Description

빙축열 냉방시스템 및 방법{Cooling room system and method of ice water accumulation type}    Cooling room system and method of ice water accumulation type

본 발명은 빙축열을 이용한 냉방시스템 및 방법에 관한 것이다. The present invention relates to a cooling system and method using ice heat storage.

빙축열냉방시스템은 심야의 값싼 전기를 이용하여 낮시간 동안의 냉방을 가능하게 하는 냉방시스템의 일종으로서, 심야에 냉동기를 가동시켜서 얼음을 얼리고, 이를 보존하였다가 낮시간에 이 얼음을 이용하여 냉방을 하는 축열식 열교환시스템을 말한다.Ice heat storage cooling system is a type of cooling system that enables cooling during the daytime by using low-cost electricity at night.It operates a freezer in the middle of the night to freeze ice and preserves it. Refers to a regenerative heat exchange system.

국가적으로는 전력수요의 격차를 줄일 수 있고, 개인적으로는 주간요금의 1/4 수준인 심야전력을 사용하기 때문에 냉방시스템의 운영비를 대폭 절감할 수 있는 것이다.      Nationally, the gap in power demand can be narrowed, and personally, the use of midnight power, which is about 1/4 of the weekly rate, can drastically reduce the operating cost of the cooling system.

또한, 빙축열냉방시스템은 다른 냉방시스템에 비해 연속적으로 정격용량의 운전이 가능하여 시스템이 매우 안정적이고, 고효율이며, 얼음을 축열의 매개체로 사용하는 에너지절약형의 환경친화적인 냉방시스템이므로 최근 매우 각광받는 첨단 의 냉방시스템이다.      In addition, the ice storage cooling system is continuously stable compared to other cooling systems, so the system is very stable, high efficiency, and energy-saving environment-friendly cooling system that uses ice as a medium for heat storage. It is an advanced cooling system.

이러한 빙축열냉방시스템의 원리는 먼저 값싼 심야전력을 사용하여 심야시간대(22:00 ~ 08:00)에 냉동기를 가동하여 부동액을 냉각시키고, 이를 다수개의 축열구가 수용된 축열조에 통과시켜서 상기 축열구에 담긴 결빙액을 얼음 상태로 얼린다.      The principle of this ice heat storage cooling system is to operate the freezer in the late night time (22:00 ~ 08:00) by using a cheap night power to cool the antifreeze, and then pass it through the heat storage tank accommodating a plurality of heat storage ports to the heat storage mouth. Freeze frozen ice in ice.

이어서, 상기 냉동기를 멈추고, 낮시간이 되면, 상기 축열조를 통과하면서 상기 얼음 상태의 결빙액에 의해 차가워진 부동액의 냉기를 열교환기를 통해 물 또는 공기에 전달시켜서 건물을 냉방시킴으로써 주간의 최대부하시 냉방전력의 사용을 줄이거나 피할 수 있게 하는 것이다.      Then, the refrigerator is stopped, and during the day time, the coolant of the antifreeze cooled by the ice-freezing liquid is passed through the heat storage tank to the water or air through a heat exchanger to cool the building to cool the maximum load during the day. To reduce or avoid the use of power.

도 1은 종래의 빙축열냉방시스템의 일예를 도시한다.       1 shows an example of a conventional ice heat storage cooling system.

도 1의 공냉식 냉동장치는 공냉식 냉동기(1)로서 축열조(2)에 냉매배관(3)을 연결하여 냉매를 순환시키면서 축열조(2)에 얼음을 얼리기 위한 기기의 장치이다. 축열조(2)는 냉동기(1)에서 공급되는 저온저압의 냉매를 공급 받아 축열조(2) 내부에 저장되어 있는 물에 냉열을 빼앗기고 냉매는 고온의 열을 얻어 관을 통하여 냉동기(1)로 돌아가고 축열조(2)에 들어 있는 물은 계속 열을 빼앗겨 얼음으로 변하면서 영하의 얼음으로 빙축된다.       1 is an apparatus of an apparatus for freezing ice in the heat storage tank 2 while circulating the refrigerant by connecting the refrigerant pipe 3 to the heat storage tank 2 as the air-cooled refrigerator 1. The heat storage tank 2 receives the low temperature and low pressure refrigerant supplied from the freezer 1 to deprive the cold heat of the water stored in the heat storage tank 2, and the refrigerant obtains high temperature heat and returns to the freezer 1 through the pipe. The water in (2) continues to lose heat and turn into ice, ice-cold to sub-zero ice.

