Description

냉방기용 냉각파이프Cooling pipe for cooler

본 발명은 냉방기용 냉각파이프에 관한 것으로서, 특히 빙축식 냉방기(또는 냉방기)의 냉각파이프를 3중관으로 구비하여 냉방효율을 높일 수 있게 한 냉방기용 냉각파이프에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling pipe for a cooling machine, and more particularly, to a cooling pipe for a cooling device which is provided with a cooling pipe of a ice-maker cooling device (or a cooling device)

일반적으로 빙축식 냉방기는 열교환기에서 열교환을 이루어 냉방이 이루어지도록 냉가수를 일정시간 동안 빙축시키도록 하고, 상기 빙축된 상태에서 필요에 따라 작은 에너지를 이용하여 냉방공기를 외부로 공급시킬 냉방기능을 수행할 수 있게 한 것이다.In general, the ice-making type cooling machine is configured to perform a cooling function to cause the cold water to be ice-cooled for a predetermined period of time so that the heat is exchanged in the heat exchanger, and the cooling air is supplied to the outside by using a small energy, It is possible to carry out.

이러한 빙축식 냉방기에는 냉각수를 빙점 이하에서 결빙시킬 수 있게 하는 냉매가스 순환파이프인 냉매파이프가 구성되고, 냉매파이프의 냉각온도에 의해 저온 상태로 열교환기에 순환되어 열교환이 이루어지는 부동액의 냉각수파이프가 일반적으로 구성된다.In this type of ice-cooled cooling machine, a cooling water pipe constituting a refrigerant gas circulating pipe that allows freezing of cooling water below the freezing point is constituted, and a cooling water pipe of an antifreeze which is circulated through a heat exchanger in a low- .

따라서, 수냉식 냉방기의 경우 열교환기로 유입되어 순환되는 냉각수의 온도가 5℃정도가 유지되고, 열교환을 거쳐 회수되는 냉각수는 10℃정도가 유지되며, 냉각수의 열교환시 증폭되는 냉각공기는 13℃정도의 온도를 유지하여 냉방이 이루어지게 한 것이다.Accordingly, in the case of the water-cooled type air conditioner, the temperature of the cooling water flowing into the heat exchanger and circulated is maintained at about 5 DEG C, the cooling water recovered through heat exchange is maintained at about 10 DEG C, So that the cooling is maintained by maintaining the temperature.

이와 같이 된 종래의 빙축식 냉방기의 냉각파이프(CP)를 설명하면 도 4에서 보는 바와 같이 내부에 냉매파이프(FP)와 외부에 부동액의 냉각수가 유입된 냉각수파이프(CWP)가 구비되어 냉매파이프(FP)가 냉각수파이프(CWP)에 직접 접촉되는 방식의 2중관으로 구성되었다.As shown in FIG. 4, the cooling pipe (CP) of the conventional ice-maker type cooling machine has a coolant pipe (FP) inside and a coolant pipe (CWP) FP) was in direct contact with the cooling water pipe (CWP).

상기 냉각파이프(CP)는 일측의 냉매파이프(FP)를 압축기(C)에 연결시키고, 타측은 응축기(E)에 연결시키며, 냉각수파이프(CWP)의 일측과 타측은 열교환기(HE)의 유입 및 배출부측에 연결 구성된다.The cooling pipe CP connects one side of the refrigerant pipe FP to the compressor C and connects the other side to the condenser E. One side and the other side of the cooling water pipe CWP are connected to the inflow And the discharge side.

이러한 냉각파이프(CP)는 압축기(C)에서 압축된 고압 저온의 냉매가스가 냉매파이프(FP)를 거쳐 순환된후 응축기(E)를 거쳐 저압 고온의 냉매가스가 압축기(C)로 공급되면서 상기의 연속작용에 의해 냉각수파이프(CWP)의 냉각수를 저온 상태로 유지시키도록 하고, 동시에 빙축식 냉방기에 있어서는 소정의 케이스(CS) 내부에 구성된 2중관 외부의 냉각수(W)를 결빙시키도록 한다.The cooling pipe CP circulates the high-pressure and low-temperature refrigerant gas compressed by the compressor C through the refrigerant pipe FP, and then the low-pressure and high-temperature refrigerant gas is supplied to the compressor C through the condenser E, The cooling water of the cooling water pipe (CWP) is maintained at a low temperature state by the continuous action of the cooling water pipe (CWP), and at the same time, the cooling water (W)

