판형열교환기에서 물측 증발 열전달 성능특성에 관한 실험적 연구

The plate heat exchanger(PHE) is developed throughout in 1900s, and widely adopted in many industries up to now. Recently, as the interest about evaporative desalination equipment increases, the study on evaporative PHE is also becoming important. Evaporation heat transfer characteristics in PHE are more complex than those in conventional heat exchangers. In addition, the study on the evaporation heat transfer characteristics of water in PHE is limited in open literature. In this study, the experiment was performed by changing the mass flux, inlet vapor quality, and heat flux to obtain evaporation heat transfer coefficient of water in the PHE, and the basic data ware provided to develop a correlation for performance analysis.
