이하, 첨부도면을 참조하여 본 발명의 구성 및 작용 효과에 대해 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the configuration and effect of the present invention will be described.

첨부도면 도 1은 본 발명에 따르는 일체형 공조 시스템의 구성을 나타내는 구성도이다. 여기서, 도면부호는 종래와 동일한 구성에 대해서는 동일 부호를 그대로 사용한다.1 is a block diagram showing the configuration of an integrated air conditioning system according to the present invention. Here, the same reference numerals are used for the same configurations as in the prior art.

본 발명은 히터(10)와 이베퍼레이터(20)가 일체형으로 구성된 공조 시스템에서 에어컨 시스템 작동후 덕트(100) 내에 남아 있는 습기를 히팅 시스템으로 제거하여 습기에서 번식하는 곰팡이 등에 의해 발생되는 악취를 없앨 수 있도록 한 것이다.In the present invention, the heater 10 and the evaporator 20 are integrated in the air conditioner system to remove the odor generated by the mold and breeding in the moisture by removing the moisture remaining in the duct 100 after the air conditioning system operation in the heating system. It is to be eliminated.

이를 위한 본 발명은 상기 히터(10)와 이베퍼레이터(20)가 일체로 형성된 열교환기(40)를 포함한다. 이 열교환기(40)에는 냉각수를 공급 및 배출해 주는 냉각수 공급관(11)과 냉각수 배출관(12)이 구성되고, 또한 냉매를 공급하거나 배출해주기 위한 냉매 공급관(21)과 냉매 배출관(22)이 구비되어 있다. 특히, 이들 공급관(11,21)과 배출관(12,22)에는 각각 개폐밸브(13,14,23,24)가 갖추어져 있다.The present invention for this purpose includes a heat exchanger 40 formed integrally with the heater 10 and the evaporator 20. The heat exchanger 40 includes a coolant supply pipe 11 and a coolant discharge pipe 12 for supplying and discharging the coolant, and a coolant supply pipe 21 and a coolant discharge pipe 22 for supplying or discharging the coolant. have. In particular, these supply pipes 11 and 21 and discharge pipes 12 and 22 are provided with open / close valves 13, 14, 23 and 24, respectively.

또한, 상기 개폐밸브(13,14,23,24)들은 통상의 절환 스위치(50) 조작에 의해 제어기(60)의 제어를 받아 선택적으로 개폐되어 냉방 또는 난방 작용을 하게 된다. 즉, 상기 절환 스위치(50)를 통해 난방 시스템을 작동하게 되면 제어기(60)가 냉각수 공급관(11)과 냉각수 배출관(12)을 개구시켜 냉각수를 순환시키면서 난방 효과를 얻게 되고, 상기 절환 스위치(50)를 냉방 시트템 작동에 두게 되면 제어기(60)의 제어로 냉매 공급관(21)과 냉매 배출관(22)의 개구되어 냉방이 이루어지게 된다. 물론, 여기서, 상기 냉각수 공급/배출관(11,12)과 냉매 공급/배출관(21,22)은 어느 하나가 개구되어 작동중일때에는 다른 하나가 닫혀지도록 구성되어 있다.In addition, the on-off valves 13, 14, 23, and 24 are selectively opened and closed under the control of the controller 60 by a normal switching switch 50 to perform cooling or heating. That is, when the heating system is operated through the switching switch 50, the controller 60 opens the cooling water supply pipe 11 and the cooling water discharge pipe 12 to obtain a heating effect while circulating the cooling water, and the switching switch 50. When the cooling system is placed in the cooling system, the coolant supply pipe 21 and the coolant discharge pipe 22 are opened and controlled by the control of the controller 60. Of course, here, the cooling water supply / discharge pipes 11 and 12 and the refrigerant supply / discharge pipes 21 and 22 are configured such that the other is closed when one is opened and in operation.

이러한 상기 제어기(60)는 절환 스위치(50) 뿐만 아니라 덕트(100) 내부에 장착된 습도 센서(61)에 의해서 난방 시스템, 즉 상기 냉각수 공급관(11)과 냉각수 배출관(12)에 구성된 개폐 밸브(13,14)를 제어하게 된다.The controller 60 is an opening and closing valve configured in the heating system, that is, the cooling water supply pipe 11 and the cooling water discharge pipe 12 by the humidity sensor 61 mounted inside the duct 100 as well as the switching switch 50 ( 13, 14) will be controlled.

이를 좀 더 상세하게 설명하면, 상기 습도 센서(61)는 열교환기(40)가 장착된 덕트(100)의 내부 습도를 검출하게 되는데, 특히 에어컨 시스템이 동작한 다음에 습도가 높아 지게 되는데 이때의 습도를 검출하여 상기 제어기(60)에 신호를 보내게 된다. 상기 제어기(60)는 이러한 습도 신호를 받아 설정값 이상으로 습도가 높으면 냉각수 공급관(11)과 냉각수 배출관(12)에 구성된 개폐밸브(13,14)를 개구시켜 난방 시스템을 작동시키게 된다. 이때, 상기 제어기(60)는 종래의 공조 시스템에 구성되는 블로어(30)를 작동시키기 않게 되며, 상기 습도 센서(61)를 통해습도가 일정값 이하로 떨어졌음에 대한 신호를 받을 때까지 계속 난방 시스템을 동작시키게 된다.In more detail, the humidity sensor 61 detects the internal humidity of the duct 100 in which the heat exchanger 40 is mounted. In particular, after the air conditioner system operates, the humidity increases. Humidity is detected and sent to the controller 60. When the controller 60 receives the humidity signal and the humidity is higher than the set value, the controller 60 opens the on / off valves 13 and 14 formed in the cooling water supply pipe 11 and the cooling water discharge pipe 12 to operate the heating system. At this time, the controller 60 does not operate the blower 30 configured in the conventional air conditioning system, and continues the heating system until receiving a signal that the humidity has fallen below a predetermined value through the humidity sensor 61. Will be activated.

본 발명의 바람직한 구현예에서, 상기 제어기(60)에 미리 설정되는 습도는 곰팡이 발생이나 인체에 유해한 미생물이 번식하지 않는 정도로 설정하여 습도 센서(61)가 이 설정값보다 높으면 난방 시스템을 통해 습기를 제거함으로써 쾌적한 실내 환경을 조성할 수 있게 하는 것이 바라직하다.In a preferred embodiment of the present invention, the humidity set in advance in the controller 60 is set to such a degree that mold or harmful microorganisms do not propagate so that the humidity sensor 61 is higher than this set value, the moisture is heated through the heating system. It is desirable to be able to create a pleasant indoor environment by removing it.

이상에서와 같이 본 발명은 히터와 이베퍼레이터가 일체로 형성된 열교환기를 적용한 공조 시스템에서 냉방후 덕트 내부의 습기가 설정값 이상으로 올라가게 되면 난방 시스템을 통해 습기를 제거할 수 있게 함으로써 다음과 같은 효과를 얻게 된다.As described above, according to the present invention, when the humidity inside the duct rises above a predetermined value after cooling in an air conditioning system using a heat exchanger in which a heater and an evaporator are integrally formed, the following can be used to remove moisture through a heating system. You get an effect.