이렇게 냉각수(W)를 결빙시킨 상태에서 냉방기능을 시행하기 위해 냉각수파이프(CWP)내의 부동액 냉각수를 열교환기(HE)로 순환시키면 열교환기에서 열교환을 이루면서 외부로 냉각공기를 배출시키도록 하고, 동시에 부동액 냉각수는 열교환에 의해 상온으로 온도가 변화되어 회수되며, 회수된 부동액 냉각수는 냉매가스와 외부의 결빙 상태의 냉각수(W)에 의해 저온으로 냉각된 상태에서 열교환기(HE)로 연속 순환작용을 하면서 냉방기능이 수행되도록 한다.When the antifreeze cooling water in the cooling water pipe (CWP) is circulated to the heat exchanger (HE) to perform the cooling function in the state where the cooling water (W) is freeze, the cooling air is discharged to the outside while performing heat exchange in the heat exchanger The antifreeze cooling water is recovered by changing the temperature to room temperature by heat exchange. The recovered antifreeze cooling water is continuously circulated to the heat exchanger (HE) in a state where the refrigerant gas and the cooling water (W) So that the cooling function is performed.

그러나, 상기 냉각파이프(CP)의 2중관은 냉각수파이프(CWP)내의 냉가수와 냉매파이프(CP)가 직접 접촉된 상태에서 압축된 냉매가스가 냉각파이프(CP)로 유입되어 순환될 때 원형 및 그 밖의 소정형태로 권취된 2중관의 전체 부피중 돌기 단계의 영역(A1)과 중간단계의 영역(A2)과 후기 단계의 영역(A3)에 각기 냉각조건의 변화가 심하게 발생되어 냉각수파이프(CWP)내의 냉각수 냉각효율이 좋지 못하였다.However, the double pipe of the cooling pipe (CP) can be circulated and circulated when the compressed refrigerant gas flows into the cooling pipe (CP) while the cold water in the cooling water pipe (CWP) is in direct contact with the refrigerant pipe A change in the cooling condition is severely generated in the protruding step area A1, the intermediate step area A2 and the later step area A3 in the entire volume of the double pipe wound in the predetermined form, ) Was not good.

즉, 냉각수(W)가 결빙된 상태에서 냉방기능을 수행할 때 냉각수파이프(CWP)의 부동액 냉각수가 열교환을 거쳐 상온상태로 회수된 부동액 냉각수에 의해 빙결된 냉각수(W)가 해빙되어 물 상태로 변화된다.That is, when the cooling function is performed while the cooling water W is frozen, the cooling water W freezing by the antifreezing cooling water recovered at the room temperature through the heat exchange of the antifreeze cooling water of the cooling water pipe (CWP) Change.

따라서, 냉각파이프(CP)의 초기단계 영역(A1)으로 공급되는 냉매가스가 -20℃의 온도를 유지한채 순환되어 부동액 냉각수를 냉각시키도록 하였으나 중간 단계의 영역(A2)에서는 외부의 냉각수(W)와 열교환이 이루어지는 부동액 냉각수와 냉매파이프(FP)가 직접 접촉 구비되어 있어 초기온도인 -20℃보다 일정온도가 상승되므로 초기단계의 영역(A1)보다 냉각효율이 저하되고, 후기단계의 영역(A3)에서는 상기 중간단계의 영역보다 냉매가스의 온도가 더욱 상승하므로 냉각효율의 저하에 따른 냉방기 및 빙축식 냉방기의 냉방기능을 약화시키는 문제점이 있었다.Accordingly, the refrigerant gas supplied to the initial stage region A1 of the cooling pipe CP is circulated while maintaining the temperature of -20 DEG C to cool the antifreeze cooling water. However, in the intermediate region A2, the cooling water W And the refrigerant pipe FP is directly in contact with the refrigerant pipe FP, the cooling efficiency is lower than the initial temperature A1 and the temperature of the latter stage A3), the temperature of the refrigerant gas is higher than that of the intermediate region, so that there is a problem that the cooling function of the radiator and the ice-maker cooling unit is weakened due to the decrease in the cooling efficiency.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 발명한 것으로서, 빙축식냉방기(또는 냉방기) 냉매파이프와 냉각수파이프 사이에 별도의 파이프를 구비하여 냉각파이프를 3중관으로 구성함에 따라 해빙된 냉각수에 접촉된 냉각수파이프의 부동액 냉각수와 냉매파이프가 직접 접촉되는 것을 방지하여 부동액냉각수의 냉각효율을 높일 수 있게 한 것을 목적으로 한다.SUMMARY OF THE INVENTION The present invention has been accomplished in order to solve the above-mentioned problems, and it is an object of the present invention to provide a refrigerator having a separate pipe between a refrigerant pipe and a cooling water pipe, It is an object of the present invention to prevent direct contact between the refrigerant pipe and the antifreeze liquid of the contacted cooling water pipe, thereby increasing the cooling efficiency of the antifreeze liquid cooling water.

