Description
본 발명은 주거용 아파트, 주상복합건축물, 업무용 빌딩, 호텔, 병원 등과 같은 일반건물에 설치되는 공조시스템에 관한 것으로, 특히 판형 열교환기를 내장한 수냉식 응축기를 이용하여 중앙식 공조방식과 개별식 공조방식의 단점을 보완한 냉각탑 일체형 멀티수냉식 컨덴싱 유닛 공조시스템에 관한 것이다.The present invention relates to an air conditioning system installed in general buildings such as residential apartments, residential complexes, business buildings, hotels, hospitals, etc. In particular, by using a water-cooled condenser with a plate heat exchanger The present invention relates to a cooling tower integrated multi-water cooling condensing unit air conditioning system.
일반적으로, 산업화의 급속한 진전에 따른 도시화의 영향으로 대도시에서는 가용공간을 확보하기 위하여 건물의 고층화와 지하공간의 개발이 활발하게 이루어지고 있다. 최근 증가추세에 있는 초고층 주상복합건물, 초고층아파트는 건물의 높이가 증가함으로써 건축공사비의 증가는 물론, 건물의 초고층화로 인하여 열원에서 공조기까지, 또한 공조기에서 실내기까지의 수직거리가 길어지게 되어 연장된 공조덕트 및 배관의 길이로 인해 반송동력비가 크게 상승하는 문제점을 가지고 있다.In general, due to the effect of urbanization due to the rapid progress of industrialization, in order to secure the available space in the large cities, building upstairs and development of underground spaces are actively performed. As the height of the building increases, the height of the building increases, as well as the construction cost and the vertical distance from the heat source to the air conditioner and the air conditioner to the indoor unit is extended. Due to the air conditioning duct and the length of the pipe has a problem that the transfer power ratio is greatly increased.
특히, 공조시스템은 건물의 LCC(Life Cycle Cost)에서 가장 커다란 비중을 차지하는 에너지 비용과 직접적인 관련이 있기 때문에, 설계 초기단계에서부터 건물의 특성에 적합한 시스템이 선정되도록 신중하게 고려되어야 한다.In particular, the air conditioning system is directly related to the energy cost, which accounts for the largest portion of the building's life cycle cost, so it must be carefully considered to select a system suitable for the building's characteristics from the early stage of design.
상기 공조시스템에는 냉동기, 보일러, 공조기 등이 설치된 중앙 기계실로부터 공조에 필요한 공기를 덕트를 통하여 소요처나 실내에 공급하는 중앙식 공조시스템과, 각 소요처마다 개별적으로 공조기와 실외기를 설치하여 냉난방을 실시하는 개별식 공조시스템이 있다.The air conditioning system provides a central air conditioning system for supplying air required for air conditioning from a central machine room in which a refrigerator, a boiler, an air conditioner, etc. are installed through a duct to a place or a room, and individually installs an air conditioner and an outdoor unit to provide air conditioning and heating. There is a separate air conditioning system.
상기 중앙식 공조시스템은 크게 열원설비, 반송설비 및 제어설비로 구분할 수 있다. 공기조화용으로 소비되는 에너지량은 건물의 용도에 따라 차이가 있지만, 현대식 건물의 경우 건물 전체 에너지소비량의 40 ~ 50% 정도이고, 이 중에서 송풍동력이 차지하는 비율이 약 40% 정도로서 전체 건물 에너지 소비량의 약 16~20%에 이르고 있다. 최근 초고층 건물 등 대규모의 건물이 활발하게 건설되면서 에너지의 반송시스템을 개선하여 유지관리비를 절감하고 공조시스템 설치에 필요한 공간의 축소를 통해 건물의 경제적인 가치를 향상시킬 수 있는 새로운 개념의 공조시스템 개발이 요구되고 있는 실정이다.The central air conditioning system can be largely classified into a heat source facility, a transfer facility, and a control facility. The amount of energy consumed for air conditioning differs depending on the purpose of the building, but in modern buildings, the energy consumption is about 40-50% of the total building energy consumption, and the wind power accounts for about 40% of the total building energy consumption. About 16-20% of the total. With the recent construction of large-scale buildings such as high-rise buildings, the development of a new concept air conditioning system that can improve the economic value of buildings by reducing the maintenance cost and reducing the space required for installing the air conditioning system by improving the energy return system. This situation is required.
