Description

공조기기{AIR CONDITIONER}Air Conditioning Equipment {AIR CONDITIONER}

본 발명은 냉난방 기능을 갖는 공조기기에 관한 것으로서, 더 구체적으로는, 건조 및 살균을 보다 효과적으로 수행할 수 있는 냉난방 기능을 갖는 공기조화기에 관한 것이다.The present invention relates to an air conditioner having a cooling and heating function, and more particularly, to an air conditioner having a cooling and heating function that can perform drying and sterilization more effectively.

냉난방 기능을 갖는 공조기기는 압축기와 실외 열교환기를 가지는 실외기와, 실내 열교환기를 가지는 실내기를 포함한다. 압축기에서 압축된 고온고압의 피압축 매체는 압축기의 토출구에 위치하는 사방 밸브에 의해서 선택적으로 실외 열교환기 또는 실내 열교환기로 보내진다. 냉방모드의 경우, 사방 밸브를 통과한 피압축 매체는 실외 열교환기, 실내 열교환기 및 압축기 순으로 순환한다. 그리고, 난방모드의 경우, 피압축 매체는 실내 열교환기, 실외 열교환기 및 압축기 순으로 순환한다. An air conditioner having a cooling and heating function includes an outdoor unit having a compressor and an outdoor heat exchanger, and an indoor unit having an indoor heat exchanger. The high temperature and high pressure compressed medium compressed by the compressor is selectively sent to an outdoor heat exchanger or an indoor heat exchanger by a four-way valve located at the discharge port of the compressor. In the cooling mode, the compressed medium passing through the four-way valve circulates in the order of the outdoor heat exchanger, the indoor heat exchanger, and the compressor. In the heating mode, the medium to be compressed circulates in the order of an indoor heat exchanger, an outdoor heat exchanger, and a compressor.

이러한 공조기기는, 특히 여름철과 같이 장기간 냉방모드로 운전되어야 하는 경우, 저온의 실내 열교환기에 응축된 응축수에 세균이 증식하여 실내 사용자의 건강을 해할 가능성이 높다. 그래서, 냉방운전 중에 주기적으로 혹은 사용자의 선택에 따라 살균운전이 행하여지기도 한다. Such an air conditioner is particularly likely to cause bacteria to multiply in condensed water condensed in a low-temperature indoor heat exchanger, especially when it is to be operated in a long-term cooling mode such as in summer. Therefore, the sterilization operation may be performed periodically during the cooling operation or at the user's choice.

살균운전은 냉매를 난방모드로 순환시킴으로써, 즉 압축기의 고온고압의 피압축 매체를 실내 열교환기로 직접 보내어 실내 열교환기에 응결된 응축수를 증발 건조함으로써 실내기 내부의 세균 증식을 억제하고자 하는 것이다. 이러한 살균운전에서는, 냉매에 의한 가열과 송풍팬에 의한 송풍이 동시에 행하지면서 가열과 건조가 동시에 이루어진다. Sterilization operation is to suppress the growth of bacteria inside the indoor unit by circulating the refrigerant in the heating mode, that is, by directly sending the high-temperature, high-pressure compressed medium of the compressor to the indoor heat exchanger to evaporate and dry the condensed water condensed in the indoor heat exchanger. In this sterilization operation, heating and drying are performed simultaneously while heating with a coolant and blowing with a blowing fan are performed at the same time.

그래서 살균운전 중에는 실내에 더운 열기가 공급되므로 사용자에게 불편을 준다는 문제가 있다. 또한, 송풍에 의해서도 응결수가 증발하므로, 응결수 내에 존재하는 세균이 충분한 시간 동안 가열 및 그에 의해 살균되지 아니하고 증발되는 수증기를 따라 실내에 분산될 수 있다는 문제점이 있다.Therefore, there is a problem that the user is inconvenient because hot heat is supplied to the room during sterilization operation. In addition, since the condensed water evaporates even by blowing, there is a problem that bacteria present in the condensed water can be dispersed in the room along the vapor that is evaporated without being heated and thereby sterilized for a sufficient time.

