본 발명은 공기 조화기 및 그 살균 운전 방법에 관한 것으로, 더욱 상세하게 는 실내기를 건조한 상태로 만들어 실내기의 살균을 수행하는 공기 조화기 및 그 살균 운전 방법이다. The present invention relates to an air conditioner and a sterilization operation method thereof, and more particularly, to an air conditioner for sterilizing an indoor unit by making the indoor unit dry and a sterilization operation method thereof.

일반적으로, 공기조화기의 냉방운전시 실내열교환기의 온도가 실내공기의 이슬점 온도보다 낮아져, 실내열교환기 표면에는 응축수가 맺히게 된다. 냉방운전이 끝나면, 이 응축수들은 실내기 내부에 남아 세균의 번식처가 되고, 세균의 기생으로 인하여 발효나 부패가 일어나 실내기에서 악취가 유발되는 문제점이 있었다. In general, during the cooling operation of the air conditioner, the temperature of the indoor heat exchanger is lower than the dew point temperature of the indoor air, and condensed water forms on the surface of the indoor heat exchanger. After the cooling operation, the condensate remains inside the indoor unit to become a breeding ground for bacteria, and due to the parasitics of the bacteria, there is a problem that odor is caused in the indoor unit due to fermentation or decay.

이러한 문제점을 해결하고자 종래에는 대한민국 공개특허공보 특 1998-21086(공기조화기의 살균 제어 방법)호에 개시된 바와 같이 냉방 운전이 끝나면 살균운전을 실행하기 위하여 사방밸브를 조절하여 압축기에서 토출된 고온의 냉매를 실내 열교환기로 보내고, 이 고온의 냉매에 의하여 실내 열교환기의 온도가 높아져 실내 열교환기에 맺혀 있는 응축수들이 증발되도록 하였다. 이때, 실내팬은 정지상태가 되어 실내 열교환기의 열이 실내로 토출되는 것이 차단되었다. 살균운전이 끝나면 사방밸브를 조절하여 냉방운전을 실행하고, 정지되었던 실내팬은 구동을 시작한다. In order to solve this problem, conventionally, as disclosed in Korean Patent Application Laid-Open Publication No. 1998-21086 (Sterilization Control Method of an Air Conditioner), when the cooling operation is completed, the four-way valve is adjusted to execute the sterilization operation. The refrigerant was sent to the indoor heat exchanger, and the high temperature refrigerant caused the temperature of the indoor heat exchanger to increase, causing condensate in the indoor heat exchanger to evaporate. At this time, the indoor fan is stopped and the heat of the indoor heat exchanger is blocked from being discharged to the room. After the sterilization operation, the four-way valve is adjusted to perform the cooling operation, and the stopped indoor fan starts the operation.

그러나, 이러한 종래의 공기조화기 살균방법은 실내팬을 운전하지 않기 때문에 실내기 내부에 증발된 응축수가 수증기가 되어 정체되거나, 자연 대류에 의해 상부로 빠져나가게 된다. 그리고 살균 운전이 종료되고 냉방운전이 실행되면 실내팬이 구동 될 때 실내기 내부에 정체되어 있던 다량의 수증기가 한꺼번에 토출되는 문제점이 있었다.However, since the conventional air conditioner sterilization method does not operate the indoor fan, the condensed water evaporated inside the indoor unit becomes stagnant due to water vapor or escapes to the upper part by natural convection. In addition, when the sterilization operation is terminated and the cooling operation is executed, there is a problem that a large amount of water vapor which is stagnant inside the indoor unit is discharged at the same time when the indoor fan is driven.

본 발명은 전술한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 실내기의 수분을 점진적으로 제거하는 공기 조화기 및 그 살균 운전 방법을 제공함에 있다.The present invention is to solve the above problems, an object of the present invention to provide an air conditioner and sterilization operation method for gradually removing the moisture of the indoor unit.

전술한 목적을 달성하기 위한 본 발명은 압축기를 주기적으로 운전시키면서 상기 압축기에서 토출된 고온의 냉매를 실내 열교환기로 이동시키고, 상기 압축기의 운전패턴과 반대의 운전패턴으로 실내팬을 구동시킨다. In order to achieve the above object, the present invention moves a high temperature refrigerant discharged from the compressor to an indoor heat exchanger while periodically operating a compressor, and drives an indoor fan in an operation pattern opposite to that of the compressor.

