상기와 같은 창문형 에어컨에 있어서의 구성은 베이스판(50) 위에 조립되는 실내,외측 차단벽체(60,60')와, 이 실내,외측 차단벽체(60,60')의 사이에 위치되도록 베이스판(50)에 조립된 모터 브라켓에 고정되는 구동모터(80)와, 이 구동모터(80)의 구동축(81) 양단에 각각 일체로 조립되어 실내,외측 차단벽체(60,60')에 설치되는 송풍팬(90) 및 냉각팬(70)과, 실내측 차단벽체(60)에 조립되어 냉매사이클을 콘트롤하는 콘트롤 박스(도시 없음)와, 실내측 차단벽체(60)의 전방에 위치되게 조립되어 실내의 공기를 흡입함과 동시에 냉기를 배출시키는 토출구(120)와, 각 구성품을 보호하기 위하여 베이스판(50)에 조립되어지는 상부 케이스(도시 없음)로 구성되어 진다.In the window type air conditioner as described above, the base plate is disposed between the interior and exterior barrier walls 60 and 60 'assembled on the base plate 50 and the interior and exterior barrier walls 60 and 60'. The driving motor 80 is fixed to the motor bracket assembled to the 50, and is integrally assembled at both ends of the drive shaft 81 of the drive motor 80 and installed in the interior and exterior blocking walls 60, 60 '. It is assembled to the blower fan 90 and the cooling fan 70, the indoor blocking wall 60 to control the refrigerant cycle to control the refrigerant cycle and to be located in front of the indoor blocking wall 60 It is composed of a discharge port 120 for sucking air in the room and at the same time to discharge cold air, and an upper case (not shown) assembled to the base plate 50 to protect each component.

도시된 바와 같이 전,후방이 실내 및 실외로 노출되는 에어컨 몸체가 구비되며, 상기 몸체 내부는 실내차단벽체(60)와 실외차단벽체(60')에 의해 실내공간부(1)와 실외공간부(2)로 구획되고, 실내차단벽체(60)에는 중앙에서 양방향으로 회전력을 전달하는 구동모터(80)가 설치된다.As shown, the front and rear are provided with an air conditioner body exposed to the indoor and outdoor, the interior of the body by the indoor blocking wall 60 and the outdoor blocking wall (60 ') the interior space (1) and the outdoor space portion It is divided into (2), the indoor blocking wall 60 is provided with a drive motor 80 for transmitting a rotational force in both directions from the center.

또한 실내공간부(1)내에 주위의 열을 흡수하는 증발기(10)와 냉매를 고온,고압으로 압축하는 압축기(30)가 설치되며, 이 후방의 실외공간부로는 상기 압축기(30)에서 고온,고압으로 압축된 냉매를 액화시켜 상온으로 응축하는 응축기(40)가 설치되며, 상기 응축기(40)는 냉매가 흐르는 냉매관이 지그재그 형태로 다수개 배열되어 있으며, 각 냉매관의 외주연에 발생되는 열을 외부로 방열하는 방열핀(도시 없음)이 형성되어지며, 실외공간부(2)의 양측판에 실외흡입구(100)가 형성되고, 응축기(40)의 후방에 실외토출구(도시 없음)가 형성되어 진다.In addition, an evaporator 10 for absorbing ambient heat and a compressor 30 for compressing a refrigerant at high temperature and high pressure are installed in the indoor space 1, and the outdoor space portion behind the high temperature, A condenser 40 is installed to liquefy the refrigerant compressed to high pressure and condensate at room temperature.

It is done.

상기와 같이 구성되어지는 종래의 창문형 에어컨에 있어서 냉각사이클 내에서 실내온도의 강하에 의하여 증발기의 결빙문제가 발생하며 풍량에 따라 증발기를 선택할 수 없는 문제점으로 인하여 증발기의 용량이 제한적일 수 밖에 없었다.In the conventional window-type air conditioner configured as described above, the problem of freezing of the evaporator occurs due to a drop in the room temperature in the cooling cycle, and the capacity of the evaporator is limited due to the problem that the evaporator cannot be selected according to the air volume.

상기의 결빙문제를 해소하기 위한 방법으로 증발기에 더운물을 분사하여 결빙을 방지하거나, 고온의 냉매가스를 순환하도록 하여 성애를 제거하거나, 전열코일을 구성하여 전기저항에 의한 열로 동결을 방지하는 방법 등을 사용하였다.In order to solve the above-mentioned freezing problem, to prevent freezing by spraying hot water on the evaporator, to remove frost by circulating a high temperature refrigerant gas, or to prevent freezing by heat by electric resistance by forming a heat transfer coil, etc. Was used.

그러나 상기와 같은 방법에 있어서는 살수를 위한 별도의 장치가 필요하고, 고온의 냉매순환시에는 지속적인 난방이 불가능하며, 전열코일을 이용하는 경우에는 전력소모가 많은 등의 문제점이 있었다.However, in the above method, a separate device for watering is required, and continuous heating is impossible at the time of circulating high temperature refrigerant, and there is a problem such as a lot of power consumption when using a heat transfer coil.

