Description

암모니아흡수식 냉난방기Ammonia absorption air conditioner

본 발명은 암모니아흡수식 냉난방기에 관한 것으로서, 특히 급탕기능을 위하여 시스템에 부가되는 급탕기구조에 관한 것이다.The present invention relates to an ammonia absorption type air conditioner, and more particularly, to a hot water heater structure added to a system for a hot water supply function.

종래 암모니아 흡수식 시스템의 구성을 도 1 를 참조하여 살펴보면 흡수기(2)를 구성하는 수냉흡수기(9)및 용액냉각흡수기(10) 그리고 GAX흡수기/재생기(11)와, 상기 흡수기(2)에서 만들어진 강용액을 승압하는 용액펌프(13)와, 상기 승압된 강용액이 유입되는 재생기(1)와, 상기 재생기(1)를 가열하는 버너(8)와, 상기 재생기(1)에서 흡수기(2)로 유입되는 약용액을 팽창시키는 팽창밸브(17)와, 가열에 의해 상기 재생기(1)에서 발생된 냉매증기를 정류하는 정류기(7)와, 상기 정류된 냉매증기가 유입되는 응축기(3)와, 상기 응축기(3)에서 응축된 냉매가 유입되는 증발기(4)와, 상기 증발기(4)에서 증발된 후의 냉매를 상기 응축기(3)에서 응축된 냉매액과 열교환 시키는 냉매열교환기(12)로 구성된다.Referring to the configuration of the conventional ammonia absorption system with reference to FIG. 1, the water-cooled absorber 9, the solution-cooled absorber 10, and the GAX absorber / regenerator 11 constituting the absorber 2 and the steel made from the absorber 2 are described.

이와같이 구성되는 종래 암모니아 흡수식 냉난방기는 재생기(1)에서는 냉매인 암모니아를 분리시키는 과정이 일어나는데 버너(8)의 열을 가해주면 암모니아 농도가 강한용액(이하 강용액이라 함)으로 부터 비등점이 낮은 암모니아 냉매가 증발하며, 암모니아 농도가 약한 용액( 이하 약용액이라 함)이 얻어진다. 이 용액은 흡수기(2)로 보내지기 전에 용액가열 재생기(5)를 지나면서 재생과정의 일부를 담당한다. 이러한 과정을 통하여 재생과정에 필요한 열량이 감소하게 된다.In the conventional ammonia absorption type air conditioner configured as described above, a process of separating ammonia, which is a refrigerant, occurs in the regenerator (1). Is evaporated and a solution having a low ammonia concentration (hereinafter referred to as a medicinal solution) is obtained. This solution is part of the regeneration process as it passes through the solution heating regenerator 5 before being sent to the absorber 2. Through this process, the amount of heat required for the regeneration process is reduced.

재생기(1)에서 발생된 냉매증기에는 수분이 상당량 포함되어 있으므로 1차적으로 애너라이저(6)를 지나면서 재생기 상부로 부터 떨어지는 강용액과 직접 접촉하게 되어 냉매의 순도가 높아지며 정류기(7)에서 암모니아 농도를 보다 증가시켜 응축기(3)로 보낸다. 이 냉매증기는 응축기(3)에서 응축하여 액냉매로 되는데 이때 열량을 빼앗아 응축시키기 위해 냉각수를 사용하게 된다.Since the refrigerant vapor generated in the regenerator 1 contains a considerable amount of water, it is primarily in direct contact with the strong solution falling from the upper part of the regenerator while passing through the analyser 6, thereby increasing the purity of the refrigerant and ammonia in the rectifier 7. The concentration is further increased and sent to the condenser (3). The refrigerant vapor is condensed in the condenser (3) to be a liquid refrigerant, at which time the cooling water is used to take away the heat amount to condense.

