본 발명은 공기조화기의 제상운전 제어방법에 관한 것으로써, 특히 실외팬의 회전수를 감지하고, 상기 회전수에 비례하여 제상운전시간이 증가하도록 보상하고여 충분히 제상이 되도록하는 공기조화기의 제상운전 제어방법에 관한 것이다.The present invention relates to a defrosting operation control method of an air conditioner, and more particularly, to detect the rotational speed of an outdoor fan, and to compensate for the increase in the defrosting operation time in proportion to the rotational speed, so as to sufficiently defrost the air conditioner. It relates to a defrosting operation control method.

일반적으로 공기조화기는 실내의 공기를 용도 및 목적에 따라 가장 적합한 상태로 유지하기 위한 장치이다. In general, an air conditioner is a device for maintaining indoor air in a state most suitable for use and purpose.

즉, 사용자 요구에 의해서 난방 사이클 및 냉방 사이클을 구동하고, 상기 난방 사이클의 운전에 의해서 추운 겨울에 실내를 따뜻하게 조성하며, 상기 냉방 사이클의 운전에 의해서 더운 여름에 실내를 시원하게 조성한다. 또한, 공기조화기는 실내의 습도를 조절하며, 실내의 공기를 쾌적한 청정상태로 조절한다. That is, the heating cycle and the cooling cycle are driven at the user's request, the room is warmly formed in the cold winter by the operation of the heating cycle, and the room is made cool in the hot summer by the operation of the cooling cycle. In addition, the air conditioner controls the humidity in the room, and controls the air in the room to a comfortable clean state.

도 1은 일반적인 공기조화기의 냉/난방 사이클을 간략하게 나타낸 도면이다. 1 is a view briefly illustrating a cooling / heating cycle of a general air conditioner.

도 1을 참조하면, 난방 사이클(H)에 의한 난방 운전은, 먼저 압축기(30)에서 냉매를 압축한다. 압축된 냉매는 실내열 교환기(20)로 전달된다. 이때, 실내열 교환기(20)에 흐르는 냉매가 실내측으로 열을 방출하여, 실내측으로 따뜻한 바람이 토출된다. 그리고, 상기 실내열 교환기(20)를 통과한 냉매는 도시되지 않은 팽창밸브를 통해서 실외열 교환기(10)로 흡입된다. 이때, 상기 실외열 교환기(10)가 증발 동작을 수행하여 차가운 공기를 실외로 토출시킨다. Referring to FIG. 1, the heating operation by the heating cycle H first compresses the refrigerant in the compressor 30. The compressed refrigerant is delivered to the indoor heat exchanger 20. At this time, the refrigerant flowing in the indoor heat exchanger 20 discharges heat to the indoor side, and warm wind is discharged to the indoor side. The refrigerant passing through the indoor heat exchanger 20 is sucked into the outdoor heat exchanger 10 through an expansion valve (not shown). At this time, the outdoor heat exchanger 10 performs an evaporation operation to discharge cold air to the outside.

한편, 냉방사이클(C)에 의한 냉방 운전은, 먼저 압축기(30)에서 냉매를 압축한다. 상기 압축된 냉매는 실외열 교환기(10)로 전달된다. 실외열 교환기(10)는 전 달된 냉매를 응축하고, 응축된 냉매를 도시되지 않은 팽창밸브를 통해서 실내열 교환기(20)로 전달시킨다. 따라서 실내열 교환기(20)가 구동됨에 따라 냉매가 실내 공기의 열을 흡수하여 실내측으로 차가운 공기가 토출된다.On the other hand, in the cooling operation by the cooling cycle C, the compressor 30 first compresses the refrigerant. The compressed refrigerant is delivered to the outdoor heat exchanger 10. The outdoor heat exchanger 10 condenses the delivered refrigerant and delivers the condensed refrigerant to the indoor heat exchanger 20 through an expansion valve (not shown). Therefore, as the indoor heat exchanger 20 is driven, the refrigerant absorbs heat from the indoor air and discharges cool air to the indoor side.

