본 발명은 암모니아 흡수식 열교환기에 관한 것으로서, 특히 급탕의 온수를 공급받고자 할 때 시스템이 정상운전에 도달할때까지 사용자가 기다려야 하는 불편을 해결하고자 하는 급탕용 온수공급장치에 관한 것이다.The present invention relates to an ammonia absorption heat exchanger, and more particularly to a hot water supply device for hot water supply to solve the inconvenience that the user has to wait until the system reaches a normal operation when the hot water of the hot water supply.

종래 암모니아 흡수식 시스템의 구성을 도 1 를 참조하여 살펴보면 흡수기(9)를 구성하는 수냉흡수기(7)와 용액냉각흡수기(8)와, 상기 흡수기(9)에서 만들어진 강용액을 승압하는 용액펌프(10)와, 상기 승압된 강용액이 유입되는 재생기(1)와, 상기 재생기(1)를 가열하는 버너(11)와, 상기 재생기(1)에서 흡수기(9)로 유입되는 약용액을 팽창시키는 팽창밸브(13)와, 가열에 의해 상기 재생기(1)에서 발생된 냉매증기를 정류하는 정류기(3)와, 상기 정류된 냉매증기가 유입되는 응축기(4)와, 상기 응축기(4)에서 응축된 냉매가 유입되는 증발기(6)와, 상기 증발기(6)에서 증발된 후의 냉매를 상기 응축기(4)에서 응축된 냉매액과 열교환 시키는 냉각기(5)로 구성된다.Referring to the configuration of the conventional ammonia absorption system with reference to FIG. 1, the water-cooled absorber 7 and the solution-cooled absorber 8 constituting the absorber 9, and a solution pump 10 for boosting the steel solution produced in the absorber 9. ), A regenerator (1) into which the boosted strong solution flows, a burner (11) for heating the regenerator (1), and an expansion for expanding the chemical solution flowing into the absorber (9) from the regenerator (1). A valve 13, a rectifier 3 for rectifying the refrigerant vapor generated in the regenerator 1 by heating, a condenser 4 into which the rectified refrigerant vapor is introduced, and condensed in the condenser 4 An evaporator 6 into which the refrigerant flows, and a cooler 5 for exchanging the refrigerant after evaporating in the evaporator 6 with the refrigerant liquid condensed in the condenser 4.

도면중 미설명 부호 2 는 애널라이저를 나타낸다.In the figure, reference numeral 2 denotes an analyzer.

