본 발명은 쾌적한 실내공기를 구현하는 환기장치에 관한 것으로, 특히 실외에서 실내로 유입되는 공기의 질(이산화탄소농도 또는 VOC농도)에 따라 급기량을 자동으로 제어하는 환기장치의 운전제어방법에 관한 것이다.The present invention relates to a ventilation device for implementing comfortable indoor air, and more particularly, to an operation control method of a ventilation device for automatically controlling the air supply amount according to the quality of air (carbon dioxide concentration or VOC concentration) flowing into the room from the outside. .

일반적으로, 집이나 사무실 등의 밀폐된 실내공간에서는 사람의 호흡에 의해 시간이 지나면서 이산화탄소(CO2)의 함량이 증가하게 되어 공기가 탁해지고, 이로 인해 사람의 호흡에 지장을 주게 된다. 따라서 밀폐된 실내공간의 탁해진 공기를 실외로 배출시키고 실외의 쾌적한 공기를 실내로 유입시켜 실내공기를 환기시키는 환기장치가 개발되었으며, 최근에는 환기과정에서 발생하는 열손실을 감소하기 위해 환기장치에 전열교환소자를 채용하고 있다.In general, in a closed indoor space, such as a home or office, the content of carbon dioxide (CO 2 ) is increased over time by the human breathing, the air becomes turbid, thereby disturbing the human breathing. Therefore, a ventilator has been developed that discharges muddy air from an enclosed indoor space to the outside and introduces indoor air into the indoor air to ventilate the indoor air. The total heat exchange element is adopted.

이러한 전열교환소자를 채용한 환기장치로는 대한민국 공개특허공보 2003-0063856호가 있다.Ventilation apparatus employing such a total heat exchange element is disclosed in Republic of Korea Patent Publication No. 2003-0063856.

동 공보에 개시된 환기장치는 실외공기의 흡입유로와 실내공기의 배출유로가 교차하는 지점에 설치되어 실외공기와 실내공기 사이에 열교환이 이루어지도록 하는 전열교환소자와, 급기유로상에 설치된 급기팬과, 배기유로상에 설치된 배기팬을 구비하여, 급기팬과 배기팬이 회전하면 급기유로를 통해 실외공기가 실내로 유입되고, 배기유로를 통해 실내공기가 실외로 배출되며, 배출되는 실내공기와 유입되는 실외공기 사이에 열교환이 일어난다.The ventilation device disclosed in this publication is installed at the point where the intake flow path of the outdoor air and the discharge flow path of the indoor air cross each other, and an electric heat exchange element for heat exchange between the outdoor air and the indoor air, an air supply fan installed on the air supply flow path, And an exhaust fan installed on the exhaust passage, and when the air supply fan and the exhaust fan rotate, outdoor air is introduced into the room through the air supply passage, and indoor air is discharged to the outside through the exhaust passage. Heat exchange occurs between the outdoor air.

이러한 환기장치는 실내의 CO2(이산화탄소)농도를 CO2센서에서 감지하고, 그 감지값에 따라 급기팬과 배기팬의 풍량을 여러 단계(터보, 강, 약)로 제어하여 실내공기 질에 따라 최적의 환기량(급ㆍ배기량)으로 실내공기를 쾌적하게 유지하도록 하였다.This ventilator detects indoor CO 2 (carbon dioxide) concentration in the CO 2 sensor and controls the air volume of the supply and exhaust fans in several stages (turbo, steel, weak) according to the detected value. It is to keep indoor air comfortably with the optimal ventilation (air supply and exhaust).

그러나, 이러한 환기장치는 실내공기의 질만 감지하여 환기량을 설정하고 실 외에서 실내로 공급되는 실외공기의 질에 상관없이 환기를 하기 때문에 실내공기보다 오염된 실외공기가 유입될 경우 실내가 더욱 오염되는 문제가 있었다.However, since the ventilation device detects only the quality of indoor air and sets the ventilation amount, and ventilates regardless of the quality of outdoor air supplied from the outside to the room, the indoor air is more polluted when the contaminated outdoor air is introduced than indoor air. There was.