빙축된 얼음은 냉방기로부터 약12℃정도의 냉수를 냉수배관(5)을 통하여 공급받아 5℃정도의 냉수가 될 때까지 열을 흡수하고 냉수는 5℃까지 열을 빼앗겨 축열조(2)에서 냉수배관(5)를 통하여 냉방기(7)로 되돌려 보낸다. 축열조에는 이렇게 얼음을 얼리는 냉매코일(4) 장치와 얼음을 녹이는 장치 즉, 빙축열과 해빙의 방식 이 갖추어져 있는 것을 말한다.       The iced ice receives cold water of about 12 ℃ from the air conditioner through the cold water pipe (5), absorbs heat until it becomes cold water of about 5 ℃, and cold water is deprived of heat up to 5 ℃, so the cold water pipe in the heat storage tank (2) Return to the air conditioner (7) through (5). The heat storage tank is equipped with a refrigerant coil (4) device for freezing ice and a device for melting ice, that is, ice storage and thawing.

냉방기(7)는 냉방을 필요로 하는 실내에 배치되어 냉수배관(5)을 축열조(2)와 연결되고 연결 배관에는 냉수순환펌프(6)가 설치되어 냉방기(7)에 축열조(2)로부터 약 5℃의 냉수를 공급받아 냉방기 내부에 설치된 열교환용 냉수 코일(11)을 통과한 후 약 12℃ 정도로 온도가 상승되어 축열조로 되돌려 보낸다.      The air conditioner (7) is arranged in a room that needs cooling, and connects the cold water pipe (5) with the heat storage tank (2), and the cold water circulation pump (6) is installed in the connection pipe, so that the air conditioner (approximately) from the heat storage tank (2). After receiving cold water of 5 ° C. and passing through the cold water coil 11 for heat exchange installed in the air conditioner, the temperature is raised to about 12 ° C. and returned to the heat storage tank.

이때 냉방기의 전원부(12)에서 냉방기(7)을 가동하면 송풍기(8)가 가동되면서 실내의 공기를 흡입하여 냉수코일(11)외부를 지나도록 하여 차가운 공기로 변하여 공기 토출구를 통하여 실내로 보내짐으로서 냉방이 이루어진다.       At this time, when the air conditioner (7) is operated in the power supply unit 12 of the air conditioner, the blower (8) is operated to inhale the air in the room to pass through the cold water coil (11) to turn into cold air is sent to the room through the air discharge port As the cooling is achieved.

그러나 이방식은 냉동기(1)와 축열조(2)는 냉매배관(3)으로 연결되어 있고 축열조(2)와 냉방기(7)는 냉수배관(5)으로 연결되어 냉수순환펌프(6)가 설치되어 있어 모든 기기류는 한번 설치하면 변경하기가 곤란하며 축열조(2)에는 100% 냉동축열이 곤란하므로(약50% 정도인) 0℃이하의 즉, 저온 빙축열이 되지 아니하고 내부에 냉매코일이 들어가므로 축열조(2)의 외형이 크게 소요되며 생산비용 또한 많이 소요된다.      However, in this method, the refrigerator 1 and the heat storage tank 2 are connected to the refrigerant pipe 3, and the heat storage tank 2 and the cooler 7 are connected to the cold water pipe 5 so that the cold water circulation pump 6 is installed. It is difficult to change all the equipment once installed and the storage tank 2 does not have 100% refrigerated heat storage (approximately 50%). The appearance of 2) is large and the production cost is also high.

냉방기(7)에는 냉수코일(11)이 내장되어 냉수배관(5)에서 냉수순환펌프(6)에 의하여 냉수를 공급받아 돌아가도록 되어 있는데 강제순환이므로 순환모터 전력이 소모되고 냉수코일(11) 외부에는 핀이 부착되어 공기를 순환할 때 송풍기(8)의 정압이 손실이 생겨 전력 소모가 증대됨은 물론이고 냉방균이 서식할 수 있는 위생적 측면에 또한 문제점을 가지고 있다. 약간에 시설 변경 또는 이설 하려면 냉매가스, 냉매배관, 냉수순환배관, 보온재, 배관부속 부자재등 상당한 폐자재가 발생하게 되 는 문제점이 있었다.      In the air conditioner (7), the cold water coil (11) is built in and is supplied with cold water by the cold water circulation pump (6) from the cold water pipe (5), and it is forced circulation, so the circulation motor power is consumed and the cold water coil (11) outside There is also a problem in the hygienic aspect in which cooling pressure may inhabit as well as the power consumption is increased due to the loss of the static pressure of the blower 8 when the pin is attached to circulate the air. To change or relocate the facility slightly, there was a problem that considerable waste materials such as refrigerant gas, refrigerant piping, cold water circulation piping, insulation, and pipe fittings were generated.

