Description
본 고안은 역류방지수단을 구비한 흡수식 냉온수기에 관한 것으로, 보다 상세하게는, 재생기 펌프의 정지시 고압의 고온재생기와 저압의 흡수기의 압력차로 인하여, 고온재생기에서 용액이 흡수기쪽으로 역류하는 것을 방지하는 역류방지수단을 구비한 흡수식 냉온수기에 관한 것이다.The present invention relates to an absorption chiller having a backflow prevention means, and more particularly, due to the pressure difference between the high pressure high temperature regenerator and the low pressure absorber when the regenerator pump is stopped, it is possible to prevent the solution from flowing back to the absorber in the high temperature regenerator. It relates to an absorption cold and hot water heater having a backflow prevention means.
통상, 이러한 공기조화장치는 사용하는 냉매에 따라 여러 종류로 구분할 수 있으며, 특히 물을 냉매로 사용하는 것으로는 흡수식 냉온수기가 있다. 물을 냉매로 사용하는 흡수식 냉온수기에서는 흡수제로서 리튬브로마이드를 주로 사용하며, 증기나 고온수를 이용하여 물과 리튬브로마이드 용액을 가열하는 바, 본 고안의 이해를 돕기 위해 첨부한 도 1을 참조하여 일반적인 흡수식 냉온수기에 대하여 간략히 설명한다.In general, such an air conditioner may be classified into various types according to a refrigerant to be used, and in particular, water is used as a refrigerant to absorb cold and hot water. In the absorption type cold and hot water machine using water as a refrigerant, lithium bromide is mainly used as an absorbent, and water and lithium bromide solution are heated using steam or high temperature water. Referring to FIG. Brief description of the absorption chiller.
도 1은 일반적인 흡수식 냉온수기의 구성을 설명하기 위한 개략도이다. 여기에 도시된 바와 같이, 흡수식 냉온수기의 대략적인 구성을 보면, 고온 열교환기(11)에서 유입된 희용액을 가열하는 상부의 고온재생기(5)와, 이 고온재생기(5)로부터 유입된 희용액이 수증기로 증발되어 응축되는 응축기(4)가 내장된 저온재생기(3)와, 응축기(4)로부터 유입된 응축수가 증발되는 증발기(2) 및 흡수제에 의해서 증발된 물을 흡수하는 흡수기(1)로 이루어져 있다.1 is a schematic view for explaining the configuration of a general absorption chiller. As shown here, in the general configuration of the absorption chiller, the upper part of the high temperature regenerator 5 for heating the rare solution introduced from the high temperature heat exchanger 11 and the rare solution introduced from the high temperature regenerator 5 are shown. A low temperature regenerator 3 having a condenser 4 which is evaporated and condensed by the water vapor, an evaporator 2 in which the condensed water introduced from the condenser 4 is evaporated, and an absorber 1 which absorbs water evaporated by the absorbent. Consists of
미설명 부호, 12 는 응축냉매 강화관이고, 14 및 15는 냉수 입구 및 출구이고, 16 및 16'은 냉각수 입구(w/i) 및 출구(w/o)이며, 24는 냉매이며, 25는 추기장치이다.Reference numeral 12 denotes a condensation refrigerant reinforcement tube, 14 and 15 are cold water inlet and outlet, 16 and 16 'are cooling water inlet (w / i) and outlet (w / o), 24 is a refrigerant, 25 is It is an additional device.
한편, 상기 고온재생기(5)로 보내진 희용액은 가스(20)를 연료로 하는 버너의 가열에 의해서 중용액 상태로 변환된다. 여기에서 희용액과 중용액 및 농용액(22)은 리튬브로마이드 용액으로서, 그 농도의 정도에 따라 분류한 것이다.On the other hand, the rare solution sent to the high temperature regenerator 5 is converted into a heavy solution state by heating of a burner using gas 20 as a fuel. Here, the rare solution, the heavy solution, and the concentrated solution 22 are lithium bromide solutions, which are classified according to the degree of concentration thereof.
그러한 중용액은 중용액 배관(21)을 통해서 저온 재생기(8)로 보내지며, 이때, 상기 고온 열교환기(11)에서 열교환을 하게 된다. 또한, 배기가스(g)는 고온재생기(5)의 배기덕트(26)를 통해서 외부로 배출된다. 그리고, 고온재생기(5)에서 발생한 증기는 증기 배관(18)을 통하여 증발기(2) 쪽으로 전달된다.Such a heavy solution is sent to the low temperature regenerator 8 through the heavy solution pipe 21, in which the heat exchanger 11 performs heat exchange. In addition, the exhaust gas g is discharged to the outside through the exhaust duct 26 of the high temperature regenerator 5. In addition, the steam generated in the high temperature regenerator 5 is transferred to the evaporator 2 through the steam pipe 18.
