공냉형 흡수식 냉방 시스템에서 LiBr 수용액의 과열도가 증기 흡수에 미치는 영향 = Effect of degree of superheat of LiBr aqueous solution on the vapor absorption process for an air-cooled absorption cooling system

다국어 초록 (Multilingual Abstract)

Numerical analysis using finite volume method has been carried out to examine the effect of degree of superheat of LiBr aqueous solution on heat and mass transfer occurred in absorption process. According to the result of this study, it was found that refrigerant vaper was generated at the entrance region of absorber when LiBr aqueous soltion was superheated. As the degree of superheat increases, heat transfer rate increases and vapor absorption rate decreases. The increase in averaged Nusselt and Sherwood numbers could be found as film Reynolds number increases. The larger the degree of superheat, the greater the averaged Nusselt and Sherwood numbers.
