본 발명은 냉난방운전을 행하는 공기조화기에 관한 것으로, 특히 실내팬모터의 회전수를 제어하여 난방 시 토출되는 공기온도를 보다 쾌적하게 유지하는 공기 조화기의 풍량제어장치 및 그 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for performing a heating and cooling operation. More particularly, the present invention relates to an air conditioner and a method of controlling an air conditioner for more comfortably maintaining the air temperature discharged during heating by controlling the rotation speed of an indoor fan motor.

공기조화기는 실내의 뜨거운 공기를 차갑게 하여 실내로 공급하는 냉방장치와, 실내의 차가운 공기를 따뜻하게 하여 실내로 공급하는 난방장치가 있으며, 상기의 냉방기능과 난방기능을 겸한 냉난방장치도 있고, 오염된 실내공기를 청정시키는 청정기능도 포함되어지는 상황이다.The air conditioner has a cooling device that cools the indoor hot air and supplies it to the room, and a heating device that warms the cold air in the room and supplies it to the room. The air conditioner that combines the above cooling function and heating function is also contaminated. It also includes a clean function to clean indoor air.

일반적으로, 냉난방기능을 행하는 공기조화기에는 대한민국 공개특허공보 1999-0069705호가 있다.In general, the Republic of Korea Patent Publication No. 1999-0069705 is an air conditioner that performs the heating and cooling function.

동 공보에 개시된 공기조화기에서, 난방운전 시는 실내온도가 설정온도보다 낮은 경우 압축기의 주파수를 높은 주파수로 제어하고, 실내온도가 설정온도에 근접했을 때는 압축기의 주파수를 상기 경우보다 상대적으로 낮은 주파수로 제어한다. 그리고 실내온도가 설정온도에 도달했을 때는 압축기를 정지상태로 제어한 후, 다시 실내온도가 설정온도보다 일정치 만큼 낮아졌을 때 압축기를 구동해서 상기와 동일한 과정으로 제어하였다.In the air conditioner disclosed in the publication, during the heating operation, when the room temperature is lower than the set temperature, the frequency of the compressor is controlled at a high frequency, and when the room temperature is close to the set temperature, the frequency of the compressor is lower than the above. Control by frequency When the indoor temperature reaches the set temperature, the compressor is controlled to a stop state, and when the indoor temperature is lowered by a predetermined value than the set temperature, the compressor is driven and controlled in the same process as described above.

반면, 냉방운전 시는 실내온도가 설정온도보다 높은 경우 압축기의 주파수를 높은 주파수로 제어해서 빠르게 실내온도가 낮아질 수 있도록 하고, 실내온도가 설정온도에 근접했을 때는 압축기의 주파수를 상기 경우보다 상대적으로 낮은 주파수로 제어한다. 그리고 실내온도가 설정온도에 도달했을 때는 압축기를 정지상태로 제어한 후, 다시 실내온도가 설정온도보다 일정치 만큼 높아졌을 때 압축기를 적정주파수로 구동하는 제어를 수행하였다.On the other hand, during the cooling operation, if the indoor temperature is higher than the set temperature, the compressor frequency is controlled to a high frequency so that the indoor temperature can be lowered quickly. When the indoor temperature is close to the set temperature, the frequency of the compressor is relatively higher. Control at low frequency. When the indoor temperature reached the set temperature, the compressor was controlled to a stop state, and then, when the indoor temperature was raised by a predetermined value higher than the set temperature, the compressor was driven at an appropriate frequency.

그런데, 이러한 종래 공기조화기는 실제 토출되는 공기온도를 고려하지 않고 실내온도와 설정온도만을 기준으로 압축기의 주파수를 업(UP)/다운(DOWN) 제어(인버터형의 경우)하거나 압축기를 온/오프 제어(정속형)하고 있기 때문에 실제 토출되는 공기의 온도가 과난방 또는 과냉방 상태로 토출되어 사용자에게 불쾌감을 줄 수 있다.By the way, such a conventional air conditioner does not consider the actual discharged air temperature, the up / down control of the compressor frequency (only in the case of the inverter type) or the compressor on / off based only on the room temperature and the set temperature. Since it is controlled (constant speed type), the temperature of air actually discharged is discharged in an overheating or supercooling state, which may cause discomfort to the user.

이에, 실내팬모터의 풍량을 제어하여 토출되는 공기온도를 제어하는 방식이 제안되었으나, TAP모터를 사용하는 일반적인 실내팬모터의 경우 풍량이 냉방→ 송풍→ 난방의 순으로 많게 되어 냉방운전을 할 때 실내열교환기에 맺히는 이슬에 의해 풍량 저하가 큰 경우 상대적으로 난방 시 실내팬모터의 풍량은 과다하여 실외열교환기가 결빙될 가능성이 크고, 실내기에서 토출되는 공기온도가 낮아 체감 난방성능이 저하되는 경우가 발생할 수 있다.Therefore, a method of controlling the air temperature discharged by controlling the air volume of the indoor fan motor has been proposed, but in the case of a general indoor fan motor using a TAP motor, the air volume increases in the order of cooling → blowing → heating when the cooling operation is performed. If the air volume decreases due to dew that forms on the indoor heat exchanger, the airflow of the indoor fan motor is relatively high when heating, and the outdoor heat exchanger is likely to freeze. Can be.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 본 발명의 목적은 운전모드에 따라 실내팬모터의 목표 회전수를 별도로 설정하여 난방 시 토출되는 공기온도를 보다 쾌적하게 유지할 수 있는 공기조화기의 풍량제어장치 및 그 방법을 제공하는데 있다.Therefore, the present invention is to solve the conventional problems as described above, an object of the present invention is to set the target rotational speed of the indoor fan motor separately according to the operation mode to maintain a more comfortable air temperature discharged during heating An air conditioner and an apparatus for controlling an air conditioner are provided.

