Description

응축열을 이용한 제습장치 {Dehumidifying device using condensation heat}Dehumidifying device using condensation heat}

본 발명은 제습장치에 관한 것으로, 보다 상세하게는 제습기 초기 동작시 일정온도 이하에서는 제습기 자체가 정상적인 동작이 되지 않는 점을 보완하기 위해 유입온도센서에서 실내온도를 감지한 후 일정 온도 이하가 되면 증발기와 응축기를 통해 제습되면서 응축열에 의하여 가열된 배출공기의 일부를 증발기 전단 실내공기 흡입구에 보내어 공기 혼합관을 통해 흡입되는 공기의 온도를 높여 원활한 제습동작이 이루어질 수 있도록 하는 제습장치에 관한 것이다.The present invention relates to a dehumidifying device, and more particularly, in order to compensate for the fact that the dehumidifier itself does not operate normally below a certain temperature during the initial operation of the dehumidifier, the inlet temperature sensor detects the room temperature and then the evaporator is below a certain temperature. The present invention relates to a dehumidifying device that transmits a part of exhaust air heated by condensation heat while dehumidifying through the condenser and to the indoor air inlet in front of the evaporator to increase the temperature of the air sucked through the air mixing pipe so that a smooth dehumidification operation can be achieved.

일반적으로 제습장치는 본체내의 하방부에 압축기와 제습수를 수용하기 위한 수용탱크를 설치하고, 상방에 상기 압축기와 동시에 냉동싸이클을 구성하여 제습기능을 발휘하는 증발기, 응축기 및 송풍기를 일렬로 배치하며 송풍기에 의해 공기 흡입구로부터 흡입된 실내공기가 증발기에 의해 냉각되어 실내공기 중의 수분이 결로되어 습기가 제거되고, 이 제습후의 차가워진 공기가 응축기의 방열에 의해 가온되어 실내온도에 맞게 데워진 건조한 제습공기를 분출구에 의해 실내로 분출되도록 구성 된다.In general, a dehumidifying device has a compressor and a receiving tank installed at the lower part of the main body to receive the dehumidifying water, and an evaporator, a condenser, and a blower performing a dehumidification function are arranged in a row by forming a refrigeration cycle at the same time as the compressor. The indoor air sucked from the air inlet by the blower is cooled by the evaporator, moisture in the indoor air is condensed to remove moisture, and the cold air after this dehumidification is heated by the heat dissipation of the condenser, and the dry dehumidified air warmed to the room temperature. It is configured to be ejected into the room by the ejection port.

이러한 구성의 제습장치는 저온의 환경 하에서 운전된 경우에 증발기의 온도는 섭씨0도시 이하로 되기 때문에 제습되어 결로된 물이 증발기에 빙결되고 이 빙결이 계속 진행되어 증발기의 상당부분이 얼어서 두껍게 덮이면 증발기의 열교환율이 악화되어 제습능력이 저하된다.When the dehumidifying device of this configuration is operated in a low-temperature environment, the temperature of the evaporator is below 0 degrees Celsius, so the water condensed by dehumidification freezes in the evaporator, and this freezing continues, and when a large portion of the evaporator freezes and is covered thickly. The heat exchange rate of the evaporator deteriorates, and the dehumidification capacity decreases.

따라서 이와 같은 경우에는 증발기의 빙결을 감지하는 빙결감지센서를 사용해서 압축기의 운전을 일시 정지시키고, 그 정지기간 중에 증발기의 근방에 배치된 제상히터를 통전시켜 제상을 행하며, 제상이 종료되면 압축기가 재운전 되도록 제습기의 운전을 제어하고 있다.Therefore, in such a case, the operation of the compressor is temporarily stopped using an ice detection sensor that detects freezing of the evaporator, and during the stop period, defrost is performed by energizing the defrost heater disposed near the evaporator. The operation of the dehumidifier is controlled so that it can be operated again.

하지만, 종래 제습장치의 경우 증발기의 빙결을 감지하고, 결빙되면 압축기의 운전을 일시 정지시키고, 그 정지기간 중에 증발기의 근방에 배치된 제상히터를 통전시켜 제상을 행한 후 재가동하거나, 히터 등을 이용하여 주변 온도를 높여야 하는 문제점이 있다.However, in the case of a conventional dehumidifying device, it detects freezing of the evaporator, temporarily stops the operation of the compressor when it freezes, and re-operates after defrosting by energizing the defrost heater disposed near the evaporator during the stop period, or using a heater. Therefore, there is a problem that the ambient temperature must be increased.

