본 발명은 공냉흡수식 냉난방기에 관한 것으로, 특히 운전중 생기는 결정을 감지한 후 냉매로 그 결정을 해정(解晶)시켜, 정상적인 운전을 수행할 수 있도록 한 공냉흡수식 냉난방기의 희석운전장치에 관한 것이다.The present invention relates to an air-cooled absorption air conditioner, and more particularly, to a dilution operation apparatus for an air-cooled absorption air conditioner that detects crystals generated during operation and releases the crystals with a refrigerant to perform normal operation.

일반적으로 공냉흡수식 냉난방기는 제1도에 도시되는 바와 같이, 저온, 고온열교환기(1)(2)를 거쳐 보내진 희흡수액을 가열시킴과 동시에 냉매증기를 발생시켜 농축시키므로서 진용액으로 만드는 고온재생기(3)와, 고온재생기(3)에서 발생된 냉매증기에 의해 희용액을 재가열하여 냉매증기를 방출, 농축시켜 농용액으로 만드는 저온재생기(4)와, 저온재생기(4)에서 발생된 냉매증기를 외부공기에 의해 냉각시켜 응축시킴과 동시에 저온재생기(4)에서 응축된 냉매액과 혼합되는 공냉응축기(5)와, 공냉응축기(5)로부터 보내어진 냉매를 낮은 압력에서 냉수코일(6)의 표면에 분무시켜 냉수코일(6) 내부로 흐르는 물로부터 증발잠열을 빼앗아 저온에서 증발시켜 냉수를 만드는 증발기(7)와, 증발기(7)를 낮은 압력으로 유지하여 증발이 계속하여 일어날 수 있도록 고온재생기(3)와 저온, 고온열교환기(1)(2)를 거쳐 보내어진 흡수성이 강한 농용액을 상부에서 하부로 흘러내리면서 증발기(7)에서 발생된 냉매증기를 흡수하는 공냉흡수기(8)로 구성된다.In general, an air-cooled absorption air conditioner is a high temperature regenerator that heats a rare absorbent liquid sent through a low temperature and high temperature heat exchanger (1) (2), and generates and concentrates a refrigerant vapor at the same time, thereby making it a true solution. (3) and a low temperature regenerator (4) for reheating the rare solution by the refrigerant vapor generated in the high temperature regenerator (3) to release and concentrate the refrigerant vapor to form a concentrated solution, and a refrigerant vapor generated in the low temperature regenerator (4). Is cooled by external air to condense and the air cooled condenser 5 mixed with the refrigerant liquid condensed in the low temperature regenerator 4, and the refrigerant sent from the air cooled condenser 5 at a low pressure of the cold water coil 6 The evaporator (7) and the evaporator (7) are kept at a low pressure so that the evaporation can continue to occur by removing the latent heat of evaporation from the water flowing into the cold water coil (6) by spraying the surface and evaporating at low temperature. Air-cooled absorber (8) for absorbing the refrigerant vapor generated in the evaporator (7) while flowing the absorbent strong liquid sent through the on-regenerator (3) and low temperature, high temperature heat exchanger (1) (2) from top to bottom (8) It is composed of

이와 같이 구성된 종래 공냉흡수식 냉난방기의 전체적인 작동관계를 설명하면 다음과 같다.Referring to the overall operation of the conventional air-cooled absorption air-conditioner configured as described above are as follows.

증발기(7) 내부에는 약 6-7mmHg의 저압으로 유지되고, 그 내부에는 물이 흐르는 냉수코일(6)이 설치된다. 이러한 낮은 압력을 유지하고 있는 증발기(7)의 내부에 상부로부터 냉수코일(6)의 표면에 냉수를 분무시키면 약 5℃에서 증발현상이 일어난다. 이때, 냉매가 증발하면서 냉수코일(6) 내부의 냉수(물)로부터 증발잠열을 빼앗기 때문에 냉수코일(6) 내부의 물은 약 7℃의 냉수가 되고, 이 냉수를 실내로 순환시켜 냉방을 수행하게 된다.The evaporator 7 is maintained at a low pressure of about 6-7 mmHg, and the cold water coil 6 through which water flows is installed. When cold water is sprayed onto the surface of the cold water coil 6 from the top inside the evaporator 7 maintaining such a low pressure, evaporation occurs at about 5 ° C. At this time, since the refrigerant evaporates the latent heat of evaporation from the cold water (water) in the cold water coil 6 while the refrigerant evaporates, the water inside the cold water coil 6 becomes cold water at about 7 ° C., and the cold water is circulated to perform indoor cooling. Done.