그러한 종래의 흡수식 냉온수기에는 용액을 공급시키는 다수의 재생기 펌프(6)와 흡수기 펌프(7) 및 냉매 펌프(8)가 설치되어 있다.Such conventional absorption chiller and water heaters are provided with a plurality of regenerator pumps 6, absorber pumps 7, and refrigerant pumps 8 for supplying a solution.
이 중에서 재생기 펌프(6)는 희용액 배관(23) 상에 배관된 저온 열교환기(10) 및 고온 열교환기(11)를 통해, 흡수기(1)에서 배출된 희용액을 고온재생기(5)로 보내는 역할을 한다. 이러한 역할을 하는 재생기 펌프(6)와 저온 열교환기(10)를 연결하는 배관에는 솔레노이드 타입의 전자제어밸브(9)가 부착되어 있다. 이런 전자제어밸브(9)는 희용액의 유동량을 제어하는데 사용된다. 여기에서, 상기 재생기 펌프(6)와 전자제어밸브(9)의 작동은 상기 고온재생기(5)의 레벨 제어(level control) 수단에 의해서 제어된다.The regenerator pump 6 transfers the rare solution discharged from the absorber 1 to the high temperature regenerator 5 through the low temperature heat exchanger 10 and the high temperature heat exchanger 11 piped on the rare solution pipe 23. It plays a role of sending. The solenoid type electronic control valve 9 is attached to the pipe connecting the regenerator pump 6 and the low temperature heat exchanger 10 which play such a role. This electronic control valve 9 is used to control the flow amount of the rare solution. Here, the operation of the regenerator pump 6 and the solenoid control valve 9 is controlled by the level control means of the high temperature regenerator 5.
이와 같은 종래의 흡수식 냉온수기의 희용액은 재생기 펌프(6)를 출발하여 고온재생기(5)로 유입된다. 그리고, 종래의 흡수식 냉온수기의 특성상, 많은 부하량을 받는 재생기 펌프(6)는 흡수식 냉온수기 운전중에 작동 및 정지를 반복한다.Such a rare solution of the conventional absorption chiller and hot water is introduced into the high temperature regenerator 5 starting from the regenerator pump 6. And, due to the characteristics of the conventional absorption chiller, the regenerator pump 6, which receives a large load, repeatedly starts and stops during the absorption chiller.
이런 과정에서 고온재생기(5) 내부의 희용액이 적정 레벨(level)까지 도달하면, 고온재생기(5) 레벨 제어 수단에 의해서 재생기 펌프(6)는 정지하며, 이와 동시에 전자제어밸브(9)가 닫히게 된다. 이때, 전자제어밸브(9)는 종래의 흡수식 냉온수기의 작동 특성상, 완전하게 닫히지 못하고 20% ∼ 30%의 개방한 상태를 유지하게 된다.In this process, when the rare solvent in the high temperature regenerator 5 reaches a proper level, the regenerator pump 6 is stopped by the high temperature regenerator 5 level control means, and at the same time, the solenoid control valve 9 It is closed. At this time, the solenoid control valve 9 is maintained in an open state of 20% to 30% without being completely closed due to the operating characteristics of the conventional absorption type cold and hot water heater.
그러한, 종래 기술에 따른 흡수식 냉온수기는 운전 특성상, 전자제어밸브를 완벽하게 개폐시키지 못하므로써, 고온재생기의 압력 730㎜Hg와 흡수기의 압력 6㎜Hg의 상대적인 압력차에 의해, 희용액을 상기 고온재생기에서 흡수기쪽으로 역류를 발생시키는 단점이 있다.Such a cold and hot water absorber according to the prior art does not open and close the solenoid control valve completely due to its operation characteristics, so that the rare liquid is converted into the hot water regenerator by a relative pressure difference between the pressure of the hot regenerator 730 mmHg and the absorber pressure 6 mmHg. There is a disadvantage in that backflow occurs at the absorber.
이와 같은 문제점을 해결하기 위해 안출한 본 고안의 목적은 역류방지수단인 균압관을 설치하므로써, 고온재생기에서 흡수기로 희용액이 역류되는 것을 방지할 수 있는 역류방지수단을 구비한 흡수식 냉온수기를 제공하는데 있다.The purpose of the present invention devised to solve such a problem is to provide an absorption type cold and hot water heater equipped with a backflow prevention means that can prevent the backflow of the rare solution from the high temperature regenerator to the absorber by installing a pressure equalizing tube as a backflow prevention means. have.

