[0001] This application claims the benefit of the Korean Application No. P2005-12319 filed on Feb. 15, 2005, which is hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a ventilation system, and more particularly, to a ventilation system, a pressure intensifying apparatus, and a method for controlling the same, in which air volume and external static pressure can be increased. [0004] 2. Discussion of the Related Art [0005] Due to persons' breathes and the like, air in the closed room is gradually polluted with the lapse of time. A ventilation system is used to replace polluted indoor air with fresh outdoor air. [0006] A general ventilation system includes an air supply fan for supplying an outdoor air into a room, an air supply duct for guiding an outdoor air into the room, an air exhaust fan for exhausting an indoor air out of the room, and an air exhaust duct for guiding the indoor air out of the room. [0007] In order to supply air into the room through the duct, the ventilation system must have required air volume and external static pressure. For example, when air is supplied through a circular duct in an about 231-m.sup.2 indoor space by ventilation of 350 CMH, an external static pressure of about 300 Pa is required. At this point, airflow resistance of a duct is an important factor in determining the required air volume and external static pressure. As the indoor space is wide, a length of the duct becomes longer. As the number of the partitioned spaces is increasing, the branches of the duct increase. Consequently, the airflow resistance increases and the required air volume and external static pressure increases. However, it is difficult to increase a capacity of the ventilation system so large as to form sufficient air volume and external static pressure. Thus, the ventilation is not performed smoothly. [0008] Also, the general ventilation system is installed in a ceiling. However, since the ventilation system is designed considering spatial efficiency and economic efficiency, there is a limit in a distance between a bottom of a lower floor and a bottom of an upper floor. Thus, it is difficult to secure sufficient space for installing the ventilation system. Accordingly, in order to solve the problem, the ventilation system needs to be designed to be small-sized. SUMMARY OF THE INVENTION [0009] Accordingly, the present invention is directed to a ventilation system and a pressure intensifying apparatus that substantially obviate one or more problems due to limitations and disadvantages of the related art. [0010] An object of the present invention is to provide a ventilation system, a pressure intensifying apparatus, and a method for controlling the same, in which external static pressure is formed so high that a wide indoor space can be ventilated. [0011] Another object of the present invention is to provide a small-sized ventilation system and a pressure intensifying apparatus, which can be installed in a narrow space. [0012] 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. [0013] To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, there is provided a ventilation system including: a duct branched into at least rooms; a ventilator connected to the duct, for selectively or simultaneously exhausting indoor air and supplying outdoor air; and a pressure intensifying apparatus including: a case in which air supply unit/air exhaust unit connected to the duct are formed; and a fan for intensifying static pressure of air supplied/exhausted through the duct. [0014] The pressure intensifying apparatus may include: at least two air supply units and at least two air exhaust units connected to the duct; a fan disposed inside the case, for supply/exhaust air by rotation thereof; and a drive motor disposed inside the case, for rotating the fan. The pressure intensifying apparatus may further include a damper for opening/closing the air supply unit and the air exhaust unit. [0015] The case may be formed evenly, and the air supply unit and the air exhaust unit may be arranged at a periphery of the case. The case may have top and bottom surfaces formed in a circular shape. Also, the case may be installed in a ceiling. [0016] The air supply unit and the air exhaust unit may be inclined with respect to a rotational radius of the fan. The air supply unit may further include a damper for opening/closing to guide air sucked inside the case in an axial direction of the fan. [0017] The pressure intensifying apparatus may be arranged in a position where the duct is branched. The duct may include an air supply duct and an air discharge duct. The pressure intensifying apparatus may be installed in each of the air supply duct and the air exhaust duct. [0018] The ventilation system may further include a controller for controlling the ventilator and/or the pressure intensifying apparatus according to user's input information. [0019] In another aspect of the present invention, there is provided a pressure intensifying apparatus including: at least two branched ducts; a case divided into an upper space and a lower space; an air supply unit and an air exhaust unit for communicating the upper and lower spaces of the case with the duct; a fan disposed inside the case, for sucking air through the air supply unit and exhausting air through the air exhaust unit, or for sucking air through the air exhaust unit and exhausting air through the air supply unit; and a drive motor, disposed inside the case, for rotating the fan. [0020] The case may be formed evenly, and at least two air supply units and at least two air exhaust units may be arranged at a periphery of the case. [0021] The fan may be configured to suck air in an axial direction and exhaust air in a radial direction. The fan may be a double suction fan having an air supply fan and an air exhaust fan arranged up and down, the air supply fan being configured to suck air toward in an inside of the case through the air supply unit and exhaust the sucked air to the air exhaust unit, the air exhaust fan being configured to suck air through the air exhaust unit and exhaust the sucked air to the air supply unit. [0022] The air supply unit may further include: an air supply damper for opening/closing to guide air sucked inside the case in an axial direction; and an air exhaust damper for opening/closing to guide air exhausted from the fan toward the duct. The air supply damper may include a first air supply damper for guiding air sucked in the air supply unit in an axial direction of the fan, and a second air supply damper for preventing air from being exhausted to the air supply unit when the first air supply damper, and the air exhaust damper includes a first air exhaust damper for guiding air exhausted from the fan to the air exhaust unit, and a second air exhaust damper for preventing air from being sucked into the fan. The air exhaust damper and the air supply damper may alternately open the air supply unit and the air exhaust unit. Continue reading...