이러한 증발이 연속적으로 이루어지도록 냉매증기를 제거해야 하는데, 증발기(7)는 공냉흡수기(8)와 덕트(9)로 연결되어 있으며, 공냉흡수기(8)에는 흡수성이 강한 LiBr 수용액의 진한 용액이 상부로부터 공급되는데 증발기(7)에서 발생된 냉매증기는 덕트(9)를 통하여 공냉흡수기(8)로 유입되어 공냉흡수기(8)에서 상부로부터 공급되는 용액에 흡수된다. 이 흡수과정이 발열반응이므로 발생되는 열을 제거해야만 이 반응이 지속적으로 일어난다.The refrigerant vapor must be removed to continuously evaporate. The evaporator (7) is connected to the air cooler (8) and the duct (9), and the air absorber (8) has a concentrated solution of LiBr aqueous solution with high absorption. It is supplied from the refrigerant vapor generated in the evaporator (7) is introduced into the air cooling absorber (8) through the duct (9) is absorbed in the solution supplied from the top in the air cooling absorber (8). Since this absorption process is exothermic, this reaction continues only after removing the heat generated.

냉매를 흡수하여 농도가 묶여진 LiBr 수용액은 재생을 위하여 고온재생기(3)에서 연소열에 의해 가열되는데 비등점이 낮은 냉매증기가 먼저 비등하여 LiBr 수용액과 분리된다. 이때 발생된 냉매증기는 공냉응축기(5)에서 응축되어 재차 증발기(7)로 공급되는 일련의 순환과정을 이루게 된다.The LiBr aqueous solution in which the concentration is bound by absorbing the refrigerant is heated by combustion heat in the high temperature regenerator 3 for regeneration, and the refrigerant vapor having a low boiling point is first boiled and separated from the LiBr aqueous solution. At this time, the generated refrigerant vapor is condensed in the air-cooled condenser (5) to form a series of circulation process is supplied to the evaporator (7) again.

이러한 냉난방기 시스템에서 시스템의 효율을 높이기 위해, 고온재생기(3)에서 발생된 냉매를 재차 저온재생기(4)에서 용액가열에 이용한 후, 공냉응축기(5)로 보내어 공냉응축기(5)에서 응축과 냉매액과 혼합하여 증발기(7)로 공급된다.In order to increase the efficiency of the system in the air conditioner system, the refrigerant generated in the high temperature regenerator (3) is used again for solution heating in the low temperature regenerator (4), and then sent to the air cooling condenser (5) to condensate and refrigerant in the air cooling condenser (5). It is mixed with the liquid and supplied to the evaporator 7.

그러나, 상기에서와 같은 종래의 공냉흡수식 냉난방기는 운전중 외기온도가 높아지거나 사이클 바란스(cycle balance)가 깨졌을 경우 저온측인 저온열교환기(1)의 셸(shell)측에서 결정이 생기게 되어 정상적인 운전을 못하게 되는 문제점이 있었다.However, in the conventional air-cooled absorption air conditioner as described above, when the outside air temperature increases during operation or the cycle balance is broken, crystals are formed on the shell side of the low temperature heat exchanger 1 at the low temperature side, thereby operating normally. There was a problem that prevented.

본 발명의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해, 증발기의 냉매를 저온 열교환기로 유도시킬 수 있는 냉매공급관을 설치하여, 운전중 저온열교환기에서 생기는 결정이 냉매에 의해 해정되어 정상적인 운전을 수행할 수 있는 공냉흡수식 냉난방기의 희석운전장치를 제공하는데 있다.An object of the present invention is to provide a refrigerant supply pipe for guiding the refrigerant of the evaporator to the low temperature heat exchanger in order to solve the conventional drawback as described above, so that the crystals generated in the low temperature heat exchanger during operation are resolved by the refrigerant to operate normally. It is to provide a dilution operation device of an air-cooled absorption air-conditioner capable of performing.

이하 첨부된 도면에 따라서 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail.