또한, 상기 압축기의 운전시간을 점진적으로 증가시킨다. In addition, the operating time of the compressor is gradually increased.

또한, 또한, 상기 압축기의 운전이 종료되면, 상기 실내팬을 일정시간 더 구동시킨다.In addition, when the operation of the compressor is terminated, the indoor fan is further driven for a predetermined time.

또한, 고온의 냉매를 토출하는 압축기와, 상기 압축기에서 토출된 고온의 냉매를 입력받는 실내 열교환기 및 상기 압축기를 주기적으로 운전시키고, 상기 압축기에서 토출된 고온의 냉매를 상기 실내 열교환기로 이동시키고, 상기 압축기의 운전패턴과 반대의 운전패턴으로 실내팬을 구동시키는 제어부를 포함한다.In addition, a compressor for discharging high-temperature refrigerant, an indoor heat exchanger receiving the high-temperature refrigerant discharged from the compressor, and periodically operating the compressor, and moving the high-temperature refrigerant discharged from the compressor to the indoor heat exchanger, And a controller for driving the indoor fan in an operation pattern opposite to the operation pattern of the compressor.

또한, 상기 제어부는 상기 압축기의 운전시간을 점진적으로 증가시킨다.In addition, the control unit gradually increases the operation time of the compressor.

또한, 상기 제어부는 상기 압축기의 운전이 종료되면, 상기 실내팬을 일정시간 더 구동시킨다.The controller may further drive the indoor fan for a predetermined time when the operation of the compressor is terminated.

이하에서는 본 발명의 바람직한 실시예를 본 도면을 참조하여 상세하게 설명하도록 한다. 도 1에 도시된 바와 같이 본 발명의 일실시예에 따른 공기 조화기는 냉매를 고온, 고압으로 압축시키는 압축기(10), 압축기(10)에서 고온, 고압으로 압 축된 냉매의 흐름방향을 결정하는 사방밸브(20), 실내열교환기(30), 실내열교환기(30)에서 열교환된 공기를 실내로 송풍하는 실내팬(40), 실외열교환기(50)에서 열교환된 공기를 외부로 송풍하는 실외팬(60), 냉매팽창장치(70)로 구성된다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, an air conditioner according to an embodiment of the present invention determines a flow direction of a refrigerant compressed at a high temperature and a high pressure in the compressor 10 and a compressor 10 that compresses the refrigerant at a high temperature and a high pressure. An indoor fan 40 for blowing air heat-exchanged by the valve 20, an indoor heat exchanger 30, and an indoor heat exchanger 30 to the room, and an outdoor fan for blowing air heat-exchanged by the outdoor heat exchanger 50 to the outside 60, a refrigerant expansion device (70).

실내열교환기(30)는 냉방운전시 낮은 온도와 압력의 액체 냉매를 입력받고, 이 액체 냉매는 주위로부터 열을 흡수하고 기체 냉매로 변환하게 된다. 또한 실내열교환기(30)는 난방운전시 높은 온도와 압력의 기체 냉매를 입력받고, 이 고온의 기체 냉매는 냉방운전의 결과로 실내열교환기(30)표면에 붙어있던 응축수를 증발시킨다. The indoor heat exchanger (30) receives a low temperature and pressure liquid refrigerant during the cooling operation, and the liquid refrigerant absorbs heat from the surroundings and converts it into a gaseous refrigerant. In addition, the indoor heat exchanger 30 receives a gas refrigerant having a high temperature and pressure during the heating operation, and the high temperature gas refrigerant evaporates the condensed water adhered to the surface of the indoor heat exchanger 30 as a result of the cooling operation.

