본 발명은 용량이 다른 두 개의 압축기를 구비한 멀티형 에어컨의 제습 운전 제어방법에 관한 것으로, 더욱 상세하게는 제습운전 초기에 두 개의 압축기(A, B)를 모두 구동하여 급속 제습운전을 수행한 후 실내온도와 설정온도간의 온도차(X)가 네 개의 온도 설정 구간 중 어느 구간에 속하느냐에 따라 상기 두 개의 압축기(A, B) 중 하나만을 구동하여 제습 운전을 수행함으로써, 실내부하를 빠르게 경감시키면서 신속한 제습을 하여 실내온도를 쾌적하게 유지하며, 압축기의 단속 운전 횟수를 감소시켜 소비전력을 절감시킬 수 있는 멀티형 에어컨의 제습 운전 제어방법에 관한 것이다.The present invention relates to a method for controlling dehumidification operation of a multi-type air conditioner having two compressors having different capacities, and more specifically, after performing both rapid dehumidification operation by driving both compressors (A, B) at the beginning of the dehumidification operation. According to which of the four temperature setting sections the temperature difference (X) between the room temperature and the set temperature belongs to one of the two compressors (A, B) to perform the dehumidification operation, thereby reducing the indoor load quickly The present invention relates to a dehumidifying operation control method of a multi-type air conditioner which dehumidifies and maintains a comfortable room temperature and reduces power consumption by reducing the number of intermittent operation of a compressor.

일반적으로 냉각사이클을 이용한 분리형 에어컨은 실외기의 압축기(compressor)에서 압축된 냉매를 응축기(condenser)에서 액화시킨 뒤 팽창밸브(expansion valve)를 통해 실내기의 증발기(evaporator)에서 다시 기화시켜 흡수되는 기화열에 의해 실내를 냉각시키게 된다.In general, a separate air conditioner using a cooling cycle liquefies a refrigerant compressed in a compressor of an outdoor unit in a condenser and vaporizes it again in an evaporator of an indoor unit through an expansion valve. By cooling the room.

이러한 분리형 에어컨의 일종인 멀티형 에어컨은, 실외에 통상 한 대의 실외기를 설치하고, 다수개의 실내기를 냉방시켜야 할 다수의 공간 각각 설치하여 실내를 냉방시키게 된다.The multi-type air conditioner, which is a kind of the separate air conditioner, is usually provided with one outdoor unit outdoors and a plurality of spaces for cooling a plurality of indoor units, respectively, to cool the room.

도 1은 용량이 다른 두 개의 압축기를 구비한 멀티형 에어컨을 개략적으로 나타낸 구성도이다. 여기서, 압축기(B)의 용량은 실외기 용량의 100%이고, 압축기(A)의 용량은 실외기 용량의 30%이다.1 is a configuration diagram schematically showing a multi-type air conditioner having two compressors having different capacities. Here, the capacity of the compressor B is 100% of the capacity of the outdoor unit, and the capacity of the compressor A is 30% of the capacity of the outdoor unit.

여기에 도시한 바와 같이, 하나의 실외기(10)에서 압축기(A, B)를 통해 저온저압의 기체냉매를 고온고압의 기체냉매로 압축시켜 응축기(12)에서 응축열을 외부로 방출하여 저온고압의 액체냉매로 액화시킨 후 응축기(12)의 배출구를 통해 배출된 냉매는 제1 및 제2분배관(22, 32)을 통해 스탠드형 실내기(20) 및 벽걸이형 실내기(30)로 각각 전달된다. As shown here, in one outdoor unit 10, the low-temperature low-pressure gas refrigerant is compressed to a high-temperature, high-pressure gas refrigerant through the compressors A and B to discharge the condensation heat from the condenser 12 to the outside. After liquefying with liquid refrigerant, the refrigerant discharged through the outlet of the condenser 12 is transferred to the stand type indoor unit 20 and the wall-mounted indoor unit 30 through the first and second distribution pipes 22 and 32, respectively.

이때, 스탠드형 실내기 한 대만 운전 시에는 압축기(A, B)가 모두 운전되거나 압축기(A) 또는 압축기(B) 중 하나만 운전되어 3단 용량 제어를 실현한다. 하지만, 벽걸이형 실내기만 운전 시에는 냉방용량이 맞는 압축기(A)만을 가동하여 냉방 운전을 구현한다. At this time, when only one indoor unit is operated, the compressors A and B are all operated or only one of the compressors A and B is operated to realize three-stage capacity control. However, when only the wall-mounted indoor unit is operated, only the compressor A that meets the cooling capacity is operated to implement the cooling operation.

