Analysis on Heat Transfer Coefficient of a PCM-glazed Unit

Abstract

Abstract: A coupled heat transfer model of phase change, radiation and heat conduction at steady state under solar irradiation in a semitransparent PCM-glazed unit was developed. Interior energy transfer of PCM-glazed unit was simulated with controlling volume method and Bouguer-Beer Law. Effects of radiation physical parameters, internal and external environment on heat transfer coefficient were investigated.It shows that it is necessary to consider semitransparent property of PCM-glazed unit as calculating heat transfer coefficient.Except for radiation physical property and environment, liquid fraction and light transmittance of PCM affect heat transfer coefficient as well.

Key words: heat transfer coefficient, PCM, glaze unit, coupled heat transfer