또한, 등록특허공보 제10-0191940호의 선행발명에는 이러한 문제점을 해결하기 위하여 압축기와 송풍기가 내장된 본체케이스에 실내공기의 흡입구와 분출구가 형성되고, 상기 송풍기에 의해 흡입된 실내공기를 상기 흡입구와 분출구 사이의 송풍로내에 순차적으로 배치된 증발기와 응축기를 통과시켜, 증발기에 의해 냉각 제습되고 응축기에 의해 재 가열되어 제습공기를 실내에 분출시키는 한편, 빙결감지센서에 의해 증발기의 착상을 감지하여 상기 증발기 및 응축기에 냉매를 순환시키는 압축기를 오프(OFF)시키고, 제상용 히터를 온(ON)시켜 증발기의 제상을 실시해야 하는 문제점이 있다.In addition, in the prior invention of Korean Patent Publication No. 10-0191940, in order to solve this problem, an inlet and an outlet for indoor air are formed in a main body case with a built-in compressor and a blower, and indoor air sucked by the blower is supplied with the inlet and the inlet. It passes through the evaporator and condenser sequentially arranged in the ventilation path between the ejection ports, is cooled and dehumidified by the evaporator and reheated by the condenser to eject dehumidified air into the room, while the freezing detection sensor detects the rise of the evaporator and There is a problem in that the compressor for circulating the refrigerant to the evaporator and the condenser is turned off, and the defrost heater is turned on to perform defrost of the evaporator.

또한, 공개특허공보 제10-2018-0009439호의 선행발명에는 한 쌍의 제습부를 마련하고, 각각의 제습부는 선택적으로 냉매가스의 흐름을 역류시킬 수 있게 하여 제상 운전시 고온의 액상 냉매를 증발기로 공급할 수 있도록 구성되어 한 쌍의 제습부가 마련되어 있고, 각 제습부가 별도로 가동하기 때문에 하나의 제습기가 제상 운전 모드일 때 다른 하나의 제습기가 지속적으로 제습 운전을 할 수 있고, 이들의 제상 운전과 제습 운전을 교대할 수 있게 됨으로 통상의 제습부를 하나 더 구비하게됨으로 기계자체가 복잡하고 제습효율이 낮은 문제점이 있다.In addition, in the prior invention of Korean Patent Publication No. 10-2018-0009439, a pair of dehumidifying units are provided, and each dehumidifying unit can selectively reverse the flow of refrigerant gas to supply a high-temperature liquid refrigerant to the evaporator during defrosting operation. The dehumidifying unit is configured so that a pair of dehumidifying units are provided, and each dehumidifying unit is operated separately, so when one dehumidifier is in the dehumidification operation mode, the other dehumidifier can continuously dehumidify operation, and their dehumidification operation and dehumidification operation can be performed. Since one more conventional dehumidification unit is provided because it can be replaced, the machine itself is complicated and the dehumidification efficiency is low.

이와 같이 통상의 제습장치는 제습장치에 유입되는 외부공기(A)는 제습장치의 증발기(200)를 통하여 온도가 낮아지면서 제습되지만, 제습된 공기가 응축기(100)를 통과하면서 가온되어 제습된 배출공기(B)의 온도는 유입된 외부공기(A)의 온도 보다 높게 된다.As described above, in a conventional dehumidifying device, the external air (A) flowing into the dehumidifying device is dehumidified as the temperature decreases through the evaporator 200 of the dehumidifying device, but the dehumidified air is heated while passing through the condenser 100 to discharge dehumidified. The temperature of the air (B) becomes higher than the temperature of the introduced external air (A).

본원 발명에서는 이와 같이 증발기(200)에서의 응축열을 증발기로 유입되는 외부공기(A)를 가열하는데 이용하는 제습장치이다.In the present invention, the condensation heat from the evaporator 200 is used to heat the external air (A) flowing into the evaporator.

본원 발명의 제습장치는 상기 증발기(200)로 유입되는 외부공기(A)가 일정한 온도(18 도) 이하인 경우 액상의 냉매를 저온, 저압의 기체로 변환시키는 증발기(200)의 표면에는 결상이 되는 형상을 미연에 방지하기 위하여 증발기(200)에서 제습된 공기가 응축기(100)를 통과하면서 가온된 배출공기(B)를 송풍장치(300)로 실내 배출구(400)로 배출하는 제1차유로(500)에서, 상기 제1차유로(500)와 외부공기(A)가 흡입되는 증발기 입구(600)를 연결하는 2차유로(700)를 형성하여 구비하고 있다.In the dehumidifying device of the present invention, when the external air (A) flowing into the evaporator 200 is below a certain temperature (18 degrees), a liquid phase is formed on the surface of the evaporator 200 that converts a liquid refrigerant into a low-temperature, low-pressure gas. In order to prevent the shape in advance, the air dehumidified by the evaporator 200 passes through the condenser 100 and the heated exhaust air B is discharged to the indoor outlet 400 through the blower 300. In 500), a secondary flow path 700 connecting the first flow path 500 and the evaporator inlet 600 through which external air A is sucked is formed and provided.

Looking at the operation of this configuration, when the external air (A) sucked into the evaporator 200 is below a certain temperature (normally 18 degrees C), it is discharged to the first flow path 500 through the secondary flow path 700. A part of the heated exhaust air (B) being heated is transferred to the inlet 600 of the evaporator, so that the external air (A) and the exhaust air (B) are mixed, thereby increasing the temperature of the inlet air flowing into the evaporator 200 It prevents the formation of the surface of the evaporator 200 by shikim, and enables smooth dehumidification.
