Description
본 발명은 흡수식 냉,온수기에 관한 것으로서, 더욱 상세하게는 불응축 가스상에 포함된 냉매 및 오일의 대기 방출을 방지할 수 있는 흡수식 냉,온수기의 정화장치에 관한 것이다.The present invention relates to an absorption chiller and water heater, and more particularly, to a purifier of an absorption chiller and water heater capable of preventing the release of refrigerant and oil contained in a non-condensable gas phase.
일반적으로 흡수식 냉,온수기는 리듐브로마이드인 흡수액과 물로 이루어져있는 냉매의 냉방 순환싸이클 및 난방 싸이클이 형성되어 있는 장치로써, 증발기, 재생기, 흡수기 및 응축기로 구성되어 있다.Generally, the absorption chiller and water heater are devices in which cooling circulation cycles and heating cycles of a refrigerant consisting of absorbent liquid and water, which are lithium bromide, are formed, and are composed of an evaporator, a regenerator, an absorber, and a condenser.
이때 냉매의 난방 순환싸이클은 냉매 증기가 증발기를 통과하면서 증발기내에 설치된 튜브를 유동하는 유동액을 가열 하면서 냉각되어 액체 상태의 냉매로 되고 흡수기에서 흡수액이 액체 상태의 냉매를 흡수하여, 묽은 흡수용액이 형성되며 묽은 용액이 재생기에서 냉매증기와 흡수액으로 분리되어 각각 증발기와 흡수리고 유동되는 순환경로에 의해서 이루어진다.At this time, the heating circulation cycle of the refrigerant is cooled while heating the fluid flowing through the tube installed in the evaporator while the refrigerant vapor passes through the evaporator to become a liquid refrigerant, and the absorber absorbs the liquid refrigerant in the absorber. The dilute solution is separated into refrigerant vapor and absorbent liquid in the regenerator, respectively, by a circulation path that is absorbed and flows through the evaporator.
이와는 반대로 냉매의 냉방 순환싸이클은 재생기에서 발생된 냉매 증기는 응축기로 유동하여 응축된 후 증발기로 유동하여 증발기내에 설치된 튜브를 유동하는 유동액을 냉각시키면서 증발되며 증발된 냉매는 흡수기에서 흡수액에 의해 흡수되어 묽은 흡수용액을 형성시키고, 묽은 흡수용액은 재생기에서 냉매 증기와 흡수액으로 분리되어 각각 응축기와 흡수기로 유동되는 유동경로에 의해서 이루어진다.On the contrary, the cooling cycle of refrigerant cools the refrigerant vapor generated in the regenerator to flow to the condenser, condenses and then flows to the evaporator to cool the fluid flowing through the tube installed in the evaporator, and the evaporated refrigerant is absorbed by the absorber in the absorber. The thin absorbent solution is separated into refrigerant vapor and absorbent liquid in the regenerator and is formed by a flow path flowing to the condenser and the absorber, respectively.
한편, 냉매의 냉방 순환싸이클이 형성될 때, 응축기에서 응축되지 않은 불응축 가스가 형성되며, 이러한 불응축 가스는 냉,온수기의 냉방 운전시 냉매의 응축을 저해하며 동시에 토출압력과 온도가 상승되어 운전부하가 상승하는등 냉,온수기의 냉방 운전에 악영향을 미치므로 이러한 불응축 가스를 냉,온수기 외부로 배출시키는 것이 요구되었다.On the other hand, when the cooling cycle of the refrigerant is formed, non-condensed gas is not condensed in the condenser is formed, this non-condensing gas inhibits the condensation of the refrigerant during the cooling operation of the cold, hot water heater and at the same time the discharge pressure and temperature is increased It is required to discharge such non-condensable gas to the outside of the chiller and water heater because it adversely affects the cooling operation of the chiller and water heater, such as an increase in the operating load.
이를 위하여 종래에는 제1도에 도시된 정화 유니트가 제안되어 있다.For this purpose, the purification unit shown in FIG. 1 is conventionally proposed.
이는, 흡수액 순환 시스템의 응축기(미도시)와 관로(P1)를 통해 연결된 저장조(1)의 내부에는 유입장치(2)를 통해 오일(3)이 유입되게 되며, 이 저장조(1)내부에는 유입된 오일(3)을 냉각 시키기 위한 오일 냉각기(4)가 위치된다.This, the oil (3) is introduced into the reservoir (1) connected through the condenser (not shown) and the pipeline (P1) of the absorption liquid circulation system through the inlet device (2), the inlet inside the reservoir (1) An oil cooler 4 is located for cooling the finished oil 3.