본 발명은 상술한 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 냉방과 난방 기능을 가지는 공조기기에서 내부 습기제거와 살균의 기능을 효과적으로 구현할 수 있는 공조기기를 제공하는 것이다.The present invention is to solve the above problems, an object of the present invention is to provide an air conditioner that can effectively implement the function of the internal moisture removal and sterilization in the air conditioner having the cooling and heating functions.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, an air conditioner including a compressor, an outdoor heat exchanger, an indoor heat exchanger, and an indoor unit having an indoor fan for blowing air heat exchanged with the indoor heat exchanger And a heating and cooling selection valve, a drying mode selection unit, and a control unit. The air conditioning valve selects one of the refrigerant from the outdoor heat exchanger and the indoor heat exchanger so that the refrigerant from the compressor selects one of the heating mode for circulating the outdoor heat exchanger and the indoor heat exchanger and the cooling mode for circulating the indoor heat exchanger and the outdoor heat exchanger. Optionally feed towards either. The drying mode selector may select a drying mode. When the drying mode is selected, the controller controls the air-conditioning selection valve to circulate the refrigerant in the heating mode, while the compressor operation period during which the compressor operates and the indoor fan is at least partially rested, and the indoor fan operates and the compressor is at least partial period The compressor and the indoor fan are controlled to alternately repeat the idle indoor fan operation period.

또한, 공조기기는 실내기 내부로 자외선을 조사하는 자외선 램프를 더 포함하며, 자외선 램프는 실내팬 동작기간과 적어도 일부 기간 연동하도록 제어부에 의 해서 제어되는 것이 바람직하다.In addition, the air conditioner further comprises an ultraviolet lamp for irradiating ultraviolet rays into the indoor unit, the ultraviolet lamp is preferably controlled by the controller to interlock at least a period of the indoor fan operation period.

본 발명의 냉방과 난방 기능을 가지는 공조기기는 내부 습기제거와 살균을 보다 효과적으로 수행할 수 있다. The air conditioner having the cooling and heating functions of the present invention can more effectively perform internal moisture removal and sterilization.

이하 첨부된 도면들을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명하지만, 본 발명이 실시예에 의해 제한되거나 한정되는 것은 아니다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments.

도 1은 본 발명의 일 실시예에 따른 공조기기의 구성도이며, 도 2는 본 발명의 일 실시예에 따른 공조기기의 블럭도이며, 도 3은 본 발명의 일 실시예에 따른 공조기기의 구성요소의 동작을 설명하기 위한 도면이다.1 is a block diagram of an air conditioner according to an embodiment of the present invention, FIG. 2 is a block diagram of an air conditioner according to an embodiment of the present invention, and FIG. 3 is a diagram of an air conditioner according to an embodiment of the present invention. It is a figure for demonstrating the operation | movement of a component.

도 1 내지 도 3을 참조하면, 공조기기(100)는 압축기(112)와, 실외 열교환기(114)와, 실외팬(116)을 포함하는 실외기(110)와, 실내 열교환기(124)와, 실내 열교환기(124)와 열교환된 공기를 송풍하는 실내팬(126)을 포함하는 실내기와, 냉난방선택 밸브(101)와, 건조모드 선택부(130)와, 제어부(140)와, 자외선 램프(150)를 포함한다. 1 to 3, the air conditioner 100 includes a compressor 112, an outdoor heat exchanger 114, an outdoor unit 110 including an outdoor fan 116, an indoor heat exchanger 124, , An indoor unit including an indoor fan 126 for blowing air heat-exchanged with the indoor heat exchanger 124, an air conditioner valve 101, a drying mode selector 130, a controller 140, and an ultraviolet lamp. And 150.

냉난방선택 밸브(101)는 압축기(112)를 나온 냉매를 실외 열교환기(114)와 실내 열교환기(124) 중 어느 하나를 향하여 선택적으로 공급한다.The air conditioning valve 101 selectively supplies refrigerant from the compressor 112 toward either the outdoor heat exchanger 114 or the indoor heat exchanger 124.

냉난방선택 밸브(101)에 의해서 압축기(112)를 나온 냉매가 실외 열교환기(114)로 토출되어 실내 열교환기(124), 압축기(112) 순으로 순환하는 경우에는 실내 공기를 냉각하는 냉방모드를 구현할 수 있으며, 냉매가 실내 열교환기(124)로 토출되어 실외 열교환기(114), 압축기(112) 순으로 순환하는 경우에는 실내 공기를 난방하는 난방모드를 구현할 수 있다. 실내 열교환기(124)와 실외 열교환기(114) 사이의 냉매 이동경로 상에는 전자팽창밸브(102)가 위치한다. When the refrigerant exiting the compressor 112 by the air conditioning valve 101 is discharged to the outdoor heat exchanger 114 and circulated in the order of the indoor heat exchanger 124 and the compressor 112, a cooling mode for cooling the indoor air is performed. When the refrigerant is discharged to the indoor heat exchanger 124 and circulated in the order of the outdoor heat exchanger 114 and the compressor 112, a heating mode for heating the indoor air may be implemented. The electromagnetic expansion valve 102 is positioned on the refrigerant movement path between the indoor heat exchanger 124 and the outdoor heat exchanger 114.