실외열교환기(50)는 냉방운전시 높은 온도와 압력의 기체 냉매를 입력받고, 이 기체 냉매는 상온의 공기와 열교환하고 고압의 액체 냉매로 변환하게 된다. 또한 실외열교환기(50)는 난방운전시 중간 온도와 저압의 기체 냉매를 입력받고, 이 기체 냉매는 실외팬(60)에 의해 주위 공기와 열교환을 한 후 감온되어 압축기(10)으로 들어간다. The outdoor heat exchanger 50 receives a gaseous refrigerant having a high temperature and pressure during a cooling operation, and the gaseous refrigerant exchanges heat with air at room temperature and converts the liquid refrigerant into a high pressure liquid refrigerant. In addition, the outdoor heat exchanger 50 receives a gas coolant having an intermediate temperature and a low pressure during a heating operation, and the gas coolant heats down with ambient air by the outdoor fan 60 and is then cooled to enter the compressor 10.

냉매팽창장치(70)는 냉방운전시 고압의 액체 냉매를 실외열교환기(50)로부터 입력받고, 이 액체 냉매는 냉매팽창장치(70)를 지나며 낮은 온도와 압력의 액체 냉매로 만들어져 실내열교환기(30)로 입력된다. 또한 냉매팽창장치(70)는 난방운전시 실내열교환기(30)로부터 기체 냉매를 입력받고, 이 기체냉매는 중온 저압의 기체 냉매로 만들어져 실외열교환기(60)로 입력된다. The refrigerant expansion device (70) receives a high pressure liquid refrigerant from the outdoor heat exchanger (50) during the cooling operation. The liquid refrigerant passes through the refrigerant expansion device (70) and is made of a liquid refrigerant of low temperature and pressure. 30). In addition, the refrigerant expansion device (70) receives a gas refrigerant from the indoor heat exchanger (30) during the heating operation, and the gas refrigerant is made of a medium temperature low pressure gas refrigerant and input to the outdoor heat exchanger (60).

도 2는 본 발명의 일실시예에 따른 공기 조화기의 블록도로서, 압축기(10)를 구동시키는 압축기 구동부(110), 사방밸브(20)를 구동시키는 사방밸브 구동 부(120), 실내팬(40)을 구동시키는 실내팬 구동부(140), 상기 구동부들을 제어하는 제어부(100)를 구비한다. 2 is a block diagram of an air conditioner according to an embodiment of the present invention, the compressor driving unit 110 for driving the compressor 10, the four-way valve driving unit 120 for driving the four-way valve 20, the indoor fan An indoor fan driving unit 140 for driving 40 and a control unit 100 for controlling the driving units.

제어부(100)는 냉방운전이 끝나면 사방밸브 구동부(120)를 제어하여 압축기(10)에서 토출된 고온, 고압으로 압축된 냉매를 실내열교환기(30)로 흐르도록 한다. 또한, 제어부(100)는 기 설정된 압축기(10)와 실내팬(40)의 구동시간에 대한 데이터를 이용하여 압축기구동부(110) 및 실내팬구동부(140)를 제어한다. The control unit 100 controls the four-way valve driving unit 120 after the cooling operation is completed so that the refrigerant compressed by the high temperature and high pressure discharged from the compressor 10 flows to the indoor heat exchanger 30. In addition, the controller 100 controls the compressor driving unit 110 and the indoor fan driving unit 140 by using data about the driving time of the preset compressor 10 and the indoor fan 40.

이하에서는 도 3과 도 4를 참조하여 본 발명의 일실시예에 따른 히트펌프 공기 조화기의 살균 운전 방법을 설명한다.Hereinafter, a sterilization operation method of a heat pump air conditioner according to an embodiment of the present invention will be described with reference to FIGS. 3 and 4.

제어부(100)는 냉방운전이 끝나면, 실내열교환기(30)의 표면에 맺혀있는 응축수를 제거하기 위하여 사방밸브(20)를 제어하여 압축기(10)에서 나오는 고온 고압의 기체 냉매가 실내열교환기(30)로 이동하도록 한다(200). After the cooling operation is completed, the control unit 100 controls the four-way valve 20 to remove condensed water formed on the surface of the indoor heat exchanger 30 so that the high-temperature, high-pressure gas refrigerant from the compressor 10 enters the indoor heat exchanger ( 30 to go to (200).