도 3은 본 발명에 의한 공기조화기의 풍량제어방법의 동작 흐름도이다.3 is an operation flowchart of the airflow control method of the air conditioner according to the present invention.

사용자가 운전모드(예를 들면, 난방)와 설정온도, 설정풍량(난방 목표 회전수) 등의 정보를 설정하면, 설정된 정보가 신호입력부(100)를 통해 제어부(140)에 입력된다(S100).When the user sets information such as an operation mode (for example, heating), a set temperature, a set air volume (heating target rotational speed), and the like, the set information is input to the controller 140 through the signal input unit 100 (S100). .

따라서, 제어부(140)는 설정된 운전모드에 따라 밸브구동부(180)를 제어해서 사방밸브(14)가 난방싸이클로 전환되도록 제어하고, 운전 온인가를 판단하여(S110), 운전 온이면 설정풍량(난방 목표 회전수)에 따라 실내팬모터(54)를 구동시킨다(S120).Therefore, the control unit 140 controls the valve driving unit 180 to switch to the four-way valve 14 to the heating cycle according to the set operation mode, and determines whether the operation is on (S110). The indoor fan motor 54 is driven according to the target rotation speed (S120).

이후, 제어부(140)는 압축기(12) 온 조건인가를 판별하여, 온 조건이면 소정의 지연시간을 가지고 압축기(12)를 운전시킨다(S130~S140).Thereafter, the controller 140 determines whether the compressor 12 is in an on condition, and if the controller is in the on condition, operates the compressor 12 with a predetermined delay time (S130 to S140).

상기 압축기(12)의 운전에 따라 난방운전이 개시되면, 실내팬모터(54)의 회전수를 회전수감지부(130)에서 감지하여 제어부(140)에 입력한다.When the heating operation is started according to the operation of the compressor 12, the rotation speed of the indoor fan motor 54 is sensed by the rotation speed sensing unit 130 and input to the controller 140.

따라서, 제어부(140)는 입력되는 실내팬모터(54)의 회전수에 따라 실내기(50)에서 토출되는 풍량을 검출한다(S150).Therefore, the controller 140 detects the amount of air discharged from the indoor unit 50 according to the rotation speed of the indoor fan motor 54 input (S150).

이때, 실내기(50)에서 토출되는 공기의 온도를 토출온도감지부(120)에서 감지하여 제어부(140)에 입력하고(S160), 제어부(140)는 입력되는 토출공기온도와 토출풍량에 따라 실내팬모터(54)의 회전수를 다단계로 제어하여 난방 시 목표 회전수를 별도로 설정한다(S170).At this time, the temperature of the air discharged from the indoor unit 50 is sensed by the discharge temperature detection unit 120 and input to the control unit 140 (S160), the control unit 140 is indoors according to the discharge air temperature and the discharge air volume input By controlling the rotation speed of the fan motor 54 in multiple stages, the target rotation speed is separately set at heating (S170).

별도로 설정되는 난방의 실내팬모터(54) 목표 회전수는 냉방의 강풍 목표 회전수와 중풍 목표 회전수의 차이를 다수로 나누어(예를 들어, 4등분) 난방 목표 회전수를 냉방 목표 회전수 기준으로 최대 ±1TAP까지 조절 가능하게 하며, 이러한 난방 목표 회전수는 실내기(50) 리모콘이나 조작부를 통해 설정할 수도 있다.The target fan speed of the indoor fan motor 54 of the heating, which is set separately, divides the difference between the strong wind target speed and the middle wind target speed of cooling by a large number (for example, by four), and the heating target speed is based on the cooling target speed. Up to ± 1TAP, and the heating target rotation speed may be set through the indoor unit 50 remote control or the control unit.

이와 같이, 본 발명은 사용자가 운전모드(난방)와 풍량을 선택하는 경우, 운전모드에 따라 실내팬모터(54)의 목표 회전수를 제어부(140)에서 별도로 설정하고, 토출공기온도와 토출풍량에 따른 최적의 회전수를 추정하여 실내팬모터(54)의 회전수를 다단계로 제어함으로서 체감 난방성능과 압축기(12)의 신뢰성을 향상시킬 수 있게 된다.As described above, when the user selects the operation mode (heating) and the air volume, the controller 140 separately sets the target rotational speed of the indoor fan motor 54 according to the operation mode, and discharge air temperature and discharge air volume. By estimating the optimum rotational speed according to the multi-stage control of the rotational speed of the indoor fan motor 54 it is possible to improve the haptic heating performance and the reliability of the compressor (12).
