As shown in FIG. 1, a conventional cooling system 10 includes an air conditioner 12, a refrigerator 20, and a closed cooling water (CCW) circulation device 30. The conventional cooling system 10 is a cooling system 10 that cools the cooling water via the air conditioner 12 using only the refrigerator 20 regardless of the season.

공기조화기(12)는 주냉각수로(11) 및 냉각수 펌프(14)를 연결한다. 냉각수는 주냉각수로(11)의 내부에서 유동한다. 공기조화기(12)는 냉방 공간에 설치된다. 냉각수는 화살표 방향(FCW)을 따라 유동하여, 냉동기(20)를 경유한다. 냉각수는 냉동기(20)를 경유하면서, 냉매 열교환기(21)에서 냉매 순환로(24) 내의 냉매에 의해 냉각된다. 냉동기(20)를 경유하면서 냉각된 주냉각수로(11) 내의 냉각수는 냉각수 펌프(14)에서 가압된 후, 주냉각수로(11)를 통해 공기조화기(12)를 경유하면서, 냉방 공간의 공기를 냉각시킨다. 종래의 냉방 시스템(10)에서, 냉각수는 냉동기(20)의 냉매에 의해서만 냉각되었다. The air conditioner 12 connects the main cooling water passage 11 and the cooling water pump 14. Cooling water flows inside the main cooling channel 11. The air conditioner 12 is installed in a cooling space. The cooling water flows along the arrow direction F CW and passes through the freezer 20. The cooling water is cooled by the refrigerant in the refrigerant circulation path 24 in the refrigerant heat exchanger 21 while passing through the refrigerator 20. Cooling water in the main cooling water passage 11 cooled while passing through the refrigerator 20 is pressurized by the cooling water pump 14, and then the air in the cooling space while passing through the air conditioner 12 through the main cooling water passage 11. Cool down. In the conventional cooling system 10, the cooling water is cooled only by the refrigerant of the refrigerator 20.

한편, 냉동기(20)는 냉매 열교환기(21), 압축기(22), 압축기(22)를 작동시키는 모터(23) 및 냉매 순환로(24)를 포함한다. 냉매 순환로(24) 상에는, 냉매 열교환기(21) 및 압축기(22)가 위치된다. 압축기(22)는 모터(23)에 의해 작동하게 된다. The refrigerator 20 includes a refrigerant heat exchanger 21, a compressor 22, a motor 23 for operating the compressor 22, and a refrigerant circulation path 24. On the refrigerant circulation path 24, a refrigerant heat exchanger 21 and a compressor 22 are located. The compressor 22 is operated by the motor 23.

냉매 열교환기(21)는 냉매 순환로(24)를 포함하고, 압축기(22)에서 압축된 냉매는 화살표 방향(Fr)을 따라 냉매 순환로(24)를 유동하면서 주냉각수로(11) 내의 냉각수를 냉각시킨다. 한편, 주냉각수로(11)를 거치며 온도가 상승한 냉매 순환로(24) 내의 냉매는 제 2 CCW 순환로(32) 내의 폐쇄 냉각수로부터 냉열을 흡수하여 냉각된다. 제 2 CCW 순환로(32) 내의 폐쇄 냉각수와 열교환되어 냉각된 냉매는 냉매 순환로(24)를 통해 압축기(22)로 공급된다.The refrigerant heat exchanger 21 includes a refrigerant circulation path 24, and the refrigerant compressed by the compressor 22 flows the coolant in the main cooling water path 11 while flowing in the refrigerant circulation path 24 along the arrow direction F r . Cool. On the other hand, the refrigerant in the refrigerant circulation path 24 whose temperature rises through the main cooling water passage 11 is cooled by absorbing cold heat from the closed cooling water in the second CCW circulation path 32. The refrigerant cooled by heat exchange with the closed cooling water in the second CCW circulation path 32 is supplied to the compressor 22 through the refrigerant circulation path 24.

