상기와 같은 목적을 달성하기 위한 본 고안의 바람직한 실시예를 도면을 참조하여 상세하게 설명하기로 한다.Preferred embodiments of the present invention for achieving the above object will be described in detail with reference to the drawings.
도 1을 참조하면, 본 고안에 따른 일체형 항온항습기는 수직격벽(3)에 의해 실외부(5)와 실내부(7)로 구분되고, 상기 실외부(5)에 냉매를 압축하는 압축기 (11) 및 상기 압축기(11)에 의해 압축된 기체 상태의 냉매를 응축하는 응축기(13)가 배치되고, 상기 실내부(5)에 실내부(7)로 유입되는 외기를 필터링하는 에어필터(21), 상기 응축기(13)에서 배출되는 고온고압의 냉매를 등엔탈피 팽창시키는 제 1 팽창밸브(23), 상기 상기 제 1 팽창밸브(23)에서 배출되는 냉매를 증발시키는 증발기(25), 실내 난방을 위한 히터(27), 실내 가습을 위한 가습기(29), 동절기에 건물의 실내의 온도를 낮추기 위해 사용되는 외기도입댐퍼 (31), 및 실내부(7)의 냉기 또는 온기, 습기를 건물 내부로 방출시키는 송풍팬(33)이 배치된다.Referring to FIG. 1, the integrated thermo-hygrostat according to the present invention is divided into an outdoor part 5 and an indoor part 7 by a vertical bulkhead 3, and compresses a refrigerant to the outdoor part 5. And a condenser 13 for condensing the refrigerant in a gaseous state compressed by the compressor 11, and an air filter 21 for filtering outside air introduced into the indoor unit 7 into the indoor unit 5. The first expansion valve 23 for isotropically expanding the high temperature and high pressure refrigerant discharged from the condenser 13, the evaporator 25 for evaporating the refrigerant discharged from the first expansion valve 23, the room heating Heater 27, humidifier 29 for indoor humidification, outdoor air intake damper 31 used to lower the temperature of the interior of the building in winter, and cold or warmth and humidity of the interior part 7 into the building The blowing fan 33 which discharges is arrange | positioned.
그리고, 본 고안에 따른 일체형 항온항습기는 응축기(13)와 제 1 팽창밸브(23)을 연결하는 제 1 라인(L1)에서 제 2 라인(L2)이 분기되고, 상기 제 2 라인(L2)에 제 2 전자밸브(V1), 제 2 팽창밸브(41) 및 열교환기(43)가 직렬로 연결되고, 상기 열교환기(43)에 온도센서(45)가 장착되어, 냉각수 라인(L3)으로 공급되는 냉각수와 제 2 팽창밸브(41)를 통과한 저온의 기체 냉매가 열교환기(43)에서 열교환됨으로서, 응축기(13)로 살수되는 냉각수가 저온으로 과냉각된다.In addition, the integrated thermo-hygrostat according to the present invention has a second line (L2) branched from the first line (L1) connecting the condenser (13) and the first expansion valve (23), the second line (L2) The second solenoid valve V1, the second expansion valve 41, and the heat exchanger 43 are connected in series, and the temperature sensor 45 is mounted on the heat exchanger 43, and is supplied to the cooling water line L3. The cooling water to be cooled and the low-temperature gas refrigerant passing through the second expansion valve 41 are heat-exchanged in the heat exchanger 43, whereby the cooling water sprayed by the condenser 13 is supercooled to a low temperature.
상기 제 2 팽창밸브(41)는 제 1 팽창밸브(23)와 같이 고온의 액체 냉매를 저온의 기체 냉매로 상변화시킨다. 또한, 도 2에 도시된 바와같이, 상기 제 2 팽창밸브(41) 대신에 상기 제 2 전자밸브(V2)와 상기 열교환기(43) 사이에 모세관(47)이 배치될 수 있다.Like the first expansion valve 23, the second expansion valve 41 phase-changes a high temperature liquid refrigerant into a low temperature gas refrigerant. In addition, as shown in FIG. 2, a capillary tube 47 may be disposed between the second solenoid valve V2 and the heat exchanger 43 instead of the second expansion valve 41.
미설명한 도면부호 V3은 제 3 전자밸브이고, 응축기(13)를 포함하는 실외부(5)에 별도의 온도센서(도시하지 않음)를 장착하여 온도센서에 의해 측정된 온도가 제어부(도시하지 않음)에 설정된 세팅값 이상이면, 상기 제 3 전자밸브(V3)가 자동으로 작동되도록 하거나, 또는 사용자가 임의로 개폐작동을 컨트롤할 수 있다.Reference numeral V3, which has not been described, is a third solenoid valve, and a temperature sensor (not shown) is mounted on the outdoor unit 5 including the condenser 13 so that the temperature measured by the temperature sensor is controlled. If the set value is greater than or equal to the set value, the third solenoid valve V3 may be automatically operated, or the user may arbitrarily control the opening and closing operation.
