Description

선박의 엔진 폐열을 이용한 흡착식 냉방시스템{Adsorption cooling system using marine engine waste heat}Adsorption cooling system using marine engine waste heat
본 발명은 선박의 엔진 폐열을 이용한 흡착식 냉방시스템에 관한 것으로서, 보다 구체적으로는 선박의 엔진과 발전기 등에서 폐열을 회수하여 냉방을 제공하므로 친환경적이고 에너지효율적인 것은 물론 냉방 부하량 변동에 무관하게 연속적이고 안정적인 작동이 가능한 선박의 엔진 폐열을 이용한 흡착식 냉방시스템에 관한 것이다.The present invention relates to an adsorption-type cooling system using waste heat of the engine of a ship, and more specifically, to provide cooling by recovering waste heat from an engine and a generator of the ship, which is environmentally friendly and energy efficient, as well as continuous and stable operation regardless of cooling load variation. This relates to an adsorptive cooling system utilizing the engine waste heat of a ship.
상선, 해양, 특수선 등 대부분의 선박에 공기조화 및 냉동을 위하여 설치되는 칠링플랜트(Chilling Plant)는 기계식 냉방시스템으로서 압축기를 이용하여 증발기에서 증발된 냉매를 고온 고압으로 압축하여 응축기에서 응축시킨 후 팽창밸브를 거쳐 냉방에 이용하는 구조상 전력 부하를 요하여 에너지 효율이 높지 않으며 진동과 소음의 발생을 수반한다. Chilling Plant, which is installed for air conditioning and refrigeration on most vessels such as commercial vessels, oceans, and special vessels, is a mechanical cooling system that uses a compressor to compress the refrigerant evaporated from the evaporator at high temperature and high pressure to condense it in the condenser and expand it. It requires a power load due to the structure used for cooling through the valve, so it is not energy efficient and involves vibration and noise.
최근 친환경, 저소음/저진동, 에너지의 효율적인 이용 등에 대한 관심이 높아 기계식보다 흡수식/흡착식 냉방시스템의 선호도가 높아지면서 실제 육상에서는 그 적용 사례가 증가되고 있는 추세이다. 특히 선박에서는 엔진 및 발전기의 고온의 폐열을 가까운 곳에서 바로 얻을 수 있으므로 흡착식 냉방 시스템의 적용가능성이 높을 것으로 전망된다. Recently, as interest in eco-friendly, low noise / low vibration, and efficient use of energy is high, the preference of absorption / adsorption cooling system is higher than that of mechanical type, and the application cases are increasing in actual land. Especially in ships, high-temperature waste heat from engines and generators can be directly obtained from nearby places, so the applicability of adsorption cooling system is expected to be high.
선행특허의 일예로서, 한국 등록특허공보 제1096056호는 엔진 폐열을 열원으로 사용하고, 가열로 상기 냉매와 상기 흡수제를 분리시켜 추출하는 재생기; 상기 분리된 기상의 상기 냉매를 냉각수를 이용하여 응축시키는 응축기; 상기 응축된 액상의 상기 냉매를 저압에서 증발시키는 증발기; 상기 증발기에서 증발된 냉매를 흡수제로 흡수하여 상기 혼합물을 생성시키되, 냉각수를 이용하여 냉각하는 흡수기;를 포함하는 구성을 제안한다. As an example of the prior patent, Korean Patent No. 1096056 discloses a regenerator using engine waste heat as a heat source and separating and extracting the refrigerant and the absorbent by heating; A condenser to condense the separated gaseous refrigerant using cooling water; An evaporator for evaporating the refrigerant of the condensed liquid phase at low pressure; The absorber which absorbs the refrigerant evaporated in the evaporator as an absorbent to generate the mixture, and cools using a coolant;
전자는 친환경성과 경세성에 더하여 상대적으로 비용이 저렴한 상온 압축기를 활용할 수 있는 장점을 기대하지만 다수의 열교환기를 사용하여 설치공간을 넓게 차지하고 근본적으로 압축기에 의존하므로 에너지 효율성의 한계가 있다.The former expects the advantage of utilizing a relatively inexpensive room temperature compressor in addition to eco-friendliness and lightness, but uses a large number of heat exchangers to occupy a large amount of installation space and fundamentally depends on the compressor, thereby limiting energy efficiency.