한편, 폐쇄 냉각수 순환 장치(30)는 제 1 CCW 순환로(31), 제 2 CCW 순환로(32), 온도조절밸브(33), 발전소 설비(34), 폐쇄 냉각수 펌프(35), 폐쇄 냉각수 열교환기(37) 및 해수 순환로(38)를 포함한다. 폐쇄 냉각수 순환 장치(30)에서, 해수 및 폐쇄 냉각수는 각각 화살표 방향(FSW, FCCW)을 따라 순환된다.On the other hand, the closed cooling water circulation device 30 is the first CCW circulation path 31, the second CCW circulation path 32, the temperature control valve 33, the power plant equipment 34, the closed cooling water pump 35, the closed cooling water heat exchanger (37) and seawater circulation path (38). In the closed cooling water circulation device 30, the sea water and the closed cooling water are circulated along the arrow directions F SW , FC CW , respectively.

제 1 CCW 순환로(31)는 폐쇄 냉각수 열교환기(37) 및 발전소 설비(34)를 경유하는 폐쇄 냉각수가 유동하는 배관이고, 제 2 CCW 순환로(32)는 온도조절밸 브(33)를 통과한 후 냉동기(20)를 경유한 폐쇄 냉각수가 발전소 설비(34)를 거친 폐쇄 냉각수와 합류되도록 유동하는 배관이고, 온도조절밸브(33)는 폐쇄 냉각수 열교환기(37)를 경유한 폐쇄 냉각수와 폐쇄 냉각수 펌프(35)에 의해 가압된 폐쇄 냉각수를 혼합하여 폐쇄 냉각수의 온도를 조절하는 밸브이다. 폐쇄 냉각수 열교환기(37)는 제 1 CCW 순환로(31) 내의 폐쇄 냉각수와 해수 순환로(38) 내의 해수를 열교환시켜, 폐쇄 냉각수를 냉각시키는 장치이다. The first CCW circulation path 31 is a pipe through which the closed cooling water flows through the closed cooling water heat exchanger 37 and the power plant facility 34, and the second CCW circulation path 32 passes through the temperature control valve 33. After that, the closed cooling water via the refrigerator 20 flows to join the closed cooling water through the power plant facility 34, and the temperature control valve 33 is the closed cooling water and the closed cooling water via the closed cooling water heat exchanger 37. A valve for controlling the temperature of the closed cooling water by mixing the closed cooling water pressurized by the pump 35. The closed cooling water heat exchanger 37 is a device that heat-exchanges the closed cooling water in the first CCW circulation path 31 and the seawater in the seawater circulation path 38 to cool the closed cooling water.

종래의 냉방 시스템(10)에서 폐쇄 냉각수의 흐름은 다음과 같다. 폐쇄 냉각수의 흐름은 화살표 방향(FCCW)을 따라 진행된다. In a conventional cooling system 10, the flow of closed cooling water is as follows. The flow of closed coolant proceeds in the direction of the arrow F CCW .

폐쇄 냉각수 열교환기(37)를 나온 폐쇄 냉각수는 제 1 CCW 순환로(31)를 통해 유동한다. 그러나, 너무 낮은 온도의 폐쇄 냉각수가 발전소 설비(34) 내에서 유동할 때, 발전소 설비의 손상이 야기된다. 이에 따라, 폐쇄 냉각수 열교환기(37)를 나온 폐쇄 냉각수는 온도조절밸브(33)에서 발전소 설비(34) 및 냉동기(20)를 경유하면서 온도가 상승한 폐쇄 냉각수와 혼합된다. The closed coolant exiting the closed coolant heat exchanger 37 flows through the first CCW circuit 31. However, when the closed cooling water at too low a temperature flows in the power plant equipment 34, damage to the power plant equipment is caused. Accordingly, the closed cooling water exiting the closed cooling water heat exchanger 37 is mixed with the closed cooling water whose temperature rises via the power plant equipment 34 and the freezer 20 in the temperature control valve 33.

온도조절밸브(33)에 의해 혼합된 폐쇄 냉각수는 화살표 방향(FCCW)을 따라 제 1 CCW 순환로(31)를 통해 발전소 설비(34)를 경유하거나, 제 2 CCW 순환로(32)를 통해 냉동기(20)를 경유한다. The closed coolant mixed by the temperature control valve 33 passes through the power plant facility 34 through the first CCW circulation path 31 along the arrow direction F CCW or through the second CCW circulation path 32. Via 20).