따라서, 본 발명의 목적은 전술한 문제점을 해결할 수 있도록 별도의 배관이 필요 없이 하나의 패키지에 냉동기와 축열조를 구비하여 냉방이 가능한 냉방시스템의 소형화와 경량화 및 모듈화를 구현하여 하나의 시스템으로 빙축열을 이용한 냉방이 가능하도록 하는 빙축열 냉방시스템 및 방법을 제공함에 있다.Accordingly, an object of the present invention is to provide ice storage heat storage in one system by miniaturizing, lightweighting, and modularizing a cooling system capable of cooling by providing a freezer and a heat storage tank in one package so as to solve the above-mentioned problems without the need for a separate pipe.

In addition, the heat storage tank is characterized in that it comprises a rod-shaped heat storage rod formed with irregularities on the side and a heat storage donut through the insertion hole in the inner center so that the heat storage rod is inserted and the uneven portion is formed on the side.

본 발명에 따른 냉방방법은 하나의 하우징내부에 냉동밸브를 갖는 냉동기와 복수개의 축열도넛을 포함하는 축열조 및 팬을 구비하는 열교환기를 일체로 구성하 며 일측에 공기송풍구와 공기냉풍구를 이용해 빙축열을 이용해 냉방하는 냉방방법에 있어서, 빙축모드인지를 판단하는 단계; 상기 판단결과 빙축모드이면, 냉동밸브를 온하는 단계; 상기 냉동밸브에 의해 축열조와 냉동기간의 저온냉매가 순환하는 단계: 상기 저온냉매에 의해 축열조에 얼음이 저장완료되는 단계; 상기 판단결과 빙축모드가 아니면, 냉방모드로 전환하는 단계; 냉수순환펌프를 온하여 냉수가 상기 축열조와 열교환기 간을 순환하는 단계; 팬을 작동시킴과 동시에 공기송풍구와 공기냉풍구를 오픈하는 단계; 및 상기 순환되는 냉수에 의해 차가워진 공기를 상기 공기냉풍구를 통해 배출하는 단계를 포함하는 것을 특징으로 한다.       The cooling method according to the present invention comprises a heat exchanger having a refrigerating tank having a refrigeration valve and a plurality of heat storage donuts and a fan in one housing, and a fan and an air blower and an air cooling blower on one side.

이하, 첨부한 도 2 내지 도 5를 참조하여 본 발명의 바람직한 실시예를 상세히 기술하기로 한다. Hereinafter, with reference to the accompanying Figures 2 to 5 will be described in detail a preferred embodiment of the present invention.

도 2 및 도 3은 본 발명의 빙축열냉각시스템에 적용된 축열구조를 설명하기 위한 도면이다.       2 and 3 are views for explaining a heat storage structure applied to the ice heat storage cooling system of the present invention.

도 2는 본 발명에 적용된 축열도넛의 구성상태도이다.      2 is a configuration diagram of a heat storage donut applied to the present invention.

도 2를 참고하면, 축열도넛(60)은 축열봉이 삽입되도록 내측 중앙에 삽입공(61)이 관통되고 측부에 요철(62)이 형성된다. 축열도넛의 삽입공(61)은 축열봉의 지름보다 큰 내경으로 이루어져 축열도넛에 축열봉이 용이하게 삽입되면서 축열도넛의 삽입공 내측면도 부동액이 접촉될 수 있도록 한다. 요철은 나선형이 아닌 다수의 원형상의 고리모양으로 형성된다. 축열도넛의 측부에 다수의 요철이 형성되어 부동액의 접촉면적을 증가시킨다.      Referring to FIG. 2, the heat storage donut 60 has an insertion hole 61 penetrated through the inner center thereof so that the heat storage rod is inserted therein, and an unevenness 62 is formed at the side thereof. The insertion hole 61 of the heat storage donut has an inner diameter larger than the diameter of the heat storage rod so that the heat storage rod can be easily inserted into the heat storage donut so that the antifreeze can also contact the inner surface of the heat storage donut. The unevenness is formed in a plurality of circular rings rather than spirals. A large number of irregularities are formed on the side of the heat storage donut to increase the contact area of the antifreeze.

