Description

에너지 절감형 항온항습 공조시스템{Energy-saving Computer Room Air Conditioner}Energy-saving constant temperature and humidity air conditioning system {Energy-saving Computer Room Air Conditioner}

본 발명은 항온항습 공조시스템에 관한 것으로서, 보다 자세히는 “상수, 하수, 중수, 보일러용수, 빌딩냉각수 등 (이하 중간처리수라 한다)”의 계절별 온도차를 이용한 열교환을 통해 항온항습의 운전 에너지를 절감할 수 있는 에너지 절감형 항온항습 공조시스템에 관한 것이다. The present invention relates to a constant-temperature and constant-humidity air conditioning system, and in more detail, reducing the operating energy of constant-temperature and constant-humidity through heat exchange using the seasonal temperature difference of "water, sewage, heavy water, boiler water, building cooling water, etc. (hereinafter referred to as intermediate-treated water)" It relates to an energy-saving constant temperature and humidity air conditioning system.

일반적으로 공기 조화는 실내의 온도, 습도, 세균, 냄새, 기류 등의 조건을 그 장소의 사용 목적에 적합한 상태로 유지하여 주택, 호텔, 회관, 사무실, 전산실 및 각종 산업현장 등에서 생활하는 실내의 사람을 쾌적한 상태로 만드는 것을 목적으로 하는 것으로, 사람에게 쾌적한 공기상태는 기후 조건, 복장, 생활수준, 건강상태 등 여러 가지 조건에 의하여 영향을 받게 되므로 일정한 값이 있는 것은 아니나, 여름에는 온도 26∼28℃, 상대습도 약 50%, 겨울에는 온도 20∼22℃, 상대습도 약 40%를 목표로 하는 것이 보통이다.In general, air conditioning maintains indoor conditions such as temperature, humidity, bacteria, odor, and airflow in a state suitable for the purpose of use of the place. The purpose of making the air comfortable for people is that it does not have a certain value because it is affected by various conditions such as climatic conditions, clothes, living standards, and health conditions, but in summer the temperature is 26~28. ℃, relative humidity of about 50%, in winter, it is normal to aim for a temperature of 20-22℃ and a relative humidity of about 40%.

그러나 이와 같은 값은 절대적인 것은 아니며, 공장의 작업장, 창고, 실험실, 전산실 등의 장소가 그 기능을 충분히 달성하기 위해서는 거기서 생산되고 가공되며 저장 또는 시험되는 물건이나 해당 장소에서 운영 중인 각종 기기에 가장 알맞은 상태를 유지하도록 하여야 한다.However, these values are not absolute, and in order for places such as workshops, warehouses, laboratories, and computer rooms of factories to fully achieve their functions, the most suitable state should be maintained.

특히, 일정한 온습도를 요구하는 제품 처리과정이라든지, 전산실, 정밀 측정실, 엔진실험실, 반도체 공장의 클린룸 등은 일정한 설정온도(일례로, 22℃), 설정습도(일례로 50%)를 유지하기 위해 항온항습기가 사용되고 있다.In particular, in product processing processes that require constant temperature and humidity, computer rooms, precision measurement rooms, engine laboratories, and clean rooms of semiconductor factories, in order to maintain a constant set temperature (for example, 22℃) and set humidity (for example, 50%), A thermo-hygrostat is used.

도 1은 종래 항온항습기의 구조도를 도시하고 있다. 종래 항온항습기는 송풍기(10), 냉각기(20), 가습기(30), 히터(40)를 포함하는 것으로 구성된다. 한편, 냉각기(20)는 압축기(21), 응축기(22), 팽창변(23), 증발기(24)로 이루어지는 냉각 사이클을 형성하며, 히터(40)는 냉각 제습 운전의 수행 중 증발기(24)를 통해 과냉각된 공기를 요구되는 온도로 재가열하도록 증발기(24)의 후단에 배치된다.1 shows a structural diagram of a conventional thermo-hygrostat. A conventional thermo-hygrostat is configured to include a blower 10 , a cooler 20 , a humidifier 30 , and a heater 40 . On the other hand, the cooler 20 forms a cooling cycle consisting of the compressor 21, the condenser 22, the expansion valve 23, and the evaporator 24, and the heater 40 operates the evaporator 24 during the cooling and dehumidification operation. It is disposed at the rear end of the evaporator 24 to reheat the supercooled air to the required temperature through the evaporator.