제어부(100)는 도 4의 제1구간에 보이는 것처럼 일정시간 동안 실내팬(40)을 구동시켜, 냉방운전에 의하여 실내열교환기(30)의 표면에 맺혀있던 응축수가 실내팬의 바람에 의하여 집수부(미도시)로 떨어져 밖으로 배출되게 하고, 실내기 내부에 존재하는 수증기를 실내기 외부로 배출시킨다(210). As shown in the first section of FIG. 4, the control unit 100 drives the indoor fan 40 for a predetermined time, and the condensed water accumulated on the surface of the indoor heat exchanger 30 by the cooling operation is collected by the wind of the indoor fan. The water drops (not shown) to be discharged outward, and discharges the water vapor present in the indoor unit to the outside of the indoor unit (210).

210단계가 끝나면, 제어부(100)는 도 4의 제2구간에 보이는 것처럼 압축기(10)와 실내팬(40)을 기 설정된 시간 동안 교대로 반복 구동 시킨다. 이때, 제어부(100)는 압축기(10)의 구동 시간을 점차 증가시켜 실내열교환기(30)의 온도가 점진적으로 높아지도록 하여, 응축수가 천천히 수증기가 되도록 한다. 예를 들어, 압축기(10)를 처음 10초동안 구동하면, 다음 10초 동안은 실내팬(40)을 구동하고, 다 음에는 압축기(10)를 15초 구동하고 다음 10초 동안은 실내팬(40)을 구동한다. After the step 210 is finished, the controller 100 repeatedly drives the compressor 10 and the indoor fan 40 alternately for a preset time as shown in the second section of FIG. 4. At this time, the control unit 100 gradually increases the driving time of the compressor 10 so that the temperature of the indoor heat exchanger 30 gradually increases, so that the condensed water is slowly steamed. For example, when the compressor 10 is driven for the first 10 seconds, the indoor fan 40 is driven for the next 10 seconds, then the compressor 10 is driven for 15 seconds and the indoor fan (for the next 10 seconds). Drive 40).

실내열교환기(30)의 온도상승으로 발생된 수증기는 실내팬(30)에 의하여 천천히 실내로 배출되며, 압축기(10)의 구동이 반복될수록 실내 열교환기(30)의 온도는 점점 높아져 실내 열교환기에 남아 있는 수분이 감소하게 된다(220). The steam generated by the temperature rise of the indoor heat exchanger 30 is slowly discharged to the room by the indoor fan 30. As the driving of the compressor 10 is repeated, the temperature of the indoor heat exchanger 30 is gradually increased to the indoor heat exchanger. The remaining moisture is reduced (220).

제어부(100)는 기 설정된 압축기(10)와 실내팬(40)의 구동 시간이 경과하였는지 확인한다(230).The controller 100 checks whether the preset driving time of the compressor 10 and the indoor fan 40 has elapsed (230).

만약, 구동 시간이 경과하면 제어부(100)는 압축기(10) 및 사방밸브(20)를 오프하여 압축기(10)에서 토출되는 고온, 고압의 기체 냉매가 실내열교환기(30)로 흐르지 못하도록 한다(240).If the driving time elapses, the controller 100 turns off the compressor 10 and the four-way valve 20 to prevent the high-temperature, high-pressure gas refrigerant discharged from the compressor 10 from flowing to the indoor heat exchanger 30 ( 240).

마지막으로 제어부(100)는 도 4의 제3구간에 보이는 것처럼 실내팬(40)을 일정시간 동안 구동시켜 실내열교환기(30)의 온도를 주위 온도로 낮추고 최종적으로 수증기를 배출하여 작업을 종료한다(250). Finally, the control unit 100 drives the indoor fan 40 for a predetermined time as shown in the third section of FIG. 4 to lower the temperature of the indoor heat exchanger 30 to the ambient temperature and finally discharges water vapor to end the operation. 250.

이상에서 상세히 설명한 바와 같이, 본 발명은 살균운전시 실내 열교환기의 온도를 단계적 상승시키고, 압축기와 실내팬을 교대로 구동시켜 한번에 다량의 수증기가 발생하거나, 계속해서 더운 바람이 토출되는 것을 방지한다.  As described in detail above, the present invention increases the temperature of the indoor heat exchanger stepwise during the sterilization operation, and alternately drives the compressor and the indoor fan to prevent the generation of a large amount of water vapor at a time or to continuously discharge hot wind. .