도2는 본 발명의 냉각파이프(CP)가 적용된 빙축식냉방기(AC)에 구성된 각 구성부품의 블록 구성도로서, 빙축케이스(CS) 내부에 냉각파이프(CP)가 구성되고, 냉각파이프(P)에 구성된 냉각수파이프(CWP)는 열교환기(HE)와 연결되며, 냉각수파이프(CWP)내에 구성된 냉매파이프(CP)는 압축기(C)와 응축기(E)에 상호 연결 구성되어 있다.FIG. 2 is a block diagram of components of the ice-maker cooler (AC) to which the cooling pipe (CP) of the present invention is applied. The cooling pipe (CP) Is connected to the heat exchanger HE and the refrigerant pipe CP constructed in the cooling water pipe CWP is connected to the compressor C and the condenser E. [

도 3은 본 발명의 냉각파이프(CP)의 일부단면 구성도로서, 빙축케이스(CS)내부에 구비된 냉각파이프(CP)의 내부에 냉매파이프(FP)와 냉매파이프(FP)의 외부에 냉각수파이프(CWP)가 구비되고, 냉매파이프(FP)와 냉각수파이프(CWP) 사이에는 파이프(P)를 구비하여 3중관으로 냉각파이프(CP)가 이루어지도록 한다.3 is a partial cross-sectional view of a cooling pipe CP according to the present invention in which a cooling pipe CP provided inside the ice-casing case CS is provided with a coolant pipe FP and a coolant pipe FP, And a pipe P is provided between the refrigerant pipe FP and the cooling water pipe CWP so that a cooling pipe CP is formed by a triple pipe.

상기한 냉각파이프(CP)는 냉매파이프(FP)와 냉각수파이프(CWP) 사이에 구비된 파이프(P)에 의하여 냉각수파이프(CWP)내에 수용된 부동액냉각수와 냉매파이프(FP)가 직접 접촉되는 것을 방지한다.The cooling pipe CP prevents the refrigerant pipe FP from being in direct contact with the antifreeze cooling water accommodated in the cooling water pipe CWP by the pipe P provided between the refrigerant pipe FP and the cooling water pipe CWP. do.

즉, 냉매파이프(FP)의 외부에 구비된 파이프(P)의 양단부를 밀폐시켜 소정간격의 공간부(S)를 유지하고, 이 공간부(S)에는 진공상태를 유지시키므로서 부동액냉각수와 냉매파이프(FP)의 접촉을 차단시키도록 한 것이다.That is, both ends of the pipe P provided on the outside of the refrigerant pipe FP are sealed to keep the space S at a predetermined interval, and the vacuum state is maintained in the space S, Thereby blocking the contact of the pipe FP.

이와 같이 된 본 발명의 작용을 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.

빙축식냉방기(AC)를 작동에 의해 압축기(C)에서 저온 고압으로 압축된 냉매가스가 빙축케이스(CS)내에 구비된 냉각파이프(CP)내로 공급 순환되어 응축기(E)를 거친 다음 압축기(C)로 유입되게 하고, 이 순환과정은 연속적으로 이루어지도록 한다.The refrigerant gas compressed to the low temperature and high pressure in the compressor C by the operation of the ice-maker type cooler AC is supplied to the cooling pipe CP provided in the ice-casing case CS, passes through the condenser E, ), And this circulation process is performed continuously.

이때 냉매가스는 -20℃정도로 유지한채 순환되므로 외부의 파이프(P)와 냉각수파이프(CWP)내의 부동액냉각수를 냉각시키게 됨과 동시에 빙축케이스(CS)내의 냉각수(W)가 결빙되도록 한다.At this time, since the refrigerant gas is circulated while being kept at about -20 ° C, the antifreeze cooling water in the pipe P and the cooling water pipe CWP is cooled and the cooling water W in the ice-casing case CS is frozen.

이상태에서 냉방기능을 수행하게 되면 3중관으로 이루어진 냉각파이프(CP)에 구성된 냉각수파이프(CWP)에 수용되어진 부동액냉각수가 빙축냉각수(W)와 냉매가스에 의해 5℃정도의 저온으로 냉각된 상태로 열교환기(HE)로 순환되고, 열교환기(HE)에서는 열교환을 이루면서 13℃정도의 냉방송풍이 이루어지게 하며, 동시에 열교환기(HE)를 거쳐 냉각파이프(CP)로 회수되는 부동액냉각수는 10℃의 온도로 상승하여 회수된다.When the cooling function is performed in the ideal state, the antifreeze cooling water accommodated in the cooling water pipe (CWP) formed in the cooling pipe (CP) composed of the triple pipe is cooled to a low temperature of about 5 캜 by the cooling water And the cooling water is circulated through the heat exchanger HE while the heat exchanger HE exchanges heat with cooling air of about 13 DEG C. At the same time, the antifreeze cooling water recovered through the heat exchanger HE through the cooling pipe CP is circulated at 10 DEG C And is recovered.

