- A related art ventilating system will be described with reference to
FIGS. 1 and 2 . - The related art ventilating system is provided with a
case 10 which is an exterior thereof, atotal heat exchanger 30 for making heat exchange between air being supplied/discharged to/from thecase 10, anair supply fan 41 and anair supply motor 42 for supplying air, and anair discharge fan 51 and anair discharge motor 52 for discharging air. - In one side of the
case 10, there is anoutdoor air inlet 21 for drawing outdoor air (OA), and aroom air outlet 24 for discharging exhaust air (EA). - In the meantime, in the other side of the
case 10, there is aroom air inlet 23 for drawing room air (RA), and anoutdoor air outlet 22 for supplying supply air (SA) to the room. - In the
case 10, there are a passage for guiding the outdoor air drawn through theoutdoor air inlet 21 to theoutdoor air outlet 22 through thetotal heat exchanger 30, and a passage for guiding the room air drawn through theroom air inlet 23 to theroom air outlet 24 through thetotal heat exchanger 30. - Behind the
room air outlet 24, there are theair discharge fan 51 and theair discharge motor 52 for forced discharge of the room air, and behind theoutdoor air outlet 22, there are theair supply fan 41 and theair supply motor 42 for forced supply of the outdoor air. - The operation of the heat exchange type ventilating system will be described.

- Therefore, if the temperature of the supply air rises due to heat from the
air supply motor 42, the total heat exchange efficiency η is reduced. - Along, with this, there has been a problem of difficulty of cutting off noise from the
air supply motor 42 and theair discharge motor 52. - 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.

Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
- Referring to
FIGS. 3 and 4 , a ventilating system in accordance with a preferred embodiment of the present invention will be described. - The ventilating system is includes a
case 100 which is an exterior thereof, atotal heat exchanger 130 for making heat exchange between air being supplied/discharged, anair supply fan 141 and anair discharge fan 151 on one side of thetotal heat exchanger 130, and anair supply motor 142 and anair discharge motor 152 for supplying power to theair supply fan 141 and theair discharge fan 151, respectively. - In one side of the
case 100, there is anoutdoor air inlet 121 in communication with an outside of the room for drawing outdoor air (OA), and aroom air inlet 123 in communication with the room for drawing room air (RA). - In the other side of the
case 100, there is aroom air outlet 124 in communication with an outside of the room for discharging exhaust air (EA) to the outside of room, and anoutdoor air outlet 122 in communication with the room for supplying supply air (SA) to the room. - In the meantime, there are ducts (not shown) connected to the
outdoor air inlet 121, theroom air inlet 123, theoutdoor air outlet 122, and theroom air outlet 124, respectively. - In the
case 100, there are a passage for guiding the outdoor air (OA) drawn through theoutdoor air inlet 121 to theoutdoor air outlet 122 through thetotal heat exchanger 130, and a passage for guiding the room air (RA) drawn through theroom air inlet 123 to theroom air outlet 124 through thetotal heat exchanger 30. - In the
case 100, there is adamper 115 for opening/closing a bypass flow passage formed for air to flow without passing through thetotal heat exchanger 130. - In the
case 100, there are an airsupply fan housing 111 for housing theair supply fan 141 therein, and an airdischarge fan housing 112 for housing theair discharge fan 151 therein. - The air
supply fan housing 111 guides the outdoor air passed through thetotal heat exchanger 130 to theoutdoor air outlet 122, and the airdischarge fan housing 112 guides the room air passed through thetotal heat exchanger 130 to theroom air outlet 124. The airsupply fan housing 111 and the airdischarge fan housing 112 also serve to isolate the room air from the outdoor air. - In this instance, for cross flow of the outdoor air and the room air to make smooth heat exchange, it is preferable that the
outdoor air inlet 121 and theoutdoor air outlet 122, and theroom air inlet 123 and theroom air outlet 124 are arranged at positions diagonal to each other. - With reference to an air flow, the
air discharge fan 151 and theair discharge motor 152 are arranged in front of the room air outlet for forced discharge of the room air. On the other hand, with reference to an air flow, theair supply fan 141 and theair supply motor 142 are arranged in front of theoutdoor air outlet 122 for forced supply of the outdoor air. - The