상기와 같은 문제점을 해소하기 위하여 기 제시된 국내 실용신안공고 제91-8658호(히트펌프식 에어컨의 동결방지형 사이클)에 의하면 실외측 열교환기 시스템에 독자적인 열교환기 시스템을 병렬로 구성한 것으로 도 3에 도시되어 있다.According to Korean Utility Model Publication No. 91-8658 (Anti-freeze cycle of heat pump type air conditioner) proposed to solve the above problems, an independent heat exchanger system is configured in parallel to the outdoor heat exchanger system. Is shown.

즉, 도시한 바와 같이 4방밸브(1)를 매개로 하여 압축기(2)로부터의 냉매가스를 실내측 열교환기(3) 또는 실외측 열교환기(4)의 일측으로 토출되도록 구성된 시스템에 있어서, 상기 실외측 열교환기(4)에 서브 열교환기(5)를 병렬로 구성하고 그 입구는 압축기(2)로부터의 일부 냉매가스가 분류관(6)을 통하여 유입되도록 하는 한편, 그 출구는 솔레노이드 밸브(7)를 매개로 하여 실내측 열교환기(3) 또는 실외측 열교환기(4)의 타측과 연결되도록 하여 동절기 난방운전시 지속적인 제상 및 난방을 이루도록 하였다.That is, in the system configured to discharge the refrigerant gas from the compressor 2 to one side of the indoor side heat exchanger 3 or the outdoor side heat exchanger 4 via the four-way valve 1 as shown in the figure, The sub-heat exchanger 5 is configured in parallel to the outdoor heat exchanger 4, and its inlet allows some refrigerant gas from the compressor 2 to flow through the fractionation pipe 6, while its outlet is a solenoid valve. (7) was connected to the other side of the indoor heat exchanger (3) or the outdoor heat exchanger (4) to achieve continuous defrosting and heating during the winter heating operation.

그러나 상기와 같은 구성에 있어서는 그 구성이 복잡하고 동절기의 에어컨 동결은 방지할 수 있으나, 풍량에 따른 증발기의 선택이 불가능하여 항상 2개의 증발기를 구동하여야하므로 전력소모가 증가되는 문제점이 있었다.However, in the above configuration, the configuration is complicated and freezing of the air conditioner in the winter can be prevented. However, since the evaporator cannot be selected according to the air volume, two evaporators must be driven at all times, thereby increasing power consumption.

본 발명은 상기와 같은 종래 창문형 에어컨의 문제점을 개선하기 위한 것으로서, 주 증발기에 연장되는 보조 증발기를 장착하여 실내공기의 냉각효율을 향상하는 것은 물론 풍량에 따라 냉각능력을 조절할 수 있도록 하는 창문형 에어컨의 증발기를 제공하는 것에 그 목적이 있다.The present invention is to improve the problems of the conventional window air conditioner as described above, by installing the auxiliary evaporator extending to the main evaporator to improve the cooling efficiency of the indoor air as well as to adjust the cooling capacity according to the air volume of the window air conditioner The purpose is to provide an evaporator.

상기와 같은 목적을 달성하기 위하여 본 발명은 실내,외차단벽체로 실내,외공간부로 구획되며 흡입구를 통하여 흡입된 실내공기를 증발기를 거치면서 열교환하여 냉각된 공기를 송풍팬으로 송풍하여 토출구를 통하여 외부로 토출되도록 구성되는 창문형 에어컨의 실내기에 있어서, 상기 흡입구측에 주증발기와 연결되는 보조증발기를 설치하며, 상기 주증발기와 보조증발기는 에어컨의 풍량 선택스위치에 연계되는 조절밸브에 의하여 동시에 혹은 별도로 선택되어지는 것을 특징으로 하는 것이다.In order to achieve the above object, the present invention is partitioned into an interior and exterior space as an interior and exterior barrier wall, and the indoor air sucked through the inlet is exchanged through an evaporator to blow the cooled air to a blower fan through an outlet. In the indoor unit of the window type air conditioner configured to be discharged to the outside, the auxiliary evaporator connected to the main evaporator is installed on the inlet side, the main evaporator and the auxiliary evaporator at the same time or separately by a control valve connected to the air flow selection switch of the air conditioner To be selected.

In the outdoor unit 2, a cooling fan 70 operated by the driving motor 80 and a condenser 40 liquefied to a room temperature by liquefying a refrigerant compressed at high temperature and high pressure are assembled to the base plate 50. have.

한편 송풍팬(90)의 구동으로 실내공기를 흡입하는 흡입구(110)측에는 주증발기(10)와 보조증발기(11)가 설치되며 상기 주 및 보조증발기(10)(11)는 조절밸브로 제어되어 진다.On the other hand, the main evaporator 10 and the sub-evaporator 11 are installed at the inlet 110 side which sucks indoor air by driving the blower fan 90, and the main and sub-evaporators 10 and 11 are controlled by a control valve. Lose.