발전소 설비(34) 및 냉동기(20)를 경유한 폐쇄 냉각수는 폐쇄 냉각수 펌프(35)에 의해 가압된다. 이후, 가압된 폐쇄 냉각수의 일부는 제 1 CCW 순환로(31)를 통해 폐쇄 냉각수 열교환기(37)를 경유하고, 가압된 폐쇄 냉각수의 나머지 일부 는 발전소의 설비(34)를 보호하기 위해 폐쇄 냉각수 열교환기(37)에서 냉각된 폐쇄 냉각수와 혼합된다.The closed cooling water via the power plant equipment 34 and the refrigerator 20 is pressurized by the closed cooling water pump 35. Then, part of the pressurized closed coolant passes through the closed coolant heat exchanger 37 through the first CCW circulation path 31, and the remaining part of the pressurized closed coolant heats the closed coolant heat exchange to protect the plant 34 of the power plant. It is mixed with the closed cooling water cooled in machine 37.

또한, 상기와 같은 구성을 가진 종래의 냉방시스템(10)은 다음과 같은 단점이 존재한다. In addition, the conventional cooling system 10 having the above configuration has the following disadvantages.

일반적으로 환절기 및 동절기에는 대기 온도가 냉방 공간의 냉방 온도보다 떨어지는 경우가 많아, 냉방 공간의 냉방 부하가 하절기에 비해 급격히 떨어지기 때문에, 적은 양의 냉각수로도 냉방 공간을 냉방할 수 있다. 적은 양의 냉각수만으로도 냉방 공간을 냉방할 수 있음에도 불구하고, 모터(23)를 사용하여 압축기(22)를 가동함으로써 냉매를 압축하는 전기 압축 냉동 방식은 냉방 부하에 따라 모터(23)의 소비 전력을 조절할 수 없기 때문에, 냉방 부하에 관계없이 모터(23)는 일정한 소비전력을 사용하여 구동되는 문제점이 있다.In general, in the season and the winter season, the air temperature is often lower than the cooling temperature of the cooling space, and since the cooling load of the cooling space is sharply lower than in the summer season, the cooling space can be cooled even with a small amount of cooling water. Although the cooling space can be cooled with only a small amount of cooling water, the electric compression refrigeration method of compressing the refrigerant by operating the compressor 22 using the motor 23 reduces the power consumption of the motor 23 according to the cooling load. Since it cannot be adjusted, the motor 23 is driven using a constant power consumption regardless of the cooling load.

이에 따라, 종래의 냉방 시스템(10)은 전기를 절약하기 위하여, 공기조화기(12)를 순환하는 냉각수의 온도가 일정 온도 이하로 내려가면 모터(23)를 정지시켰으나, 이는 높은 전압으로 구동되는 모터(23)의 기동 정지가 반복됨에 따라 모터(23)의 고장 사례가 급증하였다. 또한, 이로 인해 모터(23)에 연결된 압축기(22)의 고장이 빈번하였다. Accordingly, in order to save electricity, the conventional cooling system 10 stops the motor 23 when the temperature of the coolant circulating the air conditioner 12 drops below a predetermined temperature, but it is driven at a high voltage. As the starting and stopping of the motor 23 was repeated, the failure cases of the motor 23 increased rapidly. In addition, this caused frequent failures of the compressor 22 connected to the motor 23.

아울러, 최근 녹색 운동 등 이산화탄소 감축문제가 국제적인 이슈로 대두되는 시점에서 자연에서 얻어지는 냉각수가 있음에도 불구하고, 연중 전기를 사용하여 압축냉동을 하는 것은 심각한 낭비이다.In addition, despite the fact that the cooling water is obtained from nature when the carbon dioxide reduction problem such as the green movement is emerging as an international issue, it is a serious waste to use the year-round electricity compression compression.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 제 1 목적은, 대기 온도가 공기조화기에서 운전되는 운전온도보다 떨어져 냉방 공간에서의 냉방 부하가 적게 요구되는 동절기 또는 환절기에는 냉동기의 사용없이도 냉각수 보조 열교환기에서 해수에 의해 냉각된 폐쇄 냉각수를 통해 냉각수를 냉각시킬 수 있는 해수 냉방 시스템을 제공함을 목적으로 한다.