이와 같은 종래의 항온항습기는 냉각운전과정에서 압축기(21)를 계속 구동하게 되므로 에너지 사용량이 많은 단점이 있으며, 히터(40)의 사용에 의한 전력사용이 증가하여 관리비용이 증가하는 단점이 있다. Such a conventional thermo-hygrostat continuously drives the compressor 21 during the cooling operation, so it consumes a lot of energy, and there is a disadvantage in that the use of the heater 40 increases power consumption, thereby increasing the management cost.

본 발명의 목적은 상술한 문제를 해결하기 위한 것으로, 계절에 따라 온도가 변화되는 중간처리수와 열교환기를 통해 항온항습기 운전을 위한 냉각수를 열교환함으로써 프리쿨링과 냉각사이클에 의한 쿨링, 프리쿨링과 냉각사이클을 함께 이용하는 하이브리드 쿨링 중 어느 하나로 공간의 온도에 따라 선택적으로 구동하여 항온항습 유지에 요구되는 전력사용량을 최소화할 수 있는 에너지절감형 항온항습 공조시스템을 제공하는 것이다. An object of the present invention is to solve the above-mentioned problem, by exchanging heat with intermediate-treated water whose temperature is changed according to the season and cooling water for constant temperature and humidity operation through a heat exchanger, cooling by pre-cooling and cooling cycle, pre-cooling and cooling It is to provide an energy-saving constant temperature and humidity air conditioning system that can minimize the power consumption required to maintain constant temperature and humidity by selectively driving according to the temperature of the space as any one of hybrid cooling that uses a cycle together.

또한, 본 발명의 다른 목적은, 종래 “수냉식 항온항습기 또는 수냉식 프리쿨링 항온항습기”에 반영되는 실외기인 냉각탑을 사용하지 않고 판형 열교환기를 설치하여 냉각탑 역할을 대체함으로써 항온항습시설 구축에 필요한 건설비용 저감 가능하며, 기존 냉각탑 설치 시 냉각탑 운영에 필요한 전력과 용수사용량을 대체함으로써 에너지절감과 용수 절감의 효과를 얻을 수 있는 시스템을 제공하는 것이다.In addition, another object of the present invention is to replace the role of a cooling tower by installing a plate heat exchanger without using a cooling tower, which is an outdoor unit, which is reflected in the conventional “water-cooled thermo-hygrostat or water-cooled pre-cooling thermo-hygrostat”, thereby reducing the construction cost required for building a constant temperature and humidity facility It is possible to provide a system that can achieve the effect of saving energy and water by replacing the power and water consumption required for cooling tower operation when installing the existing cooling tower.

또한, 본 발명의 또 다른 목적은, 중간처리수로 하수처리장 원수를 이용할 경우 열교환을 통해 하수의 온도가 상승시킴으로써 하수처리 과정에서 미생물 증식에 필요한 열을 부대적으로 얻을 수 있으므로 궁극적으로 하수처리장 에너지 절감을 유도할 수 있다. 또한 보일러 용수 등을 활용한 열교환 시에는 보일러 가동 시의 연료비용 절감을 유도할 수 있다. In addition, another object of the present invention is that when raw water from a sewage treatment plant is used as an intermediate treatment water, the temperature of the sewage is increased through heat exchange, so that heat necessary for the growth of microorganisms in the sewage treatment process can be obtained incidentally, so ultimately the energy of the sewage treatment plant can lead to savings. In addition, heat exchange using boiler water, etc. can induce fuel cost reduction during boiler operation.