또한 저장조(1)의 상부에는 분리된 불응축 가스를 외부로 방출하기 위한 배출장치로써, 첵크 밸브(5)가 마련되어 있다.Moreover, the check valve 5 is provided in the upper part of the storage tank 1 as a discharge apparatus for discharge | released the separated non-condensable gas to the outside.
그러나 이와같은 종래의 정화 유니트에 있어서는, 배출장치 즉, 첵크 밸브(5)를 통해 방출되는 불응축 가스상에 미세하나마 냉매가스 및 오일이 섞여 방출되는 문제점이 있다.However, in such a conventional purification unit, there is a problem in that fine refrigerant gas and oil are mixed and discharged on the non-condensable gas discharged through the discharge device, that is, the check valve 5.
이때 특히 냉매가스인 R11, R123은 대기중의 오존층 파괴지수가 매우 높아 환경문제를 야기시키게 되며, 또한 미량이나마 방출되는 오일에 의해서는 유니트 내의 오일량의 손실이 발생되어 재충진 시켜주어야만 했다.At this time, the refrigerant gases R11 and R123 have very high ozone depletion potential in the atmosphere, causing environmental problems. Also, the amount of oil released in the unit has to be refilled due to the loss of oil in the unit.
본 발명은 이와같은 종래의 제반 문제점을 해결하기 위하여 창출된 것으로서, 방출되는 불응축 가스상에 포함된 미량의 냉매가스 및 오일의 방출을 방지할 수 있는 흡수식 냉,온수기의 정화장치를 제공함에 그 목적이 있다.The present invention has been made to solve such problems in the related art, and provides an apparatus for purifying absorption type cold and water heaters capable of preventing the release of trace amounts of refrigerant gas and oil contained in the discharged non-condensable gas phase.

제2도는 본 발명에 따른 흡수식 냉,온수기의 정화장치의 구성도이다.2 is a block diagram of a purification apparatus for absorption cold and hot water heaters according to the present invention.
이에 도시된 바와 같이 본 발명에 따른 흡수식 냉,온수기의 정화장치는, 크게 도시되지는 않았지만, 증발기와 흡수기 그리고 재생기와 응축기를 갖는 흡수액 순환시스템과, 이 흡수액 순환 시스템의 응축기로 부터 유입된 불응축 가스 및 냉매가스로 부터 불응축 가스와 냉매를 분리시키는 정화 유니트(Purge unit;10)와, 이 정화유니트(10)에 분리된 불응축 가스에 포함된 미량(微量)의 냉매와 오일이 대기(大氣)중으로 방출되는 것을 방지하기 위한 냉매 및 오일 회수수단(20)으로 대별된다.As shown therein, the apparatus for purifying absorbent cold and hot water according to the present invention, although not largely shown, is an absorbent circulation system having an evaporator, an absorber, a regenerator and a condenser, and a non-condensation introduced from the condenser of the absorbent circulation system. A purge unit (10) for separating the non-condensable gas and the refrigerant from the gas and the refrigerant gas, and a small amount of refrigerant and oil contained in the non-condensed gas separated in the purification unit (10) It is roughly divided into refrigerant and oil recovery means 20 for preventing it from being released into the tank.
전술한 정화 유니트(10)의 구조를 보면, 흡수액 순환 시스템의 응축기(미도시)와 관로(P1)를 통해 연결된 저장조(11)의 내부에는 유입장치(12)를 통해 오일(13)이 유입되게 되며, 이 저장조(11) 내부에는 유입된 오일(13)을 냉각 시키기 위한 오일 냉각기(14)가 위치된다.Looking at the structure of the above-described purification unit 10, the oil 13 is introduced through the inlet device 12 into the reservoir 11 connected through the condenser (not shown) and the pipeline (P1) of the absorbent liquid circulation system. In this reservoir 11, an oil cooler 14 for cooling the introduced oil 13 is positioned.
한편, 본 발명의 실질적인 특징적 구성을 갖는 회수수단(20)의 구조를 보면, 전술한 정화 유니트(10)의 내부와 즉, 저장조(11)의 내부와 관로(P2)를 통해 연결되는 필터(21)를 구비하는 바, 이 필터(21)의 내부에는 불응축 가스중에 포함된 오일과 냉매를 분리하기 위한 오일(13)이 유입된다.On the other hand, when looking at the structure of the recovery means 20 having a substantially characteristic configuration of the present invention, the filter 21 is connected to the inside of the above-described purification unit 10, that is, the inside of the reservoir 11 through the conduit P2. In the filter 21, the oil 13 for separating the refrigerant contained in the non-condensable gas and the refrigerant flows into the filter 21.