한편, 응축기로 부터 보내져온 액냉매는 증발기(4)에서 다시 증발되어 냉매증기를 생성하는데 이때 액냉매를 증발시키게 된다. 이때 필요한 열량은 실내기(미도시)로 부터 냉방을 마치고 온도가 상승되어 들어온 냉수로 부터 공급하여 준다. 그리고 열량을 빼앗긴 냉수는 다시 온도가 떨어진 후 실내기로 다시 보내져 냉방을 수행하게 해주는 역할을 한다. 증발된 냉매증기는 냉매열교환기(12)를 거쳐 흡수기(2)로 유입되어 흡수기 상부로 부터 액막을 이루면서 떨어지는 약용액에 흡수된다. 이 흡수기중 수냉흡수기(9)는 냉각수에 의해 약용액에 흡수되면서 발생되는 흡수열을 외기로 방출하며, 용액냉각흡수기(10)는 재생기로 부터 보내져온 약용액과 열교환을 하여 재생기로 유입되는 강용의 온도를 높여주고, GAX흡수기/재생기(11)는 A 에서 분지된 용액과 약용액과의 열교환에 의해 냉매증기를 발생시켜 재생기에서의 열부하를 감소시켜준다.On the other hand, the liquid refrigerant sent from the condenser is evaporated again in the evaporator (4) to generate the refrigerant vapor, at this time to evaporate the liquid refrigerant. At this time, the required amount of heat is supplied from the cold water after the temperature is raised after cooling from the indoor unit (not shown). The cold water deprived of calories is sent back to the indoor unit after the temperature drops to perform cooling. The evaporated refrigerant vapor is introduced into the absorber (2) through the refrigerant heat exchanger (12) and absorbed by the falling chemical solution forming a liquid film from the upper part of the absorber. The water-cooled absorber (9) of the absorber releases the heat of absorption generated while being absorbed by the medicinal solution by the cooling water to the outside, and the solution cooling absorber (10) exchanges heat with the medicinal solution sent from the regenerator and flows into the regenerator. The GAX absorber / regenerator 11 reduces the heat load in the regenerator by generating a refrigerant vapor by heat exchange between the solution branched from A and the medicinal solution.

그리고 흡수기(2)에서 흡수된 강용액은 용액펌프(13)에 의해 정류기(7)로 보내어진다. 또한 냉매 열교환기(12)는 응축기로 부터 나온 액냉매와 증발기로 부터 나온 냉매증기와의 열교환을 통하여 액냉매를 증발기 내의 증발온도에 가깝게 내려주고 냉매증기의 온도는 흡수기의 포화온도 가까이 온도를 올려주어 흡수현상을 원활하게 해준다. 또한 증발기(4)에서 증발하지 않은 미소량의 냉매도 증발시켜 준다.The steel solution absorbed by the absorber 2 is sent to the rectifier 7 by the solution pump 13. In addition, the refrigerant heat exchanger 12 lowers the liquid refrigerant close to the evaporation temperature in the evaporator through heat exchange between the liquid refrigerant from the condenser and the refrigerant vapor from the evaporator, and the temperature of the refrigerant vapor increases the temperature near the saturation temperature of the absorber. The absorption phenomenon is smoothed. In addition, a small amount of refrigerant not evaporated in the evaporator 4 is evaporated.

한편, 종래의 급탕기(16)는 별도의 장치로서 부가되어 급탕시 재생기(1)에서 발생한 냉매증기는 삼방밸브(15)에서 급탕기로 유입되게 하여 급탕기내부코일을 순환하는 급탕수와 열교환을 하게된다. 그리고 급탕수에 의해 응축된 냉매액은 하부의 관을 통하여 재생기(1)로 재차 유입된다.On the other hand, the conventional hot water heater 16 is added as a separate device so that the refrigerant vapor generated in the regenerator 1 during the hot water supply flows into the hot water from the three-way valve 15 to exchange heat with the hot water circulating the coil inside the hot water heater. . The refrigerant liquid condensed by the hot water is introduced again into the regenerator 1 through the lower pipe.

이와같은 종래 소형 암모니아 흡수식 냉난방기에서는 시스템의 소형, 경량화가 필수적인데, 종래 구조는 별도의 급탕기를 사용하기 때문에 이점을 충족시켜주지 못하는 문제점이 있었다.In the conventional small ammonia absorption type air conditioner as described above, it is necessary to reduce the size and weight of the system. The conventional structure has a problem in that it cannot satisfy the advantage because a separate hot water heater is used.

본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 급탕기구조를 정류기와 함께 2중코일형태로 구성시킴으로서, 시스템의 소형 및 경량화를 구현하는데 목적이 있다.In order to solve the problems of the prior art as described above, an object of the present invention is to configure a hot water heater structure in a double coil form together with a rectifier, thereby achieving a compact and lightweight system.