냉방모드를 사용할 경우에는 실내 열교환기(124)가 냉각되기 때문에 습기찬 실내 공기가 실내기(120) 내부로 유입되어 실내 열교환기(124)와 열교환될 시에 실내 열교환기(124)의 표면에 수분이 응결된다.When the cooling mode is used, the indoor heat exchanger 124 is cooled, so that damp indoor air flows into the indoor unit 120 and heats the surface of the indoor heat exchanger 124 when heat is exchanged with the indoor heat exchanger 124. It condenses.

이에 어둡고 습기찬 실내기(120) 내부에는 세균이 번식할 수 있는 적당한 환경이 되는데 이를 오랫동안 방치하고 일정 시간이 지나 공조기기(100)를 다시 사용하면 악취뿐만 아니라 실내 공기를 오염시켜 사용자의 건강에 악영향을 줄 수가 있다. The dark and damp indoor unit 120 is a suitable environment for germs to breed, but if left for a long time and the air conditioner 100 is used again after a certain time, polluting not only bad smell but also indoor air adversely affects the user's health. Can give

따라서, 건조모드를 선택하여 실내기(120) 내부의 수분을 제거하고 살균하는 것이 바람직하다. Therefore, it is preferable to remove and sterilize the water in the indoor unit 120 by selecting the drying mode.

본 발명에 따른 공조기기(100)는 건조모드를 선택할 수 있는 건조모드 선택부(130)를 포함한다. 사용자가 건조모드 선택부(130)를 통해 건조모드를 선택하면, 건조모드 선택부(130)는 제어부(140)에 건조모드를 수행하도록 신호를 전달한다. The air conditioner 100 according to the present invention includes a drying mode selector 130 capable of selecting a drying mode. When the user selects the drying mode through the drying mode selecting unit 130, the drying mode selecting unit 130 transmits a signal to the controller 140 to perform the drying mode.

실내기(120) 내부의 수분을 제거하기 위하여 건조모드가 선택된 경우, 제어부(140)는 냉매가 난방모드로 순환하도록 냉난방선택 밸브(101)를 제어하는 한편, 압축기(112)가 동작하고 실내팬(126)이 적어도 일부 기간 휴지하는 압축기(112) 동작기간(TC1~TC5)과, 실내팬(126)이 동작하고 압축기가 적어도 일부 기간 휴지하는 실내팬(126) 동작기간(Tf1~Tf5)이 교호적으로 반복되도록 압축기(112)와 실내팬(126)을 제어한다. When the drying mode is selected to remove moisture in the indoor unit 120, the controller 140 controls the air conditioning valve 101 so that the refrigerant circulates in the heating mode, while the compressor 112 operates and the indoor fan ( The operation periods TC1 to TC5 of the compressor 112 at which the 126 rests for at least one period and the operation periods Tf1 to Tf5 of the indoor fan 126 at which the indoor fan 126 operates and the compressor rests for at least part of the period are alternated. The compressor 112 and the indoor fan 126 are controlled to be repeated repeatedly.

본 실시예에서는 압축기 동작기간과 실내팬 동작기간이 서로 교호적으로 반복되되 겹치지는 않으나, 경우에 따라서 압축기 동작기간과 실내팬 동작기간은 소정기간 겹칠 수도 있다. In this embodiment, the compressor operation period and the indoor fan operation period are alternately repeated but not overlapped with each other, but in some cases, the compressor operation period and the indoor fan operation period may overlap for a predetermined period.

제어부(140)가 압축기(112)와 실내팬(126)을 교호적으로 동작하도록 제어하는 이유는 아래와 같다. The reason why the controller 140 controls the compressor 112 and the indoor fan 126 to operate alternately is as follows.

건조모드 시 실내 열교환기(124)에 수분이 존재할 경우 고온의 냉매가 가지는 열량에 의해 수분이 증발하면서 발생된 수증기가 실내팬(126)에 의해서 외부로 방출된다. When moisture is present in the indoor heat exchanger 124 in the drying mode, steam generated while the moisture evaporates by the heat amount of the high temperature refrigerant is discharged to the outside by the indoor fan 126.

