본 발명은 해수를 이용한 선박용 수냉식 냉난방 장치에 관한 것으로, 더욱 상세하게는 열교환 매체인 냉매를 저온의 해수와 열교환시켜 냉난방 효과를 확보할 수 있도록 한 해수를 이용한 선박용 수냉식 냉난방 장치에 관한 것이다.The present invention relates to a water-cooled cooling/heating device for a ship using seawater, and more particularly, to a water-cooled cooling/heating device for a ship using seawater, in which a refrigerant, which is a heat exchange medium, exchanges heat with low-temperature seawater to secure a cooling/heating effect.

일반적으로 선박의 선실 냉난방은 난방의 경우 선박을 운행하기 위해 구동되는 선박 엔진으로부터 방출되는 폐열을 이용하므로 별도의 에너지를 사용하지 않는 점에서 에너지를 절감할 수 있으나 엔진의 폐열을 이용하기 위한 별도의 배관설비를 해야되는 점에서 좁은 선박에서 설비의 시설을 하기가 용이하지 않고 비용이 많이 들어가는 문제점이 있었다.In general, the cabin heating and cooling of a ship uses waste heat emitted from a ship engine driven to operate a ship in the case of heating, so energy can be saved in that no separate energy is used. There was a problem in that it was not easy to install the facility in a narrow vessel in that it had to be equipped with a plumbing facility, and the cost was high.

또한, 냉방의 경우에는 별도의 냉방기를 설치해야 되는 경제적인 어려움이 뒤따른다. 근래에는 냉매를 이용하여 냉난방을 선택적으로 할 수 있는 히트펌프의 사용이 증가되고 있다. In addition, in the case of cooling, there is an economic difficulty in having to install a separate air conditioner. In recent years, the use of a heat pump capable of selectively heating and cooling using a refrigerant is increasing.

그러나 이러한 태양광의 직사광선을 직접적으로 많은 선박의 경우 기존의 히트펌프로서는 충분한 냉난방 효과를 얻을 수 없었을 뿐 아니라 대부분 냉매를 냉각시키는 열교환기가 공냉식이므로 에너지 수요가 과다하여 충분한 냉난방을 확보하지 못하면서 에너지 소비가 많아 매우 비경제적인 문제점이 있었다.However, in the case of a ship that receives a lot of direct sunlight from the sunlight, not only cannot obtain sufficient cooling and heating effect with conventional heat pumps, but most of the heat exchangers that cool the refrigerant are air-cooled. There was a very uneconomical problem.

본 발명은 이와 같은 종래의 문제점을 해결하고자 한 데 있는 것으로, 본 발명의 목적은 열교환 매체인 냉매를 저온으로서 일정한 온도를 가지는 해수를 이용하여 열교환시킴으로써 에너지 소모를 절감하면서 충분한 냉난방 효과를 얻을 수 있는 해수를 이용한 선박용 수냉식 냉난방 장치를 제공하는 데 있다. The present invention is intended to solve such conventional problems, and an object of the present invention is to heat exchange a refrigerant, which is a heat exchange medium, using seawater having a constant temperature as a low temperature, thereby reducing energy consumption and obtaining sufficient cooling and heating effect. An object of the present invention is to provide a water-cooled air conditioning system for ships using seawater.

도 1은 본 발명의 일 실시예에 따른 블록도1 is a block diagram according to an embodiment of the present invention;

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 일 실시예에 따른 블록도로서 본 발명의 해수를 이용한 선박용 수냉식 냉난방 장치(100)는 해수를 냉매의 열교환 매체를 사용하는 것으로 크게 압축기(10), 열교환기(20), 팽창밸브(30), 증발기(40), 사방밸브(50), 액분리기(60), 중앙제어기(70)를 포함하여 구성된다. 1 is a block diagram according to an embodiment of the present invention, in which a water-cooled air conditioning system 100 for a ship using seawater of the present invention uses seawater as a heat exchange medium of a refrigerant, and is largely a compressor 10, a heat exchanger 20, It is configured to include an expansion valve 30 , an evaporator 40 , a four-way valve 50 , a liquid separator 60 , and a central controller 70 .

상세하게는, 상기한 각 구성장치는 중앙제어기(70)에 제어되는 것으로, 상기 압축기(10)는 입구를 통해 내부로 유입된 냉매를 고온, 고압으로 압축하여 출구로 배출하는 역할을 하게 된다.In detail, each of the components described above is controlled by the central controller 70, and the compressor 10 serves to compress the refrigerant introduced into the interior through the inlet to high temperature and high pressure and discharge it to the outlet.

