Description

수소저장합금을 이용한 냉·난방기의 열교환관{A heat exchinge pipe of a cold and heating air conditioning unit make use of hydride}Heat exchanger tube of a cold and heating air conditioning unit make use of hydride

본 발명은 수소저장합금을 이용한 냉·난방기의 열 교환관에 관한것으로, 좀더 구체적으로는 열교환관 내부에 수소저장합금을 투입 할때, 신속 정확하게 투입시킬수 있도록 하기 위한 것이다.The present invention relates to a heat exchanger tube of a cooling / heater using a hydrogen storage alloy, and more particularly, to enable a quick and accurate introduction of a hydrogen storage alloy into a heat exchanger tube.

한편, 수소저장합금에 대하여 잠깐 설명하면,On the other hand, the hydrogen storage alloy will be described briefly,

"이는 금속과 수소가 반응하여 생성된 금속 수소화물로서, 태양에너지를 이용하여 해수로 부터 얻을수 있는 수소는, 자원적 제약을 받지 않을 뿐만 아니라 환경보존의 측면에서도 문제시 되지않는 적격한 에너지 매체로서 주목되어, 안전하면서도 효율적인 저장방법과 수송방법을 검토하게 되어 1960년 최초로 네덜란드의 필립스사에서 란탄-니켈계의 수소저장합금을 개발했다."This is a metal hydride produced by the reaction of metals and hydrogen, and the hydrogen that can be obtained from seawater using solar energy is not only a resource constraint but also a suitable energy medium that does not matter in terms of environmental conservation. Attention was paid to the safe and efficient storage and transportation methods. In 1960, Philips, the Netherlands, developed the lanthanum-nickel hydrogen storage alloy.

이것은 금속과 수소가 반응하면 금속이 수소가스를 흡수하게 되어 금속 수소화물을 생성하고, 이를 다시 가열하면 수소가 방출되는데, 금속에 따라 흡수, 방출의 양과 난이도가 다르다. 그중에서도 티탄-철합금, 란탄-니켈합금, 그리고 마그네슘-니켈 합금등은 거의 실용화 단계에 있다. 금속원소 M과 기체수소분자 H2부터 수소화물(hydride) MH2가 일으키는 반응은 가역적이며, MH2생성시에는 발열, 분해시에는 흡열한다.When the metal and hydrogen react, the metal absorbs hydrogen gas to produce metal hydride, and when it is heated again, hydrogen is released. The amount and difficulty of absorption and release vary depending on the metal. Among them, titanium-iron alloys, lanthanum-nickel alloys, and magnesium-nickel alloys are in practical use. The reaction caused by the metal element M and the gaseous hydrogen molecules H 2 to hydride MH 2 is reversible, exothermic upon generation of MH 2 and endothermic upon decomposition.

금속수소화물 중에 함유된 수소원자의 밀도는 기체수소의 약 1000배이고, 일반적으로 그의 수소 평형 분배압은 낮으므로 금속수소화물로서 수소를 저장할 경우에는 1000기압의 내압분배를 필요로 하지 않는다.The density of the hydrogen atoms contained in the metal hydride is about 1000 times that of gaseous hydrogen, and in general, since the hydrogen equilibrium distribution pressure is low, when hydrogen is stored as the metal hydride, a pressure distribution of 1000 atm is not required.

또, 그 열 분해에서는 고순도의 수소가스가 얻어진다. 다음의 표에 대표적인 합금을 나타낸다.In addition, high purity hydrogen gas is obtained in the thermal decomposition. Representative alloys are shown in the following table.

예를 들면, 실온에서 수기압의 수소를 저장한 NaHi5H을 100。C부근으로 가열하면 수십기압의 수소가스를 방출한다. 즉, 기계적 콤프레샤 없이 고압 수소가스가 제조되므로 수소저장용 재료는 수소가스의 정적 콤프레샤(static compressor)라고 한다.For example, heating NaHi 5 H, which stores hydrogen at atmospheric pressure at room temperature, near 100 ° C. releases hydrogen gas at several tens of atmosphere. That is, since the high pressure hydrogen gas is produced without a mechanical compressor, the hydrogen storage material is called a static compressor of hydrogen gas.

또, 주간에 태양열로서 수소가스를 발생시켜서 탱크에 저장하여 야간에 온도가 내려갈 때, 탱크 속의 수소를 약간 가압하여 합금에 흡수시켜서 발열을 이용한 히트펌프(heat pump)도 있다. 수소엔진자동차, 태양열을 합금에 저장하는 냉·난방시스템, 핵융합에 이용하는 중 수소의 분리, 그리고 도로에 쌓인 눈을 녹이는데 응용하려는 연구도 현재 진행되고 있다."(한국 사전연구사 발행 금속공학 대사전 93p 페이지 참조)There is also a heat pump that generates hydrogen gas as solar heat during the day and stores it in a tank, and when the temperature decreases at night, the hydrogen in the tank is slightly pressurized to be absorbed by the alloy to generate heat. Research into hydrogen engine cars, cooling / heating systems that store solar heat in alloys, separation of hydrogen during nuclear fusion, and melting snow on roads is currently underway. ” Page)

