in places where pollution accumulates. This practice helps prevent them from spreading throughout the entire room, greatly facilitating the work of the ventilation system.
Interesting! Local ventilation is practically cost-free, unlike general ventilation. But in production workshops, both types are used, since only local ones are not able to simultaneously provide both functions over large areas. General exchange systems uniformly remove polluted air and supply clean air.
What is the type of ventilation in rooms according to design?
There are two types of ventilation design. The monoblock is a single box with sound insulation, being a popular design for installation in homes. There are supply and supply and exhaust types. They do not produce noise, are small in size and easy to install.
A kit is an assembly of various components and additional parts. The advantage is the ability to ventilate both small apartments and entire buildings. The downside is the large size and high requirements for placement of the entire system.
Types of ventilation systems
All types are characterized by a number of parameters, the most important of which is air pumping, which is also the performance of the entire system. Pressure (pressure), power and noise level are also important.
How does one type of ventilation differ from others (a brief comparison of all types)
The local type of ventilation, unlike general ventilation, supplies air to one place and takes polluted air from there. General exchange - applies to the entire room. The supply type is designed only for air supply, while the exhaust type directly affects purification.
Types of air vents for different ventilation systems
Ventilation systems include equipment united by air outlet channels - an indispensable part of ventilation systems. The outlets perform the main function: exchange of air masses. Only three factors influence the efficiency of their work: type, material of manufacture and cross-sectional shape.
Important! You should pay attention to the above characteristics, but the following parameters will be important: dimensions, sealant and noise insulation.
Air vents are classified by type of material: plastic (general use) and metal (for factories). And the section shape: rectangle and circle. In addition, there is an additional criterion of rigidity and flexibility. Flexible air vents are used when branching channels.
