Abstract: | 本文以實驗方法探討窗型冷氣機之季節性能源效率比值(Seasonal Energy Efficiency Ratio,SEER)。實驗在環境控制室中進行,並以二台冷氣能力不同之窗型冷氣機為測試對象。在實驗方法上,室內及室外側可改變環控室之溫度及相對濕度;運轉狀況可改變循環率及開啟時間比,探討不同條件對EER及SEER的影響。
實驗結果發現,EER隨室外溫度變化最為顯著,室外溫度越低,系統之EER值越高;在高循環率及低開啟時間比時,系統的冷凍能力損失最大;當開啟時間比為0.5時,效率低落最小,系統有最佳之SEER值;平均外氣溫度較低的地區,該區之SEER值較佳;平均外氣溫度越低的方案,其SEER值越高;由實際實驗所得之SEER較美、日簡易計算法所得之SEER高。 When outdoor temperature is increase,EER is decrease;When indoor temperature is increase,EER is increase;When outdoor relative humidity is increase,EER is decrease. In higher cycling rate or lower fraction on time,the system has more capacity losses.Fraction on-time at 0.5,the coefficient of degradation is smallest,SEER is the best.When the location average outdoor temperature is lower,SEER is higher. |
