본 발명은 일반 가정 및 사무실에 많이 설치되는 일체형 에어컨의 방열 제습 시스템에 관한 것으로서, 더욱 상세하게는 제습모드 시 에어컨의 증발기에서 방출되는 찬바람으로 인하여 실내온도가 저하되는 것을 방지할 수 있는 일체형 에어컨의 방열 제습 시스템에 관한 것이다.The present invention relates to a heat dissipation dehumidification system of an integrated air conditioner installed in a large number of homes and offices, and more particularly, to an integrated air conditioner which can prevent the indoor temperature from being lowered due to cold wind emitted from the evaporator of the air conditioner in the dehumidification mode. A heat dissipation dehumidification system.

에어컨은 도 1에 도시된 바와 같이 압축기(110), 응축기(120), 팽창밸브(130), 및 증발기(140)를 순환하는 냉매를 이용하여 실내의 온도를 낮춘다. 특히, 에어컨은 실내냉각과 함께 실내의 습도를 낮추는 기능을 발휘하므로 고온다습한 여름철 실내의 공기를 쾌적하게 만든다.As shown in FIG. 1, the air conditioner lowers a room temperature by using a refrigerant circulating through the compressor 110, the condenser 120, the expansion valve 130, and the evaporator 140. In particular, the air conditioner has a function of lowering the humidity of the room together with the cooling of the room, thereby making the indoor air comfortable in hot and humid summer.

그러나, 에어컨을 통한 제습방법은 장마철과 같이 실내의 온도가 높지 않은 경우에 문제가 된다. 즉, 에어컨의 제습방식은 실내의 공기를 냉각시켜 공기 중의 수증기를 응결시키는 것이므로, 실내의 온도가 높지 않으면서 실내의 습도가 높은 날에는 제습과 함께 실내를 냉각시켜 사용자에게 추위를 안겨준다.However, the dehumidification method through the air conditioner is a problem when the indoor temperature is not high, such as during the rainy season. That is, the dehumidification method of the air conditioner is to condense the water vapor in the air by cooling the air in the room, on the day when the indoor humidity is high without the room temperature is high, the room is cooled with the dehumidification gives the user a cold.

때문에 제습기능을 병행하는 에어컨은 도 1에 도시된 바와 같이 가열기(150)를 더 구비한다. 가열기(150)는 증발기(140)에서 차가워진 공기를 소정의 온도로 가열하여, 실내의 온도를 조절하는 구실을 한다.Therefore, the air conditioner in parallel with the dehumidification function is further provided with a heater 150 as shown in FIG. The heater 150 serves to control the temperature of the room by heating the air cooled in the evaporator 140 to a predetermined temperature.

그러나, 이러한 형태의 에어컨 시스템은 냉동장치와 완전히 분리된 별도의 가열수단을 더 구비해야 하므로, 장치의 단가가 높아지는 단점이 있다. 또한, 종래의 에어컨 시스템은 찬 공기를 소정의 온도로 가열하기 위해 가열기(150)에 공급되는 전류를 증대시켜야 하므로 전체 시스템의 소비전력이 증가하는 단점이 있다.However, this type of air conditioner system has to have a separate heating means that is completely separate from the refrigerating device, there is a disadvantage that the unit cost of the device increases. In addition, the conventional air conditioner system has a disadvantage in that power consumption of the entire system is increased because the current supplied to the heater 150 needs to be increased to heat cold air to a predetermined temperature.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 별도의 가열수단을 설치하지 않고도 방열·제습 기능을 발휘할 수 있는 일체형 에어컨의 방열 제습 시스템을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and an object thereof is to provide a heat dissipation dehumidification system of an integrated air conditioner capable of exhibiting a heat dissipation / dehumidification function without installing a separate heating means.