축열도넛에는 상하부에 다수의 이격돌기(63)가 돌출 형성되어 부동액의 접촉면적을 증가시킨다. 이격돌기는 축열도넛과 축열도넛 사이를 이격시킨다.In the heat storage donut, a plurality of spacers 63 protrude from the upper and lower portions to increase the contact area of the antifreeze. The spacers space between the heat accumulating donuts and the heat accumulating donuts.

축열구조는 축열봉이 하나 이상의 축열도넛에 삽입된다. The heat storage structure has a heat storage rod inserted into one or more heat storage donuts.

도 3은 도 2의 축열도넛이 그룹화프레임에 탑재된 축열구조의 사시도이다.      3 is a perspective view of a heat storage structure in which the heat storage donut of FIG. 2 is mounted on a grouping frame.

도 3에서 보는 바와 같이 축열봉이 하나 이상의 축열도넛에 삽입된 형태가 그룹화 되도록 그룹화프레임(70)에 다수 탑재된다.      As shown in FIG. 3, a plurality of heat storage rods are mounted on the grouping frame 70 to group the shapes of the heat storage rods inserted into the one or more heat storage donuts.

그룹화프레임(70)은 봉형상의 축열봉에 삽입된 도넛형상의 축열도넛을 축열조에 다수 충진하기 위해 운반 및 배열에 용이하도록 한다. 그룹화프레임(70)은 프레임(71)에 의해 육면체를 이루고, 프레임구조의 측부 4면에 강선(72)이 X모양으로 설치된다.      The grouping frame 70 facilitates carrying and arranging a plurality of donut-shaped heat storage donuts inserted into a rod-shaped heat storage rod in a heat storage tank. The grouping frame 70 forms a hexahedron by the frame 71, and the steel wire 72 is provided in an X shape on four sides of the frame structure.

도 3에서 보는 바와 같이 그룹화프레임(70)에 탑재된 축열도넛들 사이에 축열볼(80)이 충진되어 부동액의 접촉면적을 증가시킨다. 축열볼(80)의 직경은 그룹 화프레임에 탑재된 축열도넛의 사이공간의 크기보다 작게 형성됨이 바람직하다. 여기서 축열도넛들 사이에 축열볼 대신 축열봉이 삽설될 수도 있다.      As shown in FIG. 3, the heat storage ball 80 is filled between the heat storage donuts mounted on the grouping frame 70 to increase the contact area of the antifreeze. The diameter of the heat storage ball 80 is preferably formed smaller than the size of the space between the heat storage donuts mounted on the grouping frame. Here, the heat storage rod may be inserted between the heat storage donuts instead of the heat storage balls.

이러한, 축열봉, 축열도넛 그리고 축열볼은 내부에 결빙액이 충진되는 축열구조이다.      The heat storage rod, heat storage donut, and heat storage ball have a heat storage structure in which freezing liquid is filled therein.

이러한 축열봉의 요철, 축열도넛의 요철, 축열볼에 의해 부동액의 접촉면적을 최대한 증가시킨다. 축열봉의 요철이 나사산형상으로 이루어지거나 돌출부가 나선형으로 형성됨으로써, 부동액이 나사산형상이나 나선형의 돌출부를 따라 나선형의 이동경로를 형성하면서 보다 효율적으로 이동한다.      The unevenness of the heat storage rod, the unevenness of the heat storage donut, and the heat storage ball increase the contact area of the antifreeze as much as possible. As the unevenness of the heat storage rod is threaded or the protrusion is formed spirally, the antifreeze moves more efficiently while forming a spiral moving path along the threaded or spirally projecting portion.

