Ventilation system

Abstract

Ventilating system including a case mounted on a ceiling of a room, an inlet in a bottom surface of the case, and an outlet in a side surface of the case, a partition for dividing the case into an upper space, and a lower space, a fan in the upper space of the case, for drawing room air through the inlet, and discharging through the outlet, a filter assembly at the outlet for purifying air being discharged to the room, a first duct in communication with the upper space of the case for guiding outdoor air into the case, and a second duct in communication with the lower space of the case for guiding the room air introduced into the case to an outside of the room, thereby providing a ventilating system having an air purifying function.

Description

technical field [0001] The present invention relates to a ventilation system, more specifically, to a ventilation system with air purification function. [0002] The present invention claims the priority of Korean application No. P2004-36357 filed on May 21, 2004, the full text of which is hereby incorporated by reference. Background technique [0003] If many people stay in a closed place such as an office or a carriage, the place will be polluted by carbon dioxide or the like that is rapidly produced when people breathe, and the polluted air will have an adverse effect on the human body. [0004] Therefore, the polluted indoor air must be replaced with fresh air from outside, for which a ventilation system is usually used. A ventilation system is installed inside the ceiling to forcibly exhaust indoor air with a fan and bring outdoor air into the room. [0005] Meanwhile, in order to provide a more comfortable indoor environment, currently, in addition to providing a ven...

AI Technical Summary

Problems solved by technology

[0008] Therefore, when there is a large temperature difference between indoors and outdoors, for example in summer or winter, the introduction of outdoor air will require additional cooling or heating of the indoors, which unnecessarily increases fuel costs

[0009] Second, existing ventilation systems that have neither dust collection function nor deodorization function are limited in providing a comfortable indoor environment

[0010] However, air purifiers not only need to occupy a large installation space, but also often do not work because they are easy to forget to use

In addition, the ventilation system and the air cleaner operate independently, so it is difficult to adapt to changes in the operating status, and there is a problem of increasing the cost of the product
