FIG. 1 illustrates a diagram schematically showing a ventilating system in accordance with a first embodiment of the present invention mounted in a ceiling of a room,FIG. 2 illustrates a top perspective view showing an inside structure of a cabinet provided at the ventilating system in accordance with the present invention operating in an air purifying mode,FIG. 3 illustrates a bottom perspective view showing the cabinet provided in the ventilating system in accordance with the present invention operating in the air purifying mode,FIG. 4 illustrates a top perspective view showing an inside structure of the cabinet provided in the ventilating system in accordance with the present invention operating in a ventilation mode, andFIG. 5 illustrates a bottom perspective view showing the cabinet provided in the ventilating system in accordance with the present invention operating in the ventilation mode. - Referring to
FIG. 1 toFIG. 5 , the ventilating system in accordance with the present invention includes acabinet 100 mounted in the room, asupply duct 200 coupled with the cabinet, for guiding outdoor air to the cabinet, and anexhaust duct 300 coupled with thecabinet 100, for guiding the room air to an outside thereof. - In this case, the
cabinet 100 is mounted in or attached to aceiling 10 such that one surface of thecabinet 100 is exposed. Thecabinet 100 may of course be mounted in or attached to awall 20. - The
supply duct 200 and theexhaust duct 300 are elongated in a same direction and passed through an outer wall of a building exposed to outdoor air. - For easily coupling the
supply duct 200 and theexhaust duct 300 with thecabinet 100, it is desirable that ends of thesupply duct 200 and theexhaust duct 300 are respectively coupled with a same side of thecabinet 100. - When the
supply duct 200 and theexhaust duct 300 are coupled respectively with different surfaces of thecabinet 100, at least one of thesupply duct 200 and theexhaust duct 300 is bent or cut so as to be coupled with thecabinet 100. Therefore, a mounting operation of the ventilating system is complex, airflow resistance is increased, and the duct is elongated in length. - Accordingly, if the
cabinet 100 is mounted in the ceiling such that a first side of thecabinet 100 coupled with thesupply duct 200 and theexhaust duct 300 faces the ends of thesupply duct 200 and theexhaust duct 300 when thesupply duct 200 and theexhaust duct 300 are mounted in a ceiling so as to be coupled with a same surface of thecabinet 100 during a building construction, a coupling operation that couples thecabinet 100 with thesupply duct 200 and theexhaust duct 300 is simply carried out. - Although the
cabinet 100 provided at the ventilating system may be formed in various forms, thecabinet 100 formed in a hexahedron, more particularly, in a rectangular parallelepiped having a thin thickness is introduced in this embodiment. - The
cabinet 100 is configured to draw in room air and discharge air into a room at the same time. Thecabinet 100 includes afirst inlet 110 for drawing in room air, asecond inlet 120 coupled with thesupply duct 200, at least one first outlet for discharging air into the room, and a second outlet coupled with theexhaust duct 300. - The
second inlet 120 and thesecond outlet 140 are formed on a same surface of thecabinet 100, and coupled respectively with thesupply duct 200 and theexhaust duct 300. - In this case, the
supply duct 200 and theexhaust duct 300 are inserted respectively into thesecond outlet 140 and thesecond inlet 120 so as to be coupled respectively thereto. Accordingly, thecabinet 100 is easily coupled respectively with thedischarge duct 300 and thesupply duct 200. - Due to the structure, when the room air drawn into the
first inlet 110 is discharged through theexhaust duct 300 to an outside, and outdoor air flowed in by thesupply duct 200 is discharged into the room through thefirst outlet 130, the ventilating system with the cabinet performs only a ventilating function. - In case that a
filter 160 that purifies air discharged through thefirst outlet 130 into the room is provided in thecabinet 100, the ventilating system purifies outdoor air and supplies the purified air into the room. - In case of the ventilating system ventilating the room and supplying the purified air into the room at the same time, a filter for purifying air may be provided in the
supply duct 200. - It is however desirable that the ventilating system in accordance with the present invention performs not only a function of ventilating room air but also a function of purifying the room air.