이때 상온으로 높아진 부동액 냉각수에 의해 빙축케이스(CS)내에 수용된 결빙 냉각수(W)가 서서히 해빙되어 물로 변화하게 되면 냉각수(W)의 온도는 서서히 상온으로 변화된다.At this time, when the ice-freezing water W contained in the ice-shaft case CS is gradually thawed and changed into water by the antifreeze cooling water that has been raised to the normal temperature, the temperature of the cooling water W gradually changes to room temperature.

이렇게 냉각수(W)와 직접 접촉 구성된 냉각수파이프(CWP)에 수용된 부동액냉각수는 상온상태의 열교환이 더욱 증대되는데 이때 파이프(P)내부에 구비된 냉매파이프(CP)에서 순환하고 있는 냉매가스는 냉각파이프(CP)의 초기단계 영역(A1)에서 -20℃정도의 온도를 유지하고 있어 상온상태로 회수되는 부동액냉각수를 냉각시키게 된다.The refrigerant gas circulating in the refrigerant pipe (CP) provided in the pipe (P) flows through the cooling pipe (CWP) provided in the pipe (P) The temperature of about -20 DEG C is maintained in the initial stage region A1 of the CP, thereby cooling the recovered antifreeze coolant in the normal temperature state.

이렇게 회수되는 부동액냉각수를 냉각시키는 냉매가스는 냉매파이프(FP)와 냉각수파이프(CWP) 사이에 구비된 파이프(P)에 의해 소정의 공간부(S)가 형성됨에 따라 해빙된 냉각수(W)에 의해 열교환된 부동액냉각수와의 접촉이 차단되므로서 중간단계의 영역(A1)과 후기단계의 영역(A3)으로 순환되는 냉매가스의 온도상승을 최대한 방지할 수 있게 한다.The refrigerant gas for cooling the recovered antifreezing cooling water is supplied to the cooling water W that is thawed as the predetermined space S is formed by the pipe P provided between the refrigerant pipe FP and the cooling water pipe CWP Exchanged by the refrigerant flowing into the intermediate region A1 and the later-stage region A3, the temperature rise of the refrigerant gas circulated to the intermediate region A1 and the later-stage region A3 can be prevented as much as possible.

따라서, 열교환기(HE)를 거쳐 회수되는 부동액냉각수는 냉각파이프(CP)에서 순환될 때 저온상태로 유지된 냉매가스에 의해 냉각효율이 크게 증대되므로 냉각수(W)의 해빙을 지연시키고, 동시에 냉각효율 증대시킴으로 인하여 따른 빙축식 냉방기(AC)의 냉방작동 시간을 크게 연장시킬 수 있게 한 것이다.Therefore, since the antifreeze cooling water recovered through the heat exchanger HE is greatly increased in cooling efficiency by the refrigerant gas maintained in a low temperature state when circulated in the cooling pipe CP, the thawing of the cooling water W is delayed, So that it is possible to greatly extend the cooling operation time of the ice-maker type cooler (AC).

이상에서와 같이 본 발명은 빙축식냉방기(또는 냉방기) 냉매파이프와 냉각수파이프 사이에 별도의 파이프를 구비하여 냉각파이프를 3중관으로 구성함에 따라 해빙된 냉각수에 접촉된 냉각수파이프의 부동액 냉각수와 냉매파이프가 직접 접촉되는 것을 방지함에 따라 냉매파이프 내의 냉매가스의 온도상승 변화를 방지하고,부동액냉각수의 냉각효율을 높이며, 결빙된 냉각수 해빙을 지연시키고, 빙축식 냉방기의 냉방기능 증대를 꾀할 수 있는 효과가 있다.As described above, according to the present invention, since a separate pipe is provided between the refrigerant pipe and the cooling water pipe of the ice-maker type cooling machine (or cooler) so that the cooling pipe is composed of a triple pipe, the antifreeze cooling water of the cooling water pipe contacted with the thawed cooling water, It is possible to prevent the temperature rise of the refrigerant gas in the refrigerant pipe from increasing, to increase the cooling efficiency of the freezing liquid cooling water, to delay the freezing of the freezing water, and to increase the cooling function of the ice- have.
