摘要: ABSTRACT:A simulation program was developed to evaluate the heat transfer performance of a multi-pass fin-tube evaporator, considering pressure drop in distributor and capillary tubes. The effect tube length for each pass analyzed with various inlet air flow types distributions. appropriate distribution correlation were deter-mined correlated results agreed well simulation, an average error less than 7%. By applying optimal distribution, rate increased by 4～5% compared cases uniform tube- distributions, distributions considered this study.Keywords:Fin-and-tube evaporator(휜-튜브 증발기), Simulation(시뮬레이션), Capillary tube(모세관), Distributor(분배기), Air distribution(공기유속 분포) †Corresponding author Tel.: +82-2-2220-0426; fax: +82-2-2295-9021 E-mail address: ksleehy@hanyang.ar.kr