선행특허의 다른 예로서, 한국 등록특허공보 제1095601호는 선박 엔진의 폐열을 이용한 냉동시스템으로서: 선박 엔진 냉각수의 열을 이용하여 흡수제에 냉매가 흡수된 희용액을 가열하여 냉매를 분리하는 발생기; 상기 발생기로부터 전달되는 증기상태의 냉매를 액체상태로 응축하는 응축기; 상기 냉매의 증발을 통한 냉수와의 열교환을 발생시키는 증발기; 상기 증발기의 냉매를 전달받아 흡수제에 흡수시켜서 희용액을 생성하여 상기 발생기로 제공하는 흡수기; 및 상기 흡수제와 함께 수용된 다수개의 교반보조요소를 포함하는 구성을 제안한다.As another example of the prior patent, Korean Patent No. 1095601 discloses a refrigeration system using waste heat of a ship engine, comprising: a generator for separating a refrigerant by heating a rare solution in which a refrigerant is absorbed into an absorbent by using heat of the ship engine coolant; A condenser for condensing the vapor refrigerant delivered from the generator into a liquid state; An evaporator for generating heat exchange with cold water through evaporation of the refrigerant; An absorber that receives the refrigerant of the evaporator and absorbs the absorbent into the absorbent to generate a rare solution to the generator; And a plurality of stirring aids housed together with the absorbent.
이는 전체적으로 작은 사이즈로 구현될 수 있으면서 전체 시스템의 신속하고 신뢰성있는 동작을 도모하지만, 다양한 선박에서 지속적이고 효율적으로 냉방부하를 감당하는 작동의 신뢰성을 확보하기 미흡하다.While this can be implemented in a small size as a whole, it promotes rapid and reliable operation of the entire system, but it is insufficient to ensure the reliability of the operation to sustain the cooling load continuously and efficiently in various vessels.

이하, 첨부된 도면에 의거하여 본 발명의 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 엔진의 냉각수를 고온수관(11)과 저온수관(12)으로 유도하여 흡착식으로 냉방하는 시스템에 관련된다. 흡착식 냉방시스템의 일예에 있어서 흡착제로 활성탄, 실리카겔, 제올라이트 중 하나를 사용하고 냉매로 물, 수소불화탄소(HFC), 메탄올, 암모니아 중의 하나를 사용할 수 있다. 고온수관(11)은 엔진 또는 발전기의 폐열을 회수하는 관로로서, 고온의 폐열 냉각수(고온수)를 회수하여 흡착제/냉매의 탈착을 위한 열원으로 사용한다. 저온수관(12)은 엔진의 냉각 청수(fresh water)(저온수)를 공급받는 관로로서, 흡착제/냉매의 흡착을 위한 냉각수로 사용한다. 저온수관(12)은 경우에 따라서 해수를 공급받도록 구성할 수도 있다.The present invention relates to a system for guiding the cooling water of an engine to a high temperature water pipe (11) and a low temperature water pipe (12) for cooling by adsorption. In one example of an adsorption cooling system, one of activated carbon, silica gel, and zeolite may be used as an adsorbent, and one of water, hydrofluorocarbon (HFC), methanol, and ammonia may be used as a refrigerant. The high temperature water pipe 11 is a pipe for recovering waste heat of an engine or a generator, and recovers high temperature waste heat cooling water (hot water) and uses it as a heat source for desorption of an adsorbent / refrigerant. The low temperature water pipe 12 is a pipe for receiving cooling fresh water (low temperature water) of the engine and is used as cooling water for adsorption of an adsorbent / refrigerant. The cold water pipe 12 may be configured to receive seawater in some cases.
본 발명에 따르면 반응수단이 흡착과 탈착을 교번하도록 제1반응기(21)와 제2반응기(22)를 구비하는 구조이다. 반응수단은 흡착반응과 탈착반응을 독립적으로 수행하는 2개의 흡착기로서 동일한 규격의 제1반응기(21)와 제2반응기(22)를 병렬로 배치한다. 고온수관(11)에 공급되는 선박 엔진/발전기의 냉각수(Jacket Water)는 출구 온도가 90℃ 정도로 흡착반응을 유발하기에 충분한 온도이다.According to the present invention, the reaction means is provided with a first reactor 21 and a second reactor 22 to alternate adsorption and desorption. The reaction means are two adsorbers which independently perform the adsorption reaction and the desorption reaction, and arrange the first reactor 21 and the second reactor 22 of the same standard in parallel. Cooling water (Jacket Water) of the ship engine / generator supplied to the hot water pipe (11) is a temperature sufficient to cause an adsorption reaction at an outlet temperature of about 90 ℃.
