CONSTITUTION: An apparatus(300) for detecting the defects of fans and filters in a heat recovery ventilator comprises a fan rotation-number detector(310), a fan motor current detector(320), a controller(330), and an alarming unit(340). The fan rotation-number detector detects each rotation number of the air exhaust fan and the air supply fan of the heat recovery ventilator. The fan motor current detector detects the current of the fan motor driving the air exhaust fan and the air supply fan. The controller determines the normal range of the fan motor current which is measured based on the rotation number of a specific one of the air supply fan and the air exhaust fan and outputs an alarming signal by determining a filter defect or a fan defect by comparing, the current of the fan motor corresponding to the rotation number of a specific fan measured when the air exhaust fan and the air supply fan are driven, with the normal range. If the alarming signal is input, the alarming unit alarms the filter defect or the fan defect.

Description

폐열회수형 환기장치의 팬 및 필터 결함 감지 장치 및 방법{Apparatus and method for perceiving defects of fans and filters in a heat recovery ventilator}Apparatus and method for perceiving defects of fans and filters in a heat recovery ventilator}

본 발명은 환기장치 결함 감지 기술에 관한 것이며, 더욱 상세히는 폐열회수형 환기장치의 팬 및 필터 결함 감지 장치 및 방법에 관한 것이다.The present invention relates to a ventilator defect detection technology, and more particularly to a fan and filter defect detection apparatus and method of the waste heat recovery type ventilator.

일반적으로 밀폐된 실내의 공기는 생명체의 호흡에 의해 시간이 지날수록 이산화탄소(CO2)의 함량이 증가하게 되어 생명체의 호흡에 지장을 주게 된다.In general, the air inside the sealed room is increased by the respiration of life, and the content of carbon dioxide (CO 2 ) increases, which impedes the respiration of life.

따라서, 개인 주택, 공통 주택, 사무실 등에는 실외의 신선한 공기를 실내로 제공함으로써 오염된 실내 공기를 수시로 대체해 줄 필요가 있게 되는데, 이를 위해 사용되는 것이 환기장치이다.Therefore, it is necessary to replace the contaminated indoor air from time to time by providing outdoor fresh air indoors in private houses, common houses, offices, etc., which is used for the ventilation device.

상기와 같은 환기장치 중, 도 1에 나타낸 바와 같은 폐열회수형 환기장치(100)는 냉난방기의 작동 중에 배기팬(110)을 작동시켜 실내의 공기를 실외로 배출시킬 때 열교환기(120)로 냉난방된 실내 공기의 폐열을 회수하고, 급기팬(130)을 작동시켜 실외의 신선한 공기를 실내로 급기시킬 때 상기 열교환기(120)로 회수한 실내 공기의 폐열을 실외의 신선한 공기에 부가하여 냉난방된 실내 공기의 열손실을 방지하는 에너지 절약형 환기장치로서, 통상 냉난방기의 운전비용을 20∼30% 절감할 수 있는 것으로 알려져 있다.Among the ventilation devices as described above, the waste heat recovery type ventilation device 100 as shown in FIG. 1 operates the exhaust fan 110 during the operation of the air conditioner to discharge the indoor air to the outside when the air conditioner 120 is cooled and heated. When the waste heat of the indoor air is recovered and the air supply fan 130 is operated to supply outdoor fresh air to the indoor air, the waste heat of the indoor air recovered by the heat exchanger 120 is added to the outdoor fresh air to be cooled and heated. As an energy-saving ventilator that prevents heat loss of indoor air, it is known that the operating cost of an air conditioner can be reduced by 20-30%.

상기 폐열회수형 환기장치(100)의 열교환기(120)는 배기필터(121)를 통해 실외로 배출되는 실내 공기를 필터링하고, 또한 급기필터(122)를 통해 실내로 급기되는 실외 공기를 필터링한다.The heat exchanger 120 of the waste heat recovery type ventilation device 100 filters the indoor air discharged to the outside through the exhaust filter 121, and also filters the outdoor air supplied to the interior through the air supply filter 122. .