- A first embodiment of the
cabinet 100 provided in the combination purifier and ventilator will be described with reference toFIG. 2 toFIG. 5 . Referring toFIG. 2 toFIG. 5 , afan 150 for forcing air to flow is provided in thecabinet 100, and afilter 160 for purifying air discharged to thefirst outlet 130. Aseparate fan 310 for forcing air to flow is provided in theexhaust duct 300 so as to discharge the room air to the outside. - The
cabinet 100 further includes athird inlet 170 for drawing in the room air, that is, communicating with theexhaust duct 300, the room air discharged through theexhaust duct 300 to the outside. - Each structural element of the
cabinet 100 will be described in more detail as follows. Thefirst inlet 110 is formed on a lower surface of thecabinet 100, that is, in the middle of a surface facing the room, and thefirst outlet 130 and thethird inlet 170 are formed on a lower edge of thecabinet 100. -
- A
suction louver 111 is provided at thefirst inlet 110 for opening/closing thefirst inlet 110, and coupled to a motor, particularly, to a stepping motor, and at least one wind-direction controlling louver 131 is provided at thefirst outlet 130, for controlling direction of air discharged therefrom. - The at least one wind-
direction controlling louver 131 is fixed at a predetermined angle or provided to be controlled manually, and preferably, to be rotated by the motor. In other words, thelouver 131 is remained or automatically swung at a predetermined angle during an operation of the ventilating system, and thefirst outlet 130 is closed for preventing impurities from being entered therein during stoppage of the ventilating system. - The
third inlet 170 is formed at an edge of a side coupled with thesupply duct 200 and theexhaust duct 300, among edges of a lower surface of thecabinet 100, particularly, at a part lying at right angles to thesecond outlet 140 coupled with theexhaust duct 300. - Meanwhile, the
filter 160 is provided at an upper part of thefirst inlet 110. At an upper part of the filter, thefan 150 is provided for generating a suction force so as to draw in air through thefirst inlet 110 and thesecond inlet 120. - In this case, the
filter 160 removes impurities contained in the room air flowed through thefirst inlet 110 and in the outdoor air flowed through thesecond inlet 120. A separate filter assembly may further be provided at thecabinet 100 for removing minute impurities or bad smell. - A predetermined space is formed between the
filter 160 and thefirst inlet 110. The outdoor air drawn in through thesecond inlet 120 coupled with thesupply duct 200 and the room air drawn in through thefirst inlet 110 are flowed into the space formed between the first inlet and 110 thefilter 160, and then moved upward by the operation of thefan 150 so as to be purified by thefilter 160. - In the mean time, the
fan 150 includes a motor, and acentrifugal fan 151 rotated by the motor. At the third edge of the fan and thefilter 160, i.e., at an upper part of thefirst outlet 130, a passage is formed for guiding air to thefirst outlet 130, the air radially discharged from thefan 150. - In addition, it is desirable that the ventilating system further includes an air cutoff for selectively cutting off outdoor air flowed into
cabinet 100 through thesupply duct 200 such that the system is operated in an air purifying mode. - The air cutoff includes a
damper 121 provided at thesecond inlet 120, thedamper 121 rotated by a motor for dampers. Thedamper 121 may of course be provided at thesupply duct 200, and a separate damper (not shown) may be provided at theexhaust duct 300 and either of thesecond outlet 140 and the third outlet. - In the mean time, it is desirable that the
supply duct 200 and theexhaust duct 300 are provided in a direction perpendicular to the thickness direction of the ceiling, i.e., provided horizontally to be parallel to each other, such that the ceiling, wherein the ventilating system is mounted, is prevented from being increased in thickness. It is because the thickness of the ceiling is increased for mounting thesupply duct 200 and theexhaust duct 300 therein when thesupply duct 200 and theexhaust duct 300 are provided in the thickness direction of the ceiling. - When the
cabinet 100 is mounted in or attached to a wall, it is desirable that thesupply duct 200 and theexhaust duct 300 are provided to be parallel to each other in a direction perpendicular to the thickness direction of the wall. - It is also desirable that the
second inlet 120 and thesecond outlet 140 are coupled respectively to a lower portion on the first side of thecabinet 100, the lower portion being coupled with thesupply duct 200 and theexhaust duct 300. Accordingly, the thickness of thecabinet 100 is decreased. - The ventilating system in accordance with the present invention structured as above-mentioned is operated as follows. First, a case of operating the ventilating system in a ventilation mode will be described. When a power source is supplied to the ventilating system, the
first inlet 110 is closed by thesuction louver 111, thesecond inlet 120 is opened by thedamper 121, and afan 150 of thecabinet 100 and afan 310 of theexhaust duct 300 are operated. - Accordingly, outdoor air is drawn into the
cabinet 100 through thesupply duct 200 and purified, passing through thefilter 160. The air purified at the filter is radially discharged by thecentrifugal fan 151 of the fan, and then discharged into the room through thefirst outlet 130. - In this instance, the wind-
direction controlling louver 131 supplies fresh air into the room by controlling the direction of air discharged into the room. Meanwhile, the polluted room air drawn into thethird inlet 170 by thefan 310 of the exhaust duct is discharged to the outside thereof through thesecond outlet 140 and theexhaust duct 300. - Through the process, the ventilation is performed for ventilating the room. Next, the process of operating the ventilating system in the air-purifying mode without ventilating the room air will be described.