종래의 중앙식 공조시스템에서 전공기방식(all air system)이나 공기수방식(air-water system)의 경우, 실내 환기와 외기를 공조기에서 혼합하여 공조구역에 공급하는 방법을 사용하고 있기 때문에, 반송풍량이 증가하여 덕트 공간의 확보로 인한 층고 상승으로 건축비가 상승하는 원인이 되고 있다. 또한, 중앙공조기기의 대형화로 인하여 기계실의 소요면적이 증가되는 문제점을 내포하고 있다. 이 밖에 실제 공조하지 않은 세대 및 상가에 대해서도 반송을 위한 공용기기의 사용으로 인한 기본 부가요금으로 민원이 발생하고 있을 뿐만 아니라, 유지보수를 위한 기간동안은 전세대 및 상가의 냉난방이 불가한 문제점이 있다.In the conventional central air conditioning system, in the case of an all air system or an air-water system, a method of mixing indoor ventilation and outdoor air in an air conditioner and supplying it to an air conditioning area is carried out. As the air volume increases, the building cost rises due to the rise in the floor height due to securing the duct space. In addition, there is a problem that the required area of the machine room increases due to the enlargement of the central air conditioning equipment. In addition, civil complaints are caused by the basic surcharge due to the use of common equipment for returning to households and shopping malls that are not actually coordinated, and there is a problem that heating and cooling of all households and shopping malls are impossible during maintenance period. .
한편, 개별식 공조시스템의 경우는 실외기의 소음 및 진동으로 인한 사용자 및 인근 거주자에게 불쾌한 주거환경을 조성하고, 각각의 공조기기에 대한 실외기 설치면적을 필요로 한다. 최근 적용사례가 증가하고 있는 공냉식 멀티 시스템의 경우, 실외기 설치대수를 줄일수는 있으나, 여전히 필요한 수량의 실외기를 반드시 설치해야만 하며, 이러한 실외기의 설치로 인한 외관상, 미관상의 문제가 발생하고 있다. 또한, 각 개별 소요처마다 설치가 편리한 곳에 실외기가 설치되므로 실외기의 분산설치로 인한 집중관리가 불리한 문제점이 있으며, 냉매의 액화를 위한 응축방식에 있어서, 열수송능력의 차에 의해 수냉식에 비해 실외기 설치면적이 증가하는 문제점을 내포하고 있다.On the other hand, the individual air conditioning system creates an unpleasant living environment for the user and neighboring residents due to the noise and vibration of the outdoor unit, and requires the outdoor unit installation area for each air conditioner. In the case of the air-cooled multi-system which has been increasing in recent years, it is possible to reduce the number of outdoor units installed, but still need to install the required number of outdoor units, and appearance and aesthetic problems are caused by the installation of such outdoor units. In addition, since the outdoor unit is installed in a convenient place for each individual place, there is a disadvantage in that the centralized management due to the distributed installation of the outdoor unit is disadvantageous. The problem is that the installation area increases.
따라서, 본 발명은 상기한 제반 문제점을 해결하기 위하여 안출된 것으로, 개방형 또는 밀폐형 냉각탑에 판형 열교환기가 내장된 수냉식 응축기를 조합하여 각 소요처에 설치함으로써 중앙식 공조방식과 개별식 공조방식의 단점을 보완하고, 에너지를 절약할 수 있는 냉각탑 일체형 멀티수냉식 컨덴싱 유닛 공조시스템을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by installing a combination of a water-cooled condenser with a plate-type heat exchanger in an open or closed cooling tower at each required location to eliminate the disadvantages of the central air conditioning system and individual air conditioning system The purpose of the present invention is to provide a cooling tower integrated multi-water cooling condensing unit air conditioning system that can supplement and save energy.

Recool by heat exchange with. Then, the recooled cooling water is moved through the second cooling water transfer pipe (5), it is supplied to the water-cooled condenser (7) for each floor through a plurality of branch pipes (6). In the water-cooled condenser (7) it is possible to cool the respective requirements by providing the indoor unit by heat-exchanging the cooling water with the refrigerant.
상기와 같이 구성되어 작용하는 본 발명은 최근 건립이 증가하고 있는 초고층주상복합건물 또는 초고층아파트와 같은 건물에 대한 에너지 절약형 표준 공조모델로서 적용이 가능하다.The present invention configured and acting as described above can be applied as an energy-saving standard air-conditioning model for buildings such as high-rise residential complexes or high-rise apartments that have recently been increased in construction.