이와같이 구성되는 종래 흡수식 시스템은 흡수기(9)에서 계속적인 흡수작용으로 인해 암모니아의 농도가 진한 강용액으로 변하며 이 강용액은 용액펌프(10)에 의해 재생기(1)로 압송된다. 이 강용액은 재생기(1)의 연소부인 버너(11)로 가열되어 암모니아냉매가 증발됨으로서 약용액으로 변하며 저압부의 흡수기(9) 상부로 약용액유로(12)상에 있는 팽창밸브(13)를 거쳐 유입된다. 한편 증발된 암모니아 냉매증기는 애널라이저(2)와 정류기(3)를 거치면서 보다 순도가 높고 온도가 강하된 암모니아 증기로 되어 냉매증기유로(15)를 거쳐 응축기(4)로 들어가 냉각수 등의 중간매체(20)에 의해 냉각되어 액체상태의 냉매(16)로 변화한다. 암모니아 액냉매는 냉각기(5)의 외부관속을 흐르며 이때 내부관 속을 흐르는 저온의 증기냉매 사이에 상호 열교환이 이루어져 액냉매는 과냉되고 증기냉매는 과열됨으로서 효율을 증대시킨다. 냉각기(5)를 통과한 과냉된 액냉매는 팽창밸브(17)에서 압력강하가 이루어지고 증발기(6)로 유입된다. 이때 냉수(22)가 증발기 상부에서 유입되어 냉매를 증발시킨 후 토출(23)되게 된다. 증발기(6)에서 증발된 증기냉매는 냉각기(5)의 내부로 들어가 외부관 속에 흐르는 액냉매를 과냉시킨후 흡수기로 유입되어 상부에서 오는 약용액에 흡수되면서 약간의 저압을 형성시켜 계속적인 흐름이 가능하도록 한다. 재생기(1)에서 넘어오는 고온의 약용액은 흡수기(9) 상부의 분사관에 유입된 후 저온의 강용액이 흐르는 용액냉각흡수기(8)의 열교환코일 표면에 분산 낙하되면서 냉각되어 증기냉매의 흡수를 가속시킴과 동시에 흡수율을 높여 효율을 증대시킨다. 또한 용액 냉각흡수기(7)의 열교환코일 표면위로 분산 낙하되는 용액과 열교환을 하여 온도가 상승되고 이는 팬코일부에서 외기와 열교환하게 된다. 이 강용액은 비교적 저온으로 용액펌프(10)에 의해 강용액유로(14)를 통해 정류기(3)로 유입되면서 고온의 증기냉매와 열교환을 하고 또 다시 용액냉각흡수기(8)의 열교환코일 내부측으로 흐르면서 고온의 약용액과 열교환을 하여 온도가 상승된 후 애널라이저(2) 상부로 공급된다. 이와같은 강용액은 전술한 작동들을 순차적으로 반복함으로서 운전을 계속 유지하게 한다.The conventional absorption system configured as described above is converted into a strong solution having a high concentration of ammonia due to the continuous absorption in the absorber 9, which is pumped to the regenerator 1 by the solution pump 10. The steel solution is heated by the burner 11, which is the combustion section of the regenerator 1, to be converted into a chemical solution by evaporation of the ammonia refrigerant, and the expansion valve 13 on the chemical solution passage 12 is placed above the absorber 9 of the low pressure portion. It flows through. On the other hand, the evaporated ammonia refrigerant vapor passes through the analyzer (2) and the rectifier (3) to become ammonia vapor of higher purity and temperature, and enters the condenser (4) through the refrigerant vapor passage (15). It cools by 20 and changes into the liquid refrigerant 16. The ammonia liquid refrigerant flows through the outer tube of the cooler 5 and at this time, mutual heat exchange is performed between the low-temperature steam refrigerants flowing through the inner tube, so that the liquid refrigerant is supercooled and the steam refrigerant is overheated to increase efficiency. The subcooled liquid refrigerant passing through the cooler (5) is a pressure drop in the expansion valve 17 is introduced into the evaporator (6). At this time, the cold water 22 is introduced from the upper part of the evaporator to evaporate the refrigerant and then discharged 23. The vapor refrigerant evaporated from the evaporator (6) enters the inside of the cooler (5) and supercools the liquid refrigerant flowing in the outer tube, and then flows into the absorber and is absorbed by the medicinal solution from the top to form a slight low pressure, thereby continuing the flow. Make it possible. The high temperature chemical solution from the regenerator 1 flows into the injection pipe of the upper part of the absorber 9 and is cooled by being dispersed and dropped on the surface of the heat exchange coil of the solution cooling absorber 8 through which the low temperature strong solution flows. While increasing the efficiency and increase the absorption rate at the same time. In addition, the temperature is raised by heat exchange with a solution that is dispersed and dropped on the surface of the heat exchange coil of the solution cooling absorber 7, and the temperature is increased in the fan coil part. The steel solution flows into the rectifier 3 through the steel solution channel 14 by the solution pump 10 at a relatively low temperature, thereby exchanging heat with the high temperature steam refrigerant and again into the heat exchange coil inside the solution cooling absorber 8. As it flows, it exchanges heat with a hot chemical solution, and the temperature is raised, and then is supplied to the upper part of the analyzer (2). This strong solution keeps running by repeating the above-described operations sequentially.

