본 고안은 흡수식 열펌프의 결정 방지장치에 관한 것으로, 흡수기에서 용액 열교환기로 들어가고 나오는 관과 발생기에서 용액 열교환기로 들어가고 나오는 관을 이중관으로 설치하고 이것을 전자변으로 적당히 개폐제어하여 농액의 결정을 방지하도록 하는것이다.The present invention relates to a device for preventing the determination of an absorption heat pump, wherein the pipe entering and exiting the solution heat exchanger from the absorber and the pipe entering and exiting the solution heat exchanger from the generator are installed as double pipes, and the opening and closing is controlled appropriately with an electronic valve to prevent the determination of the concentrate. will be.
냉매로서는 물, 흡수제로서 리듐 브로마이드를 사용하는 흡수식 열펌프는 효율적인 운행을 하기 위하여 리듐 브로마이드 수용액 농도를 높이고 있으나, 운전정지시 낮은 외기 온도에서는 흡수액의 결정되어 운전에 지장을 초래하기 쉽다. 따라서, 종래에는 이것을 방지하기 위하여 발생기로부터 고온의 농액을 흘려 희액온도를 상승시켜 동결을 방지하거나 혹은 냉매액을 농축된 흡수액에 자연 유입시키고 있으나 농흡수액이 균일하게 희석되기까지는 많은 시간이 걸려 원할한 운전을 할수 없다는 결점이 있다. 고안은 상기와 같은 결점을 해소하기 위하여 흡수식 열펌프에 있어서, 결정이 가장 일어나기 쉬운 곳에 전자변을 가지는 결정 방지회로를 설치하여 이 전자변을 적당히 개폐 제어하는 것에 의하여 농액의 결정을 방지토록 하는 것으로, 첨부도면에 의하여 상세히 설명하면 다음과 같다. ; 즉, 발생기(2), 분리기, 응축기(3), 흡수기(4) 및 용액열교환기(6)를 배관 접속시켜서 냉동 사이클과 난방 사이클을 구성하는 흡수식 열펌프에 있어서, 발생기(2)에서 용액열교환기(6)로 들어가고 나오는 관과 흡수기(4)에서 용액 열교환기(6)로 들어가고 나오는 관을 이중관으로 설치하여 흡수액이 흐르는 관 외부에 흡수식 열펌프에 열원으로 사용되는 증기나 고온수를 결정방지용 전자변(13)을 통하여 흘러 주므로써 자동적으로 결정을 방지하는 것이다.Absorption type heat pumps using water as a refrigerant and lithium bromide as an absorbent are increasing the concentration of aqueous lithium bromide solution for efficient operation. However, the absorbing liquid is easily determined at low ambient temperature when the operation is stopped. Therefore, in order to prevent this, in order to prevent the freezing by flowing a high temperature of the liquid solution from the generator to prevent the freezing, or the refrigerant liquid is naturally introduced into the concentrated absorbent liquid, it takes a long time until the concentrated absorbent liquid is uniformly diluted. The drawback is that you cannot drive. In order to solve the above-mentioned drawback, the absorption heat pump is provided with a crystal prevention circuit having an electron valve at the position where crystal is most likely to occur to prevent the determination of the agricultural liquid by appropriately opening and closing the electronic valve. Referring to the drawings in detail as follows. ; That is, in the absorption heat pump which connects the generator 2, the separator, the condenser 3, the absorber 4, and the solution heat exchanger 6 to constitute a refrigerating cycle and a heating cycle, the solution heat exchange in the generator 2 is performed. To prevent the determination of steam or hot water used as a heat source in an absorption heat pump outside the pipe through which the absorbent liquid flows by installing a pipe entering and exiting the machine (6) and the absorber (4) into the solution heat exchanger (6). By flowing through the electron valve 13, the crystal is automatically prevented.
상기에 있어서, 용액 열교환기(6) 입구에 온도조절기(15)를 설치하여 용액의 온도에 따라 결정방지용 전자변(13)을 통하여 자동적으로 결정을 방지토록 한다. 제3도는 본 고안에 사용되는 회로도로서, TC는 온도조절기, 45R : 스위치,는 릴레이, R'1, R'2는 릴레이 접점이다. 도면중 1은 열원관, 5는 증발기, 7은 용액관, 8은 냉각수관, 9는 냉수관, 10은 용액펌프, 11은 냉매펌프, 12는 열원전자변, 14는 온도조절기, 17, 18은 배수관이다.In the above, the temperature controller 15 is installed at the inlet of the solution heat exchanger 6 so as to automatically prevent crystallization through the crystal barrier electronic valve 13 according to the temperature of the solution. 3 is a circuit diagram used in the present invention, TC is a thermostat, 45R: switch, Is relay, R'1, R'2 is relay contact. 1 is a heat source tube, 5 is an evaporator, 7 is a solution tube, 8 is a cooling water pipe, 9 is a cold water pipe, 10 is a solution pump, 11 is a refrigerant pump, 12 is a heat source electron valve, 14 is a thermostat, 17, 18 is It is a drain pipe.
