본 발명은 멀티형 공기조화기의 팬 모터 제어방법에 관한 것으로, 특히 정지한 벽걸이형 실내기의 난방 운전을 위한 기동 시 온도센서의 오측정에 의한 풍량설정 오류를 방지하기 위해 측정온도와 설정온도의 비교결과에 따라 강제로 팬 모터를 제어하는 방법에 관한 것이다.The present invention relates to a method for controlling a fan motor of a multi-type air conditioner, and in particular, a comparison between a measured temperature and a set temperature in order to prevent an air volume setting error due to an incorrect measurement of a temperature sensor during start-up for heating operation of a stationary wall-mounted indoor unit. The present invention relates to a method of forcibly controlling a fan motor.

일반적으로, 공기조화기 본체의 공기 송출구에 복수 매의 좌우 플랩(flap)을 구비하고, 이들 좌우 플랩을 동기시켜 자동 또는 스윙 모드로 풍향 제어가 가능하게 한 벽걸이형 공지조화기가 알려져 있다. BACKGROUND ART In general, a wall-mounted air conditioner is provided which has a plurality of left and right flaps at an air outlet of an air conditioner main body, and allows the wind direction control to be performed in an automatic or swing mode by synchronizing these left and right flaps.

상기 벽걸이형 공기조화기에는, 실내기의 흡입구의 근방에 온도센서를 설치하고, 흡입구로부터 흡입되는 실내의 공기의 온도를 실내온도로서 검출하도록 한다. In the wall-mounted air conditioner, a temperature sensor is provided in the vicinity of the intake port of the indoor unit, and the temperature of the room air sucked from the intake port is detected as the room temperature.

그런데, 벽걸이형 공기조화기에서는, 온도센서에 의해 검출한 실내온도와 설정온도의 온도차에 근거하여 압축기를 온/오프한다. 즉, 실내온도가 대략 설정온도와 같게 되면, 압축기를 오프한다. By the way, in the wall-mounted air conditioner, the compressor is turned on / off based on the temperature difference between the room temperature and the set temperature detected by the temperature sensor. That is, when the room temperature becomes approximately equal to the set temperature, the compressor is turned off.

한편, 실내기의 취출구의 근방에 온도센서를 설치하는 경우, 실내기를 정지시킨 후 재 기동 시 온도센서에 의한 검출온도가 열교환기의 온도의 영향을 받는다.On the other hand, when the temperature sensor is installed near the outlet of the indoor unit, the temperature detected by the temperature sensor during the restart after the indoor unit is stopped is affected by the temperature of the heat exchanger.

즉, 난방 운전 시에는, 열교환기의 근방의 공기가 열교환기의 의해 가열되고, 대류에 의해 흡입구의 근방의 온도도 상승된다. 이것에 의해, 흡입구의 근방에 설치되는 온도센서의 주위의 온도가 실제의 실내온도보다도 높게 되고, 온도센서에 의해 검출하는 실내온도의 오차가 크게 되고 만다. That is, in the heating operation, the air in the vicinity of the heat exchanger is heated by the heat exchanger, and the temperature in the vicinity of the suction port is also raised by convection. As a result, the temperature around the temperature sensor provided near the suction port becomes higher than the actual room temperature, and the error of the room temperature detected by the temperature sensor becomes large.

그 때문에, 현 실내온도가 설정온도에 도달한 경우에도 팬이 계속 저속으로 구동하게 되는 등의 문제점이 있었다.Therefore, there is a problem that the fan continues to run at a low speed even when the current room temperature reaches the set temperature.

또한, 상기 종래 방법은 정지측 실내기를 운전 시작 시 바로 10분간 최저풍으로 구동한 이후에 측정한 실내온도와 설정온도를 비교하는데, 이로 인하여 실제 실내온도가 높지 않은 상황에서의 설정풍량으로 운전하지 못하여 난방운전이 제대로 되지 않는 문제점이 있었다.In addition, the conventional method compares the measured indoor temperature and the set temperature after driving the stationary indoor unit at the lowest wind for 10 minutes immediately at the start of operation, and thus does not operate at the set air volume in a situation where the actual indoor temperature is not high. There was a problem that the heating operation did not work properly.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 창안한 것으로, 정지한 실내기의 난방 운전을 위한 기동 시 온도센서의 오측정에 의한 풍량설정 오류를 방지하기 위해 측정온도와 설정온도의 비교결과에 따라 강제로 팬 모터를 제어하는 방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and compares the measured temperature and the set temperature to prevent the air flow rate setting error due to the erroneous measurement of the temperature sensor during start-up for heating operation of the stationary indoor unit. The purpose is to provide a method of forcibly controlling the fan motor according to the result.

이와 같은 목적을 달성하기 위한 본 발명 멀티형 공기조화기의 팬 모터 제어방법은, 멀티형 공기조화기의 난방 운전 시, 정지측 벽걸이형 실내기를 운전시킬 경우, 측정한 실내온도가 설정온도 이하인가를 판단하고, 판단결과에 따라 팬 모터를 설정풍량 또는 최저풍량으로 가변 제어하는 것을 특징으로 하는 한다.In the fan motor control method of the multi-type air conditioner of the present invention for achieving the above object, when the stationary wall-mounted indoor unit is operated during the heating operation of the multi-type air conditioner, it is determined whether the measured room temperature is below the set temperature. According to the determination result, the fan motor is variably controlled to a set air flow rate or a minimum air flow rate.