이와 같이 하나의 장치를 이용해서 냉/난방장치로 사용하는 경우, 냉방운전의 역사이클을 통해서 난방사이클(H)을 구현하고, 마찬가지로 난방운전의 역사이크을 통해서 냉방사이클(C)을 구현하게 된다.As such, when using a single device as a cooling / heating device, the heating cycle (H) is implemented through the reverse cycle of the cooling operation, and the cooling cycle (C) is implemented through the history spike of the heating operation.

그리고, 실외기에는 실외팬(15)을 구비하고, 실내기에는 실내팬(25)을 구비하고 있으며, 이러한 팬은 열교환기에 흐르는 공기 사이의 열교환 작용을 촉진시키는 역할을 담당한다. In addition, the outdoor unit is provided with an outdoor fan 15, and the indoor unit is provided with an indoor fan 25, and the fan plays a role of promoting heat exchange between the air flowing in the heat exchanger.

한편, 상기 공기조화기가 난방운전을 수행할 때, 상기 실외열 교환기(10) 표면에는 서리가 결빙되며, 이러한 서리는 실외열 교환기(10)의 열전달 성능을 현저히 저하시킨다. 따라서, 상기 공기조화기는 실외열 교환기(10)에 일정한 정도의 서리가 결빙되면, 제어부의 제어에 의해 실외열 교환기(10) 표면에 결빙된 서리를 제상시키는 제상운전을 수행한다.On the other hand, when the air conditioner performs a heating operation, frost is frozen on the surface of the outdoor heat exchanger 10, this frost significantly lowers the heat transfer performance of the outdoor heat exchanger (10). Therefore, when the frost of a certain degree is frozen in the outdoor heat exchanger 10, the air conditioner performs a defrosting operation of defrosting the frost frozen on the surface of the outdoor heat exchanger 10 under the control of the controller.

상기 제상운전은 난방운전이 수행되는 중간중간에 실외열 교환기(10)의 표면에 생긴 결빙을 해빙시키기 위하여, 소정시간동안 냉방운전을 수행하는 것을 의미한다. 상기 냉방운전이 수행되는 동안 실외열 교환기(10)는 따뜻한 공기를 토출하게 되고, 이때 발생되는 열에 의해서 실외열 교환기(10)의 표면을 덮은 결빙이 해빙되는 것이다. The defrosting operation means that the cooling operation is performed for a predetermined time in order to thaw ice generated on the surface of the outdoor heat exchanger 10 during the middle of the heating operation. The outdoor heat exchanger 10 discharges warm air while the cooling operation is performed, and freezing of the outdoor heat exchanger 10 is thawed by heat generated at this time.

도 2는 종래 기술에 따른 공기조화기의 제상운전 제어방법을 나타내는 흐름 도이다. 2 is a flow chart showing a defrosting operation control method of the air conditioner according to the prior art.

도 2를 참조하면, 공기조화기가 난방운전을 수행하는 중에는 상기 실외팬(15),실내팬(25), 압축기(30)가 모두 구동된다. 난방운전이 수행되는 동안 제어부는 제상운전을 수행하기 위한 조건인가를 계속해서 판단하게 된다. 2, the outdoor fan 15, the indoor fan 25, and the compressor 30 are all driven while the air conditioner performs the heating operation. While the heating operation is performed, the controller continuously determines whether it is a condition for performing the defrosting operation.

일반덕으로 난방운전이 기설정된 일정시간동안 수행된 후, 실외배관온도가 일정온도 이하이면, 제어부는 실외열 교환기(10)에 서리가 착상된 것으로 판단하여, 상기 착상된 서리를 제거하기 위한 제상운전을 시작하게 된다. In general, after the heating operation is performed for a predetermined period of time, if the outdoor piping temperature is less than a predetermined temperature, the control unit determines that the frost is implanted in the outdoor heat exchanger 10, the defrost for removing the frost formed Start driving.

