Abstract

Disclosed is a compact ventilating system, in which a heat exchange is carried out between the indoor air being exhausted to the outside of a room and the outdoor air being supplied to the inside of the room. The ventilating system includes a case fluid-communicated with the inside of a room and the outside of the room. An air-supply fan unit is secured to the case and introduces the outside air into the inside of the room. An air-exhaust fan unit is secured to the case and exhausts the indoor air to the outside of the room. A pre-heat exchanger is provided inside the case so as to face the air-supply fan unit and the air-exhaust fan unit. The pre-heat exchanger carries out a heat exchange between the indoor air and the outdoor air.

Description

[0001] This application claims priority to Korean Patent Application No. 10-2004-0059267 filed on Jul. 28, 2004, which is hereby incorporated by reference as if fully set forth herein. technical field [0002] The present invention generally relates to a ventilation system. More particularly, the present invention relates to a ventilation system having a preheat exchanger that exchanges heat between indoor air exhausted to the outside of the room and outdoor air supplied to the inside of the room. Background technique [0003] The air in the closed room is gradually polluted as time goes by due to the breathing of people in the room or the like. Therefore, the polluted indoor air needs to be frequently replaced by fresh outdoor air through the ventilation system and the like. One common type of ventilation system is usually mounted on the ceiling inside a room. Therefore, in order to install a conventional ventilation system on the ceiling, it is necessary to provide a suf...
