Abstract：

In　this　paper,　the　dynamic　frosting　characteristics　on　cold　flat　surface　in　different　air　temperature　and　humidity　conditions　are　investigated　numerically.　The　variation　range　of　air　temperature　and　relative　humidity　are　respectively-10∼10　°C　and　50%∼90%,　which　is　the　most　common　frosting　condition.　The　simulation　results　of　frosting　characteristics　including　the　parameters　of　frosting　rate,　frost　thickness,　frost　density,　thermal　conductivity　of　frost　layer,　frost　surface　temperature　and　heat　flux　variation　with　the　frosting　time.　These　results　provide　valuable　references　to　design　suitable　defrost　control　strategies　for　air　source　heat　pump　used　in　different　areas.　©　2011　IEEE.