도 2에 도시된 바와 같이, 본 발명인 해수 냉방 시스템(100)은 공기조화기(110), 주냉각수로(111), 보조 냉각수로(112), 전환 밸브(113), 냉동기(120), 폐쇄 냉각수 순환장치(130) 및 냉각수 보조 열교환기(140)를 포함한다. 본 발명인 해수 냉방 시스템(100)은 냉동기(120) 뿐 아니라 해수를 이용한 냉각수 보조 열교환기(140)를 사용하여 냉각수를 냉각시키는 냉방 시스템이다. As shown in FIG. 2, the present inventors' seawater cooling system 100 includes an air conditioner 110, a main cooling water passage 111, an auxiliary cooling water passage 112, a switching valve 113, a freezer 120, and a closed unit. Cooling water circulator 130 and the cooling water auxiliary heat exchanger (140). The seawater cooling system 100 of the present invention is a cooling system that cools the cooling water using the refrigerator 120 as well as the cooling water auxiliary heat exchanger 140 using the seawater.

공기조화기(110)는 공기조화기(110)를 순환하는 냉각수에 의해 공기를 냉각 시키는 장치이다. 공기조화기(110)는 냉방이 필요한 냉방 공간에 설치되어, 냉방 공간 내의 공기를 냉각시킨다. The air conditioner 110 is a device that cools the air by the coolant circulating in the air conditioner 110. The air conditioner 110 is installed in a cooling space that requires cooling to cool air in the cooling space.

본 실시예에서, 공기조화기(110)는 주냉각수로(111)를 통해, 보조 냉각수로(112), 전환 밸브(113) 및 냉각수 펌프(114)에 연결된다.In this embodiment, the air conditioner 110 is connected to the auxiliary cooling water channel 112, the switching valve 113 and the cooling water pump 114 through the main cooling water channel 111.

주냉각수로(111)는 공기조화기(110) 및 냉동기(120) 내의 냉매 열교환기(121)를 경유하여, 순환되는 구조를 가진다. 주냉각수로(111)의 내부에는 냉각수가 유동한다. The main cooling channel 111 has a structure circulated via the refrigerant heat exchanger 121 in the air conditioner 110 and the refrigerator 120. Cooling water flows inside the main cooling channel 111.

보조 냉각수로(112)는 공기조화기(110)를 경유한 냉각수를 냉동기(120)를 거치지 않고, 공기조화기(110)로 다시 유도하는 배관이다. 보조 냉각수로(112)는 냉각수 보조 열교환기(140)를 통과한다. The auxiliary cooling water path 112 is a pipe that guides the cooling water via the air conditioner 110 back to the air conditioner 110 without passing through the freezer 120. The auxiliary coolant passage 112 passes through the coolant auxiliary heat exchanger 140.

전환 밸브(113)는 주냉각수로(111)와 보조 냉각수로(112)에 연결된다. 전환 밸브(113)는 공기 조화기(110)를 경유한 냉각수를 냉동기(120) 또는 보조 냉각수로(112) 중 어느 하나로 유도하는 밸브이다. The switching valve 113 is connected to the main cooling channel 111 and the auxiliary cooling channel 112. The switching valve 113 is a valve that guides the cooling water via the air conditioner 110 to either the refrigerator 120 or the auxiliary cooling water path 112.

전환 밸브(113)는 냉방 공간의 냉방 부하가 낮은 동절기 또는 환절기 동안에는, 냉동기(120)를 경유하는 주냉각수로(111)로 유동하는 경로를 차단하는 반면, 보조 냉각수로(112)로 유동하는 경로를 선택하는 것이 바람직하다. 반면, 전환 밸브(113)는 냉방 공간에서의 냉방 부하가 높은 하절기 동안에는 냉동기(120)를 경유하는 주냉각수로(111)로 유동하는 경로를 선택하는 반면, 보조 냉각수로(112)로 유동하는 경로를 차단하는 것이 바람직하다. The changeover valve 113 blocks the flow path to the main cooling water passage 111 via the freezer 120 during the winter season or the change season when the cooling load of the cooling space is low, while the flow path flows to the auxiliary cooling water passage 112. It is preferable to select. On the other hand, the switching valve 113 selects a path that flows to the main cooling water passage 111 via the freezer 120 during the summer when the cooling load in the cooling space is high, while a path that flows to the auxiliary cooling water passage 112. It is desirable to block.

