본 고안은, 다층 공동주택의 주방 환기설비용 이중관덕트를 연결할 수 있는 이중관덕트의 연결구조에 관한 것이다.The present invention relates to a connection structure of a double pipe duct that can connect a double pipe duct for kitchen ventilation equipment of a multi-storey multi-family house.

최근에 일부 고급 아파트의 경우, 특히 주방환기를 위해 급기설비가 설치되고는 있지만, 이러한 급기설비는 배기설비와 이격되게 설치되거나, 급기설비의 주덕트와 배기설비의 주덕트를 동일한 환기덕트샤프트(피트)내에 설치하고, 통상 옥상에 배기팬과 급기팬을 설치하여 공기를 공급하고 실내 공기를 배출시키도록 구성되어 있다.Recently, some high-end apartments have been provided with air supply, especially for kitchen ventilation, but these air supply units are installed separately from the exhaust system, or the main duct of the air supply system and the main duct of the exhaust system have the same ventilation duct shaft ( Pit), and an exhaust fan and an air supply fan are normally provided on the roof to supply air and exhaust the indoor air.

그러나, 이 방식은 급기 닥트를 위한 건축 면적의 확보, 세대별 급기 풍량의 불균형, 추운 겨울철에 급기로 인한 냉기(Cold Draft)현상 등의 문제점을 가지고 있다. 또한, 아파트의 실내 환기 설비를 연계하여 주방의 필요 급기를 마련하는 방 안도 있으나 이는 실내공간들내에서의 기류 유동의 신뢰성 문제와 시스템의 복잡성 등으로 인한 유지 관리에 문제점이 있으며, 이 방법은 아파트 실내 전체에 환기 설비를 구비할 경우에만 가능하고, 환기 설비만 세대당 250∼400 만원의 초기 설비투자비가 선행되어야 하므로 보편화되기에는 어려움이 있다.However, this method has problems such as securing a building area for air supply ducts, unbalance of air supply air volume by generation, and cold drafts due to air supply during cold winter seasons. In addition, there is a way to provide the necessary air supply of the kitchen by connecting the indoor ventilation equipment of the apartment, but there is a problem in the maintenance due to the reliability of the air flow in the indoor spaces and the complexity of the system, this method is an apartment It is possible only if the entire ventilation equipment is provided, and the ventilation equipment is difficult to be universalized since the initial equipment investment cost of 250 to 400 million won per household must be preceded.

상기의 문제점들을 해결하기 위한 것으로서, 주방급기로 인한 겨울철의 콜드 드래프트(Cold draft; 냉기)현상을 감소시킬 수 있으며, 또한 폐열을 회수하여 실내로 전달함으로서 에너지 절감 효과가 있을 뿐만 아니라, 급기효율과 배기효율을 향상시킬 수 있으며, 별도의 급기 닥트를 설치할 필요가 없어 사용공간을 훨씬 적게 차지하고 상대적으로 시공비도 휠씬 적게 드는 구조의 다층 공동주택의 주방 환기설비에 대하여 본 출원인의 명의로 실용신안등록 제20-372149호로 등록 및 기술평가유지결정받았으며, 대표적인 실시예가 도 1로 도시된다.In order to solve the above problems, it is possible to reduce the cold draft (cold air) phenomenon in the winter due to the kitchen air supply, and also to save energy by delivering waste heat to the room, energy efficiency and It is possible to improve the exhaust efficiency and do not need to install a separate air supply duct, which occupies much less space and has a relatively lower construction cost. 20-372149 has been registered and technical evaluation maintenance decision, a representative embodiment is shown in FIG.