- When the power supply is supplied to the ventilating system, the
suction louver 111 opens thefirst inlet 110, and thedamper 121 closes thesecond inlet 120. Although thefan 150 of the cabinet is also operated, thefan 310 of the exhaust duct is not operated. By the operation of thefan 150 of the cabinet, the polluted room air is drawn into thecabinet 100 through thefirst inlet 110 and the air drawn into thecabinet 100 is purified, passing through thefilter 160. - The air purified at the filter is then radially discharged via the
centrifugal fan 151 of the fan and discharged into the room through thefirst inlet 130. In this instance, the wind-direction controlling louver 131 controls the direction of air discharged into the room. Through the process, the air purification is performed for purifying the room air. - In the mean time, the
suction louver 111 opens thefirst inlet 110 and thedamper 121 opens thesecond inlet 120. Ventilation and purification of the room air are performed at the same time when thefan 150 of the cabinet and thefan 310 of the exhaust duct are both operated. - Referring to
FIG. 6 toFIG. 8 , a second embodiment of the ventilating system in accordance with the present invention will be described.FIG. 6 illustrates a diagram schematically showing a ventilating system in accordance with a second embodiment of the present invention mounted in a ceiling of a room,FIG. 7 illustrates a diagram schematically showing the ventilating system in accordance with the second embodiment of the present invention attached to a wall, andFIG. 8 illustrates a diagram schematically showing the ventilating system in accordance with the second embodiment of the present invention attached to the wall. - The second embodiment of the ventilation system in accordance with the present invention further includes a
regeneration heat exchanger 400 for exchanging heat between the outdoor air guided by thesupply duct 200 and room air guided by theexhaust duct 300, such that a part of cool air of the room air is drawn back in summer and a part of warm air of the room air is drawn back by exchanging heat between the outdoor air guided by thesupply duct 200 and the room air guided by theexhaust duct 300 at theregeneration heat exchanger 400. - The
regeneration heat exchanger 400 includes afirst flow tube 410 having a plurality of passages through which air flowing along thesupply duct 200 passes, and asecond flow tube 420 having a plurality of passages through which room air flowing along theexhaust duct 300 passes. - The
first flow tube 410 and thesecond flow tube 420 are adjoined each other, and a bordering member adjoined to each other is made of a material having excellent heat conductivity. It is desirable that asupplementary fan 210 is provided at thesupply duct 200 for improving a suction force of the outdoor air. - The
cabinet 100 provided in the ventilation system in accordance with the second embodiment of the present invention, which is structured as above-mentioned, can be provided in various ways. For example, thecabinet 100 is mounted in aceiling 10 as illustrate inFIG. 6 or in awall 20 as illustrated inFIG. 7 , or attached to thewall 20 as illustrated inFIG. 8 . - The
cabinet 100 can of course be attached to a corner of theceiling 10. In this case, thesupply duct 200 and theexhaust duct 300 cannot be seen. It is also understood that thecabinet 100 can be mounted in a half-mounted form wherein a half portion of thecabinet 100 is mounted in theceiling 10 or in thewall 20. - Other structural elements except the regeneration heat exchanger are the same as those in the foregoing ventilating system in accordance with the first embodiment of the present invention, and identical parts will be given the same reference numbers will be used for the same elements, and repetitive description of which will be omitted.
- First, according to the ventilating system in accordance with the present invention, since a supply duct and an exhaust duct are connected to a same side of the cabinet, duct during construction of a building, it is easy to mount the supply duct and the exhaust and to connect the supply duct and the exhaust duct with the cabinet.
- Second, according to the ventilating system in accordance with the present invention, the supply duct and the exhaust duct are mounted in to be parallel to each other in a direction perpendicular to a thickness direction of a ceiling or a wall, thus a space for mounting the ventilating system is minimized.
- Third, according to the ventilating system in accordance with the present invention, the thickness of the ceiling or the wall is prevented from being increased owing to the installation of the ventilating system, and story height is prevented from being increased. Therefore, construction expenditure is reduced.
- Fourth, the ventilating system in accordance with the present invention is operated not only in a ventilation mode but also in an air-purifying mode. Therefore, room atmosphere is maintained pleasant.