도 6의 (a)와 (b)에 도시된 바와 같이 열교환기(400)는 내부냉각수이동관(410)과 외부처리수이동관(420)이 서로 중첩되게 배치되어 열교환이 이루어진다. 내부냉각수이동관(410)의 양단(411,413)은 각각 냉각수유입관(210) 및 냉각수배출관(245)이 연결되고, 외부처리수이동관(420)은 양단(421,423)이 각각 중간처리수유입관(310)과 중간처리수배출관(320)이 연결된다.

도 6의 (a)에 확대도시된 바와 같이 중간처리수(M1)가 내부냉각수이동관(410)의 외부를 감싸 중간처리수(M1)와 냉각수(W1)의 열교환이 이루어진다. 6A , the intermediate treated water M1 surrounds the outside of the internal coolant pipe 410 to exchange heat between the intermediate treated water M1 and the cooling water W1.

제어부(500)는 중간처리수온도센서(311)에서 감지된 중간처리수(M1)의 현재온도와 냉각수온도센서(211)에서 감지된 냉각수(W1)의 현재온도를 기준으로 냉각수(W1)의 이동경로를 조절하고, 냉각사이클부(100)이 동작여부를 제어한다. The control unit 500 controls the temperature of the cooling water W1 based on the current temperature of the intermediate treatment water M1 detected by the intermediate treatment water temperature sensor 311 and the current temperature of the cooling water W1 detected by the cooling water temperature sensor 211 . It adjusts the movement path and controls whether the cooling cycle unit 100 operates.

제어부(500)는 중간처리수(M1)의 온도가 낮은 동절기에는 도 2에 도시된 바와 같이 냉각사이클부(100)를 동작하지 않고 실내공기(A)를 냉각수(W1)와의 열교환만으로 냉각하는 프리쿨링이 수행되게 한다. In the winter season when the temperature of the intermediate treated water M1 is low, the control unit 500 does not operate the cooling cycle unit 100 as shown in FIG. 2 and cools the indoor air A only through heat exchange with the cooling water W1. Let cooling be performed.

또한, 제어부(500)는 중간처리수(M1)의 온도가 높은 하절기에는 도 4에 도시된 바와 같이 냉각사이클부(100)만 사용하여 실내공기(A)를 냉각하는 냉각사이클 쿨링이 수행되게 한다. In addition, the control unit 500 performs cooling cycle cooling for cooling the indoor air A using only the cooling cycle unit 100 as shown in FIG. 4 in the summer season when the temperature of the intermediate treated water M1 is high. .

중간처리수(M1)의 온도가 냉각수(W1)만으로 실내공기(A)를 냉각하기에 부족한 간절기일 때는 냉각수(W1)를 이용한 실내공기(A) 냉각과, 냉각사이클을 이용한 냉각을 동시에 이용하는 하이브리드 쿨링이 수행되게 한다.

도 2에 도시된 바와 같이 동절기에는 중간처리수(M1)의 온도가 낮으므로 냉각수(W1)는 열교환기(400)에서 열교환 후 온도가 충분히 낮아진다. 이에 냉각수(W1)는 냉각수유입관(210)을 통해 냉각수유동코일(230)로 이동되고, 냉각수유동코일(230)에서 실내공기(A)와 열교환된다. As shown in FIG. 2 , since the temperature of the intermediate treated water M1 is low in winter, the temperature of the cooling water W1 is sufficiently lowered after heat exchange in the heat exchanger 400 . Accordingly, the cooling water W1 moves to the cooling water flow coil 230 through the cooling water inlet pipe 210 and exchanges heat with the indoor air A in the cooling water flow coil 230 .

냉각수유동코일(230)에서 실내공기(A)와 열교환하며 온도가 상승된 열교환 냉각수(W2)는 냉각수유출관(240)을 따라 이동되고, 제1삼방밸브(250)는 냉각수배출관(245)으로 열교환 냉각수(W2)가 배출되게 제어부(500)에 의해 개폐조작된다. In the cooling water flow coil 230, the heat exchange cooling water W2, whose temperature is increased by exchanging heat with the indoor air A, is moved along the cooling water outlet pipe 240, and the first three-way valve 250 is connected to the cooling water outlet pipe 245. The opening and closing operation is performed by the control unit 500 so that the heat exchange cooling water W2 is discharged.

