상기 제어부(70)는 사용자의 요청에 따라 전열교환운전을 시작하도록 신호를 출력하고(S1), 상기 실외온도 감지센서(50)와 실내온도 감지센서(51)가 감지한 온도를 입력받으며(S1), 상기 감지된 실내온도와 실외온도에 따라 히터(40)와 급기팬(20), 배기팬(21)이 가동되며, 급기댐퍼(60)와 배기댐퍼(61), 가변댐퍼(62)가 개폐되도록 한다.The controller 70 outputs a signal to start the total heat exchange operation according to a user's request (S1), receives the temperature detected by the outdoor temperature sensor 50 and the indoor temperature sensor 51 (S1). ), The heater 40, the air supply fan 20, and the exhaust fan 21 operate according to the detected indoor and outdoor temperatures, and the air supply damper 60, the exhaust damper 61, and the variable damper 62 are operated. Open and close.

도 4 내지 도 5를 참조하면 상기 제어부(70)는 사용자의 요청에 따라 전열교환운전을 시작한다(S1).4 to 5, the control unit 70 starts the total heat exchange operation at the request of the user (S1).

또한 상기 제어부(70)는 상기 급기팬(20)과 배기팬(21)이 가동되도록 급기팬모터구동부(22)와 배기팬모터구동부(23)에 신호를 보내고, 이로 인해 급기팬모터(24)와 배기팬모터(25)가 구동되며, 상기 급기팬(20)과 배기팬(21)이 회전하면서 실외공기를 흡입하여 급기유로(P1)를 통해 실내에 공급하고 실내공기는 배기유로(P2)를 통해 실외로 배출하게 된다(S1).In addition, the control unit 70 sends a signal to the air supply fan motor driver 22 and the exhaust fan motor driver 23 so that the air supply fan 20 and the exhaust fan 21 operate, and thus the air supply fan motor 24. And the exhaust fan motor 25 is driven, and the air supply fan 20 and the exhaust fan 21 rotate to suck the outdoor air and supply the indoor air through the air supply passage P1, and the indoor air is the exhaust passage P2. It is discharged to the outdoor through (S1).

그리고 상기 제어부(70)는 상기 실외온도 감지센서(50)와 실내온도 감지센서(51)로부터 감지된 실내온도와 실외온도를 입력받는다(S1).The controller 70 receives the indoor temperature and the outdoor temperature detected by the outdoor temperature sensor 50 and the indoor temperature sensor 51 (S1).

상기 입력받은 실내온도와 실외온도를 통해 상기 제어부(70)는 최근 30분 동안 실내온도가 15℃ 이상 29℃ 미만에 해당하는지 판별한다(S2).The controller 70 determines whether the indoor temperature corresponds to 15 ° C. or more and less than 29 ° C. during the last 30 minutes (S2).

또한 상기 제어부(70)는 최근 30분 동안 실내온도와 실외온도의 차가 10℃를 초과하는지 판별한다.In addition, the controller 70 determines whether the difference between the indoor temperature and the outdoor temperature exceeds 10 ° C in the last 30 minutes.

상기 15℃ 이상 29℃ 미만의 실내온도는 통상의 실내온도이고 실내온도와 실외온도의 차가 클수록 전열교환소자(30)는 습기를 많이 포함하게 된다.The indoor temperature of 15 ° C. or more and less than 29 ° C. is a normal indoor temperature, and the greater the difference between the indoor temperature and the outdoor temperature, the more the heat exchange element 30 contains moisture.

최근 30분 동안의 실내온도가 15℃ 이상 29℃ 미만에 해당되거나 실내온도와 실외온도의 차가 10℃를 초과한 상태로 1시간 이상 가동하면 상기 제어부는 상기 전열교환소자(30)가 습기를 포함한다고 판단하고 전열교환운전의 누적가동시간이 1시간 이상인지 판별한다(S3).If the indoor temperature for the last 30 minutes is more than 15 ℃ less than 29 ℃ or the difference between the indoor temperature and the outdoor temperature exceeds 10 ℃ for more than one hour the control unit the heat exchange element 30 contains moisture It is determined that the cumulative operating time of the total heat exchange operation is 1 hour or more (S3).

따라서 상기 제어부(70)는 상기 전열교환운전의 누적가동시간이 1시간 미만이면 사용자의 전열교환운전정지요청을 받았는지 판별한다(S4).Therefore, if the cumulative operating time of the total heat exchange operation is less than 1 hour, the controller 70 determines whether a request for stopping the heat exchange operation of the user has been received (S4).

