이하, 본 발명의 저온저장고의 열교환장치를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the heat exchanger of the cold storage of the present invention will be described in detail with reference to the accompanying drawings.

도 2 및 도 3은 본 발명의 저온저장고의 열교환장치를 나타낸 단면구성도와 그 측면구성도로서, 저온저장고(10)의 실내측 벽면 하부에 냉동싸이클을 수행하는 공조기의 실내기를 구성하는 요소들을 설치할 수 있도록 저면으로 공기가 유입되는 유입구(21)와 상부에 공기가 토출되는 토출구(22)를 갖춘 열교환실(20)이 구비되어 있다.2 and 3 is a cross-sectional view and a side view showing the heat exchanger of the cold storage of the present invention, the elements constituting the indoor unit of the air conditioner to perform the refrigeration cycle in the lower wall side of the interior of the cold storage 10 The heat exchange chamber 20 is provided with an inlet 21 through which air enters the bottom surface and a discharge port 22 through which air is discharged.

상기 열교환실(20)의 내부에는 공기가 유입되는 유입구(21)로부터 증발기(30)와 응축기(31)가 중첩된 상태에서 경사지게 설치되며, 상기 열교환실(20)의 상부에 구비된 토출구(22)에는 저온저장고(10)의 벽면을 수직으로 경유하여 천정에 수평으로 배관된 덕트(40)를 통해 공기를 강제 송풍하도록 모터에 의해 구동되는 순환팬(50)이 설치되어 있다.The evaporator 30 and the condenser 31 are inclinedly installed in the heat exchange chamber 20 from an inlet 21 through which air is introduced, and the discharge port 22 provided in an upper portion of the heat exchange chamber 20. ) Is provided with a circulation fan 50 which is driven by a motor to forcibly blow air through the duct 40 horizontally piped to the ceiling via the wall surface of the cold storage 10 vertically.

상기 증발기(30)는 응축기(31)로부터 응축된 냉매가 순환되도록 연결되고, 상기 증발기와 응축기는 저온저장고(10)의 실외측 벽면에 설치한 실외기(32)에 각각 배관(33)으로 연결되어 증발기에서 열교환된 냉매를 실외기에서 압축하고 다음단계의 응축기에서 응축한 후 증발기로 순환되게 한다.The evaporator 30 is connected so that the refrigerant condensed from the condenser 31 is circulated, and the evaporator and the condenser are connected to the outdoor unit 32 installed on the outdoor wall of the cold storage 10 by pipes 33, respectively. The refrigerant exchanged in the evaporator is compressed in the outdoor unit, condensed in the condenser of the next stage, and then circulated to the evaporator.

저온저장고(10)의 천정에 수평으로 배관된 덕트(40)에는 순환팬(50)의 동작에 의해 강제로 공기를 송풍시켜 저온의 공기가 실내에 골고루 분산되도록 다수의 분기공(41)을 형성한다.A plurality of branch holes 41 are formed in the duct 40 horizontally piped to the ceiling of the cold storage 10 so as to forcibly blow air by the operation of the circulation fan 50 so that the low temperature air is evenly distributed in the room. .

상기 열교환실(20)의 저면에 구비된 유입구(21)는 벽면을 기준으로 상향으로 경사지게 개방되도록 함으로써 실내공기의 유입효율을 높일 수 있도록 한 점에서 바람직하다.The inlet 21 provided at the bottom of the heat exchange chamber 20 is preferably inclined upwardly based on the wall to increase the inflow efficiency of indoor air.

상기 유입구(21)의 경사면 하부에는 증발기(30)와 응축기(31)에 의해 포집된 제습수를 집류하는 트레이(34)와 그 트레이에 집류된 제습수를 실외로 배출시키는 드레인관(35)이 구비되어 있다.The tray 34 for collecting the dehumidified water collected by the evaporator 30 and the condenser 31 and the drain pipe 35 for discharging the dehumidified water collected in the tray to the outside are disposed below the inclined surface of the inlet 21.

