CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of Korean Application No. P2005-0014457 filed on Feb. 22, 2005, which is hereby incorporated by reference as if fully set forth herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to ventilating systems, and more particularly, to a ventilating system having a heat exchanger for exchanging heat of room air being discharged to an outside of a room with heat of outdoor air supplied to the room. [0004] 2. Discussion of the Related Art [0005] Air in a closed room is gradually polluted as time passes-by due to respiration of people in the room. Therefore, it is required to replace the polluted room air with fresh outdoor air, for which the ventilating system is provided. [0006] In general, the ventilating system is installed in a ceiling in the room. Accordingly, an adequate space is required for installation of the ventilating system, to require a great height between floors of adjacent flats, i.e., a flat height, which impairs spatial efficiency and economy of a building. [0007] In the meantime, recently, for improving a living condition of the room, not only the ventilating system, but also an air cleaner, are started to be used, for cleaning room air. Accordingly, in order to solve such a problem, it is required to design the ventilating system smaller as far as possible. [0008] In the meantime, recently, for improving heat efficiency, the ventilating system is provided with a pre-heat exchanger for making heat of room air being discharged to an outside of a room and heat of outdoor air being supplied to the room to heat exchange. However, the pre-heat exchanger can not but make the case of the ventilating system larger. Therefore, it is required to design a compact ventilating system while employing the pre-heat exchanger. SUMMARY OF THE INVENTION [0009] Accordingly, the present invention is directed to a ventilating system that substantially obviates one or more problems due to limitations and disadvantages of the related art. [0010] An object of the present invention is to provide a ventilating system of which size is small. [0011] Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings. [0012] To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, a ventilating system includes a case having a first flow passage for guiding outdoor air to a room, and a second flow passage for guiding room air to an outside of the room, and a fan unit in the case, the fan unit having a first side for drawing the outdoor air from the first flow passage, a second side for drawing the room air, and a circumferential side for discharging the outdoor air drawn through the first side to the room, and discharging the room air drawn through the second side to an outside of the room. [0013] The first side and the second side are opposite. [0014] The fan unit includes a first fan for drawing the outdoor air through the first side and supplying the outdoor air to the room, and a second fan for drawing the room air through the second side and discharging to an outside of the room. The first fan and the second fan rotate around the same shaft. [0015] The ventilating system further includes a heat exchanger in the case for making the outdoor air supplied to the room, and the room air discharged to the outside of the room to heat exchange. [0016] The ventilating system further includes an air supply scroll in the case, for housing the first fan and guiding the air drawn into the first fan, and an air discharge scroll separated from the air supply scroll, for housing the second fan and guiding the air drawn into the second fan. [0017] The air supply scroll and the air discharge scroll include sides each having an outlet for discharging the air drawn by the first fan or the second fan to the room. [0018] The air supply scroll includes an inlet space formed as one side of the air supply scroll is spaced a predetermined distance away from an inside surface of the case, to make the air supply scroll and the first flow passage in communication. The inlet space includes an upward slope for reducing a flow resistance of the air flowing from the first flow passage to the inlet space. [0019] The air discharge scroll includes a side having an air discharge space in communication with the second flow passage formed therein. [0020] The ventilating system further includes a bypass flow passage for bypassing the heat exchanger such that the outdoor air is supplied to the first fan directly without passing through the heat exchanger. [0021] The ventilating system further includes a first damper for opening/closing the inlet space. Continue reading...