상술한 본 고안의 목적은 용액 배관을 통하여 재생기 펌프로 가압송시킨 흡수제 용액을 가열하는 고온 재생기와, 상기 고온 재생기로부터 유입된 용액이 수증기로 증발되어 응축되는 응축기를 설치한 저온 재생기와, 상기 응축기로부터 유입된 응축수가 증발되는 증발기 및, 증발된 물을 흡수제로 흡수시키는 흡수기를 구비한 버너용 공기냉각기를 구비한 흡수식냉동기에 있어서, 상기 고온재생기와 상기 용액 배관을 연통하게 배관한 균압관을 포함하며, 상기 균압관은 재생기 펌프의 정지시, 상기 고온재생기의 내부압력과 흡수기의 내부압력을 균일하게 하는 것을 특징으로 하는 역류방지수단을 구비한 흡수식 냉온수기에 의해 달성된다.An object of the present invention described above is a high temperature regenerator for heating the absorbent solution pressurized by a regenerator pump through a solution pipe, a low temperature regenerator having a condenser in which the solution introduced from the high temperature regenerator is evaporated and condensed with water vapor, and the condenser. An absorption chiller having an evaporator for evaporating condensed water from and a burner air cooler having an absorber for absorbing the evaporated water as an absorbent, comprising: a pressure equalizing pipe configured to communicate the hot regenerator with the solution pipe; The equalizing pipe is achieved by an absorption type cold and hot water machine equipped with a backflow preventing means, in which the internal pressure of the high temperature regenerator and the internal pressure of the absorber are equalized when the regenerator pump is stopped.
또한, 본 고안에 따르면, 상기 균압관은 고온재생기의 증기실과 상기 용액 배관의 입구에 연통하게 배관되어 있는 것이 바람직하다.In addition, according to the present invention, the equalizing pipe is preferably piped in communication with the steam chamber of the high temperature regenerator and the inlet of the solution pipe.
이하, 첨부한 도 2 내지 도 3을 참조하여 본 고안의 바람직한 실시예에 따른 역류방지수단을 구비한 흡수식 냉온수기에 대하여 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying Figures 2 to 3 will be described in detail with the absorption type cold and hot water machine having a backflow prevention means according to a preferred embodiment of the present invention.
이 실시예에서 설명하는 본 고안의 역류방지수단을 구비한 흡수식 냉온수기는 고온재생기의 증기실과 희용액 배관을 서로 관통하게 연결하는 균압관을 제외하고는 종래 기술과 동일하다. 그러므로, 도 1 내지 도 3에서 동일하거나 대응하는 구성요소에 대해서는 동일하거나 유사한 도면부호가 부여될 것이며, 이것들에 대한 설명은 여기에서 생략될 것이다.Absorption chiller and water heater equipped with a backflow prevention means of the present invention described in this embodiment is the same as the prior art except for the equalization pipe for connecting the vapor chamber and the rare water pipe of the high temperature regenerator through each other. Therefore, the same or similar reference numerals will be given to the same or corresponding components in FIGS. 1 to 3, and the description thereof will be omitted here.
도면에서, 도 2는 본 고안의 역류방지수단을 구비한 흡수식 냉온수기의 구성을 설명하기 위한 개략도이며, 도 3은 도 2에 도시된 역류방지수단을 구비한 흡수식 냉온수기의 결합관계를 설명하기 위해서 중요부위를 확대한 도면이다.In the drawings, Figure 2 is a schematic diagram for explaining the configuration of the absorption type cold and hot water heater with a backflow prevention means of the present invention, Figure 3 is important for explaining the coupling relationship of the absorption chiller and water with a backflow prevention means shown in Figure 2 It is an enlarged view of a part.
도 2에 보이듯이, 본 고안의 역류방지수단을 구비한 흡수식 냉온수기는 역류방지수단으로 사용되는 균압관(100)을 갖는다. 이런 균압관(100)은 일반적인 파이프 형상으로 형성되어 있다. 또한, 균압관(100)은 증발기(2)와 흡수기(1)를 담고 있는 셀(shell)의 내부압력에 의해서, 희용액 배관(230)의 희용액에서 발생하는 압력차이를 균일하게 하는 역할을 한다.As shown in FIG. 2, the absorption type cold and hot water machine equipped with the backflow preventing means of the present invention has a pressure equalizing tube 100 used as the backflow preventing means. This pressure equalizing pipe 100 is formed in a general pipe shape. In addition, the pressure equalizing tube 100 serves to equalize the pressure difference generated in the rare solution of the rare solution pipe 230 by the internal pressure of the shell containing the evaporator 2 and the absorber 1. do.