반면에 상기 제어부(70)는 최근 30분 동안의 실내온도가 15℃ 이상 29℃ 미만에 해당하지 않거나 실내온도와 실외온도의 차가 10℃를 이하 또는 사용자의 전열교환운전정지요청을 받지 않았다고 판별되면 급기댐퍼구동부(63)와 배기댐퍼구동부(64)에 신호를 보내 급기댐퍼모터(66)와 배기댐퍼모터(67)를 구동시켜 상기 급기댐퍼(60)와 배기댐퍼(61)를 열며 가변댐퍼구동부(65)에 신호를 보내 가변댐퍼모터(68)를 구동시켜 가변댐퍼(63)를 닫도록 하여 통상의 환기를 한다.On the other hand, if the control unit 70 determines that the indoor temperature for the last 30 minutes does not correspond to more than 15 ℃ and less than 29 ℃ or the difference between the indoor temperature and the outdoor temperature is less than 10 ℃ or did not receive the user's request for electrothermal exchange operation Sends a signal to the air supply damper driver 63 and the exhaust damper driver 64 to drive the air supply damper motor 66 and the exhaust damper motor 67 to open the air supply damper 60 and the exhaust damper 61 to open the variable damper driver. A signal is sent to 65 to drive the variable damper motor 68 to close the variable damper 63 for normal ventilation.

본 발명에 따른 환기장치의 전열교환운전의 누적가동시간이 1시간 이상으로 판별되거나 사용자의 전열교환운전정지요청을 받은 것으로 판별되면 상기 제어부(70)는 상기 전열교환운전을 정지시키도록 신호를 보낸다(S5).If the cumulative operating time of the total heat exchange operation of the ventilator according to the present invention is determined to be 1 hour or more or received from the user's request for the total heat exchange operation, the control unit 70 sends a signal to stop the heat exchange operation. (S5).

그 후 상기 제어부(70)는 실외온도가 1℃ 미만이라고 판단되면 실외온도로 인해 전열교환소자(30)가 포함한 수분이 결빙될 염려가 있으므로 히터(40)를 가동하도록 히터구동부(41)에 신호를 보낸다(S6).Thereafter, when the outdoor temperature is determined to be less than 1 ° C., the controller 70 signals the heater driver 41 to operate the heater 40 because the outdoor temperature may freeze moisture contained in the heat exchange element 30. Send (S6).

또한 상기 제어부(70)는 실외온도가 8℃ 미만일 경우에는 겨울이라고 판단하여 실외온도가 8℃ 이상인지 판별하고(S7) 결로방지운전을 시행(S8, S9)한다.In addition, the controller 70 determines that the outdoor temperature is winter when the outdoor temperature is less than 8 ℃ (S7) and performs the dew condensation prevention operation (S8, S9).

겨울에는 실외공기가 봄 또는 가을보다 오히려 습도가 낮아 건조하므로 실외온도가 8℃이상이라고 판별되면 결로방지운전을 30분간 시행(S8)하도록 하고, 실외온도가 8℃미만이라고 판별되면 결로방지운전을 20분간 시행(S9)하는 것이 바람직하다.In winter, the outdoor air is dried with lower humidity than spring or autumn, so if it is determined that the outdoor temperature is higher than 8 ℃, run the condensation prevention operation for 30 minutes (S8) .If it is determined that the outdoor temperature is lower than 8 ℃, prevent the dew condensation operation. It is preferable to perform (S9) for 20 minutes.

상기 제어부(70)의 결로방지운전은 상기 급기댐퍼구동부(63)와 배기댐퍼구동부(64)에 신호를 보내 상기 급기댐퍼(60)와 배기댐퍼(61)를 닫으며, 상기 가변댐퍼구동부(65)에 신호를 보내 가변댐퍼(62)를 열어서 실외공기가 실내로 유입되지 않고 바로 배기유로를 통해 상기 전열교환소자(30)가 포함한 습기와 함께 실외로 배출되도록 유로를 변경하는 것이 바람직하다.Condensation prevention operation of the control unit 70 sends a signal to the air supply damper driver 63 and the exhaust damper driver 64 to close the air supply damper 60 and the exhaust damper 61, and the variable damper driver 65 It is preferable to change the flow path so that the variable damper 62 is opened so that outdoor air does not flow into the room, but is discharged to the outside with moisture included in the heat exchange element 30 through the exhaust flow path.

따라서 상기 히터(40)가 상기 전열교환소자(30) 또는 급기되는 실외공기를 가열하여 수분을 증발시키고, 급기댐퍼(60)와 배기댐퍼(61)는 닫혀서 상기 급기되는 실외공기가 실내로 유입되지 않은채 가변댐퍼(62)를 통해 실외로 배출됨으로써 상기 전열교환소자(30)는 습기를 머금지 않아 수명이 증대되고 열교환효율이 높아지며 환기장치 내부 및 실내 오염의 위험이 크게 줄어든다.Therefore, the heater 40 heats the electrothermal exchange element 30 or the outdoor air to be supplied to evaporate moisture, and the air supply damper 60 and the exhaust damper 61 are closed so that the outdoor air to be supplied is not introduced into the room. By being discharged to the outside through the variable damper 62, the heat exchange element 30 does not retain moisture, thereby increasing its lifespan, increasing heat exchange efficiency, and greatly reducing the risk of internal and indoor pollution of the ventilator.