또한, 본 발명은 시스템의 전력소비량을 증대시키지 않으면서 방열·제습 기능을 원활하게 달성할 수 있는 일체형 에어컨의 방열·제습 시스템을 제공하는데 목적이 있다.In addition, an object of the present invention is to provide a heat dissipation / dehumidification system of an integrated air conditioner capable of smoothly achieving a heat dissipation / dehumidification function without increasing the power consumption of the system.

The evaporator 40 according to the present embodiment has two heat exchange parts 42 and 44. The first heat exchanger 42 and the second heat exchanger 44 are connected to the expansion valve 30 and the compressor 10 through the third pipe L3 and the fourth pipe L4. The first bypass pipe L5 and the second bypass pipe L6 are provided at the inlet and the outlet of the second heat exchange part 44. The bypass pipes L5 and L6 connect the second heat exchange part 44 and the outlet pipe (that is, the first pipe L1) of the compressor 10. The bypass pipes L5 and L6 are respectively provided with flow control valves 60 and 62 for controlling the amount of refrigerant communicated through the bypass pipes L5 and L6.

다음에서는 도 3을 토대로 본 발명의 동작원리를 설명하겠다. 도 3에서 실선으로 표시된 화살표는 냉방모드에 따른 냉매의 흐름을 나타낸 것이고, 점선으로 표시된 화살표는 제습모드에 따른 냉매의 흐름을 나타낸 것이다.Next, the operation principle of the present invention will be described based on FIG. 3. Arrows indicated by solid lines in FIG. 3 indicate the flow of the refrigerant according to the cooling mode, and arrows indicated by the dotted line indicate the flow of the refrigerant according to the dehumidification mode.

먼저, 냉방모드에 따른 에어컨 시스템의 작동과정을 살펴보겠다.First, let's look at the operation of the air conditioning system according to the cooling mode.

사용자가 에어컨의 제어부를 통해 냉방모드를 선택하면, 제1방향전환밸브(50)는 제3배관(L3)과 제2열교환부(44)가 소통되게 개방되고, 제2방향전환밸브(52)는 제4배관(L4)과 제2열교환부(44)가 소통되게 개방된다. 그리고 유량조절밸브(60, 62)는 압축기(10)에서 배출되는 냉매가 바이패스관(L5, L6)으로 빠져나가지 않도록 닫힌다.When the user selects the cooling mode through the control unit of the air conditioner, the first direction switching valve 50 is opened in communication with the third pipe (L3) and the second heat exchanger 44, the second direction switching valve 52 The fourth pipe (L4) and the second heat exchange unit 44 is open to communicate. In addition, the flow control valves 60 and 62 are closed so that the refrigerant discharged from the compressor 10 does not escape to the bypass pipes L5 and L6.

이와 같은 방향전환밸브(50, 52)와 유량조절밸브(60, 62)의 동작이 끝나면, 압축기(10)가 작동하여 냉매를 순환시킨다. 냉매는 도 3의 실선으로 표시된 화살표와 같이 압축기(10), 응축기(20), 팽창밸브(30), 제1열교환부(42) 및 제2열교환 부(44)를 순차적으로 순환하며 실내를 냉각한다.After the operation of the direction switching valve (50, 52) and the flow control valve (60, 62), the compressor (10) is operated to circulate the refrigerant. The refrigerant is circulated sequentially through the compressor 10, the condenser 20, the expansion valve 30, the first heat exchanger 42, and the second heat exchanger 44 as shown by the arrows indicated by the solid line of FIG. 3. do.

다음에서는 제습모드에 따른 에어컨 시스템의 작동과정을 살펴보겠다.Next, we will look at the operation of the air conditioning system according to the dehumidification mode.

사용자가 에어컨의 제어부를 통해 제습모드를 선택하면, 제1방향전환밸브(50)는 제2열교환부(44)와 제2바이패스관(L6)이 소통되게 개방되고, 제2방향전환밸브(52)는 제2열교환부(44)와 제1바이패스관(L5)이 소통되게 개방된다. 그리고 유량조절밸브(60, 62)는 모두 개방된다.When the user selects the dehumidification mode through the control unit of the air conditioner, the first direction switching valve 50 is opened in communication with the second heat exchanger 44 and the second bypass pipe L6, and the second direction switching valve ( 52 is open so that the second heat exchange unit 44 and the first bypass pipe L5 communicate. And flow control valve (60, 62) are all open.