냉각수는 냉동기(120)의 작동시 전환 밸브(113)를 거쳐, 냉동기(120)를 경유 한다. 냉각수는 냉동기(120)를 경유하면서, 냉동기(120)의 냉매에 의해 냉각된다. 냉동기(120)를 경유하면서 냉각된 냉각수는 냉각수 펌프(114)에서 가압된 후, 주냉각수로(111)를 통해 공기조화기(110)를 경유하면서, 냉방 공간의 공기를 냉각시킨다. Cooling water passes through the freezer (120) via the switching valve 113 during the operation of the freezer (120). The cooling water is cooled by the refrigerant of the refrigerator 120 while passing through the refrigerator 120. The cooling water cooled while passing through the refrigerator 120 is pressurized by the cooling water pump 114, and then cools the air in the cooling space while passing through the air conditioner 110 through the main cooling water path 111.

한편, 냉각수 보조 열교환기(140)의 작동시 냉각수는 전환 밸브(113)를 통해 화살표 방향(FCW)을 따라 유동하여, 냉각수 보조 열교환기(140)를 경유한다. 냉각수는 냉각수 보조 열교환기(140)를 경유하면서, 냉각수 보조 열교환기(140)를 경유하는 폐쇄 냉각수 순환로(136) 내의 폐쇄 냉각수와 열교환하여 냉각된다. 여기서, 냉각수 보조 열교환기(140)를 경유하는 폐쇄 냉각수는 폐쇄 냉각수 열교환기(137)에서 해수에 의해 냉각되므로 추가적인 냉각 설비 없이도 냉각수를 냉각할 수 있는 폐쇄 냉각수를 얻게 된다.Meanwhile, when the coolant auxiliary heat exchanger 140 is operated, the coolant flows along the arrow direction F CW through the switching valve 113 and passes through the coolant auxiliary heat exchanger 140. The coolant is cooled by heat exchange with the closed coolant in the closed coolant circulation path 136 via the coolant auxiliary heat exchanger 140 while passing through the coolant auxiliary heat exchanger 140. Here, the closed cooling water via the cooling water auxiliary heat exchanger 140 is cooled by sea water in the closed cooling water heat exchanger 137, thereby obtaining a closed cooling water capable of cooling the cooling water without additional cooling facilities.

냉각수 보조 열교환기(140)를 경유하면서 냉각된 냉각수는 냉각수 펌프(114)에서 가압된 후, 주냉각수로(111)를 통해 공기조화기(110)를 통과한다. 이때, 냉각수는 냉방 공간의 공기의 열을 흡수하여 공기를 냉각시킨다. 다만, 하절기에는, 냉각수는 종래의 냉방 시스템과 동일한 방식으로 냉동기(120)에서 냉각된다.The cooling water cooled while passing through the cooling water auxiliary heat exchanger 140 is pressurized by the cooling water pump 114 and then passes through the air conditioner 110 through the main cooling water path 111. At this time, the cooling water absorbs the heat of the air in the cooling space to cool the air. However, in summer, the coolant is cooled in the refrigerator 120 in the same manner as the conventional cooling system.

The refrigerant heat exchanger 121 includes a refrigerant circulation path 124, a main cooling water path 111, and a second CCW circulation path 132. In the refrigerant heat exchanger 121, the closed cooling water of the second CCW circulation path 132 is mutually heat exchanged with the refrigerant in the refrigerant circulation path 124, and the cooling water of the main cooling water path 111 is connected to the refrigerant in the refrigerant circulation path 124. Mutual heat exchange takes place.