그러면, 스탠드형 실내기(20) 및 벽걸이형 실내기(30)에서는 응축된 저온고압의 액체냉매를 제1 및 제2분배관(22, 32)을 통해 입력받아 전자팽창밸브(24, 34)를 통해 저온고압의 액체냉매를 압력강하시켜 저온저압의 기체냉매로 기화시키면서 제1 및 제2증발기(26, 36)에서 증발열을 외부로 방출하여 고온저압의 기체냉매로 변환하여 압축기(A, B)로 순환시키게 된다. Then, the stand type indoor unit 20 and the wall-mounted indoor unit 30 receive the condensed low-temperature high-pressure liquid refrigerant through the first and second distribution pipes 22 and 32 through the electronic expansion valves 24 and 34. The low-pressure and high-pressure liquid refrigerant is reduced in pressure and vaporized into a low-temperature low-pressure gas refrigerant, and the first and second evaporators 26 and 36 emit heat of evaporation to the outside to convert into a low-temperature low-temperature gas refrigerant to the compressors A and B. Will be cycled.

이때 발생되는 증발열을 실내로 송풍함으로써 실내를 냉방하게 된다. By cooling the evaporation heat generated at this time into the room to cool the room.

그리고, 스탠드형 실내기(20) 및 벽걸이형 실내기(30)에는 제1 및 제2증발기(26, 36)로 입력되는 냉매의 량을 조절하기 위한 제1 및 제2솔레노이드밸브(28, 38)가 장착되어 스탠드형 실내기(20) 및 벽걸이형 실내기(30)의 작동상태나 설정값에 따라 냉매의 유량을 조절하게 된다. In addition, the stand type indoor unit 20 and the wall-mounted indoor unit 30 include first and second solenoid valves 28 and 38 for controlling the amount of refrigerant input to the first and second evaporators 26 and 36. It is mounted to adjust the flow rate of the refrigerant in accordance with the operating state or the set value of the stand-type indoor unit 20 and the wall-mounted indoor unit 30.

도 2는 종래기술에 따른 용량이 다른 두 개의 압축기를 구비한 멀티형 에어컨의 제습 운전 제어방법을 설명하기 위한 흐름도이다.2 is a flowchart illustrating a dehumidification operation control method of a multi-type air conditioner having two compressors having different capacities according to the related art.

여기에 도시한 바와 같이, 종래기술에 따른 용량이 다른 두 개의 압축기를 구비한 멀티형 에어컨의 제습 운전 제어방법은 먼저, 운전모드가 제습모드로 설정되어 있는지 여부를 판단한다(S10).As shown here, the dehumidification operation control method of the multi-type air conditioner having two compressors having different capacities according to the prior art first determines whether the operation mode is set to the dehumidification mode (S10).

판단 결과, 운전모드가 제습모드로 설정되어 있는 경우 용량이 큰 압축기(B) 하나만 구동하고(S11) 실내기의 풍량을 약으로 조절한다(S12).As a result, when the operation mode is set to the dehumidification mode, only one compressor B having a large capacity is driven (S11), and the air volume of the indoor unit is adjusted to about (S12).

이후, 실내 흡입온도센서를 통해 측정된 실내온도와 사용자에 의해 설정된 설정온도간의 온도차(X)를 특정온도차(N1)와 비교한다(S13). 이때, 상기 온도차(X)가 특정온도차(N1)보다 크면 반복하여 상기 온도차(X)와 특정온도차(N1)을 비교한다(S15).Thereafter, the temperature difference X between the indoor temperature measured by the indoor suction temperature sensor and the set temperature set by the user is compared with the specific temperature difference N1 (S13). At this time, if the temperature difference (X) is greater than the specific temperature difference (N1) is repeated to compare the temperature difference (X) and the specific temperature difference (N1) (S15).

그러나, 상기 온도차(X)가 특정온도차(N1)보다 작거나 같으면(S13) 압축기를 오프(off)시킨다(S14).However, if the temperature difference X is less than or equal to the specific temperature difference N1 (S13), the compressor is turned off (S14).

이후, 상기 실내온도와 설정온도 간의 온도차(X)를 특정온도차(N2)와 비교한다(S15). 이때, 상기 온도차(X)가 특정온도차(N2)보다 작으면 반복하여 상기 온도차(X)와 특정온도차(N1)을 비교한다(S15).Thereafter, the temperature difference X between the indoor temperature and the set temperature is compared with a specific temperature difference N2 (S15). At this time, if the temperature difference (X) is smaller than the specific temperature difference (N2) iteratively compares the temperature difference (X) and the specific temperature difference (N1) (S15).

그러나, 상기 온도차(X)가 특정온도차(N2)보다 크거나 같으면 실내부하가 증가되는 시점으로 판단하여 다시 압축기를 온(on)시킨다(S16).However, when the temperature difference (X) is greater than or equal to the specific temperature difference (N2), it is determined that the indoor load is increased and the compressor is turned on again (S16).