상기 폐열회수형 환기장치(100)는 냉방된 실내 공기가 실외로 배출될 때 그 냉기를 회수한 상태에서 실외의 뜨거운 신선한 공기가 급기될 때 회수한 냉기를 실외의 뜨거운 신선한 공기에 부가하여 실내로 급기되는 공기의 온도를 낮추거나, 혹은 난방된 실내 공기가 실외로 배출될 때 그 온기를 회수한 상태에서 실외의 차가운 신선한 공기가 급기될 때 회수한 온기를 실외의 차가운 신선한 공기에 부가하여 실내로 급기되는 공기의 온도를 높힘으로써 실내 냉난방 효율이 저하되는 것을 방지한다.The waste heat recovery type ventilation apparatus 100 adds the collected cold to the outdoor hot fresh air while the cooled indoor air is discharged to the outside, and the recovered cold air is supplied to the outdoor hot fresh air. Lower the temperature of the supplied air, or recover the warmth when the heated indoor air is discharged to the outside, and add the recovered warmer to the indoor cool fresh air when the cold fresh air is supplied. By raising the temperature of the air to be supplied, the indoor cooling and heating efficiency is prevented from being lowered.

상기 폐열회수형 환기장치(100)는 사용자가 실내의 환기장치 제어용 룸 리모콘(200)을 조작함에 따라 운전 제어되며, 통상 사용자가 강, 중, 약으로 구분하여 선택한 특정 값으로 상기 배기팬(110)과 급기팬(130)의 출력을 제어한다.The waste heat recovery type ventilation device 100 is operated and controlled by a user operating a room remote control unit 200 for controlling a ventilation device in a room, and the exhaust fan 110 has a specific value selected by a user, usually divided into strong, medium, or weak. ) And the output of the air supply fan 130.

한편, 상기와 같은 종래의 폐열회수형 환기장치(100)는 상기 배기필터(121)와 급기필터(122)의 교환시기가 지나 상기 배기필터(121)와 급기필터(122)에 불순물이 많이 끼어 있으면, 상기 배기팬(110)과 급기팬(130)의 정압과 소음이 증가하고 소비 전력이 높아지고, 그 결과로 급배기 풍량비가 맞지 않게 되어 환기 효율이 저하되므로, 적기에 상기 배기필터(121)와 급기필터(122)를 교환해야 한다.On the other hand, the conventional waste heat recovery type ventilator 100 as described above has a large amount of impurities in the exhaust filter 121 and the air supply filter 122 after the replacement time of the exhaust filter 121 and the air supply filter 122 has passed. If so, the static pressure and noise of the exhaust fan 110 and the air supply fan 130 are increased, the power consumption is increased, and as a result, the exhaust air flow rate ratio is not matched, and the ventilation efficiency is lowered. And the air supply filter 122 must be replaced.

통상적으로, 상기 배기필터(121)와 급기필터(122)의 교환시기는 상기 배기팬(110)과 급기팬(130)의 가동시간을 기준으로 제조자가 규정하거나, 혹 팬 모터의 소비 전력값 혹은 팬 모터의 전압값 또는 전류값 중 어느 하나를 근거로 판단한다.Typically, the replacement time of the exhaust filter 121 and the air supply filter 122 is specified by the manufacturer based on the operating time of the exhaust fan 110 and the air supply fan 130, or the power consumption value of the fan motor or The judgment is made based on either the voltage value or the current value of the fan motor.

하지만, 상기와 같이 배기필터(121)와 급기필터(122)의 교환시기를 제조자가 규정하는 경우에는, 외부 환경이나 작동 조건에 따라 그 교환시기의 편차가 심하고, 실제로 상기 배기필터(121)와 급기필터(122)의 막힘 정도를 정확하게 파악하기 어려운 단점이 있다.However, when the manufacturer specifies the replacement timing of the exhaust filter 121 and the air supply filter 122 as described above, the variation of the replacement time is severe depending on the external environment and operating conditions, and the exhaust filter 121 and It is difficult to accurately grasp the degree of blockage of the air supply filter 122.

또한, 상기와 같이 배기필터(121)와 급기필터(122)의 교환시기를 팬 모터의 소비 전력값 혹은 팬 모터의 전압값 또는 전류값 중 어느 하나를 근거로 판단하는 경우에는, 상기 배기팬(110)과 급기팬(130)의 결함이나 다른 장치에 의한 영향으로 팬 모터의 전압값 또는 전류값이 바뀔 수 있기 때문에, 상기 배기필터(121)와 급기필터(122)의 정확한 교환시기를 판단하기 어렵다.As described above, when it is determined whether to replace the exhaust filter 121 and the air supply filter 122 based on one of the power consumption value of the fan motor, the voltage value or the current value of the fan motor, the exhaust fan ( Since the voltage value or the current value of the fan motor may be changed due to the defect of the 110 and the air supply fan 130 and other devices, it is necessary to determine the correct replacement time of the exhaust filter 121 and the air supply filter 122. it's difficult.