이와 같이 구성된 본 고안은 저압증기나 저온수의 열원에 의하여 발생기(2)가 가열되고, 흡수기(4) 및 응축기(3)에 냉각수를 순환시키는 냉각수 펌프 및 증발기(5)의 부하에 따라 냉수를 순환시키는 냉매펌프(11)가 작동된다. 이때, 발생기(2)에서 가열된 흡수액은 용액 열교환기(6)로 들어가는 한편, 발생기(2)에서 생긴 냉매증기는 응축기(3)로 들어가 역화된후 U자상 냉매관을 거쳐서 냉매분산기로부터 증발기(5) 열파이프 위에 균일하게 분사된다. 또한, 발생기(2)에서 가열된 농흡수액은 용액 열교환기(6)를 통하여 흡수액 분산기에 의하여 냉각된 기화냉매를 흡수한다. 기화냉매를 흡수한 희흡수액은 용액열교환기(6)의 외통을 통하여 발생기(2)로 보내지고, 그후로는 동일한 사이클을 반복한다. 이동안에 외기온도가 낮을 경우 흡수액의 결정이 일어나기 쉽다.According to the present invention configured as described above, the generator 2 is heated by a heat source of low pressure steam or low temperature water, and cold water is supplied according to the load of the cooling water pump and the evaporator 5 which circulates the cooling water to the absorber 4 and the condenser 3. The refrigerant pump 11 to circulate is operated. At this time, the absorbent liquid heated in the generator (2) enters the solution heat exchanger (6), while the refrigerant vapor generated in the generator (2) enters the condenser (3), is backfired, and passes through a U-shaped refrigerant pipe and passes through the U-shaped refrigerant pipe. 5) Evenly sprayed on the heat pipe. In addition, the concentrated absorbent liquid heated in the generator 2 absorbs the vaporized refrigerant cooled by the absorbent liquid disperser through the solution heat exchanger 6. The rare water absorbing the vaporized refrigerant is sent to the generator (2) through the outer cylinder of the solution heat exchanger (6), after which the same cycle is repeated. If the outside temperature is low during migration, the absorption liquid is likely to occur.
종래에는 이것을 방지하기 위하여 증발기(5)의 냉매일부를 농축된 흡수액에 자연 유입시키는 방법을 취하고 있으나 이와같이 하였을 경우 용액의 농도가 떨어져 흡수식 열펌프의 성능이 저하되고, 또 농흡수액이 균일하게 희석되기까지는 많은 시간이 걸려 원할한 운전을 할수 없다.Conventionally, in order to prevent this, a part of the refrigerant of the evaporator 5 is naturally introduced into the concentrated absorbent liquid. However, in this case, the concentration of the solution decreases, so that the performance of the absorbent heat pump is reduced, and the concentrated absorbent liquid is uniformly diluted. It takes a lot of time until you can't drive smoothly.
본 고안은 결정이 일어나기 쉬운 발생기(2)에서 용액 열교환기(6)로 들어가고 나오는 관과 흡수기(4)에서 용액 열교환기(6)로 들어가고 나오는 관을 이중관으로 설치하여 용액이 흐르는 관 외부에 흡수식 열펌프의 열원으로 사용하는 저압중기나 고온수를 결정방지용 전자변(13)을 통하여 고온의 유체를 흘러 주므로써 고온유체와 흡수액이 열교환이 되어 결정을 방지하고, 용액 열교환기(6)입구에 온도절기(15)를 설치하여 운전중에도 자동적으로 전자변(13)을 콘트롤 할수 있게 되어 흡수식 열펌프의 기능이 저하되는 일이 없다. 이상과 같이 본고안은 흡수식 열펌프에 있어서 결정이 가장 일어나기 쉬운 곳에 전자변을 설치하여 농액의 결정을 방지하고, 용액 열교환기의 입구에 설치한 온도조절기에 의하여 열펌프가 기능저하를 방지토록 하는 실용적인 고안이다.The present invention installs a tube entering and exiting the solution heat exchanger (6) from the generator (2) that is susceptible to crystallization and a tube entering and exiting the solution heat exchanger (6) from the absorber (4). The low-pressure medium or hot water used as the heat source of the heat pump flows the high-temperature fluid through the crystal-proof electronic valve 13 to prevent the crystals from being exchanged by the high-temperature fluid and the absorbent liquid. By installing the season 15, it is possible to automatically control the electronic valve 13 during operation, so that the function of the absorption heat pump is not deteriorated. As mentioned above, this paper is a practical method to prevent the determination of agricultural liquids by installing electronic valves where crystals are most likely to occur in absorption heat pumps, and to prevent the heat pumps from malfunctioning by the temperature controller installed at the inlet of the solution heat exchanger. It is devised.