이에 의해 열교환 냉각수(W2)는 냉각수배출관(245)을 통해 열교환기(400)의 내부냉각수이동관(410)으로 이동되고, 중간처리수(M1)와 열교환 후 다시 냉각수유입관(210)으로 이동되며 순환경로로 순환되고 프리쿨링이 수행된다. As a result, the heat exchange cooling water W2 is moved to the internal cooling water transfer pipe 410 of the heat exchanger 400 through the cooling water discharge pipe 245, and after heat exchange with the intermediate treated water M1, it is moved to the cooling water inlet pipe 210 again. It is circulated in a circulation path and pre-cooling is performed.

한편, 도 3에 도시된 바와 같이 간절기의 경우 중간처리수(M1)의 온도가 냉각수(W1)를 냉각하기에 충분하지 않다. 이에 따라 냉각수유입관(210)을 통해 냉각수유동코일(230)로 냉각수(W1)가 이동되고 실내공기(A)와 열교환된다. On the other hand, as shown in FIG. 3 , in the case of the changing season, the temperature of the intermediate treated water M1 is not sufficient to cool the cooling water W1. Accordingly, the cooling water W1 is moved to the cooling water flow coil 230 through the cooling water inlet pipe 210 and exchanged heat with the indoor air A.

1차공조공기(A1)는 냉각수유동코일(230)에서 열교환된 후 항온항습에서 요구되는 제2온도(T2) 보다 높은 제3온도(T3>T2)로 냉각된다. The primary air conditioning air (A1) is cooled to a third temperature (T3>T2) higher than the second temperature (T2) required for constant temperature and humidity after heat exchange in the cooling water flow coil (230).

제어부(500)는 1차공조공기(A1)의 추가 냉각을 위해 냉각사이클부(100)를 구동한다. 압축기(110)가 동작되며 냉매가 순환되고, 증발기(130)에서 1차공조공기(A1)가 열교환되며 제2온도(T2)를 갖는 2차공조공기(A2)로 냉각된다. 2차공조공기(A2)는 송풍팬(140)을 통해 실내로 배출된다. The control unit 500 drives the cooling cycle unit 100 for additional cooling of the primary air conditioning air A1. The compressor 110 is operated, the refrigerant is circulated, and the primary air conditioning air A1 is heat exchanged in the evaporator 130 and cooled by the secondary air conditioning air A2 having a second temperature T2. The secondary air conditioning air (A2) is discharged into the room through the blowing fan (140).

냉각수유출관(240)으로 배출된 열교환 냉각수(W2)는 냉각수배출관(245)을 따라 이동되고, 제2삼방밸브(260)의 경로전환에 의해 응축기유입관(270)으로 유입된다. 열교환 냉각수(W2)는 응축기탱크(123)로 유입된 후 응축기냉매이동관(121)과 열교환되며 온도가 상승된다.The heat exchange cooling water W2 discharged to the cooling water outlet pipe 240 is moved along the cooling water discharge pipe 245 , and is introduced into the condenser inlet pipe 270 by path switching of the second three-way valve 260 . The heat exchange cooling water W2 flows into the condenser tank 123 and heat exchanges with the condenser refrigerant pipe 121 to increase the temperature.

응축기(120)에서 열교환되며 온도가 상승된 열교환 냉각수(W2)는 냉각수배출관(245)을 통해 열교환기(400)의 내부냉각수이동관(410)으로 공급되고 중간처리수(M1)와 열교환 후 동일한 하이브리드 쿨링 경로를 따라 순환된다. The heat exchange coolant W2, which is heat exchanged in the condenser 120 and whose temperature is increased, is supplied to the internal coolant transfer pipe 410 of the heat exchanger 400 through the coolant discharge pipe 245, and after heat exchange with the intermediate treated water M1, the same hybrid It circulates along the cooling path.

