A ventilation system and method

Abstract

The invention provides a ventilation system and method, which are applied to a three-dimensional space with people or animals, including an air intake module, a one-way power exhaust module, a gas detection module and a control module. The air intake module includes an air intake box, a power The air inlet mechanism and the air guide head, the first intercepting screen is arranged in the air inlet box, the power air inlet mechanism includes the air inlet pipe and the second intercepting screen, the first fan, and the porous honeycomb are arranged in the air inlet pipe in sequence according to the air inlet direction. body filter layer, the second fan, the area of ​​the wind passing surface of the first intercepting net plate is greater than the area of ​​the wind passing surface of the second intercepting net plate, the air guide head is movably arranged at the air outlet of the air inlet pipe, and the control module is used It is used to control the start and stop of the first fan, the second fan and the one-way power exhaust module according to the air pressure and the gas concentration of the preset type. Compared with the existing technology, better filtering effect, higher ventilation efficiency, longer service life and better biological safety are achieved.

Description

Technical field [0001] The present invention relates to the field of ventilation technology, particularly, to a ventilation system and method. Background technique [0002] With the increasing emphasis on health, air quality requirements have become more sophisticated. For this purpose, various devices or people to install a system for ventilation so that the air within the building in the building to keep fresh, but there are many disadvantages of the prior art. [0003] In the prior art, some fresh air in the air in the system to the building kept open, but there are many problems, such as poor filtration, resulting in poor air quality. However, although the filter effects or ventilation resistance of air system is large, resulting in poor air flow, fresh air system will not be timely delivery outside fresh air into a building, although the use of some blowing fan, but because the filter material is blocked, inlet air rate remains low, unless the fan is increased in size and / ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, some use the fresh air system to keep the air in the building unblocked, but there are many problems, such as poor filtering effect, resulting in poor air quality

Or although the filtering effect is good, the ventilation resistance of the fresh air system is very large, resulting in poor air flow, and the fresh air system cannot deliver fresh air from the outside to the building in time. Although some fans are used to blow air, due to the blocking of filter materials, The air intake velocity is still low, unless the fan size and / or power is increased, but this will bring other disadvantages such as bulky and difficult to install, loud noise

[0004] In the prior art, the ventilation system with filter structure is easy to block after a period of use, resulting in a decrease in ventilation efficiency

[0005] In the prior art, the filter material of the ventilation system mainly filters solid particles in the air, and it is difficult to effectively filter microorganisms such as bacteria and viruses with small diameters, or solid particles with small diameters.

In some existing technologies, thorough filtration is achieved by setting various types of filter materials, multi-layer filtration and electrochemical methods, but the cost of the system is extremely high, and it is mostly used in hospitals or laboratories, etc., in household occasions, livestock breeding occasions, etc. The environment is difficult to promote and use

[0006] In the prior art, when the straight-through air duct enters the air, if the air volume is too large, it is easy to blow directly to the indoor creatures, which reduces comfort or is not conducive to growth. Some structures such as sampling grilles adjust the direction of the wind, but the structure is complex and Single function

[0007] In the existing technology, in order to save the cost of use, the general ventilation usually has fewer functions, and some ventilation systems have more functions, but they consume energy when they continue to work