또한, 본 발명의 실시예에서는 냉방에 필요한 구조에 대한 예시를 보여주고 있으나, 이에 국한하는 것은 아니고, 주상복합건물, 호텔, 콘도 등과 같은 곳에서 겨울철 배수되는 미활용열원을 활용하는 열펌프와 정수처리시설을 채용하여 상가건물의 난방열원으로 사용할 수도 있다. 즉, 주상복합건물에 주로 겸비되어 있는 사우나시설을 통해서 배수되는 배수열이나, 일반 초고층건물에 있어서의 겨울철 각 세대로부터 배수되는 배수열을 열펌프시스템을 채용하여 난방을 행할 수 있다.In addition, the embodiment of the present invention shows an example of the structure required for cooling, but is not limited to this, heat pump and water treatment utilizing an unused heat source that is drained in winter in a residential complex, a hotel, a condo, etc. It is also possible to adopt a facility and use it as a heating source of heating in a mall. In other words, a heat pump system can be used to heat the drainage heat drained through a sauna facility mainly combined with a residential complex, or the drainage heat drained from each generation in winter in a general skyscraper.
이상에서 설명한 본 발명은 전술한 실시예 및 도면에 의해 한정되는 것은 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 고안이 속하는 기술분야에서 통상적인 지식을 가진 자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiments and drawings, and various permutations, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have
전술한 바와 같이 본 발명에 따르면, 물을 대기중의 공기와 열교환하는 냉각탑에 팬의 가동이 필요없는 판형 열교환기가 내장된 수냉식 응축기를 조합함으로써 기존의 공냉식 멀티공조시스템에 비해 열교환능력이 상승하여 실외기의 소요면적을 대폭 감소시킬 수 있다. 또한, 상기 냉각수 배관라인을 동일 수직계통으로 배열함으로써 실외기를 건물의 외부에 분산설치하지 않고, 건물 내부의 다용도실이나 세탁실 등과 같은 작은 바닥면적에 일괄적으로 설치가 가능하기 때문에, 설치에 따른 번거로움을 해소하고, 실외기가 건물 외부에 설치되어 발생하는 미관문제를 완전히 해소할 수 있을 뿐만 아니라, 팬이 내장되어 있는 기존의 공냉식 실외기에서 발생하는 소음과 진동을 차단할 수 있어 민원 발생을 방지할 수 있다.As described above, according to the present invention, by combining a water-cooled condenser with a plate heat exchanger that does not require a fan in a cooling tower that exchanges water with air in the air, the heat exchange capacity is increased compared to a conventional air-cooled multi-air conditioning system. The required area of can be greatly reduced. In addition, by arranging the cooling water piping lines in the same vertical system, it is possible to collectively install the outdoor unit in a small floor area such as a multipurpose room or a laundry room in the building, without having to install the outdoor unit on the outside of the building. It can solve the aesthetic problems caused by the outdoor unit installed outside the building, and can block the noise and vibration generated by the existing air-cooled outdoor unit with a fan, thereby preventing civil complaints. .
또한, 컴팩트한 실내기를 실내 벽면 뿐만 아니라, 천장에 분산설치하는 것이 가능하기 때문에, 기존의 중앙공조방식에서 필요로 하는 덕트의 사용을 배제할 수 있어 건물의 층고를 낮출 수 있다.In addition, since it is possible to distribute the compact indoor unit to the ceiling as well as the indoor wall, it is possible to eliminate the use of the duct required by the existing central air conditioning method can lower the height of the building.
또한, 기존의 공냉식 멀티에어컨과 동일하게 대상공간에 대한 개별적인 제어가 가능할 뿐만 아니라, 각 소요처에 대한 냉방수요에 따라 냉각수량(가동되는 펌프의 대수 또는 펌프의 회전수)을 제어하는 것이 가능함으로써 반송동력을 절감할 수 있는 효과를 가진다.In addition, as in the conventional air-cooled multi-air conditioners, not only individual control of the target space is possible, but also the amount of cooling water (the number of driven pumps or the number of rotations of the pump) can be controlled according to the cooling demand for each required place. It has the effect of reducing the transfer power.
이 밖에, 기존의 개별식 공조시스템에 비해 중앙집중관리가 가능하므로 유지관리 및 보수가 용이하며, 이로 인해 기기의 수명을 연장할 수 있는 부대 효과를 가진다.In addition, the centralized management is possible compared to the existing individual air conditioning system, so it is easy to maintain and repair, which has the side effect of extending the life of the equipment.
