In winter, heat is transferred from

In winter, heat is transferred from indoor air to the inner surface of external wall by convection. Then, this heat is transferred from the inner surface to the outer surface by conduction. At last, this heat is transferred from the outer surface to outdoor air by convection [7]. According to the fact that the heat transferring from indoor air to outdoor air is equal to that transferring from indoor air to the inner surface of external wall, the temperature of inner surface of external wall can be calculated, which can be considered as the dirichlet boundary condition of external wall. The temperature of interior wall is set as same as the indoor design temperature.

結果 (繁體中文) 1:

在冬季時，熱量從室內空氣通過對流傳遞至外壁的內表面上。然後，該熱量從所述內表面通過傳導傳遞到外表面。最後，該熱量從外表面通過對流[7]轉移至室外空氣。根據這樣的事實，將熱量從室內空氣向室外空氣傳送等於從室內空氣轉移到外壁的內表面，外壁的內表面的溫度可以被計算，其可以被認為是狄利克雷邊界外壁的條件。室內壁的溫度被設置為一樣的室內設計溫度。

在冬季，熱量通過對流從室內空氣轉移到外牆內表面。然後，通過傳導將熱量從內表面傳輸到外表面。最後，這種熱量通過對流從外表面轉移到室外空氣[7]。根據室內空氣向室外空氣的傳熱等於從室內空氣向外牆內表面的傳遞，可以計算出外牆內表面的溫度，可視為外牆的二元邊界條件。內牆溫度與室內設計溫度相同。

冬季，熱量通過對流從室內空氣傳遞到外牆內表面。然後，熱量通過傳導從內表面轉移到外表面。最後，這種熱量通過對流從外表面轉移到室外空氣中[7]。根據室內空氣向室外空氣的傳熱與室內空氣向外牆內表面的傳熱相等的事實，可以計算出外牆內表面的溫度，作為外牆的dirichlet邊界條件。內牆溫度按室內設計溫度設定。
