Comfort in our life is largely ensured thanks to ventilation systems. Clean air and an optimal microclimate have become part 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, a private house, in industrial premises
Ventilation system - complex equipment for the regulation of indoor air exchange. The system also affects the microclimate due to technical means. Modern ventilation is able to clean the air flow, moisturize it, heat or cool. Ensuring air circulation in an apartment, a private house and production shops varies greatly.
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 rates result in headache at best, and constant oxygen deficiency significantly affects well-being.
Air in living rooms needs to be updated at least once per hour. In other words, the refresh rate per hour is 1. This is enough for a comfortable stay in an apartment or private house. But even so, in kitchens, the multiplicity increases to 3-5 times.
Air circulation in a closed workshop or in warehouses has a large multiplicity. In factories, other sources of pollution usually exist, which means that cleaning should be done more often. For example, in public smoking rooms, which are an integral part of large industrial 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 shops such an opportunity is practically absent.
Methods for determining the extensive classification of ventilation systems
Ventilation can be characterized by 4 types: by the method of air circulation, purpose, structural structure and working area. Each of the types has advantages and disadvantages.
Types of ventilation by the method of forming air flows
Air exchange occurs due to natural draft, depending on two factors:
- difference in temperatures outside and inside;
- the difference in pressure between the room and the hood.
Weather conditions, such as wind, matter. Such systems do not require additional equipment, spend little electricity and are easy to operate.
Artificial ventilation, otherwise called mechanical, ventilation works on the basis of equipment and a set of additional devices, due to which air exchange covers large rooms. The operation of mechanical systems requires huge amounts of electricity. They are completely autonomous and not affected by nature.
What are the intended ventilation
Allocate supply and exhaust ventilation. The supply system provides an influx of fresh air, the exhaust system - the outflow of treated air. Systems are used together. They can also be classified as local - for a specific site, and general - for large workshops.
Types of ventilation systems by field of operation
Types of local ventilation - supply and exhaust systems. When using this type of air is supplied to the selected area, and only the place of carbon dioxide accumulation (ceiling) is subjected to purification. An example of local ventilation is air curtains commonly used in public places.
Local exhaust specializes in pollution accumulation sites. This practice allows you to prevent their spread to the entire room, greatly facilitating the work for the ventilation system.
Interesting! Local ventilation practically does not require costs, unlike general exchange. But both types are used in production workshops, since only local ones are not able to simultaneously provide both functions in large areas. General exchange systems evenly remove contaminated air and supply clean air.
What is the ventilation in the rooms by design
The ventilation design is of two types. Monoblock is a single box with sound insulation, being a popular design for installation in homes. The supply and exhaust types are different. They do not produce noise, are small in size and easy to install.
Stacking is an assembly of various components and additional parts. The advantage is the ability to ventilate both small apartments and entire buildings. The downside can be considered large sizes and high requirements for the 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 the performance of the entire system. Pressure (pressure), power and noise level are also important.
How one type of ventilation differs from others (a brief comparison of all types)
The local type of ventilation, in contrast to the general exchange, delivers air to one place, and from there it takes in polluted air. General exchange - affects the entire room. The supply type is designed only for air supply, while the exhaust type directly affects cleaning.
Types of air vents for different ventilation units
Ventilation systems include equipment combined by channels for air outlet - an indispensable part of ventilation systems. Branches perform the main function: the exchange of air masses. Only three factors affect their performance: type, material of manufacture and sectional shape.
Important! Attention should be paid to the above characteristics, however, the parameters: dimensions, sealant and noise insulation will be important.
Ducts are classified by type of material: plastic (general use) and metal (for factories). And sectional shape: rectangle and circle. In addition, there is an additional criterion for rigidity and flexibility. Flexible air vents are used for branching channels.