이하, 본 발명의 실시예에 따른 동작 과정을 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an operation process according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 실시예를 적용하기 위한 벽걸이형 에어컨의 전면구조를 보인 구성도로서, 이에 도시한 바와 같이 공조하는 실내에 설치되는 벽걸이형 실내기(100)는 케이싱에 의해 내부가 덮혀있는데, 이 케이싱의 내에는 플로우 팬, 필터 가 배치되어 있고, 상기 케이싱의 전면측으로부터 상면측으로 형성되어 있는 흡입구(200)와, 하부에는 취출구(300)가 형성되어 있다. 1 is a block diagram showing the front structure of the wall-mounted air conditioner for applying an embodiment of the present invention, the wall-mounted indoor unit 100 installed in the air conditioning room as shown therein is covered by the casing, A flow fan and a filter are disposed in the casing, the inlet port 200 formed from the front side of the casing to the upper surface side, and the outlet port 300 are formed in the lower portion.

상기 취출구(300) 내에는 좌,우 플랩 및 상,하 플랩이 설치되어 있고, 이 상,하,좌,우 플랩에 의해 취출구(300)로부터 취출되는 공조풍의 방향이 변하도록 되어 있다.Left and right flaps and upper and lower flaps are provided in the outlet port 300, and the direction of air-conditioning air blown out from the outlet port 300 is changed by the upper, lower, left and right flaps.

또한, 상기 벽걸이형 실내기(100)의 온도센서(400)는 상기 흡입구(200)와 열교환기(미도시)의 사이에 배치되어 플로우 팬에 의해 흡입구로부터 케이싱 내에 흡입한 공기의 온도를 검출할 수 있도록 되어 있다.In addition, the temperature sensor 400 of the wall-mounted indoor unit 100 is disposed between the suction port 200 and the heat exchanger (not shown) to detect the temperature of the air sucked into the casing from the suction port by the flow fan. It is supposed to be.

이와 같이 구성한 본 발명의 실시예의 동작 과정을 설명하면 다음과 같다.Referring to the operation of the embodiment of the present invention configured as described above are as follows.

도 2는 본 발명의 실시예에 따른 벽걸이형 실내기의 팬 모터 제어 동작을 보인 흐름도로서, 이에 도시한 바와 같이 정지측 벽걸이형 실내기(100)의 리모콘으로부터 난방운전 모드가 선택 신호를 리모콘제어센서(500)에서 감지하면(S200) 열교환기의 온도가 비교적 높고, 온도센서(400)가 열교환기의 근처에 배치되기 때문에 대류에 의해 온도센서(400)의 주위 온도가 서서히 상승한다. 이로 인하여 온도센서(400)에 의해 측정되는 온도가 실내온도를 크게 달리 하게 된다.2 is a flowchart illustrating a fan motor control operation of the wall-mounted indoor unit according to the embodiment of the present invention. As shown in FIG. 2, the heating operation mode selects a signal from the remote controller of the stationary wall-mounted indoor unit 100. If detected at 500 (S200), the temperature of the heat exchanger is relatively high, and since the temperature sensor 400 is disposed near the heat exchanger, the ambient temperature of the temperature sensor 400 gradually increases due to convection. As a result, the temperature measured by the temperature sensor 400 greatly changes the room temperature.

따라서, 오측정에 의한 팬 모터의 구동을 방지하고자 먼저 측정한 실내온도와 설정온도를 비교한다(S210).Therefore, in order to prevent the fan motor from being driven due to an incorrect measurement, the measured room temperature and the set temperature are first compared (S210).

상기 단계(S210)의 비교 결과 설정온도를 초과하는 경우, 팬 모터를 설정풍량으로 강제 운전기간(예를 들어 5분) 동안 강제로 구동한다(S220). If the comparison result of the step (S210) exceeds the set temperature, the fan motor is forcibly driven for a driving period (for example, 5 minutes) at the set wind volume (S220).

이후, 상기 강제 운전기간 동안 구동이 끝나면 다시 실내 측정온도와 설정온도를 재 비교하고(S230), 이 비교결과 설정온도를 초과하면 팬 모터를 최저풍향(530rpm)으로 구동하고(S240), 설정온도 이하면 설정풍량으로 운전을 시작한다(S250). Thereafter, when the driving is completed during the forced driving period, the indoor measurement temperature is again compared with the set temperature (S230), and when the comparison result exceeds the set temperature, the fan motor is driven at the minimum wind direction (530 rpm) (S240), and the set temperature. In this case, operation starts with the set air volume (S250).

또한, 상기 단계(S240)에서 최저풍으로 운전하는 경우에는 설정온도 이하가 될 때까지 최저풍 운전 후 온도를 재 비교하는 단계(S230)의 동작 과정을 되풀이 한다.In addition, in the case of operating at the minimum wind in the step S240, the operation of the step S230 of comparing the temperatures after the minimum wind operation is repeated until the temperature becomes lower than the set temperature.

이상에서 설명한 바와 같이 본 발명 멀티형 공기조화기의 팬 모터 제어방법은, 실제 실내온도가 높지 않은 상황에서의 설정풍량으로 운전하지 못하여 난방운전이 제대로 되지 않는 것을 방지하며, 열교환기 대류열로 인하여 온도센서에서 오감지를 하더라도 이를 빨리 대변하여 정상운전을 할 수 있도록 하는 효과가 있다.As described above, the fan motor control method of the multi-type air conditioner of the present invention prevents the heating operation from being performed properly due to the failure to operate at the set air volume in a situation where the actual room temperature is not high, and the temperature due to the heat exchanger convection heat. Even if the sensor detects a mistake, it has the effect of quickly representing it and allowing normal operation.