본 발명도 제2도에 도시된 바와 같이, 희흡수액을 가열시킴과 동시에 냉매증기를 진용액으로 만드는 고온재생기(30)와, 고온재생기(30)에서 발생된 희용액을 재가열하여 농용액으로 만드는 저온재생기(40)와, 저온재생기(40)에서 발생된 냉매증기를 응축시키는 동시에 저온재생기(40)에서 응축된 냉매액과 혼합되는 공냉응축기(50)와, 공냉응축기(50)로부터 보내진 냉매를 낮은 압력에서 냉수코일(60)의 표면에 분무시켜 냉수를 만드는 증발기(70)와, 증발기(70)를 낮은 압력으로 유지시켜 증발이 계속하여 일어날 수 있도록 고온재생기(30)와 저온, 고온열교환기(10)(20)를 거쳐 보내어진 흡수성이 강한 농용액을 상부에서 하부로 흘러내리면서 증발기(70)에서 발생된 냉매증기를 흡수하는 공냉흡수기(80)로 구성되는 것은 종래와 같다.As shown in FIG. 2, the present invention also heats the rare absorbent liquid and simultaneously reheats the rare solution generated in the high temperature regenerator 30 to make the refrigerant vapor a true solution. The low temperature regenerator 40 and the refrigerant vapor generated in the low temperature regenerator 40 and the air cooling condenser 50 mixed with the refrigerant liquid condensed in the low temperature regenerator 40 and the refrigerant sent from the air cooling condenser 50 Evaporator 70 to make cold water by spraying the surface of the cold water coil 60 at a low pressure, and the high temperature regenerator 30 and the low temperature, high temperature heat exchanger to maintain evaporator 70 at a low pressure to continue evaporation It is the same as the conventional cooling air absorber (80) for absorbing the refrigerant vapor generated in the evaporator 70 while flowing down the absorbent strong solution sent through (10) and (20) from top to bottom.

단, 본 발명에서는 증발기의 냉매순환펌프 출구측에 연결되는 벨브와, 상기 밸브와 저온열교환기의 셸측에 연결되어 증발기의 냉매를 저온열교환기로 유도하는 냉매공급관과, 상기 저온열교환기 셸측에 결정이 생성됨에 따라 온도강하, 압력상승, 액면상승을 감지하고 이상 작동시 상기 밸브를 작동하여 정상작동 상태로 전환시키는 감지수단으로 구성됨을 그 기술적 구성상의 특징으로 한다. 이때, 밸브(90)는 제2도에서와 같이 3방향밸브를 설치한다.However, in the present invention, the valve is connected to the refrigerant circulation pump outlet side of the evaporator, the refrigerant supply pipe connected to the valve and the shell side of the low temperature heat exchanger to guide the refrigerant of the evaporator to the low temperature heat exchanger, and the low temperature heat exchanger shell side The technical feature is that it consists of a sensing means for detecting the temperature drop, the pressure rise, the liquid level rise as it is generated and to operate the valve to the normal operation state in abnormal operation. At this time, the valve 90 is provided with a three-way valve as shown in FIG.

여기서, 감지수단(110)은 저온열교환기(10)와 연결된 공냉흡수기(80)에 설치하여, 상기 저온열교환기(10)의 셸측에서 결정이 생기는 것을 감지하도록 구성함이 바람직하다.Here, the detection means 110 is preferably installed in the air-cooled absorber 80 connected to the low temperature heat exchanger 10, it is preferable to configure to detect that the crystal is generated on the shell side of the low temperature heat exchanger (10).

이때, 감지수단(110)은 온도센서, 압력센서, 수위센서를 사용하며, 상기 온도센서는 저온열교환기(10)와 공냉흡수기(81) 사이에 설치된 온도센서(110)는 온도가 정상상태시 보다 예를들어 5℃ 이상 강하가 일어나면 이를 감지하여 증발기(70)의 냉매순환펌프(71) 출구측에 설치된 밸브(90)를 오픈(open)시켜 증발기의 고온냉매를 저온열교환기(10)로 유도하여 온도를 상승시켜 결정화를 막고, 상기 압력센서는 저온열교환기(10)와 공냉흡수기(80) 사이에 설치된 압력센서(110)는 압력이 정상상태시 보다 예를 들어 5% 이상 상승하면 이를 감지하여 증발시(70)의 냉매순환펌프(71) 출구속에 설치된 밸브(90)를 오픈시켜 증발기의 고온냉매를 저온열교환기(10)로 유도하여 결정화를 막아 압력을 낮추며, 상기 수위센서는 상기 온도센서 및 압력센서와 동일하나 결정화 감지수단이 수위센서로 수위에 의해 결정화가 이루어지는 것을 감지하게 된다.At this time, the detection means 110 uses a temperature sensor, a pressure sensor, a water level sensor, the temperature sensor is installed between the low temperature heat exchanger 10 and the air cooling absorber 81 when the temperature is normal For example, when a drop of 5 ° C or more occurs, the valve 90 is installed at the outlet of the refrigerant circulation pump 71 of the evaporator 70 to detect the drop and the high temperature refrigerant of the evaporator is transferred to the low temperature heat exchanger 10. Induce the temperature increase to prevent crystallization, the pressure sensor is installed between the low temperature heat exchanger 10 and the air-cooled absorber 80, if the pressure rises, for example more than 5% than the normal state, Detects and opens the valve 90 installed in the outlet of the refrigerant circulation pump 71 at the time of evaporation to guide the high temperature refrigerant of the evaporator to the low temperature heat exchanger 10 to prevent crystallization and lower the pressure. Same as temperature sensor and pressure sensor, but detects crystallization The stage detects the crystallization by the water level with the water level sensor.