냉매 열교환기(121)에서 압축기(122)에서 압축된 냉매는 화살표 방향(Fr)을 따라 냉매 순환로(124)를 유동하면서 주냉각수로(111) 내의 냉각수를 냉각한다. 한편, 주냉각수로(111)와 열교환에 의해 온도가 상승한 냉매 순환로(124) 내의 냉매는 제 2 CCW 순환로(132) 내의 폐쇄 냉각수로부터 냉열을 흡수하여 냉각된다. 제 2 CCW 순환로(132) 내의 폐쇄 냉각수와 열교환되어 냉각된 냉매는 냉매 순환로(124)를 통해 압축기(122)로 공급된다. 한편, 압축기(122)는 모터(123)에 연결되어, 모터(123)에 의해 작동된다. The refrigerant compressed by the compressor 122 in the refrigerant heat exchanger 121 cools the cooling water in the main cooling channel 111 while flowing in the refrigerant circulation path 124 along the arrow direction F r . On the other hand, the refrigerant in the refrigerant circulation path 124 whose temperature has risen due to heat exchange with the main cooling water path 111 absorbs cold heat from the closed cooling water in the second CCW circulation path 132 and is cooled. The refrigerant cooled by heat exchange with the closed cooling water in the second CCW circulation path 132 is supplied to the compressor 122 through the refrigerant circulation path 124. On the other hand, the compressor 122 is connected to the motor 123, and is operated by the motor 123.

The temperature control valve 133, the power plant equipment 134, the closed coolant pump 135, and the closed coolant heat exchanger 137 are sequentially positioned on the first CCW circulation path 131. The closed cooling water in the first CCW circulation path 131 passes through the power plant equipment 134, the refrigerator 120, and the cooling water auxiliary heat exchanger 140 along the respective arrow directions F CCW1 , F CCW2 , F CCW5 . Subsequently, the closed cooling water in the first CCW circulation path 131 flows into the closed cooling water heat exchanger 137 along the arrow direction F CCW4 and is cooled by heat exchange with the seawater in the seawater circulation path 138. The flow of the closed cooling water will be described later.

제 2 CCW 순환로(132)는 냉동기(120)를 경유한 폐쇄 냉각수가 유동하는 배관이다. 제 2 CCW 순환로(132)는 온도조절밸브(133)와 발전소 설비(134) 사이에서, 제 1 CCW 순환로(131)와 연결된다. 제 2 CCW 순환로(132) 내의 폐쇄 냉각수는 온도조절밸브(133)를 거친 폐쇄 냉각수이며, 제 2 CCW 순환로(132)를 통해 냉동기(120)의 냉매 열교환기(121)를 경유한다. The second CCW circulation path 132 is a pipe through which the closed coolant flows through the freezer 120. The second CCW circulation path 132 is connected to the first CCW circulation path 131 between the temperature control valve 133 and the power plant equipment 134. The closed cooling water in the second CCW circulation path 132 is the closed cooling water passing through the temperature control valve 133 and passes through the refrigerant heat exchanger 121 of the refrigerator 120 through the second CCW circulation path 132.

온도조절밸브(133)는 폐쇄 냉각수 열교환기(137)를 경유한 폐쇄 냉각수와 폐쇄 냉각수 펌프(135)에 의해 가압된 폐쇄 냉각수를 혼합하여 폐쇄 냉각수의 온도를 조절하는 밸브이다. 즉, 온도조절밸브(133)는 폐쇄 냉각수 열교환기(137)를 통과한 저온의 폐쇄 냉각수(FCCW4-FCCW5)와 폐쇄 냉각수 열교환기(137)를 통과하지 않은 고온의 폐쇄 냉각수(FCCW3)를 혼합한다.

In addition, the closed cooling water circulation path 136 is connected to the first CCW circulation path 131 between the closed cooling water pump 135 and the closed cooling water heat exchanger 137, so that a portion of the closed cooling water F CCW5 in the closed cooling water circulation path 136 is provided . After passing through the coolant auxiliary heat exchanger 140, the cooling water heat exchanger 137 is joined to a part of the closed coolant F CCW1 + F CCW2 -F CCW3 via the power plant facility 134 and the freezer 120. To get into By the closed cooling water circulation path 136, the loss of cold heat in the process of passing through the temperature control valve 133, can be prevented, the cooling water can be cooled by using the closed cooling water cooled through the cold heat of sea water as it is.

