초록

최적의 환기시스템 활용과 에너지 절약을 위한 급 배기공기 간의 열교환을 적용시킨 열회수시스템의 활용과 보급은 에너지관리시스템에서 필수적이다. 이러한 기술은 특히, 겨울철과 여름철의 냉난방에너지를 절약할 수 있어 고효율에너지 빌딩의 기반기술의 주요 요소이다. 본 논문에서는 균일한 형상과 동일한 유동조건에서 열교환기 성능을 비교하기 위해 종이, 플라스틱, 알루미늄을 재질로 시뮬레이션을 통한 열전달효율을 검토하였다. 또한 평판형과 굴절형 구조를 갖는 열교환기의 형상에 따른 열전달 효율을 시험하였고, 그 결과를 토대로 열전달 성능과 압력손실에 대해 고성능의 열교환기를 제작하는데 기여를 할 수 있을 것으로 기대된다.

Application of heat recovery system applying air supply and cexhaust ventilation device essential in energy management system for the optimum ventilation system utilization and energy saving. This is a key element of infrastructure technology for high-efficiency energy buildings, because it can save heating and cooling energy in winter and summer. In this paper, heat transfer efficiency was simulated using paper, plastic, and aluminum materials that was examined to compare heat exchanger performance under uniform flow conditions. We tested heat transfer efficiengy according to the shape of two of that, one is orthogonal and the other is refraction shape. Based on the simulation results, it is expected to contribute to the production of high performance heat exchanger with heat transfer performance and pressure loss.