또한 필터(21)의 외주면에는 필터(21)내부의 오일(13)을 냉각시킴으로써, 불응축 가스중에 포함된 냉매와 오일의 분리를 촉진시키기 위한 냉각코일(22)이 다수권회 설치된다.In addition, a plurality of winding coils 22 are provided on the outer circumferential surface of the filter 21 to cool the oil 13 inside the filter 21 to promote separation of refrigerant and oil contained in the non-condensable gas.
이때 필터(21)의 일측면상에는 냉매가스와 오일이 포함되어 있지 않은 즉, 정화된 불응축 가스를 외부로 즉, 대기중으로 방출하기 위한 배출장치의 하나로써, 첵크밸브(23)가 마련된다.At this time, the check valve 23 is provided on one side of the filter 21 as one of the discharge devices for releasing the purified non-condensable gas to the outside, that is, the atmosphere, which does not contain refrigerant gas and oil.
한편, 전술한 필터(21)상에 냉매가스가 분리되고, 또한 불응축 가스중의 오일이 녹아 함유된 상태에서 어느정도 일정량의 오일(13)이 저장되게 되면, 이를 회수하여 흡수액 순환 시스템(미도시)상으로 회수하기 위한 에덕트(Eductor;24)가 마련된다.On the other hand, if the refrigerant gas is separated on the filter 21 and the oil 13 is stored to some extent in a state in which the oil in the non-condensing gas is dissolved, it is recovered and absorbed liquid circulation system (not shown) An duct 24 is provided for recovery to the phase.
이와같이 구성된 본 발명에 따른 작동상태를 설명하면 다음과 같다.Referring to the operating state according to the invention configured as described above are as follows.
먼저, 정화유니트(10)상에서 흡수액 순환 시스템의 응축기로 부터 유입된 불응축 가스 및 냉매가스는, 저장조(11)내에 유입된 오일(13)과 오일 냉각기(14)를 통해 분리된다.First, the non-condensing gas and the refrigerant gas introduced from the condenser of the absorbent liquid circulation system on the purification unit 10 are separated through the oil 13 and the oil cooler 14 introduced into the storage tank 11.
이때 분리된 불응축 가스는, 관로(P2)를 통해 연결된 회수수단(20)의 구성요소인 필터(21)내부로 유입되게 되고, 동시에 이 필터(21)의 내부에 유입된 오일(13)과 그 외주면에 권회된 냉각코일(22)에 의해 불응축 가스중에 포함된 오일과 냉매가스가 오일(13)상에 융해되게 된다.At this time, the separated non-condensable gas is introduced into the filter 21 which is a component of the recovery means 20 connected through the pipe line P2, and at the same time, the oil 13 and the oil 13 introduced into the filter 21 Oil and refrigerant gas contained in the non-condensed gas are melted on the oil 13 by the cooling coil 22 wound on the outer circumferential surface thereof.
이때 냉각코일(22)에 의해서는 냉매가스의 분리 즉, 융해가 더욱 촉진되게 된다.At this time, the cooling coil 22 further promotes separation of the refrigerant gas, that is, melting.
이와같이 미량의 냉매가스와 오일성분이 제거된 불응축 가스는 필터(21)의 일측면에 마련된 첵크밸브(23)를 통해 대기중으로 방출되게 되고, 동시에 필터(21)내의 오일은 에덕트(24)를 통해 흡수액 순환 시스템으로 회수되게 한다.As such, the non-condensable gas from which the trace amount of the refrigerant gas and the oil component are removed is discharged into the atmosphere through the check valve 23 provided on one side of the filter 21, and at the same time, the oil in the filter 21 is discharged into the duct 24. Through the absorbent circulation system.
상술한 바와 같이 본 발명에 따른 흡수식 냉,온수기의 정화장치에 의하면, 대기중으로 방출되는 불응축 가스상에 포함된 미량의 냉매가스 및 오일을 제거할 수 있게됨으로써, 오존층을 파괴하는 환경오염 문제를 제거할 수 있으며, 회수된 오일을 통해 오일을 재충전을 할 필요가 없는등의 이점이 있다.As described above, according to the purification apparatus of the absorption type cold and hot water heater according to the present invention, it is possible to remove the trace amount of refrigerant gas and oil contained in the non-condensable gas discharged into the air, thereby eliminating the problem of environmental pollution that destroys the ozone layer. It may be possible, and there is no need to refill the oil through the recovered oil.