폐쇄 냉각수 열교환기(137)는 바다에서 취수한 심층 해수가 유동되는 해수 순환로(138) 및 제 1 CCW 순환로(131)를 포함한다. 폐쇄 냉각수 열교환기(137)는 제 1 CCW 순환로(131) 내의 폐쇄 냉각수와 해수 순환로(138) 내의 해수를 열교환시켜, 폐쇄 냉각수를 냉각시키는 장치이다. 일반적으로, 바다 심층에서 취수된 해수의 온도는 연중 7개월 동안, 즉, 하절기를 제외한 환절기 및 동절기 동안, 15℃ 이하로 유지된다. 해수는 화살표 방향(FSW)을 따라 해수 순환로(138) 내부를 유동한다. The closed cooling water heat exchanger 137 includes a seawater circulation path 138 and a first CCW circulation path 131 through which deep seawater taken from the sea flows. The closed cooling water heat exchanger 137 is a device that heat-exchanges the closed cooling water in the first CCW circulation path 131 and the seawater in the seawater circulation path 138 to cool the closed cooling water. In general, the temperature of seawater withdrawn from deep seas is kept below 15 ° C. for seven months of the year, ie during the transitional and winter seasons except summer. The seawater flows inside the seawater circulation path 138 along the arrow direction F SW .

냉각수 보조 열교환기(140)는 폐쇄 냉각수 순환로(136) 및 보조 냉각수로(112)를 포함한다. 냉각수 보조 열교환기(140)는 폐쇄 냉각수 순환로(136) 내의 폐쇄 냉각수와 보조 냉각수로(112) 내의 냉각수를 열교환시킨다. 공기조화기(110) 를 경유한 냉각수의 온도가 폐쇄 냉각수의 온도보다 상대적으로 높기 때문에, 냉각수는 폐쇄 냉각수에 의해 냉각된다. The cooling water auxiliary heat exchanger 140 includes a closed cooling water circulation path 136 and an auxiliary cooling water path 112. The cooling water auxiliary heat exchanger 140 heat-exchanges the cooling water in the auxiliary cooling water path 112 with the closed cooling water in the closed cooling water circulation path 136. Since the temperature of the cooling water via the air conditioner 110 is relatively higher than the temperature of the closed cooling water, the cooling water is cooled by the closed cooling water.

냉각수 보조 열교환기(140)에서 냉각된 냉각수는 보조 냉각수로(112)를 거쳐, 주냉각수로(111)를 통해 공기조화기(110)를 통과한다. 한편, 냉각수 보조 열교환기(140)를 통과한 폐쇄 냉각수는 폐쇄 냉각수 순환로(136)를 통해, 폐쇄 냉각수 열교환기(137)로 유입된다. The cooling water cooled by the cooling water auxiliary heat exchanger 140 passes through the auxiliary cooling water passage 112 and passes through the air conditioner 110 through the main cooling water passage 111. On the other hand, the closed coolant passing through the coolant auxiliary heat exchanger 140 flows into the closed coolant heat exchanger 137 through the closed coolant circulation path 136.

이하에서는, 공기조화기(110), 냉동기(120) 및 폐쇄 냉각수 순환 장치(130) 및 냉각수 보조 열교환기(140)를 순환하는 냉각수, 냉매 및 폐쇄 냉각수의 흐름에 대해 살표보기로 한다. Hereinafter, the flow of the coolant, the coolant, and the closed coolant circulating in the air conditioner 110, the freezer 120, the closed coolant circulator 130, and the coolant auxiliary heat exchanger 140 will be illustrated.

우선, 냉각수의 흐름은 다음과 같다. First, the flow of cooling water is as follows.

공기조화기(110)를 나온 냉각수는 화살표 방향(FCW)을 따라, 전환 밸브(113)로 유입된다. 전환 밸브(113)는 하절기에는 냉동기(120)를 경유하는 주냉각수로(111)의 경로를 허용하므로, 주냉각수로(111) 내의 냉각수는 냉매 순환로(124)를 순환하는 냉매에 의해 냉각된다. 냉매에 의해 냉각된 냉각수는 주냉각수로(111)를 통해 냉각수 펌프(114)에서 가압되어 공기조화기(110)로 유입된다. Cooling water exiting the air conditioner 110 flows into the switching valve 113 along the arrow direction F CW . Since the switching valve 113 allows a path of the main cooling channel 111 via the freezer 120 in the summer, the cooling water in the main cooling channel 111 is cooled by the refrigerant circulating in the refrigerant circulation path 124. The cooling water cooled by the refrigerant is pressurized by the cooling water pump 114 through the main cooling water passage 111 and introduced into the air conditioner 110.