air supply fan 141 and theair discharge fan 151 are arranged in parallel on one side of thetotal heat exchanger 130 such that theair supply motor 142 and theair discharge motor 152 are arranged on one line. - It is preferable that the
air supply fan 141 and theair discharge fan 151 are radial flow fans each of which receives air in an axial direction and discharged in a radial direction, particularly, sirocco fans. - The
air supply motor 142 and theair discharge motor 152 are arranged in the airdischarge fan housing 112. In detail, theair supply fan 141 and theair supply motor 142 are positioned separated by thepartition 114 which separates the airsupply fan housing 111 and the airdischarge fan housing 112, and theair supply motor 142 and theair discharge motor 152 are arranged in one line along a direction of discharge air flow. - Of course, positions of the
air supply motor 142 and theair discharge motor 152 may be interchanged. - This is for preventing the supply air (SA) from being involved in reduction of temperature efficiency, humidity efficiency, and total heat exchange efficiency caused by the heat generated at the
air supply motor 142 during the outdoor air passes through theair supply fan 141. - In detail, by isolating the
air supply motor 142 from theair supply fan 141, an influence of heat generated at theair supply motor 142 to the supply air is cut off, and along with this, theair supply motor 142 is cooled by the exhaust air passing through theair discharge fan 151. - In this instance, since the total heat exchange efficiency η is fixed by the outdoor air (OA), the room air (RA), and the supply air (SA), but not influenced from the exhaust air (EA), even if a temperature of the exhaust air (EA) rises by the heat generated at the
air supply motor 142 and theair discharge motor 152, the total heat exchange efficiency is not influenced by the heat. - In the air
discharge fan housing 112, there is amotor housing 113 for housing theair supply motor 142, and theair discharge motor 152. - It is preferable that, though the
motor housing 113 surrounds theair supply motor 142 and theair discharge motor 152, themotor housing 113 has an opening on a side of theair discharge fan 151 for introduction of the exhaust air thereto to cool down theair supply motor 142 and theair discharge motor 152. - In addition to this, the surrounding of the
air supply motor 142 and theair discharge motor 152 by themotor housing 113 cuts off noise from theair supply motor 142 and theair discharge motor 152. - The total heat exchange ventilation operation of the ventilation system of the present invention will be described.
- As power is applied to the
air discharge fan 151 at the time the room air is polluted, the room air (RA) is introduced to thecase 100 through theroom air inlet 123, and forcibly discharged to the outside of the room through theroom air outlet 124 by theair discharge fan 151 via thetotal heat exchanger 130. - At the same time with this, as power is applied to the
air supply fan 141, fresh outdoor air (OA) is introduced to thecase 100 through theoutdoor air inlet 121, and supplied to the room through theoutdoor air outlet 122 via thetotal heat exchanger 130. - In this instance, the room air (RA) passing through the
total heat exchanger 130 exchanges heat with the exhaust air (EA), to come to a state similar to a temperature and humidity with the room before being supplied to the room. - The exhaust air is introduced to the
air discharge fan 151, and cools theair supply motor 142 and theair discharge motor 152 as the exhaust air passes through themotor housing 113. - In the meantime, referring to
FIG. 4 , in spring/autumn when there is no great temperature difference between indoor/outdoor, a general ventilation is performed in which no total heat exchange is made between the exhaust (EA) and the outdoor air (OA). - At first, the
damper 115 in thecase 100 is opened, to form a bypass flow line for the exhaust air (room air). Then, the room air (RA) drawn through theroom air inlet 123 is discharged to an outside of the room directly through theair discharge fan 151 via the bypass flow line without passing through thetotal heat exchanger 130. - The fresh outdoor air (OA) being supplied to the room is introduced to the base 100 through the
outdoor air inlet 121, passes through thetotal heat exchanger 130, and supplied to the room through theoutdoor air outlet 122. - In this instance, the exhaust air cools down the