한편, 중간처리수(M1)의 온도가 냉각수(W1)의 온도가 차이가 없거나 더 높은 하절기의 경우 도 4에 도시된 바와 같이 열교환기(400)에서 열교환된 냉각수(W1)는 냉각수유입관(210)으로 이동되고, 제1삼방밸브(250)의 경로조절에 의해 냉각수유동코일(230)로 유입되지 못하고 유동코일 바이패스관(215)을 통해 냉각수배출관(245)으로 배출된다. 그리고 다시 열교환기(400)로 유입된다. On the other hand, in the case of the summer season when the temperature of the intermediate treated water M1 has no difference or is higher than the temperature of the cooling water W1, the cooling water W1 heat-exchanged in the heat exchanger 400 as shown in FIG. 210), and is not introduced into the cooling water flow coil 230 by the path control of the first three-way valve 250 and is discharged to the cooling water discharge pipe 245 through the flow coil bypass pipe 215. And it flows into the heat exchanger 400 again.

이 때, 냉각사이클부(100)는 냉매를 순환하고, 실내공기(A)는 증발기(130)에서 열교환을 통해 희망하는 항온온도(T2)로 냉각되어 배출된다. At this time, the cooling cycle unit 100 circulates the refrigerant, and the indoor air A is cooled to a desired constant temperature T2 through heat exchange in the evaporator 130 and discharged.

이상에서 살펴본 바와 같이 본 발명에 따른 항온항습 공조시스템은 동절기에는 중간처리수와 냉각수를 냉각한 후 냉각수유동코일에서 실내공기와 열교환하여 프리쿨링방식으로 동작할 수 있다. As described above, the constant temperature and humidity air conditioning system according to the present invention can be operated in a pre-cooling manner by cooling the intermediate treated water and cooling water in the winter season and then exchanging heat with the indoor air in the cooling water flow coil.

또한, 본 발명의 항온항습 공조시스템은 간절기에는 냉각수를 이용한 열교환과 냉매사이클에 의한 열교환을 동시에 이용하여 실내공기를 냉각할 수 있다. In addition, the constant temperature and humidity air conditioning system of the present invention can cool indoor air by simultaneously using heat exchange using cooling water and heat exchange by a refrigerant cycle in the changing season.

또한, 하절기에는 냉각수는 사용하지 않고 냉매사이클만 사용하여 실내공기를 냉각할 수 있다. In addition, in summer, the indoor air can be cooled by using only the refrigerant cycle without using the cooling water.

이에 의해 본 발명의 항온항습 공조시스템은 공간의 항온항습에 요구되는 전기에너지를 절감할 수 있다. Accordingly, the constant temperature and humidity air conditioning system of the present invention can reduce the electrical energy required for the constant temperature and humidity of the space.

또한, 종래 프리쿨링 수냉식 공조 방식 대비 낮은 PUE(전력효율지수)을 달성할 수 있다. In addition, it is possible to achieve a lower PUE (Power Efficiency Index) compared to the conventional pre-cooling water-cooled air conditioning method.

또한, 종래 프리쿨링 수냉식 공조방식에 적용되는 실외기를 사용하지 않고 열교환기로 대체함으로써 최근 부각되는 WUE(Water Usage Efficiency) 관점에서 별도의 물 사용량이 없는 장점이 있다. In addition, there is an advantage in that there is no separate water consumption in terms of WUE (Water Usage Efficiency), which has recently been highlighted by replacing the outdoor unit with a heat exchanger instead of using the outdoor unit applied to the conventional precooling water cooling air conditioning system.

또한, 구성 단순화로 유지관리가 용이하고 규모 확장이 용이한 장점이 있다. In addition, there are advantages of easy maintenance and easy scale expansion due to simplified configuration.

또한, 중간처리수로 하수처리장의 하수를 사용할 경우 미생물 증식에 필요한 열을 추가 동력 없이 열교환기에서의 열교환에 의해 얻을 수 있는 장점이 있다. In addition, when using sewage from a sewage treatment plant as an intermediate treatment, there is an advantage in that heat required for microbial growth can be obtained by heat exchange in a heat exchanger without additional power.
