Description

Air duct manufacturing equipment The present invention relates to an air duct, and more specifically, to a technology for accurately transporting a duct panel to a bending point when bending an air duct, while simultaneously fixing and bending it using an automated method, and to an air duct manufacturing device applicable to the air duct manufacturing industry, the air duct management industry, and industries related to air duct manufacturing devices. Generally, ventilation refers to “an act of intentionally exchanging indoor and outdoor air for the purpose of clear environmental improvement, such as purifying indoor air or improving thermal environmental conditions.” To perform this, it is necessary to install an opening connecting the indoors and outdoors and simultaneously create a pressure difference between the two spaces. When this is done by mechanical force, it is called mechanical ventilation or forced ventilation. Furthermore, regarding the purpose and necessity of ventilation and methods for removing indoor air pollutants known to cause problems such as sick building syndrome, these can be broadly classified into preventing external pollutants from entering the indoor space and rapidly removing pollutants present indoors. The former is divided into methods of eliminating or isolating the source of pollutants and methods of neutralizing them by altering their properties, while the latter is classified into methods of directly removing pollutants using devices such as air purifiers, and methods of diluting or expelling pollutants outdoors through ventilation. These methods are characterized by decreasing effectiveness in pollutant removal in the order listed. While the first method is the most active in the sense, it may be completely ineffective when the substances to be removed—such as carbon dioxide, formaldehyde (HCHO), volatile organic compounds (VOSS), and odors—considering that the primary sources are located indoors, including the human body, human activities, and building interior materials. In the case of carbon dioxide, while it is certainly generated from heat source equipment, the human body can also be a major source. In this case, if the human body is considered a source of contamination, this method may not be able to perform any function. This is because the problem of indoor air pollution in the absence of people does not hold special significance. Contamination caused by pollutants or hazardous chemicals generated from building interior materials or various equipment can also be considered as sources of contamination other than people; in this case, it is possible to remove or isolate pollutants from the indoors to some extent, but in most cases, it is difficult to find such architectural methods. However, in the case of cigarette smoke, it is believed that a certain degree of isolation is possible with the smoker's awareness and cooperation. As such, while the first method is not entirely inapplicable in some cases, it can be considered a measure that is difficult to apply generally. Second, the feasibility of methods that change the nature of the source is slightly higher. However, since it is possible to use physical means such as heating and compression to change the nature of the source and this can only be applied under the assumption that air quality is improved, there are very few methods in actual practice that can neutralize or remove pollutants using only physical means. In most cases, the process of converting a source of pollution into a harmless one often relies on chemical means, and even if the generation of the intended pollutant is prevented, other forms of pollutants may be generated through chemical reactions (secondary pollution), so individual risk assessment of pollutants becomes necessary. Third, removing pollutants that have entered the indoor environment using air purifiers or similar devices can be a significantly more practical method compared to the previous two. However, this is only feasible if the pollutants to be removed are limited to specific substances and their physical and chemical behavioral characteristics are sufficiently known. Therefore, while this method may be practical when the target pollutant is merely airborne dust, it has the disadvantage of being unable to remove all source substances when problematic pollutants—such as formaldehyde (HCHO), volatile organic compounds (VOSS), cigarette smoke, combustion gases, and odors—are complex, including gases and aerosols. Furthermore, if maintenance of the air purifier is insufficient, one must consider the possibility of recurrence of contamination from the purification device if the volume of pollutants exceeds its capacity. Additionally, even with a purification device of appropriate capacity, one must consider the risk of other forms of contamination occurring, such as the proliferation of microorganisms and chemical reactions in the accumulated pollutants.