상기 주증발기(10)는 냉각사이클내 1차 냉매의 증발이 일어나며 실내공기를 흡입하여 1차로 냉각시킨다. 이때 1차 냉각으로 주증발기(10)의 용량이 작아 주증발기(10)가 결빙되는 것을 보조증발기(11)로 분산되어짐으로서 결빙을 방지하는 것이다.The main evaporator 10 is the evaporation of the primary refrigerant in the cooling cycle takes place to suck the indoor air to cool primarily. At this time, the primary evaporator 10 has a small capacity by primary cooling, and thus the main evaporator 10 is frozen to be dispersed by the auxiliary evaporator 11 to prevent freezing.

상기 보조증발기(11)는 주증발기(10)와 동시에 작동하거나 별도로 작동되는 것으로 냉매유로의 입구측 분기지점에 장착되는 조절밸브로 작동으로 제어하는 것이다.The auxiliary evaporator 11 is operated at the same time as the main evaporator 10 or separately operated to be operated by a control valve mounted at an inlet side branch point of the refrigerant passage.

도 2는 본 발명의 증발기 작동상태를 도시한 것으로서, 에어컨의 풍량선택 스위치에 연계되어 냉매분기관에 설치되어지는 제어밸브(20)에 의하여 주 및 보조증발기(10)(11)가 작동되는 것이다.2 is a view illustrating an operation of the evaporator of the present invention, in which the main and auxiliary evaporators 10 and 11 are operated by a control valve 20 installed in a refrigerant branch pipe in connection with an air volume selection switch of an air conditioner. .

즉, (a)는 풍량선택이 "강"인 경우를 도시한 것으로 이 때에는 조절밸브(20)는 양방향으로 열리게되고 주증발기(10) 및 보조증발기(11)로 동시에 냉매가 공급되어 작동되는 것이다.That is, (a) shows the case where the air flow rate selection is "strong", in which the control valve 20 is opened in both directions and the refrigerant is supplied and operated simultaneously to the main evaporator 10 and the auxiliary evaporator 11. .

(b)는 풍량선택이 "중"인 경우로서, 이 때의 조절밸브(20)는 일방향으로 열리게 되는 것으로 주증발기(10)는 열려지고 보조증발기(11)를 닫히도록 한다.(b) is a case where the air volume selection is "medium", the control valve 20 at this time is opened in one direction so that the main evaporator 10 is opened and the auxiliary evaporator 11 is closed.

(c)는 풍량선택이 "약"인 경우로서, 이 때의 조절밸브(20)는 역시 일방향으로 열리게 되는 것이나, 주증발기(10)는 닫히고 보조증발기(11)만이 열려진 상태이다.(c) is a case where the air flow rate selection is "weak", in which the control valve 20 is also opened in one direction, but the main evaporator 10 is closed and only the auxiliary evaporator 11 is opened.

이하 본 발명의 작용을 더욱 구체적으로 기술하면 다음과 같다.Hereinafter, the operation of the present invention will be described in more detail.

에어컨의 구동과 풍량스위치의 선택이되면, 구동모터(80)의 구동으로 송풍팬(90)이 회전하며 이 회전력은 실내의 더운 공기를 흡입구(110)를 통하여 에어컨의 내부로 유입되도록 한다. 이때 풍량선택에 따라 도 2에서와 같이 각각 조절밸브(20)가 양방향 혹은 일방향으로 열리게되며, 조절밸브(20)에 따라 주 및 보조증발기(10)(11)가 구동되어 흡입공기를 열교환하여 냉각된 공기를 덕트(91)로 유도하여 토출구(120)를 통하여 토출되도록 하는 것이다.When the air conditioner drive and the air volume switch is selected, the blowing fan 90 is rotated by the drive of the drive motor 80 and this rotational force allows the hot air in the room to flow into the inside of the air conditioner through the inlet 110. In this case, as shown in FIG. 2, the control valve 20 is opened in both directions or one direction according to the air volume selection, and the main and auxiliary evaporators 10 and 11 are driven according to the control valve 20 to heat-exchange the intake air.

It can prevent capacity shortage and reduce freezing.

또한 선택풍량이 "중"인 경우에는 주증발기(10)만이 작동되도록 하며, "약"인 경우에는 보조증발기(11)만이 작동되도록 조절밸브(20)를 선택하므로서 냉각에 필요한 전력소모만으로 충분한 냉각효과를 유도할 수 있는 것이다.In addition, when the selected air volume is "medium", only the main evaporator 10 is operated, and in the case of "weak", only the auxiliary evaporator 11 is selected so that the control valve 20 is selected so that only sufficient power consumption is required for cooling. It can induce an effect.

상술한 바와 같이 본 발명은 선택풍량에 따라 동시에 혹은 별도로 구동되는 주증발기와 보조증발기를 설치하여 필요한 냉각효율을 유도할 수 있으며, 주증발기의 용량부족으로 인한 결빙현상을 방지할 수 있는 효과가 있는 것이다.As described above, the present invention can induce the required cooling efficiency by installing the main evaporator and the auxiliary evaporator simultaneously or separately driven according to the selected airflow, and have an effect of preventing freezing due to insufficient capacity of the main evaporator. will be.