그러나, 이러한 운전 패턴은 난방운전과 동일한 운전패턴이 되므로 사용자들이 의도하지 않은 더운 바람이 발생하게 된다. However, since the driving pattern becomes the same driving pattern as the heating operation, hot winds which are not intended by users are generated.

따라서, 더운 바람의 발생을 최소화하면서 실내 열교환기(124)의 온도를 목표 온도까지 상승시키기 위하여 압축기(112)를 간헐적으로 동작시키고 그 사이 사이에 실내팬(126)을 동작시키게 된다. Accordingly, the compressor 112 is intermittently operated and the indoor fan 126 is operated therebetween to raise the temperature of the indoor heat exchanger 124 to the target temperature while minimizing the generation of hot wind.

또한, 본 발명에 따른 공조기기(100)는 건조모드를 수행하면서, 동시에 실내기(120) 내부를 자외선을 이용하여 살균할 수 있도록, 자외선 램프(150)를 더 포함한다. In addition, the air conditioner 100 according to the present invention further includes an ultraviolet lamp 150 to perform the drying mode and at the same time to sterilize the inside of the indoor unit 120 using ultraviolet rays.

자외선 램프(150)는 실내팬(126) 동작기간과 적어도 일부 기간 연동하도록 제어부(140)에 의해서 제어된다. The ultraviolet lamp 150 is controlled by the controller 140 to interlock with the operation period of the indoor fan 126 at least partially.

자외선 램프(150)를 이용한 살균 효과는 습도에 영향을 받으며, 습도가 높은 경우에는 살균 효율이 떨어진다. 따라서, 실내기 내부를 건조시켜 자외선 살균을 하는 것이 바람직하다. The sterilization effect using the ultraviolet lamp 150 is affected by humidity, and when the humidity is high, the sterilization efficiency is lowered. Therefore, it is preferable to perform ultraviolet sterilization by drying the inside of the indoor unit.

또한, 자외선 램프(150)를 이용한 살균 효과는 온도에 따라서 영향을 받는데 냉방 운전 시와 같이 주위 온도 10℃ 이내의 환경에서 자외선 램프(150)를 사용하게 되면 살균 효과가 떨어진다. In addition, the sterilization effect using the ultraviolet lamp 150 is affected by the temperature, but when using the ultraviolet lamp 150 in an environment of less than 10 ℃ ambient temperature, such as during cooling operation, the sterilization effect is reduced.

따라서, 건조모드를 통해 내부 습기를 제거하고 외부로 수증기를 배출하는 동작에서 자외선 램프(150)를 연동시켜서 습기 제거와 살균 동작을 수행하는 것이 바람직하다. Therefore, in the operation of removing the internal moisture through the drying mode and discharging water vapor to the outside, it is preferable to perform the moisture removal and sterilization operation by interlocking the ultraviolet lamp 150.

종래의 공조기기에서는 자외선 살균을 냉방 운전중이나 냉방 운전을 종료하고 나서 진행하였는데, 냉방운전중에는 자외선 램프의 주위 온도가 0℃ 내지 10℃의 낮은 온도 환경에서 동작하여 살균 능력이 떨어지며, 냉방운전을 종료한 후에는 습도가 높아 효율적으로 살균이 되지 않는다.In the conventional air conditioner, UV sterilization was performed after cooling operation or after finishing cooling operation. During the cooling operation, the sterilization ability was lowered by operating in a low temperature environment of the UV lamp at 0 ° C to 10 ° C and ending the cooling operation. After that, the humidity is high and it is not efficient sterilization.

그러나, 본 발명에 따른 공조기기(100)는 건조모드 중에 살균을 병행하여 습도가 높은 경우에도 건조 살균하여 자외선 램프(150)의 살균 효율을 높이고 낮은 온도에서 자외선 램프(150)의 동작 성능이 떨어지는 문제도 건조 동작과 함께 살균 동작을 병행하여 보완하였다. However, the air conditioner 100 according to the present invention improves the sterilization efficiency of the ultraviolet lamp 150 and lowers the operating performance of the ultraviolet lamp 150 at a low temperature by performing the sterilization in the drying mode in parallel to dry sterilization even when the humidity is high. The problem was also complemented by a sterilization operation in conjunction with a drying operation.