한편, 제3도는 본 발명의 다른 실시예를 나타낸 것으로, 이에 도시된 바와 같이 감지 수단(110)으로 제2도와 동일하게 온도센서, 압력센서, 수위센서를 사용하며, 상기 온도센서, 압력센서, 수위센서의 위치에 따른 일실시예의 구성을 나타내고 있는데, 이때, 밸브는 제1밸브(91)와 제2밸브(92)를 사용하며, 그 제1, 제2밸브(91)(92)에 감지수단(110)을 연결하고, 제1밸브(91)가 온이면 제2밸브(92)는 오프되고, 제1밸브(91)가 오프이며 제2밸브(92)는 온이 되도록 한다.On the other hand, Figure 3 shows another embodiment of the present invention, as shown therein using a temperature sensor, a pressure sensor, a water level sensor as shown in Figure 2 as the sensing means 110, the temperature sensor, pressure sensor, The configuration of one embodiment according to the position of the water level sensor is shown. At this time, the valve uses the first valve 91 and the second valve 92, and the first and second valves 91 and 92 are sensed. The means 110 is connected and the second valve 92 is off if the first valve 91 is on, the first valve 91 is off and the second valve 92 is on.

이와 같이 구성된 본 발명은 저온열교환기(10)에 결정이 생기면 저온열교환기(10)의 셸측과 튜브측이 모두 결정이 되고, 이에 의해 공냉흡수기(80)의 입출구에서의 용액의 출입이 불가능하여 공냉흡수기(80) 내부의 압력이 상승한다. 이때, 감지수단(110)이 공냉흡수기(80) 내의 온도, 압력 또는 수위를 감지하여 밸브(90)를 작동시키고, 이에 의해 증발기(70)내의 냉매는 저온열교환기(10)로 유도되어 결정을 용해시킨다.When the crystal is formed in the low temperature heat exchanger 10, both of the shell side and the tube side of the low temperature heat exchanger 10 are determined, and thus the solution is not allowed to enter or exit the air intake / outlet of the air cooling absorber 80. The pressure inside the air cooling absorber 80 rises. At this time, the sensing means 110 detects the temperature, pressure or water level in the air-cooled absorber 80 to operate the valve 90, whereby the refrigerant in the evaporator 70 is guided to the low temperature heat exchanger 10 to determine the crystal. Dissolve.

따라서, 본 발명에 의하면 저온열교환기(10)에서 결정이 생기기 시작하는 초기에 감지수단(110)이 이를 감지하여 증발기(70)의 냉매를 저온열교환기(10)로 바이패스시켜 결정을 해정시키기 때문에, 정상운전이 가능하고, 운전정지시 희석운전을 할 수 있어 재가동시의 정상운전까지의 도달시간을 줄일 수 있다.Therefore, according to the present invention, the detection means 110 detects this at the beginning of crystal formation in the low temperature heat exchanger 10 and bypasses the refrigerant of the evaporator 70 to the low temperature heat exchanger 10 to release the crystal. Therefore, normal operation is possible, and the dilution operation can be performed when the operation is stopped, thereby reducing the arrival time until the normal operation when restarting.

이상에서 설명한 바와 같이 본 발명은 증발기의 냉매를 저온열교환기로 유도시킬 수 있는 냉매공급관을 설치하여, 운전중 저온열교환기에서 생기는 결정이 냉매에 의해 해정되어 정상적인 운전을 수행할 수 있는 매우 유용한 발명이다.As described above, the present invention is a very useful invention in which a coolant supply pipe capable of guiding a coolant in an evaporator to a low temperature heat exchanger is installed, and crystals generated in the low temperature heat exchanger during operation are released by the coolant to perform normal operation. .