이렇게 희용액 배관(230)의 압력차이를 균일하게 하기 위해서는, 재생기 펌프(6)의 정지시, 흡수기(1)의 내부압력과 동일한 크기인 증기 배관(18)의 내부압력을 희용액 배관(230)의 내부압력과 동일하게 해주면 된다.In order to make the pressure difference of the rare solution pipe 230 uniform, the internal pressure of the steam pipe 18 having the same size as the internal pressure of the absorber 1 at the time of stopping the regenerator pump 6 is increased. The internal pressure of) should be the same.
이를 실현하기 위해서, 도 2 및 도 3에 보이듯이, 상기 균압관(100)의 한쪽 단부는 희용액의 가열시 발생하는 증기를 채울 수 있는 고온재생기(50)의 증기실(51)에 연통하게 배관되어 있다.In order to realize this, as shown in FIGS. 2 and 3, one end of the pressure equalizing tube 100 is in communication with the steam chamber 51 of the high temperature regenerator 50 capable of filling steam generated when the rare solution is heated. Piping
또한, 또한, 상기 균압관(100)의 다른쪽 단부는 희용액 배관(230)의 입구에 연통하게 배관되어 있다.In addition, the other end of the pressure equalizing pipe 100 is piped in communication with the inlet of the rare solution pipe 230.
이렇게 배관될 경우, 증기 배관(18)의 내부압력이 상기 균압관(100)을 통하여, 희용액 배관(230)의 내부압력을 균일화시킨다. 이때, 증기 배관(18)의 내부압력은 흡수기(1)의 내부압력과 동일하다. 따라서, 흡수기(1)의 내부압력은 희용액 배관(230)의 내부압력과 동일하게 된다. 그리고, 상기 균압관(100)은 재생기 펌프(6)의 정지시에도 고온재생기(50)로 유입된 희용액이 흡수기(1)로 역류하는 것을 방지한다.In this case, the internal pressure of the steam pipe 18 equalizes the internal pressure of the rare solution pipe 230 through the equalization pipe 100. At this time, the internal pressure of the steam pipe 18 is equal to the internal pressure of the absorber 1. Therefore, the internal pressure of the absorber 1 is equal to the internal pressure of the rare solution pipe 230. In addition, the pressure equalizing pipe 100 prevents the rare solution introduced into the high temperature regenerator 50 from flowing back into the absorber 1 even when the regenerator pump 6 is stopped.
앞서 상세히 설명한 바와 같이 본 고안의 역류방지수단을 구비한 흡수식 냉온수기는 단순하게 균압관을 고온재생기와 희용액 배관을 연통하게 설치하므로써, 용액의 역류를 방지할 수 있는 장점이 있다.As described in detail above, the absorption type cold and hot water machine equipped with the backflow prevention means of the present invention has an advantage of simply preventing the backflow of the solution by installing the equalization pipe in communication with the high temperature regenerator and the rare solution pipe.
또한, 본 고안의 역류방지수단을 구비한 흡수식 냉온수기는 복잡한 구성을 갖는 별도의 역류방지 장치를 필요로 하지 않기 때문에, 간단한 구성으로 기대 이상의 역류방지 효과가 있다.In addition, since the absorption type cold and hot water machine provided with the backflow prevention means of the present invention does not require a separate backflow prevention device having a complicated configuration, it has a simple configuration has more than expected backflow prevention effect.
이상에서 살펴본 본 고안의 역류방지수단을 구비한 흡수식 냉온수기에 대한 기술사상을 첨부도면과 함께 서술하였지만 이는 본 고안의 가장 양호한 실시예를 예시적으로 설명한 것이지 본 고안을 한정하는 것은 아니다. 또한, 이 기술분야의 통상의 지식을 가진 자이면 누구나 본 고안의 기술사상의 범주를 이탈하지 않는 범위내에서 다양한 변형 및 모방이 가능함은 명백한 사실이다.Although the technical concept of the absorption type cold and hot water machine having the countercurrent prevention means of the present invention described above was described with the accompanying drawings, this is illustrative of the best embodiment of the present invention and is not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