상기 열교환기(20)는 응축기의 역할을 수행하는 것으로 압축기(10)를 통해 나온 고온 고압의 기체를 냉매와 열교환하여 저온 저압 상태의 액체가 되도록 하는 것으로 본 발명은 상기 열교환기(20)를 해수를 열교환 매체로 사용하여 효율적으로 냉매를 저온 저압 상태로 유지하게 되는 것이다. The heat exchanger 20 serves as a condenser and heats the high-temperature and high-pressure gas discharged through the compressor 10 with a refrigerant to become a liquid in a low-temperature and low-pressure state. is used as a heat exchange medium to efficiently maintain the refrigerant in a low-temperature and low-pressure state.

상기 해수를 이용한 열교환기(20)는 유입라인과 배출라인으로 순환되는 냉매를 수용하는 쉘(냉매챔버)(31)과, 상기 쉘(31)의 내부에 녹이 슬지 않는 티타늄 소재로서 어느 하나의 입구를 통해 해수가 유입되어 다른 하나의 출구로 배출되는 코일(32)로 구성되는 쉘앤코일로 이루어진다. The heat exchanger 20 using the seawater has a shell (refrigerant chamber) 31 for accommodating the refrigerant circulated to the inlet line and the outlet line, and a titanium material that does not rust inside the shell 31, and is made of any one inlet. It consists of a shell and coil composed of a coil 32 that is introduced through the seawater and discharged to the other outlet.

상기 팽창밸브(30)는 좁은 곳을 통과하면 유체의 속도는 커지고 압력은 낮아지는 현상을 이용하여 모세관을 통과시켜 고압 상태의 액체 냉매의 압력을 낮추어 증발기(40)에서의 증발효과를 높이게 된다. When the expansion valve 30 passes through a narrow place, the speed of the fluid increases and the pressure decreases, so that it passes through a capillary tube to lower the pressure of the liquid refrigerant in a high pressure state, thereby increasing the evaporation effect in the evaporator 40 .

상기 증발기(40)는 팽창밸브(30)를 통과한 낮은 온도와 압력의 냉매가 실내의 더운 공기와 열교환되어 증발하면서 주변의 열을 흡수하여 주변의 공기를 차갑게 하며, 이때 찬 공기는 팬을 통하여 배출된다. The evaporator 40 cools the surrounding air by absorbing the surrounding heat as the refrigerant of low temperature and pressure that has passed through the expansion valve 30 exchanges heat with the hot air in the room and evaporates. is emitted

또한, 압축기(10)와 증발기(40)의 사이에는 냉매액과 냉매가스를 분리하는 액분리기(어큐뮬레이터)(60)가 설치되어 기체와 액체 상태로 분리된 냉매 중에서 기체상의 고온 처리된 냉매를 압축기(10)로 안내함으로써 압축기(10)를 보호하게 된다. In addition, a liquid separator (accumulator) 60 is installed between the compressor 10 and the evaporator 40 to separate the refrigerant liquid and the refrigerant gas. By guiding to (10), the compressor (10) is protected.

상기와 같이 구성된 해수를 이용한 선박용 에어컨은 압축기(10), 열교환기(응축기)(20), 팽창밸브(30), 증발기(40)가 냉매관을 매개로 연결되어 하나의 히트 펌프 사이클을 형성하게 되는 데, 요약하면, 압축기(10)에서 압축된 냉매가 액분리기(60)를 거쳐 열교환기(응축기)(20)로 이송되어 응축(방열)되고, 응축된 냉매는 팽창밸브(30)에서 팽창된 후에 증발기(흡열)(40)로 이송되며, 증발기(40)에서 냉매가 증발하면서 실내공기의 열을 빼앗아 냉방을 하고 흡열된 냉매는 다시 압축기(10)로 이송되어 기체 상태로 압축되는 것으로 냉매는 이와 같은 히트 펌프 사이클을 따라 순환하면서 응축과정에서 방열을 통해 실내 온도를 올리는 경우에는 난방이 되고 반대로 증발과정에서 실내 공기를 내리는 경우에는 냉방프로세스가 된다. In the air conditioner for ships using seawater configured as described above, a compressor 10, a heat exchanger (condenser) 20, an expansion valve 30, and an evaporator 40 are connected through a refrigerant pipe to form one heat pump cycle. In summary, the refrigerant compressed in the compressor 10 is transferred to the heat exchanger (condenser) 20 through the liquid separator 60 and condensed (radiated), and the condensed refrigerant is expanded in the expansion valve 30 . After cooling, the refrigerant is transferred to the evaporator (heat absorption) 40, and as the refrigerant evaporates in the evaporator 40, heat from the indoor air is taken away for cooling. is circulated along the heat pump cycle, heating when the indoor temperature is raised through heat dissipation in the condensation process and, conversely, a cooling process when the indoor air is lowered during the evaporation process.