상기 제어부(70)는 결로방지운전을 마친 후(S8, S9) 급기팬(20)과 배기팬(30)을 가동하고, 전열교환운전을 시작하며 실내온도 및 실외온도를 입력받아(S1) 상기 과정들을 반복하여 수행한다.The control unit 70 operates the air supply fan 20 and the exhaust fan 30 after completing the condensation prevention operation (S8 and S9), starts the heat exchange operation, and receives the indoor temperature and the outdoor temperature (S1). Repeat the process.

(S1).

최근 30분동안의 실내온도가 15℃ 이상 29℃ 미만에 포함되면서 실내온도와 실외온도차가 10℃를 초과하고(S2), 전열교환운전이 1시간 이상 누적가동되었으며(S3), 사용자가 상기 전열교환운전을 정지요청을 하였다면(S4), 상기 제어부(70)는 상기 전열교환운전을 정지(S5)하도록 제어한다.The temperature difference between the room temperature and the outdoor temperature is more than 15 ° C and less than 29 ° C in the last 30 minutes, the difference between the room temperature and the outdoor temperature exceeds 10 ° C (S2), and the total heat exchange operation is accumulated for more than 1 hour (S3). If the replacement operation is requested to stop (S4), the control unit 70 controls to stop the total heat exchange operation (S5).

만약 최근 30분동안의 실내온도가 15℃ 이상 29℃ 미만에 포함되지 않으면서 실내온도와 실외온도차가 10℃이하이거나, 전열교환운전이 1시간 이상 누적가동되었거나, 사용자가 상기 전열교환운전을 정지요청을 하지 않았다면, 상기 제어부(70)는 급기댐퍼(60)와 배기댐퍼(61)를 열고 가변댐퍼(62)를 닫아 공기유로를 각각 유지하여 환기장치가 일반적인 운전(S10)을 하도록 한다.If the indoor temperature and outdoor temperature difference are not included within 15 ℃ or more and less than 29 ℃ for the last 30 minutes, the indoor temperature and outdoor temperature difference is less than 10 ℃, or the total heat exchange operation is accumulated for more than 1 hour, or the user stops the heat exchange operation. If the request is not made, the control unit 70 opens the air supply damper 60 and the exhaust damper 61 and closes the variable damper 62 to maintain the air flow paths, respectively, so that the ventilation apparatus performs the normal operation (S10).

또한 실외온도가 1℃ 미만이면 상기 전열교환소자(30)에 포함된 수분이 결빙될 염려가 있으므로 상기 제어부(70)는 히터구동부(41)에 신호를 보내 히터(40)를 가동시켜 상기 전열교환소자(30)의 훼손 및 오염을 방지(S6)하도록 제어한다.In addition, when the outdoor temperature is less than 1 ° C., moisture contained in the heat exchange element 30 may freeze, so the controller 70 sends a signal to the heater driver 41 to operate the heater 40 to exchange the heat. Control to prevent damage and contamination of the device 30 (S6).

그리고 겨울철이 타 계절보다 습도가 상대적으로 낮으므로 상기 제어부(70)는 실외온도가 8℃ 이상으로 감지되면 30분간 결로방지운전을 시행(S8)하고 실외온도가 8℃ 미만으로 감지(S7)되면 겨울철이라고 판단하여 20분간 결로방지운전을 시행(S9)한다.And since the humidity in winter is relatively lower than other seasons, the control unit 70 performs an anti-condensation operation for 30 minutes when the outdoor temperature is detected as more than 8 ℃ (S8) and when the outdoor temperature is detected as less than 8 ℃ (S7) It is determined that the winter season 20 minutes condensation prevention operation (S9).

상기 결로방지운전은 공기유로를 바꾸어 상기 전열교환소자(30) 내부의 수분을 실외로 배출하기 위한 것으로, 상기 제어부(70)는 급기댐퍼구동부(63)와 배기댐퍼구동부(64)에 신호를 보내 급기댐퍼모터(67)와 배기댐퍼모터(68)를 구동시켜 급기댐퍼(60)와 배기댐퍼(61)를 닫고, 가변댐퍼구동부(65)에 신호를 보내 가변댐퍼모터(68)를 구동시켜 가변댐퍼(62)를 열며, 따라서 급기팬(20)을 통해 급기유로(P1)로 들어온 실외공기는 실내로 유입되지 못하고 열려있는 가변댐퍼(62)를 통하여 배기유로(P2)로 이동하고 배기팬(21)에 의해 상기 전열교환소자(30) 내부의 수분과 함께 실외로 배출된다.The dew condensation prevention operation is to discharge the water inside the heat exchange element 30 by changing the air flow path to the outside, and the control unit 70 sends a signal to the air supply damper driver 63 and the exhaust damper driver 64. The air supply damper motor 67 and the exhaust damper motor 68 are driven to close the air supply damper 60 and the exhaust damper 61, and a signal is sent to the variable damper driver 65 to drive the variable damper motor 68.