상기 제상운전 과정(S100)에서 제어부는 상기 실외팬(15)을 정지시키고, 사이클을 냉방사이클로 전환시킨다(S110). 상기 제상운전이 수행되는 동안에는 실외열 교환기(10)는 기설정된 제상필요시간(Td)동안 응축기로 동작되면서 열을 방출하고(S120), 이렇게 방출되는 열이 열교환면에 덮인 서리를 해빙시킨다. In the defrosting operation (S100), the controller stops the outdoor fan 15 and converts the cycle into a cooling cycle (S110). While the defrosting operation is performed, the outdoor heat exchanger 10 emits heat while operating as a condenser for a predetermined defrosting time Td (S120), and the heat thus released thaws the frost covered on the heat exchange surface.

이때, 제어부는 공기조화기가 제상운동하는 시간을 판단하는데(S130), 상기 제상운전시간이 제상필요시간(Td)미만으로 수행되면 제상운전을 계속 수행한다(140). 한편, 상기 제상운전시간이 제상필요시간(Td)을 초과하면 제상운전을 종료(S150)하고, 상기 실외팬(15)을 다시 구동하여 난방운전을 수행한다(S160).At this time, the control unit determines the time for the dehumidification movement of the air conditioner (S130), if the defrosting operation time is less than the defrost required time (Td) continues to perform the defrosting operation (140). On the other hand, if the defrosting operation time exceeds the defrosting required time (Td) the defrosting operation is terminated (S150), and the outdoor fan 15 is driven again to perform a heating operation (S160).

이러한 기설정된 제상운전시간을 이용하는 방식의 공기조화기의 제상운전 제어방법은 실외팬을 정지시키나, 겨울의 눈보라와 같은 실외 대류에 의해 실외팬(15)이 강제로 회전하는 경우가 있어, 평균 데이터에 의하여 기설정된 제상운전시간만큼 제상운전을 수행하면, 실질적으로 기대치보다 실외열 교환기의 해빙효과가 저하되는 문제점이 있다. The defrosting operation control method of the air conditioner using the predetermined defrosting operation time stops the outdoor fan, but the outdoor fan 15 may be forcibly rotated by outdoor convection such as a winter snowstorm, and thus the average data. When the defrosting operation is performed for a predetermined defrosting operation time, the thawing effect of the outdoor heat exchanger is substantially lowered than expected.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 공기조화기의 제상운전시에 실외팬의 회전이 감지되면, 상기 실외팬의 회전수를 감지하고, 상기 회전수에 비례하여 제상운전시간을 늘리도록 보상하는 공기조화기의 제상운전 제어방법을 제공하는데에 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, if the rotation of the outdoor fan is detected during the defrosting operation of the air conditioner, the rotational speed of the outdoor fan is detected, the defrost in proportion to the rotational speed It is an object of the present invention to provide a defrosting operation control method of an air conditioner that compensates for an increase in operating time.

상기한 과제를 해결하기 위한 본 발명에 따른 공기조화기의 제상운전 제어방법은 공기조화기의 제상운전시에 상기 실외팬의 회전이 감지되면, 실외팬의 회전수를 감지하는 제 1 단계와, 상기 감지된 실외팬의 회전수에 비례하여 제상운전시간을 보상하는 제 2 단계를 포함하여 구성되는 것을 특징으로 한다. Defrost operation control method of the air conditioner according to the present invention for solving the above problems is a first step of detecting the rotational speed of the outdoor fan, if the rotation of the outdoor fan is detected during the defrost operation of the air conditioner; And a second step of compensating for the defrosting operation time in proportion to the detected rotation speed of the outdoor fan.