또한, 상기 제어단계는, 실외공기 오염도가 실내공기 오염도보다 큰 경우 상기 급기팬의 동작을 중지시켜 실외공기의 유입을 차단한다.In addition, in the controlling step, when the outdoor air pollution degree is greater than the indoor air pollution degree, the operation of the air supply fan is stopped to block the inflow of outdoor air.

또한, 상기 제어단계는, 실외공기 오염도가 실내공기 오염도보다 작은 경우 실내공기 오염도에 따라 상기 급기팬의 풍량을 조절하여 급기량을 제어한다.In addition, in the controlling step, when the outdoor air pollution degree is less than the indoor air pollution degree, the air supply amount is controlled by adjusting the air volume of the air supply fan according to the indoor air pollution degree.

또한, 상기 제어단계는, 실외공기 오염도를 미리 정해진 기준값과 비교하여 실외공기 오염도가 기준값 범위이면 상기 급기팬의 풍량을 높여 급기량을 증가시킨다.In addition, in the controlling step, the outdoor air pollution degree is compared with a predetermined reference value, and if the outdoor air pollution degree is within the reference value, the air volume of the air supply fan is increased to increase the air supply amount.

또한, 상기 기준값은 공기의 이산화탄소농도가 400ppm이하이고, VOC농도가 0ppm이하이다.In addition, the reference value is the carbon dioxide concentration of air is 400ppm or less, VOC concentration is 0ppm or less.

그리고, 본 발명은 실외공기를 실내로 유입하기 위한 급기팬을 갖춘 환기장치의 운전방법에 있어서, 실내로 유입되는 실외공기의 오염도를 감지하고, 감지된 실외공기 오염도를 미리 정해진 기준값과 비교하여 상기 실외공기 오염도가 기준값 범위를 벗어나면 상기 급기팬의 동작을 중지시켜 실외공기의 유입을 차단한다.In addition, the present invention provides a method of operating a ventilation device having an air supply fan for introducing outdoor air into a room, the pollution degree of the outdoor air introduced into the room, and the detected outdoor air pollution degree by comparing with the predetermined reference value If the outdoor air pollution degree is outside the reference value range, the operation of the air supply fan is stopped to block the inflow of outdoor air.

이때, 실내와 연통하는 배기유로(16)의 배기 흡입구(16a)와 급기유로(14)의 급기 배출구(14b)에 각각 설치된 실내공기 오염도센서(26)와 실외공기 오염도센 서(28)에서 배기되는 실내공기 오염도(EA)와 급기되는 실외공기 오염도(SA)를 각각 감지하여 제어부(32)에 입력한다(S110).At this time, the exhaust air from the indoor air pollution sensor 26 and the outdoor air pollution sensor 28 installed in the exhaust inlet 16a of the exhaust flow path 16 and the air supply outlet 14b of the air supply passage 14 communicating with the indoor, respectively. The indoor air pollution degree (EA) and the outdoor air pollution degree (SA) to be supplied are respectively sensed and input to the control unit 32 (S110).

따라서, 제어부(32)는 실내공기 오염도센서(26)로부터 입력된 실내공기 오염도(EA)와 실외공기 오염도센서(28)로부터 입력된 실외공기 오염도(SA)를 비교하여 실내공기 오염도(EA)가 실외공기 오염도(SA) 이하인가를 판단한다(S120).Therefore, the controller 32 compares the indoor air pollution degree EA input from the indoor air pollution degree sensor 26 with the outdoor air pollution degree SA input from the outdoor air pollution degree sensor 28 to determine the indoor air pollution degree EA. It is determined whether or not the outdoor air pollution level (SA) (S120).

상기 실내공기 오염도(EA)가 실외공기 오염도(SA) 이하이면 실내로 유입되는 실외공기의 질이 실내공기에 비해 나쁜 상태이므로 이 경우 급기팬(18)을 동작시키면 오히려 실내를 더욱 오염시키게 되므로 제어부(32)는 급기팬(18)을 정지시켜 급기를 중지하고, 실내공기 오염도(EA)에 따라 배기팬(20)의 풍량을 터보, 강, 약으로 제어하여 배기량만 조절한다(S130).If the indoor air pollution degree (EA) is less than the outdoor air pollution degree (SA), the quality of the outdoor air introduced into the room is worse than the indoor air. In this case, if the air supply fan 18 is operated, the indoor air is more polluted. 32 stops the air supply by stopping the air supply fan 18, and controls the air volume of the exhaust fan 20 by turbo, strong, and weak according to the indoor air pollution degree (EA) (S130).

