Description

Toxic Gas Automatic Exhaust System Using System Air Conditioner The present invention relates to an automatic toxic gas exhaust system using a system air conditioner, and more specifically, to an automatic toxic gas exhaust system using a system air conditioner that effectively removes toxic gases by using a blower fan of a system air conditioner already installed in a building to suck in toxic gases generated during a fire and discharging the toxic gases to the outside through the building's exhaust duct. This project (result) is the result of the Phase 3 LINC 3.0 Leading University-Industry Cooperation Project, funded by the Ministry of Education and the National Research Foundation of Korea. Generally, when a fire occurs in buildings such as apartments or officetels, people instinctively evacuate to exposed areas like verandas or windows to avoid poisonous gases or flames, and they open the doors or windows. However, due to the nature of toxic gases, they can form a hot air current that increases pressure in the ceiling area through buoyancy caused by heat, and form a thick layer as they spread toward the colder side, which is the direction of lower pressure. As a result, the toxic gases may become stagnant indoors rather than being expelled to the outside by the air entering through the windows. Furthermore, as oxygen is supplied to flames and the fire spreads, the generation of toxic gases can increase rapidly. When a fire occurs, sprinklers can suppress the flames, but there is a problem in that it is not easy to remove toxic gases that have already been generated. Furthermore, current firefighting systems focus solely on extinguishing fires, and most lack equipment for exhausting toxic gases or consist of independent systems such as smoke control. Additionally, since electricity is cut off in the event of a fire, it is difficult to utilize the building's internal electrical facilities. FIG. 1 is a drawing illustrating an automatic exhaust system for toxic gases using a system air conditioner according to one embodiment of the present invention. FIG. 2 is a diagram illustrating the operation of a toxic gas automatic exhaust system using a system air conditioner according to an embodiment of the present invention during normal operation and operation in the event of a fire. The advantages and features of the embodiments of the present invention, and the methods for achieving them, will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments described below but may be implemented in various different forms.