이후, 제습운전이 종료되기 전까지 상기 단계(S13~S16)를 반복 수행한다.Thereafter, the steps S13 to S16 are repeated until the dehumidification operation ends.

그러나, 이러한 종래의 제습 운전 제어방법은 제습운전 초기에 용량이 큰 압축기 한 대만으로 제습운전을 하므로 실질적인 제습기능보다는 온도차(X)에 따른 빈번한 압축기 단속운전이 행해지므로 소비전력 저감 효과를 얻지 못하는 문제점이 있었다.However, such a conventional dehumidification operation control method has a dehumidification operation with only one compressor having a large capacity at the beginning of the dehumidification operation, so that frequent compressor intermittent operation is performed according to the temperature difference (X) rather than the actual dehumidification function. There was this.

또한, 풍량을 적게 하여 실내로 토출되는 차가운 공기가 사용자에게 닿지 않도록 하기 때문에 빠른 냉방구현이 되지 않아 실내 제습운전의 효과를 볼 수도 없는 문제점이 있었다.In addition, there is a problem that can not see the effect of the indoor dehumidification operation because the cooling air discharged to the room to reduce the amount of air so as not to contact the user does not implement fast cooling.

이에 본 발명은 상기와 같은 종래의 제반 문제점을 해소하기 위해 제안된 것으로, 본 발명은 제습운전 시 실내온도와 설정온도간의 온도차에 따라 용량이 다른 두 개의 압축기를 다르게 제어함으로써 실내부하를 빠르게 경감시키면서 신속하게 제습을 할 수 있도록 한 멀티형 에어컨의 제습 운전 제어방법을 제공하는 데 그 목적이 있다.Accordingly, the present invention has been proposed to solve the conventional problems as described above, while the present invention is to quickly reduce the indoor load by controlling two compressors having different capacities according to the temperature difference between the room temperature and the set temperature during the dehumidification operation. It is an object of the present invention to provide a dehumidifying operation control method of a multi-type air conditioner that enables rapid dehumidification.

상기와 같은 목적을 달성하기 위하여 본 발명의 기술적 사상에 의한 멀티형 에어컨의 제습 운전 제어방법은, 용량이 다른 두 개의 압축기를 구비한 멀티형 에어컨의 제습 운전 제어방법에 있어서, 실내온도와 설정온도 간의 온도차를 검출하고 상기 검출된 온도차가 제1기준온도보다 큰 경우 상기 두 개의 압축기를 모두 운전하고 실내기의 풍량을 강으로 조절하는 단계와, 상기 검출된 온도차가 상기 제1기준온도보다 작거나 같고 제2기준온도보다 큰 경우 상기 두 개의 압축기 중 용량이 큰 압축기 하나만을 운전하고 상기 실내기의 풍량을 중으로 조절하는 것을 단계와, 상기 검출된 온도차가 상기 제2기준온도보다 작거나 같고 제3기준온도보다 큰 경우 상기 두 개의 압축기 중 용량이 작은 압축기 하나만을 운전하고 상기 실내기의 풍량을 약으로 조절하는 단계와, 상기 검출된 온도차가 상기 제3기준온도보다 작거나 같을 경우 상기 두 개의 압축기의 운전을 모두 정지시키고 상기 실내기의 풍량을 약으로 조절하는 단계로 상기 두 개의 압축기의 운전 및 실내기의 풍량을 다르게 제어하는 것을 특징으로 한다.Dehumidification operation control method of a multi-type air conditioner according to the technical idea of the present invention, in order to achieve the above object, in the dehumidification operation control method of a multi-type air conditioner having two compressors of different capacity, the temperature difference between the room temperature and the set temperature If the detected temperature difference is greater than the first reference temperature, operating both compressors and adjusting the air volume of the indoor unit to the strong, and the detected temperature difference is less than or equal to the first reference temperature and the second Operating only one of the two compressors having a larger capacity when the temperature is greater than the reference temperature, and adjusting the air volume of the indoor unit to the middle; and wherein the detected temperature difference is less than or equal to the second reference temperature and greater than the third reference temperature. In this case, only one compressor having a smaller capacity is operated and the air volume of the indoor unit is adjusted to about. And when the detected temperature difference is less than or equal to the third reference temperature, stopping the operation of the two compressors and adjusting the air volume of the indoor unit to about. Characterized in that differently controlled.

이하, 상기와 같은 본 발명의 기술적 사상에 따른 실시예를 첨부한 도면을 참조하여 구체적으로 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, embodiments according to the spirit of the present invention as described above will be described in detail.