도 2 는 종래 급탕용 온수장치를 나타낸 것이다. 사용자가 급탕용 온수를 얻고자 할 때 시스템을 운전시켜야 하기 때문에 도 2 의 연소용 버너(11)로 재생기(1)를 가열시키며, 이때 냉수입구라인(3')으로 부터 냉수가 공급되고 재생기(1)에서 발생되는 냉매증기와 열교환을 시켜 급탕용 온수를 얻는다. 이 얻어진 온수는 온수출구(4') 라인으로 유출되어 필요로 하는 장소로 공급되어 진다.Figure 2 shows a conventional hot water heater. When the user needs to operate the system to obtain hot water for hot water supply, the regenerator 1 is heated by the combustion burner 11 of FIG. 2, where cold water is supplied from the cold inlet line 3 'and the regenerator ( Heat-exchanged with refrigerant vapor generated in 1) to obtain hot water for hot water supply. The obtained hot water flows out to the hot water outlet 4 'line and is supplied to the required place.

그러나 종래 시스템은 급탕용 온수를 얻고자 할 때는 항상 시스템을 운전시켜야 하며 또한 그 정상상태가 될 때까지는 원하는 급탕용 온수의 온도까지 얻는 것은 불가능하다. 따라서 그만한 시간이 소요되며 급탕용 온수만을 위해 시스템을 전체 가동시켜야 하거나 또는 보일러식으로 재생기(1)부 만을 별도로 설치를 하여 보일러식으로 그 재생기만을 가동시켜야 하는 문제가 있다. 그리고 급탕용 온수를 사용할 때 초기에 사용자에게 차가운 물이 유출되어 불쾌감을 주게된다.However, the conventional system must always operate the system to obtain hot water for hot water supply, and it is impossible to obtain the desired temperature of hot water for hot water until it reaches a steady state. Therefore, it takes a long time and there is a problem that the entire system must be operated only for hot water for hot water supply, or only the regenerator 1 is installed separately in a boiler type to operate only the regenerator in a boiler type. In addition, when using hot water for hot water, cold water is leaked to the user at an early stage, causing discomfort.

본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로 재생기내부의 급탕용 온수공급장치에 열저장부재를 결합시킴으로서, 온수공급시 부재가 저장한 열을 사용하여 온수를 바로 공급가능하도록 하는데 목적이 있다.The present invention is invented to solve the problems of the prior art as described above by coupling the heat storage member to the hot water supply device for hot water supply inside the regenerator, it is possible to supply hot water directly using the heat stored in the hot water supply The purpose is to help.

이와같이 구성되는 본 발명의 시스템은 시스템이 냉방 또는 난방을 위해 운전할 때 이 열저장합금(106)은 운전중에 재생기에서의 고온의 열을 저장하게 된다. 이 열저장물체는 시스템이 설치되고 일단 가동만 되면 그 이후 부터는 시스템이 가동되었거나 정지되어 있든 상관없이 시스템 운전중 저장된 고온의 열을 급탕용 온수에 열을 가해줄 수 있다. 따라서 시스템이 정지중일때도 급탕용 온수를 필요로 하게 되면 언제든지 온수를 공급할 수 있는 것이다.The system of the present invention thus constructed allows the heat storage alloy 106 to store hot heat in the regenerator during operation when the system is operating for cooling or heating. The heat storage object can heat hot water for hot water stored during system operation regardless of whether the system is started or stopped after the system is installed and started. Therefore, when hot water for hot water supply is required even when the system is stopped, hot water can be supplied at any time.

이상 설명한 바와같이 본 발명의 온수공급장치는 급탕용 온수를 필요시 별도의 시스템 가동없이 바로 온수를 얻을수 있으며, 또한 급탕용 온수만을 위한 재생기를 별도로 설치하지 않아도 됨으로 제품의 효율을 향상시키는 효과가 있다.As described above, the hot water supply device of the present invention can directly obtain hot water without hot water for hot water for hot water supply, and improves the efficiency of the product by not having to separately install a regenerator for hot water for hot water. .
