室內空氣層的隔熱原理與應用

從 Rick Owens 與 Adidas 的充氣運動衫聯乘出發,拆解香港住宅單靠空氣層是否等於隔熱的物理限制與常見謬誤。

早兩日睇到 Rick Owens 同 Adidas 合作嘅充氣運動衫,用內置風扇將體感溫度降低 13°C,不禁令我諗起近年室內設計成日有人問嘅問題:喺香港呢度又濕又熱,係咪加個空氣層就等於隔熱?答案唔係咁簡單。

空氣係好嘅隔熱體,但唔係萬能

Nike 嘅設計總監講過:「空氣係一種隱形嘅神奇材料。」確實,靜止空氣嘅導熱率極低,所以雙層玻璃、空心磚、甚至羽絨外套都係靠空氣層保暖。不過,當我哋將呢個概念搬入家居,成日會忽略兩個物理限制:空氣層厚度同氣密性。太薄(20mm)又會引發對流,令隔熱效果打折。香港常見嘅中空玻璃,如果入面冇填充惰性氣體,夏天西斜時依然會辣手。

拆解三個常見謬誤

講到底,香港住宅先天樓底矮、通風有限,妄想單靠一個靜止空氣層就解決曬所有問題,係不切實際嘅。好多時要結合機械通風(例如窗式通風器)同埋物料嘅熱質量(例如混凝土儲冷),先至做到真正嘅舒適。