따라서 상기와 같은 본 발명은 열교환실(20)의 내부에 실내공기를 저온으로 열교환하는 증발기(30)와 그 증발기에 냉매의 증발이 용이하도록 응축하여 공급하는 응축기(31)가 설치되어 실외에 설치한 실외기(32)와 함께 냉동싸이클을 수행하게 됨으로써, 열교환실(20)의 토출구(22)에 설치된 순환팬(50)이 동작되면서 공기의 순환이 이루어질 때 상기 증발기(30)에서는 실내의 더운 공기를 차갑게 하고, 응축기(31)에서는 저온의 공기 중에 포함된 습기가 포집되는 것이다.Therefore, the present invention as described above is installed in the heat exchange chamber 20, the evaporator 30 for heat-exchanging the indoor air at a low temperature and the condenser 31 for condensing and supplying the refrigerant to facilitate the evaporation of the refrigerant in the evaporator is installed outdoors As the refrigeration cycle is performed together with the outdoor unit 32, the circulation fan 50 installed in the outlet 22 of the heat exchange chamber 20 is operated to circulate the air, and the evaporator 30 provides hot air in the room. To cool, the condenser 31 is to collect the moisture contained in the low-temperature air.

즉, 실내공기가 증발기(30)를 통과할 때 열교환되어 저온으로 변화되고, 그 증발기의 냉매온도에 비해 높은 온도의 응축이 이루어지는 응축기(31)를 통과할 때 그 응축기의 표면에 결로가 유발되면서 제습이 이루어진 상태에서 순환팬(50)의 강제 송풍에 의해 덕트(40)와 그 분기공(41)을 통해 습기가 제거된 공가가 순환되므로 저온 저습 상태를 유지한다.That is, when the indoor air passes through the evaporator 30, the heat exchanger changes to a low temperature, and when condensation is induced on the surface of the condenser when passing through the condenser 31, which condenses at a higher temperature than the refrigerant temperature of the evaporator, Since dehumidification is performed, forced air of the circulation fan 50 is forced through the duct 40 and the branch hole 41 so that the cantilever is circulated to maintain a low temperature and low humidity state.

상기 증발기(30)와 응축기(31)에 의해 저온 저습 상태로 제습이 이루어질 때 발생되는 제습수는 증발기(30)와 응축기(31)의 경사진 표면을 따라 흘러서 유입구(21)의 경사면 하부에 구비된 트레이(34)에 집류되었다가 드레인관(35)을 통해 외부로 배출되는 것이다.Dehumidifying water generated when dehumidification is performed by the evaporator 30 and the condenser 31 at a low temperature and low humidity state flows along the inclined surfaces of the evaporator 30 and the condenser 31 and is provided below the inclined surface of the inlet 21. Collected in the tray 34 is discharged to the outside through the drain pipe (35).

그러므로 저온저장실의 온도를 보관하는 식품의 특성에 따라 열교환장치의 온도를 설정하면, 그 설정된 온도에 맞도록 실내공기의 열교환이 이루어지면서 저온상태를 유지함과 아울러 제습기능을 수행하게 됨으로써, 식품의 신선도를 장기간 유지할 수 있음은 물론 별도의 제습장치를 설치 및 운용하는데 따른 불편을 방지할 수 있다.Therefore, if the temperature of the heat exchanger is set according to the characteristics of the food that stores the temperature of the cold storage room, the heat exchange of the indoor air is performed according to the set temperature, thereby maintaining the low temperature and dehumidifying function, thereby maintaining the freshness of the food. It can be maintained for a long time as well as to prevent inconvenience caused by installing and operating a separate dehumidifier.

특히, 무게가 과중한 장비로 구성된 증발기(30)와 응축기(31)가 설치되는 열교환실(20)이 사람의 접근이 편리한 저온저장고(10)의 벽면 하부에 위치됨으로써, 종래에 저장고의 천정에 공조기를 설치할 때에 비해 안전사고의 위험을 방지함과 아울러 기기의 설치와 유지보수를 매우 용이하게 할 수 있는 것이다.In particular, the heat exchange chamber 20, in which the evaporator 30 and the condenser 31, which are composed of heavy equipment, is installed is located under the wall surface of the cold storage 10, which is easy for human access, and thus, the air conditioner is conventionally installed on the ceiling of the storage. It is possible to prevent the risk of safety accidents and to make the installation and maintenance of the device very easy.