한편, 상기 실내공기 오염도(EA)가 실외공기 오염도(SA) 이하가 아니면 실내로 유입되는 실외공기의 질이 실내공기에 비해 양호한 상태이므로 종래와 동일하게 실내공기 오염도(EA)에 따라 환기량을 설정하게 되는데, 이때 실내공기 오염도(SA)가 제어부(32)에 미리 정해진 정화공기 기준값(SAm) 이하인가를 판단한다.On the other hand, if the indoor air pollution degree (EA) is not less than the outdoor air pollution degree (SA), since the quality of the outdoor air flowing into the room is better than the indoor air, the ventilation amount is set according to the indoor air pollution degree (EA) as in the prior art. In this case, it is determined whether the indoor air pollution degree SA is less than or equal to the predetermined purification air reference value SAm in the control unit 32.

상기 정화공기 기준값(SAm)이란 공기의 이산화탄소농도가 400ppm이하이고, VOC농도가 0ppm이하로 공기의 질이 깨끗한 상태이다.The purge air reference value SAm is a state in which the carbon dioxide concentration of air is 400 ppm or less, and the VOC concentration is 0 ppm or less, and the air quality is clean.

상기 실외공기 오염도(SA)가 정화공기 기준값(SAm) 이하이면 실내로 유입되는 실외공기의 질이 아주 깨끗한 상태이므로 제어부(32)는 급기팬(18)의 풍량을 터보 이상의 최대풍량으로 제어하여 급기량을 최대한으로 높이고, 실내공기 오염도(EA)에 따라 배기팬(20)의 풍량을 터보, 강, 약으로 제어하여 배기량을 조절한 다(S150).If the outdoor air pollution degree SA is less than or equal to the purified air reference value SAm, the quality of the outdoor air introduced into the room is very clean. Therefore, the controller 32 controls the air volume of the air supply fan 18 to the maximum air volume of the turbo or higher air supply. The maximum amount of the air is controlled and the amount of air is controlled by controlling the air volume of the exhaust fan 20 to turbo, strong, and weak according to the indoor air pollution degree (EA) (S150).

따라서, 실내를 보다 빠른 시간에 쾌적하게 함으로서 환기 효과를 극대화할 수 있게 된다.Therefore, it is possible to maximize the ventilation effect by making the room more comfortable at a faster time.

한편, 상기 실외공기 오염도(SA)가 정화공기 기준값(SAm) 이하가 아니면 실내로 유입되는 실외공기의 질이 실내공기에 비해 양호한 상태이나 아주 깨끗한 상태는 아니므로 종래와 동일하게 실내공기 오염도(EA)에 따라 급기팬(18)과 배기팬(20)의 풍량을 제어하여 급기량과 배기량을 동시에 조절한다(S160).On the other hand, if the outdoor air pollution degree (SA) is not less than the standard value of the purified air (SAm), the quality of the outdoor air flowing into the room is not as good or very clean than the indoor air, so the indoor air pollution degree (EA) as before. By controlling the air volume of the air supply fan 18 and the exhaust fan 20 according to the (S160) at the same time to adjust the air supply amount and the exhaust amount (S160).

상기의 설명에서와 같이, 본 발명에 의한 환기장치의 운전제어방법에 의하면, 실외에서 실내로 유입되는 공기의 질이 나쁘면 급기량을 줄이거나 차단을 하여 오염된 실외공기가 실내로 유입되어 실내를 더욱 오염시키는 것을 방지하고, 실내로 유입되는 공기의 질이 깨끗할 경우 급기량을 증가시켜 실내를 보다 빠른 시간에 쾌적하게 함으로서 환기운전에 소비되는 비용을 절감하고 환기의 효과를 극대화할 수 있다는 효과가 있다.As described above, according to the operation control method of the ventilation apparatus according to the present invention, if the quality of the air flowing into the room from the outside is poor, the air volume is reduced or blocked to contaminated outdoor air flows into the room to It is possible to prevent further pollution and to increase the air supply if the quality of the air flowing into the room is clean, making the room more comfortable in a faster time, thereby reducing the cost of ventilation operation and maximizing the effect of ventilation. have.