예를들어, 상기 온도센서(45)가 열교환기(43)로 공급되는 냉각수의 온도를 측정하여 냉각수의 온도가 15℃ 이상이면, 제 2 전자밸브(V2)가 개방되어 냉매가 제 2 팽창밸브(41)을 거쳐 열교환기(43)로 공급되고, 냉각수의 온도가 15℃ 미만이면 제 2 전바밸브(V2)가 닫혀 열교환기(43)로 냉매가 공급되는 것을 방지한다.For example, when the temperature sensor 45 measures the temperature of the cooling water supplied to the heat exchanger 43 and the temperature of the cooling water is 15 ° C. or more, the second solenoid valve V2 is opened to allow the refrigerant to expand into the second expansion valve. When the temperature of the cooling water is less than 15 ° C., the second electric valve V2 is closed to prevent the refrigerant from being supplied to the heat exchanger 43 via the 41.
상기와 같이 구성된 본 고안에 따른 일체형 항온항습기의 작동을 예를 들어 설명하기로 한다.The operation of the integrated thermo-hygrostat according to the present invention configured as described above will be described by way of example.
공냉식 응축기(13)는 외부의 온도에 많은 영향을 받기 때문에, 여름철에 외부의 온도가 높아 실외부(5)의 온도가 높으면 응축기(13)의 작동효율이 떨어지게 된다. 이것을 방지하기 위해 본 고안은 공냉식 응축기(13)로 과냉각된 냉각수를 살수장치(51)를 통해 살수하여 응축기(13)의 외부 온도를 낮춤으로서, 응축기(13)의 응축효율을 높이는 것이다.Since the air-cooled condenser 13 is greatly influenced by the external temperature, when the temperature of the outdoor unit 5 is high due to the high external temperature in summer, the operating efficiency of the condenser 13 is reduced. In order to prevent this, the present invention is to spray the cooling water supercooled by the air-cooled condenser 13 through the sprinkler 51 to lower the external temperature of the condenser 13, thereby increasing the condensation efficiency of the condenser 13.
즉, 응축기(13)에서 응축된 냉매가 제 1 라인(L1)을 통해 제 1 팽창밸브(23)로 공급될 때, 상기 냉매의 온도는 대략 30℃~35℃이고, 상기 제 1 라인(L1)을 통해 흐르는 액체 냉매중 일부가 제 2 라인(L2)으로 바이패싱되어 제 2 팽창밸브(41)를 통과하게 되면 상기 냉매가 제 2 팽창밸브(41)에 의해 저온(대략 0~5℃)의 기체 냉매로 상변환된다. 이와같이 저온 상태의 기체 냉매가 열교환기(43)로 공급되어 여름철 15℃~18℃ 정도의 냉각수와 열교환되므로서, 냉각수가 5℃~10℃로 과냉각된다.That is, when the refrigerant condensed in the condenser 13 is supplied to the first expansion valve 23 through the first line L1, the temperature of the refrigerant is approximately 30 ° C. to 35 ° C., and the first line L1. When a portion of the liquid refrigerant flowing through) is bypassed to the second line L2 and passes through the second expansion valve 41, the refrigerant is low temperature (approximately 0 to 5 ° C.) by the second expansion valve 41. Is phase-converted to the gas refrigerant of. In this way, the low-temperature gas refrigerant is supplied to the heat exchanger 43 and heat-exchanged with cooling water of about 15 ° C. to 18 ° C. in summer, and thus the cooling water is supercooled to 5 ° C. to 10 ° C.
이후, 열교환된 냉매는 증발기(25)와 압축기(11)를 연결하는 제 3 라인(L4)의 냉매에 합류되고, 과냉각된 냉각수는 응축기(13)로 살수된다.위에서 응축기(13)로 냉각수를 살수하는 살수장치(51)는 일반적으로 잘 알려진 물을 분사하는 노즐, 또는 스프링쿨러일 수 있다. 상기 노즐 및 스프링 쿨러의 구성은 이미 잘 알려져 있어 여기서 자세한 설명은 생략하기로 한다.Thereafter, the heat-exchanged refrigerant is joined to the refrigerant of the third line (L4) connecting the evaporator 25 and the compressor 11, and the supercooled cooling water is sprinkled by the condenser 13. The sprinkling water sprinkler 51 may be a nozzle or a sprinkler for spraying generally known water. The configuration of the nozzle and the sprinkler is already well known and detailed description thereof will be omitted.
위에서 설명한 바와같이 본 고안에 따른 일체형 항온항습기는 열교환기에 의해 과냉각된 냉각수가 응축기로 살수됨으로서 더운 여름철에 응축기의 응축효율을 높일 수 있어 냉방효율을 높일 수 있는 효과가 있다.As described above, the integrated thermo-hygrostat according to the present invention can increase the condensation efficiency of the condenser in the hot summer by spraying the coolant supercooled by the heat exchanger, thereby increasing the cooling efficiency.