본 발명의 냉난방장치는 선박의 실내에는 증발기(40)를 설치하고 실외에는 그외 장치를 설치하게 되는 데 열교환기(20)는 해수가 지속적으로 유입되고 유출되도록 설치되어 저온의 해수로서 냉매와 효율적으로 열교환을 하게 된다. In the air conditioning system of the present invention, the evaporator 40 is installed inside the ship and other devices are installed outdoors, and the heat exchanger 20 is installed so that seawater continuously flows in and out, so that it is effective with the refrigerant as low-temperature seawater. heat exchange takes place.

상기 열교환기(20)의 쉘앤코일은 일정크기의 챔버로 이루어진 쉘(31)의 내부에 냉각관을 코일(32) 형태로 감아 내장한 것으로 쉘(31)에는 냉매가 흐르고, 코일(32)의 내부에는 해수가 순환되도록 이루어진다. The shell-and-coil of the heat exchanger 20 has a cooling tube wound inside the shell 31 made of a chamber of a certain size in the form of a coil 32 and a refrigerant flows through the shell 31, and the It is made to circulate seawater inside.

따라서, 실내의 더운 공기와 열교환되어 증발된 후 흡열된 냉매가 압축기(10)에서 고온 고압의 기체 상태로 압축된 후 해수를 이용한 열교환기(20)의 쉘(31)로 이송되면 쉘(31)의 내부에 설치되어 해수가 유입 배출되는 저온의 코일(32)과의 열교환이 이루어져 액체로 응축되고 팽창밸브(30)에서 저압 상태로 팽창된 후 증발기(40)에서 냉매가 증발하면서 주변의 열을 흡수하여 냉방을 하게 되는 것으로 특히, 압축기(10)에서 압축된 냉매를 일정한 수온의 해수를 이용한 열교환기(20)에 의해 응축함으로써 열교환 효과를 높이게 되고 종래 공냉식에 비해 자연조건을 이용함에 따라 에너지를 절감하면서 냉난방 효율을 높이는 효과를 달성하게 된다. Therefore, when the refrigerant absorbed after heat exchange with the hot air in the room is evaporated and compressed into a gaseous state of high temperature and high pressure in the compressor 10 and transferred to the shell 31 of the heat exchanger 20 using seawater, the shell 31 Heat exchange with the low-temperature coil 32 installed in the inside of the evaporator is condensed into a liquid and expanded to a low pressure state in the expansion valve 30, and then the refrigerant evaporates in the evaporator 40 to reduce the surrounding heat. In particular, the refrigerant compressed in the compressor 10 is condensed by the heat exchanger 20 using seawater of a constant water temperature to increase the heat exchange effect, and energy is saved by using natural conditions compared to the conventional air cooling system. Savings can be achieved while increasing the cooling and heating efficiency.

본 발명의 해수를 이용한 열교환기(20)의 코일(32)은 비교적 해수에 오래 견디는 티타늄 소재로서 형성하여 부식 속도를 늦춤으로써 수명을 길게 하며, 해수는 태양열을 직접 흡수하는 혼합층보다는 수온이 평균 4℃로서 매우 낮고 대류가 일어나지 않아 안정한 수온약층의 해수를 사용하는 것이 바람직하며, 더 나아가 계절이나 깊이에 따른 수온변화가 거의 없고 수온약층보다 낮은 수온의 심해층의 해수를 사용할 수 있다.The coil 32 of the heat exchanger 20 using seawater of the present invention is formed of a titanium material that can withstand seawater for a long time, thereby slowing the corrosion rate and thus lengthening the lifespan. It is preferable to use seawater from the thermocline layer that is very low as ℃ and stable because convection does not occur, and furthermore, seawater from the deep sea layer having a lower water temperature than the thermocline layer can be used because there is little change in water temperature depending on season or depth.

또한, 본 발명은 사방밸브(50)의 전환에 의해 냉방모드와 난방모드를 겸할 수 있는 데 냉방모드에서는 사방밸브(50)에 의해 냉매의 흐름이 증발기(40)에서 압축기(10) 및 열교환기(20)로 이루어지고, 난방모드에서는 냉매의 흐름이 열교환기(20)에서 압축기(10) 및 증발기(40)로 이루어짐으로써 냉난방을 가능하게 한다.Also, in the present invention, the cooling mode and the heating mode can be combined by switching the four-way valve 50. In the cooling mode, the flow of refrigerant from the evaporator 40 to the compressor 10 and the heat exchanger is performed by the four-way valve 50. (20), and in the heating mode, the refrigerant flows from the heat exchanger (20) to the compressor (10) and the evaporator (40), thereby enabling heating and cooling.