위와 같은 설정이 모두 끝나면, 압축기(10)가 작동하여 냉매를 순환시킨다. 냉매는 도 3의 점선으로 표시된 화살표와 같이 압축기(10), 응축기(20), 팽창밸브(30), 제1열교환부(42)를 지나 압축기(10)로 귀환하는 냉각순환과, 압축기(10), 제1바이패스관(L1), 제2열교환부(44), 제2바이패스관(L2), 제1배관(L1)을 따라 이동하는 가열순환을 동시에 행한다.After all the above settings, the compressor 10 is operated to circulate the refrigerant. The refrigerant is returned to the compressor 10 through the compressor 10, the condenser 20, the expansion valve 30, the first heat exchanger 42, and the compressor 10, as indicated by the arrows indicated by the dotted lines of FIG. 3. ), The heating circulation moving along the first bypass pipe L1, the second heat exchange part 44, the second bypass pipe L2, and the first pipe L1 is simultaneously performed.

전자의 냉각순환은 실내의 습도를 낮추는 구실을 하고, 후자의 가열순환은 실내의 온도가 떨어지는 것을 방지하는 구실을 한다. 즉, 가열순환은 압축기(10)에 의해 가압된 고온의 냉매가 이동하는 것이므로 제2열교환부(44)의 온도를 상승시킨다. 따라서, 본 발명에 따르면 방향전환밸브(50, 52)의 개폐방향 조절을 통해 방열 및 제습 효과를 쉽게 달성할 수 있다. 아울러, 본 발명은 압축기(10)에서 압축된 고온의 냉매 일부가 제2열교환부(44)로 송출되어 제1열교환부(42)에 의해 냉각되는 냉매순환구조를 가지므로, 응축기(20)의 냉각효율을 증대시킬 수 있다.The former cooling cycle serves to lower the humidity of the room, while the latter heating cycle serves to prevent the temperature of the room from dropping. That is, the heating circulation is to move the high temperature refrigerant pressurized by the compressor 10 to increase the temperature of the second heat exchange unit (44). Therefore, according to the present invention it is possible to easily achieve the heat dissipation and dehumidification effect through the opening and closing direction control of the direction switching valve (50, 52). In addition, the present invention has a refrigerant circulation structure in which a part of the high-temperature refrigerant compressed by the compressor 10 is sent to the second heat exchange unit 44 and cooled by the first heat exchange unit 42. Cooling efficiency can be increased.

한편, 제습모드 시의 실내온도는 유량조절밸브(60, 62)의 개폐량과, 제1열교 환부(42)와 제2열교환부(44)의 열교환면적을 조절함으로써는 제어할 수 있다. 에어컨 시스템의 방열기능은 부가적인 것이므로 제1열교환부(42)이 제2열교환부(44)의 열교환면적보다 큰 것이 좋다.On the other hand, the room temperature in the dehumidification mode can be controlled by adjusting the opening and closing amounts of the flow regulating valves 60 and 62 and the heat exchange areas of the first heat exchanger 42 and the second heat exchanger 44. Since the heat dissipation function of the air conditioning system is additional, it is preferable that the first heat exchange part 42 is larger than the heat exchange area of the second heat exchange part 44.

본 발명에 따르면 별도의 가열수단을 구비하지 않고 제습모드 시 발생하는 온도저하현상을 방지할 수 있으므로, 가열수단의 설치 및 동작에 따른 제품의 단가상승과 전력소모량을 줄일 수 있다.According to the present invention, it is possible to prevent the temperature decrease occurring in the dehumidification mode without providing a separate heating means, thereby reducing the unit cost rise and power consumption of the product according to the installation and operation of the heating means.