축열봉이 축열도넛에 삽입되어 축열도넛이 정렬되고, 축열봉이 삽입된 축열도넛이 그룹화프레임에 의해 정렬되며, 축열볼 또한 축열도넛 사이에 위치 정렬된다. 이러한 구성에 의해 축열조를 형성하며, 부동액의 주된 흐름에 관계없이 축열조 전체가 일관된 빙축열 기능을 한다.      The heat storage rod is inserted into the heat storage donut to align the heat storage donut, the heat storage donut with the heat storage rod inserted is aligned by the grouping frame, and the heat storage ball is also aligned between the heat storage donuts. This configuration forms a heat storage tank, and the entire heat storage tank functions as a consistent ice storage function regardless of the main flow of the antifreeze.

전술한 도 2 및 도 3의 축열도넛으로 된 축열조를 갖는 본 발명에 따른 빙축열 냉방시스템을 도 4 및 도 5를 참고하여 설명한다.       The ice heat storage cooling system according to the present invention having the heat storage tank made of the heat storage donuts of FIGS. 2 and 3 will be described with reference to FIGS. 4 and 5.

도 4는 본 발명의 일실시예에 따른 빙축열 냉방시스템의 단면도이다.       Figure 4 is a cross-sectional view of the ice heat storage cooling system according to an embodiment of the present invention.

도 4를 참고하면, 빙축열시스템(40)은 하우징내부에 냉동기(41)와 축열조(43) 및 열교환기(49)를 일체로 구성하며, 냉동기(41)와 축열조(43)간에는 저온냉매를 공급하기 위한 냉동밸브(42)를 포함한다. 그리고 열교환기(49)는 축열조(43)와 냉수배관을 통해 연결되어 있으며 냉수배관(47)에는 냉수순환펌프(48)가 형성되어 냉수를 공급한다. 또한, 하우징의 일측에는 공기를 공급하는 공기송풍 구(45)와 열교환기(49)로부터 교환된 냉풍을 배출하기 위한 공기냉풍구(46)를 포함하여 구성한다.       Referring to FIG. 4, the ice heat storage system 40 integrally constitutes a refrigerator 41, a heat storage tank 43, and a heat exchanger 49 in a housing, and supplies a low temperature refrigerant between the freezer 41 and the heat storage tank 43. It includes a refrigeration valve 42 for. The heat exchanger 49 is connected to the heat storage tank 43 through a cold water pipe, and a cold water circulation pump 48 is formed in the cold water pipe 47 to supply cold water. In addition, one side of the housing is configured to include an air cooling port (45) for supplying air and an air cooling hole (46) for discharging the cold air exchanged from the heat exchanger (49).

이렇게 구성된 빙축열시스템(40)은 일체로 형성된 모듈형태로 이동이 자유롭고 소형화가 가능하게 구성한다. 즉, 빙축열시스템(40)은 하우징내부에 냉방에 필요한 냉동기(41)와 축열조(43)와 열교환기(49)를 일체로 구성하여 이격거리를 최소화하도록 구성한다.       The ice storage system 40 configured as described above is freely movable and miniaturized in an integrally formed module form. That is, the ice heat storage system 40 is configured to minimize the separation distance by integrally configuring the refrigerator 41, the heat storage tank 43 and the heat exchanger 49 required for cooling in the housing.

이를 위해 본 발명의 축열조(43)는 다수의 축열도넛(44)을 구비하는 축열구조로 본 발명의 출원인에 의해 기 등록(한국등록특허 10-0692251호)된 것으로, 전술한 도 2 및 도 3을 참고하여 설명한 바 있다.       To this end, the heat storage tank 43 of the present invention has been previously registered by the applicant of the present invention in a heat storage structure having a plurality of heat storage donuts 44 (Korean Patent No. 10-0692251), and the aforementioned FIGS. 2 and 3. It has been described with reference to.

이러한 축열조(43)는 축열도넛(44)의 물이 영하의 얼음으로 빙축하기 위해 냉풍기(41)와 냉동밸브(42)에 의해 연결되어 저온 저압의 냉매를 공급받도록 구성한다. 심야 시간에 전력을 이용해 빙축해야하는 경우 냉풍기(41)에 연결된 냉동밸브(42)를 열어 냉동기(41)의 저온 저압 냉매가 축열조(43)로 공급되어 순환되면, 축열조(43) 내부의 축열도넛(44)의 물이 얼음으로 빙축되면 빙축을 완료한다. 빙축모드에서는 공기송풍구(45)와 공기냉풍구(46)는 밀폐되도록 제어한다.       The heat storage tank 43 is configured to be connected to the cold air blower 41 and the freezing valve 42 so that the water in the heat storage donut 44 is iced with subzero ice so as to receive a low temperature low pressure refrigerant. When it is necessary to freeze ice using electric power at night time, when the low-temperature low-pressure refrigerant of the freezer 41 is supplied to the heat storage tank 43 and circulated by opening the freezing valve 42 connected to the cold air blower 41, the heat storage donut (inside the heat storage tank 43) After the ice of 44) is iced, the ice is completed. In the ice storage mode, the air vents 45 and the air cooling vents 46 are controlled to be sealed.