이 상태에서, 상기 제어부(330)는 상기 배기팬(110)과 급기팬(130)이 구동할 때, 상기 팬 회전수 감지부(310)과 팬 모터 전류 감지부(320)에 의해 실제 측정되는 특정 팬 회전수에 대응하는 팬 모터의 전류치를 상기 정상 범위와 비교하여 필터 결함 혹은 팬 결함 상태를 판정하며(S12), 바람직하게는 상기 배기팬(110)과 급기팬(130)이 구동할 때 측정되는 특정 팬 회전수에 대응하는 팬 모터의 전류치가 상기 정상 범위 이하이면 배기필터(121)와 급기필터(122) 결함으로 판정하거나, 혹은 상기 정상 범위 이상이면 상기 배기팬(110)과 급기팬(130)의 결함으로 판정한다.In this state, the control unit 330 is actually measured by the fan rotation speed detection unit 310 and the fan motor current detection unit 320 when the exhaust fan 110 and the air supply fan 130 are driven. A filter defect or a fan defect state is determined by comparing the current value of the fan motor corresponding to a specific fan rotation speed with the normal range (S12), and preferably, when the exhaust fan 110 and the air supply fan 130 are driven. If the current value of the fan motor corresponding to the specific fan speed to be measured is equal to or less than the normal range, the exhaust filter 121 and the air supply filter 122 are determined to be defective, or if the current value is greater than the normal range, the exhaust fan 110 and the air supply fan. It determines with the defect of (130).

예컨대, 도 3에 나타낸 바와 같이, 예컨대 경사진 실선으로 표시한 정상시(기준치) 팬 모터 전류치를 기준으로 정상범위가 정해진 상태에서, 만약 상기 배기팬(110)과 급기팬(130)이 구동할 때 실제로 측정되는 특정 팬 회전수에 대응하는 팬 모터의 전류치가 상기 정상 범위 이하이면, 특정 팬 회전수에 대응하는 공기량이 정상범위 보다 적은 상태에 해당하므로, 상기 제어부(330)는 필터 결함 상태를 판정하여 경보 신호를 출력한다. For example, as shown in FIG. 3, in the state where the normal range is determined based on the normal (reference value) fan motor current value indicated by the inclined solid line, for example, the exhaust fan 110 and the air supply fan 130 may be driven. When the current value of the fan motor corresponding to the specific fan speed actually measured is less than or equal to the normal range, since the air amount corresponding to the specific fan speed is smaller than the normal range, the controller 330 detects a filter defect state. It determines and outputs an alarm signal.

또한, 도 3에 나타낸 바와 같이, 경사진 실선으로 표시한 정상시(기준치) 팬 모터 전류치를 기준으로 정상범위가 정해진 상태에서, 만약 상기 배기팬(110)과 급 기팬(130)이 구동할 때 실제로 측정되는 특정 팬 회전수에 대응하는 팬 모터의 전류치가 상기 정상 범위 이상이면, 특정 팬 회전수에 대응하는 팬 모터에서 정상범위 보다 많은 양을 전류를 소모하는 상태에 해당하므로, 상기 제어부(330)는 팬 결함 상태를 판정하여 경보 신호를 출력한다.In addition, as shown in FIG. 3, when the exhaust fan 110 and the supply fan 130 are driven in a state in which the normal range is determined based on the normal (reference value) fan motor current value indicated by the inclined solid line. If the current value of the fan motor corresponding to the specific fan speed actually measured is greater than or equal to the normal range, since the fan motor corresponding to the specific fan speed corresponds to a state of consuming more current than the normal range, the controller 330 ) Determines a fan fault condition and outputs an alarm signal.

상기와 같이 제어부(330)가 배기필터(121)와 급기필터(122) 결함 혹은 배기팬(110)과 급기팬(130) 결함을 판정하여 경보 신호를 출력하면, 최종적으로 상기 경보부(340)가 이러한 판정 결과에 따라 필터 결함 혹은 팬 결함 상태를 경보등이나 경보음, 혹은 경보 문자 등으로 경보하여 사용자에게 알려준다(S13). 이에 따라서, 사용자는 적기에 배기필터(121)와 급기필터(122)를 교환하거나 혹은 배기팬(110)과 급기팬(130)을 수리할 수 있다.As described above, when the controller 330 determines the defect of the exhaust filter 121 and the air supply filter 122 or the defects of the exhaust fan 110 and the air supply fan 130 and outputs an alarm signal, the alarm unit 340 finally generates the alarm signal. According to the determination result, the filter defect or the fan defect status is alerted by an alarm lamp, an alarm sound, or an alarm character to inform the user (S13). Accordingly, the user can replace the exhaust filter 121 and the air supply filter 122 or repair the exhaust fan 110 and the air supply fan 130 in a timely manner.