이때, 상기 제 1 단계에서 상기 실외팬의 회전수를 감지하는 감지횟수(N)가 적어도 1회 이상인 것을 특징으로 한다. At this time, the detection frequency (N) for detecting the rotational speed of the outdoor fan in the first step is characterized in that at least one or more times.

상기 감지횟수(N)당 실외팬 회전수(이하, 평균회전수와 동일)를 산정하는 과정과, 상기 실외팬의 평균회전수에 기설정된 단위회전수를 나누어 보상비율(R)를 산정하는 과정과, 상기 보상비율(R)을 기설정된 표준 제상 필요시간(Ts)에 곱하여 최종 제상운전시간을 산정하는 과정을 포함하여 구성되는 것을 특징으로 한다. The process of calculating the outdoor fan rotation speed (hereinafter, equal to the average rotational speed) per detection frequency (N) and the process of calculating the compensation ratio (R) by dividing a predetermined unit rotational speed by the average rotational speed of the outdoor fan. And calculating a final defrosting operation time by multiplying the compensation ratio R by a predetermined standard defrosting required time Ts.

이때, 상기 산정된 보상비율이(R)이 1보다 작거나 같다면, 최종 보상비율(R')은 1로 설정된다. 한편, 상기 산정된 보상비율(R)이 1보다 크다면, 최종 보상비율 (R')은 1+(R/10)로 설정되는 것을 특징으로 한다. In this case, if the calculated compensation ratio R is less than or equal to 1, the final compensation ratio R 'is set to one. On the other hand, if the calculated compensation ratio (R) is greater than 1, the final compensation ratio (R ') is characterized in that it is set to 1 + (R / 10).

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 3은 본 발명에 따른 공기조화기의 제상운동 제어방법을 나타내는 흐름도이다. 3 is a flowchart illustrating a method of controlling defrost motion of an air conditioner according to the present invention.

도 3을 참조하면, 공기조화기의 난방운전중에 실외열 교환기의 표면에 결빙된 서리를 제상시키는 제상운전이 수행되면(S200), 제어부에서 실외팬을 정지시킨다(S210). 이때, 상기 제어부는 실외팬이 외부에서 일어나는 강풍과 같은 외부대류에 의해 회전하는 것을 계속 감지한다. Referring to FIG. 3, when the defrosting operation of defrosting frost frozen on the surface of the outdoor heat exchanger is performed during the heating operation of the air conditioner (S200), the controller stops the outdoor fan (S210). In this case, the controller continues to sense that the outdoor fan is rotated by external convection such as a strong wind occurring outside.

그리고, 상기 제어부에 의해 실외팬이 회전되는 것을 감지하면, 제어부에 구비된 카운터에 의해 실외팬의 회전수를 체크한다. 이때, 상기 실외팬의 회전수는 카운터에 의해 분할하여 체크되는데, 이러한 실외팬의 회전수를 체크하는 감지횟수(N)는 적어도 1회 이상 수행된다(S300).When the outdoor fan is rotated by the control unit, the rotation speed of the outdoor fan is checked by a counter provided in the control unit. At this time, the rotation speed of the outdoor fan is checked by dividing by a counter, and the detection frequency N for checking the rotation speed of the outdoor fan is performed at least once (S300).

이때, 상기 감지횟수(N)당 실외팬의 누적회전수를 산정하여 실외팬의 평균회전수를 설정한다(S310).In this case, the average rotational speed of the outdoor fan is set by calculating the cumulative rotational speed of the outdoor fan per detection frequency (N) (S310).

다음으로, 상기 평균회전수에 기설정된 단위회전수를 나누어 보상비율(R)을 산정한다(S320). 이때, 상기 단위회전수는 평균적인 제상시간에 따른 실외팬이 회전하는 횟수를 산출한 데이터(data)이고, 사용자에 의하여 보상비율을 조정할 필요가 있을 경우에 변경할 수 있다.Next, the compensation ratio (R) is calculated by dividing the preset unit rotation speed by the average rotation speed (S320). In this case, the unit rotation speed is data obtained by calculating the number of times the outdoor fan rotates according to the average defrosting time, and may be changed when the user needs to adjust the compensation ratio.