또한 상기와 같은 수소저장합금을 이용하여 냉·난방기를 구성할때는 열교환기에 지그재그 방식 또는 병열식으로 설치되는 열교환관 내부에 수소저장합금 분말을 내장 설치하여야 하는데, 이때 열교환관 내부 중앙부에는 미세한 통기공을 가진 망으로된 관을 끼우고, 상기 관을 중심으로 칸막이용 링을(다수 일정간격으로)삽입하며, 상기 칸막이용링에 수소저장합금 분말 투입공을 형성하여 이곳을 통하여 수소저장합금분말을 투입하고, 이러한 열교환관을 내장 설치하여서된 열교환기를 두개(또는 두개)이상 대응 설치하여 포웨이밸브 및 펌프(또는 콤푸레샤도 이용할 수 있음)로서 번갈아 가며 압력을 가하면 수소저장합금에 저장된 수소가 빠져나가거나 흡수 되는데, 이때 수소가 빠져나간쪽은 온도가 급격히 떨어지고, 반대로 수소를 흡수한쪽은 온도가 급격히 상승하게 되며,이러한 원리를 이용한 것이 수소저장합금을 이용한 냉·난방기인 것이다In addition, when constructing a cooling / heater using the hydrogen storage alloy as described above, the hydrogen storage alloy powder should be installed inside the heat exchanger tube installed in a zigzag or parallel type in the heat exchanger. Insert a tube made of an excitation network, insert a partition ring (at a plurality of regular intervals) around the tube, form a hydrogen storage alloy powder injection hole in the partition ring, and inject hydrogen storage alloy powder therethrough. By installing two or more heat exchangers installed in such a heat exchanger tube and applying pressure alternately as a four-way valve and a pump (or a compressor can be used), hydrogen stored in the hydrogen storage alloy is released or absorbed. In this case, the temperature of the hydrogen is drastically dropped, and the side absorbing hydrogen is Degrees will be the cooling and heating using the hydrogen storage alloy it will be rapidly increased, by using the above mechanism

그런데, 위와같이 수소저장합금을 이용한 냉·난방기를 구성함에 있어서, 가장큰 문제점으로 대두되는 것은, 수소저장합금 분말을 열교환관 내에 삽입하는 것인데, 상기 종래의 구성에서는 열교환관 내부에 수소분자는 통과하면서 수소저장합금 분말은 통과되지 않도록 미세한 통기공을 가진 망으로된 관과 수소저장합금 분말의 투입이 가능하면서 수소저장합금 분말의 유동을 막기위해 수소저장합금 분말 투입공을 가진 칸막이용 링을 설치 고정시킨뒤, 칸막이용 링에 형성된 투입공을 통하여 수소저장합금 분말을 투입시키도록 되어 있고, 상기 열교환관 내부에 일정한간격을 유지하여 많은 수의 칸막이 링이 설치 고정되어 있으므로 수소저장합금 분말을 열교환관 하부까지 투입시키기에는 시간과 인력이 과다 소요됨과 동시에 적정량의 수소저장합금 분말을 정확하게 투입시키기가 매우 어려울 수 밖에 없었던 것이다.However, when constructing the air conditioner using the hydrogen storage alloy as described above, the biggest problem is to insert the hydrogen storage alloy powder into the heat exchanger tube, in the conventional configuration, the hydrogen molecules pass through the heat exchanger tube In order to prevent the hydrogen storage alloy powder from passing through, it is possible to insert a tube with a fine ventilation hole and hydrogen storage alloy powder, and to install a partition ring with hydrogen storage alloy powder injection hole to prevent the flow of hydrogen storage alloy powder. After fixing, the hydrogen storage alloy powder is introduced through the input hole formed in the partition ring, and a large number of partition rings are installed and fixed by maintaining a constant interval inside the heat exchange tube, thereby heat-exchanging the hydrogen storage alloy powder. It takes too much time and manpower to put down to the bottom of the pipe and at the same time saves the proper amount It can be very difficult to accurately put the gold powder is never outside.

따라서 위와같은 문제점에 의해 수소저장합금을 이용한 냉·난방기의 실용화가 어려운 실정이었던 것이다.Therefore, due to the above problems, the practical use of the air conditioner using the hydrogen storage alloy was difficult.

본 발명은 전술한 종래의 제반문제점을 해결하기 위해 안출된 것으로서,The present invention has been made to solve the above-mentioned conventional problems,

특히, 수소저장합금 분말을 내장하는 열교환관을 구성함에 있어서, 열교환관 내벽에 나선형 돌부를 형성하고, 열교환관 중앙부에 미세한 통기공을 가진 망으로된 관을 삽입설치하여, 나선형돌부의 끝단부가 망으로된 관의 외경부분에 밀착되게끔 구성함으로써 수소저장합금을 투입시킬때 나선형돌부에 의해 매우 신속간편하게 투입시킬수 있게끔 하려는데 그 목적이 있는 것이다.Particularly, in constructing a heat exchanger tube containing hydrogen storage alloy powder, a spiral protrusion is formed on the inner wall of the heat exchanger tube, and a tube made of a mesh having fine ventilation holes is inserted into the center of the heat exchanger tube, so that the end portion of the spiral protrusion is meshed. It is intended to be able to be injected very quickly and easily by the spiral protrusion when the hydrogen storage alloy is put in close contact with the outer diameter part of the pipe.