반면, 동절기 또는 환절기에는 전환 밸브(113)는 냉동기(120)를 경유하는 주냉각수로(111) 내의 경로를 차단하는 반면, 보조 냉각수로(112)로의 경로를 허용하므로, 보조 냉각수로(112) 내의 냉각수는 냉각수 보조 열교환기(140)에서, 폐쇄 냉 각수 순환로(136) 내의 폐쇄 냉각수와 열교환되어 냉각된다. 냉각수 보조 열교환기(140)에서 냉각된 냉각수는 주냉각수로(111)를 통해 냉각수 펌프(114)에서 가압되어 공기조화기(110)로 유입된다. On the other hand, during the winter season or the change season, the switching valve 113 blocks the path in the main cooling water passage 111 via the freezer 120, while allowing the path to the auxiliary cooling water passage 112, and thus, the auxiliary cooling water passage 112. The cooling water in the heat exchanged with the closed cooling water in the closed cooling water circulation path 136 in the cooling water auxiliary heat exchanger 140 is cooled. The cooling water cooled by the cooling water auxiliary heat exchanger 140 is pressurized by the cooling water pump 114 through the main cooling water path 111 and introduced into the air conditioner 110.

주냉각수로(111)를 통해 공기조화기(110)를 경유하는 냉각수는 냉방 공간 내의 공기를 냉각시킨다. 이후, 공기조화기(110)를 나온 냉각수는 다시 전환 밸브(113)로 유입된다. The cooling water passing through the air conditioner 110 through the main cooling channel 111 cools the air in the cooling space. Thereafter, the cooling water exiting the air conditioner 110 flows back into the switching valve 113.

냉매의 흐름은 다음과 같다.The flow of refrigerant is as follows.

압축기(122)에서 압축된 냉매는 화살표 방향(Fr)을 따라 냉매 순환로(124) 내에서 유동한 후, 압축기(122)로 다시 되돌아 온다. 압축기(122)에서 배출된 냉매는 주냉각수로(111)를 거치면서 냉각수의 열을 흡수하여 냉각수를 냉각시킨다. 이후, 냉매는 제 2 CCW 순환로(132)를 유동하는 폐쇄 냉각수의 냉열을 흡수하여 냉각된 후, 압축기(122)로 되돌아 간다.The refrigerant compressed in the compressor 122 flows in the refrigerant circulation path 124 along the arrow direction F r , and then returns to the compressor 122 again. The refrigerant discharged from the compressor 122 absorbs heat of the cooling water while passing through the main cooling water path 111 to cool the cooling water. Thereafter, the refrigerant absorbs the cold heat of the closed cooling water flowing through the second CCW circulation path 132 and is cooled, and then returns to the compressor 122.

The remaining portion of the closed coolant in the closed coolant circulation device 130 passing through the temperature control valve 133 passes through the freezer 120 through the second CCW circulation path 132 along the arrow direction F CCW2 . The closed cooling water in the second CCW circulation path 132 exchanges heat with the refrigerant in the refrigerant circulation path 124.

발전소 설비(134) 및 냉동기(120)를 경유한 폐쇄 냉각수는 합류한 뒤 폐쇄 냉각수 펌프(135)에 의해 가압된다. 이후, 폐쇄 냉각수 펌프(135)에 의해 가압된 폐쇄 냉각수의 일부는 화살표 방향을 따라(FCCW3) 온도조절밸브(133)로 유입되고, 나머지 일부는 화살표 방향(FCCW4)을 따라 폐쇄 냉각수 열교환기(137) 내로 유입되어, 폐쇄 냉각수 열교환기(137)에서 해수와 열교환하여 냉각된다. Closed cooling water via power plant equipment 134 and freezer 120 are joined and then pressurized by closed cooling water pump 135. Then, the portion of the closed cooling water pressurized by closing the cooling water pump 135 flows into (F CCW3), temperature control valve 133, along the direction of the arrow, and the other part is the direction of the arrow (F CCW4) a closed cooling water heat exchanger according It flows into 137 and heat-exchanges with sea water in the closed cooling water heat exchanger 137, and it cools.