이때, 상기 산정된 보상비율(R)이 1 보다 작거나 같을 경우에는 최종 보상비율(R')을 1 로 설정하고, 상기 제어부에 기설정된 표준제상필요시간(Ts)과 곱하여 산정된 값을 최종 제상운전시간으로 설정한다. 이때, 상기 표준제상필요시간(Ts)은 공기조화기의 실외열 교환기에 서리가 착상될 시에, 제상운전을 수행하여야 하는 시간의 평균적인 데이터값이다.In this case, when the calculated compensation ratio R is less than or equal to 1, the final compensation ratio R 'is set to 1, and the value calculated by multiplying the standard defrosting time Ts preset in the controller is final. Set the defrosting operation time. At this time, the standard defrosting time Ts is an average data value of time to perform defrosting operation when frost is formed on the outdoor heat exchanger of the air conditioner.

또한, 상기 산정도니 보상비율(R)이 1보다 클 경우는 최종 보상비율(R')을 다음과 같은 수학식에 의하여 산정한다. In addition, when the calculation rate R is greater than 1, the final compensation ratio R 'is calculated by the following equation.

(수학식) (Mathematical formula)

R' = 1 + (R/10)R '= 1 + (R / 10)

위의 수학식에 의하여 산정된 최종 보상비율(R')을 상기 표준제상필요시간(Ts)과 곱하여 최종 제상운전시간(Td)을 설정한다(S330 내지 S350).The final defrosting operation time Td is set by multiplying the final compensation ratio R 'calculated by the above equation with the standard defrosting required time Ts (S330 to S350).

이와 같이 본 발명에 의해 설정된 최종 제상운전시간(Td)보다 실제로 공기조화기가 수행하는 제상운전시간이 작다면 제상운전을 계속 수행하고(S260), 상기 최종 제상운전시간(Td)을 실제로 공기조화기가 수행하는 제상운전시간이 초과한다면, 제상운전이 종료되고, 실외팬을 다시 정상적으로 운전되도록 한다(S240 내지 S250).As described above, if the defrosting operation time actually performed by the air conditioner is smaller than the final defrosting operation time Td set by the present invention, the defrosting operation is continued (S260), and the final defrosting operation time Td is actually If the defrosting operation time is exceeded, the defrosting operation is terminated, and the outdoor fan is normally operated again (S240 to S250).

이상과 같이 본 발명에 의한 공기조화기의 제상운전 제어방법을 예시된 도면을 참조로 설명하였으나, 본 명세서에 개시된 실시예와 도면에 의해 본 발명은 한정되지 않고, 기술사상이 보호되는 범위 이내에서 응용될 수 있다. As described above, the method for controlling the defrosting operation of the air conditioner according to the present invention has been described with reference to the illustrated drawings. However, the present invention is not limited by the embodiments and drawings disclosed herein, and the technical idea is within the scope of protection. Can be applied.

상기와 같이 구성되는 본 발명에 따른 공기조화기의 제상운전 제어방법은 공기조화기의 제상운전시 실외팬이 강제로 회전될 경우, 상기 실외팬의 회전수를 체크하고, 상기 회전수에 비례하여 최종제상운전시간을 산정하고, 충분히 제상이 되도록함으로써, 누적 결빙에 의해 공기조화기의 난방운전성능이 저하되는 것을 최소화시키는 효과가 있다. Defrosting operation control method of the air conditioner according to the present invention configured as described above, when the outdoor fan is forcibly rotated during the defrosting operation of the air conditioner, check the rotational speed of the outdoor fan, in proportion to the rotational speed By calculating the final defrosting operation time and making the defrosting sufficiently, there is an effect of minimizing the deterioration of the heating operation performance of the air conditioner by accumulated ice.