도 3은 본 발명의 실시예에 따른 멀티형 에어컨의 제습 운전 제어방법을 설명하기 위한 흐름도이다. 여기서, 상기 멀티형 에어컨은 용량이 다른 두 개의 압축기(A, B)를 구비하며, 압축기(A)는 실외기 용량의 30% 수준이고, 압축기(B)는 실외기 용량의 100% 수준이다. 또한, 본 발명의 실시예에 따른 멀티형 에어컨은 스탠드형 실내기와 벽걸이형 실내기가 각 방에 따로 설치되는 2실 멀티형 에어컨이다.3 is a flowchart illustrating a dehumidification operation control method for a multi-type air conditioner according to an exemplary embodiment of the present invention. Here, the multi-type air conditioner includes two compressors A and B having different capacities, the compressor A is 30% of the capacity of the outdoor unit, and the compressor B is 100% of the capacity of the outdoor unit. In addition, the multi-type air conditioner according to an embodiment of the present invention is a two-room multi-type air conditioner in which a stand type indoor unit and a wall-mounted indoor unit are separately installed in each room.

여기에 도시한 바와 같이, 본 발명의 실시예에 따른 멀티형 에어컨의 제습 운전 제어방법은 먼저 운전모드가 제습모드로 설정되어 있는지 여부를 판단한다(S100).As shown here, the dehumidification operation control method of the multi-type air conditioner according to the embodiment of the present invention first determines whether the operation mode is set to the dehumidification mode (S100).

판단 결과, 제습모드가 설정되어 있으면 실내 흡입온도센서를 통해 실내기가 놓여진 실내의 온도를 측정한 다음, 측정된 실내온도와 설정온도 간의 온도차(X)를 검출한다(S101). 여기서, 상기 설정온도는 사용자에 의해 설정된 실내 희망온도이다.As a result, if the dehumidification mode is set, the indoor suction temperature sensor measures the temperature of the room in which the indoor unit is placed, and then detects the temperature difference (X) between the measured indoor temperature and the set temperature (S101). Here, the set temperature is the indoor desired temperature set by the user.

이후, 상기 검출된 실내온도와 설정온도 간의 온도차(X)가 제1 내지 제3기준온도에 의해 구획된 네 개의 온도 설정 구간 중 어느 구간에 포함되어 있느냐에 따라 상기 두 개의 압축기(A, B)의 운전 및 실내기의 풍량을 다르게 제어하게 된다.Thereafter, the two compressors A and B depend on which of the four temperature setting sections divided by the first to third reference temperatures is included in the temperature difference X between the detected room temperature and the set temperature. The driving and the air volume of the indoor unit will be controlled differently.

한편, 상기 실내온도와 설정온도 간의 온도차(X)가 제2기준온도(M2)보다 작거나 같고 상기 제3기준온도(M3)보다 큰 경우에는(S108) 실내 냉방부하가 경감된 것으로 판단하여 상기 두 개의 압축기(A, B) 중 용량이 작은 압축기(A) 하나만을 운전하고(S109) 실내기의 풍량을 약으로 조절한다(S110).On the other hand, if the temperature difference (X) between the room temperature and the set temperature is less than or equal to the second reference temperature (M2) and greater than the third reference temperature (M3) (S108) it is determined that the indoor cooling load is reduced Of the two compressors (A, B), only one compressor (A) having a small capacity is operated (S109), and the air volume of the indoor unit is adjusted to about (S110).

그러나, 상기 실내온도와 설정온도 간의 온도차(X)가 제3기준온도(M3)보다 작거나 같을 경우에는 상기 두 개의 압축기(A, B)의 운전을 모두 정지시키고(S111) 실내기의 풍량을 약으로 조절한다(S112).However, when the temperature difference (X) between the room temperature and the set temperature is less than or equal to the third reference temperature (M3), the operation of the two compressors (A, B) is stopped (S111) and the air volume of the indoor unit is weakened. Adjust to (S112).

이와 같이, 본 발명의 실시예에 따른 멀티형 에어컨의 제습 운전 제어방법은 제습운전 초기에 두 개의 압축기(A, B)를 모두 구동하여 급속 제습운전을 수행한 후 실내온도와 설정온도간의 온도차(X)에 따라 상기 두 개의 압축기(A, B) 중 하나만을 선택적으로 구동하여 제습 운전을 수행한다.As described above, the method for controlling the dehumidification operation of the multi-type air conditioner according to the exemplary embodiment of the present invention drives the two compressors A and B at the initial stage of the dehumidification operation to perform the rapid dehumidification operation and then the temperature difference between the room temperature and the set temperature (X). Dehumidifying operation is performed by selectively driving only one of the two compressors (A, B) according to).

따라서, 실내부하를 빠르게 경감시키면서 신속한 제습을 하여 실내온도를 쾌적하게 유지하며, 압축기의 단속 운전 횟수를 감소시켜 소비전력을 절감시킬 수 있게 된다.Therefore, while quickly reducing the indoor load to quickly dehumidify the room temperature to maintain a comfortable, it is possible to reduce the power consumption by reducing the number of intermittent operation of the compressor.