빙축이 완료된 상태에서, 냉방을 하고자 하는 경우, 열교환기(49)와 축열조(43)간에 순환되는 냉수를 공급하기 위한 냉수순환펌프(48)를 온시킨다. 그리고 열교환기(49)에 의해 차가워진 공기를 공급하기 위한 공기송풍구(45)와 공기냉풍구(46)를 오픈한다. 또한, 열교환기(49)의 일측에는 냉수에 의해 공기를 차갑게 하기 위한 팬을 구성한다. 그러면, 냉수가 축열조(42)를 통과하여 차가워져 계속적 으로 순환하게 되어 열교환기(49)의 내부에 공급되는 공기를 차게 하여 팬에 의해 공기냉풍구(46)를 통해 외부로 배출한다.       When cooling is to be completed while the ice shaft is completed, the cold water circulation pump 48 for supplying cold water circulated between the heat exchanger 49 and the heat storage tank 43 is turned on. Then, the air vent 45 and the air cooling vent 46 for supplying the air cooled by the heat exchanger 49 are opened. In addition, one side of the heat exchanger (49) constitutes a fan for cooling the air by cold water. Then, the cold water cools through the heat storage tank 42 and continuously circulates to cool the air supplied to the inside of the heat exchanger 49, and is discharged to the outside through the air cooling hole 46 by the fan.

도 4의 단면도에서는 도시되지는 않았지만, 전술한 냉방시스템은 내부의 콘트롤러를 포함하여 콘트롤러의 제어에 의해 상기 구성들이 작동됨은 자명하다.       Although not shown in the cross-sectional view of Figure 4, it is apparent that the above-described cooling system includes the controller therein and the above components are operated by the control of the controller.

도 5는 도 4의 빙축열시스템의 제어흐름도이다. 5 is a control flowchart of the ice heat storage system of FIG.

도 5를 참고하면, 빙축열 냉방시스템은 먼저 빙축모드인지를 판단한다(단계 501). 빙축모드라고 판단하면, 냉동밸브를 온하도록 제어한다(단계 502). 냉동밸브가 온되면, 계속적으로 저온냉매가 공급되어 축열조에 얼음이 저장되며, 일정시간동안 수행되어 빙축이 완료되었는지를 판단한다(단계 503) 판단결과 빙축이 완료되었으면, 냉풍밸브를 오프하도록 제어한다(단계 504). 5, the ice storage heat cooling system first determines whether the ice storage mode is in ice storage mode (step 501). If it is determined that the ice storage mode, the refrigeration valve is controlled to turn on (step 502). When the refrigeration valve is turned on, the low-temperature refrigerant is continuously supplied to store ice in the heat storage tank, and it is determined that the ice storage is completed by performing for a predetermined time (step 503). (Step 504).

한편, 빙축모드인지를 판단하여 빙축모드가 아닌 경우, 냉방모드 인지를 판단한다(단계 505). 판단결과, 냉방모드인 경우, 냉수순환펌프를 온하여(단계 506) 열교환기를 통과하는 냉수가 축열조와 교류하도록 한다. 그리고 냉출을 송출하기 위해 송풍구와 냉풍구를 오픈한다(단계 507). 그러면, 냉풍구로 냉수에 의해 차가워진 공기가 배출되어 냉방이 완료된다. On the other hand, it is determined whether the ice is in ice mode, and if not in the ice mode, it is determined whether the cooling mode (step 505). As a result of the determination, in the cooling mode, the cold water circulation pump is turned on (step 506) to allow the cold water passing through the heat exchanger to exchange with the heat storage tank. The tuyere and the cold tuyere are opened to deliver the cold air (step 507). Then, the air cooled by the cold water is discharged to the cold air outlet, and cooling is completed.