이때, 상기 제1반응기(21)와 제2반응기(22)는 고온수관(11)에 고온밸브(33)를 개재하여 연결되는 동시에 저온수관(12)에 저온밸브(43)를 개재하여 연결된다. 고온수관(11)은 고온밸브(33)를 통하여 제1반응기(21)와 제2반응기(22)에 병렬로 분기되고, 저온수관(12)은 저온밸브(43)를 통하여 제1반응기(21)와 제2반응기(22)에 병렬로 분기된다.At this time, the first reactor 21 and the second reactor 22 are connected to the high temperature water pipe 11 through the high temperature valve 33 and at the same time, the low temperature water pipe 12 to the low temperature valve 43. . The high temperature water pipe 11 is branched in parallel to the first reactor 21 and the second reactor 22 through the high temperature valve 33, and the low temperature water pipe 12 is connected to the first reactor 21 through the low temperature valve 43. ) And the second reactor 22 in parallel.
이때, 상기 고온밸브(33)와 저온밸브(43)는 3방향밸브를 사용하는 것을 특징으로 한다. 3방향밸브인 고온밸브(33)는 고온수관(11)의 고온수를 제1반응기(21) 또는 제2반응기(22)로 선택적으로 공급하고, 3방향밸브인 저온밸브(43)는 저온수관(12)의 저온수를 제1반응기(21) 또는 제2반응기(22)로 선택적으로 공급한다. 이에 따라, 어느 일측의 반응기(21)(22)가 열을 제공받아 탈착반응을 수행하는 동안 타측의 반응기(21)(22)는 반대로 열을 방출하여 흡착반응을 수행한다.At this time, the high temperature valve 33 and the low temperature valve 43 is characterized by using a three-way valve. The high temperature valve 33, which is a three-way valve, selectively supplies the high temperature water of the high temperature water pipe 11 to the first reactor 21 or the second reactor 22, and the low temperature valve 43, which is a three-way valve, is a low temperature water pipe. The low temperature water of (12) is selectively supplied to the first reactor 21 or the second reactor 22. Accordingly, while one of the reactors 21 and 22 receives heat and performs the desorption reaction, the other reactors 21 and 22 release heat to perform the adsorption reaction.
한편, 상기 제1반응기(21)와 제2반응기(22)는 엔진의 정지시, 고온수의 온도가 탈착에 필요한 온도가 되지 않을 경우 열원을 제공받도록 보조히터(28)를 더 구비하는 것이 바람직하다. 보조히터(28)는 만약 엔진/발전기의 폐열을 이용할 수 없을 때 냉방이 필요한 경우에 사용할 수 있도록 제1반응기(21)와 제2반응기(22)에 각각 구비된다. 보조히터(28)의 열원은 전기력 외에 태양열 등의 다른 열원도 사용할 수 있다. 태양열을 이용할 경우에는 엔진/발전기가 완전 고장시에도 선박을 냉방할 수 있어 특히 여객선이나 상선 등에서 선박 사고시에 유용하게 대처할 수 있다.Meanwhile, the first reactor 21 and the second reactor 22 may further include an auxiliary heater 28 to receive a heat source when the temperature of the hot water does not become a temperature required for desorption when the engine is stopped. Do. The auxiliary heater 28 is provided in the first reactor 21 and the second reactor 22, respectively, to be used when cooling is required when waste heat of the engine / generator is not available. The heat source of the auxiliary heater 28 may use other heat sources such as solar heat in addition to the electric force. If solar power is used, the engine / generator can cool the vessel even when the engine is completely out of order, which makes it particularly useful in case of a ship accident, such as a passenger ship or a commercial ship.
또, 본 발명에 따르면 응축기(24)가 상기 제1반응기(21)와 제2반응기(22) 중 하나에서 공급된 냉매를 액상화한다. 응축기(24)는 반응기(21)(22) 중 탈착반응을 거쳐 발생한 냉매증기를 응축하도록 배관 연결된다. 응축기(24)의 냉각을 위하여 연결되는 저온수관(12)은 전술한 반응기(21)(22)의 저온수관(12)과 동일한 라인으로 연결할 수 있다.According to the present invention, the condenser 24 liquefies the refrigerant supplied from one of the first reactor 21 and the second reactor 22. The condenser 24 is piped to condense the refrigerant vapor generated through the desorption reaction in the reactors 21 and 22.
