摘要：

A　wind　tunnel　was　applied　to　investigate　the　frost　characteristics　under　variable　frost　conditions:　air　temperature　10.5°C,　relative　humidity　80%,　wind　speed　3　m/s,　cold　surface　temperature　varying　from　-3.5°C　to　-19.7°C.　The　characteristics　of　each　dynamic　frosting　processes,　such　as　frost　layer　growth　rate,　defrosting　frequency,　frost　layer　thickness,　frost　weight,　frost　density　and　frost　thermal　coefficient　of　frosting　process　were　analyzed　in　detail.
