中文摘要 | 組培瓶內空氣溫度為植株成長之顯著影響因子,此研究中推衍一個組織培養瓶之 熱傳模式。瓶內熱源主要來自燈光之能量,瓶內逸出之能量包括傳導、對流與輻射能量,為 驗証此模式,利用兩種不同形狀的組培瓶在不同光源能量下量測其空氣溫度分佈。 以 T 型 熱偶線配合數據記錄器以量測溫度, 模式預測值與實際量測值之差異數值在 0.5 ℃以內, 誤差絕對值的平均值低於 0.4 ℃。 藉由增加通過組培瓶外側的風速用以增加熱流係數可以 有效減少此種組培瓶在光源下之溫室效應。 |
英文摘要 | The air temperature within the culture vessels is the dominant factor to influence the growth of plantlets. A thermal transfer model of tissue culture vessel was developed in this study. The heat source of vessel was obtained from the radiation energy of fluorescent tubes. The energy emitted from the vessel included convective and radiative heat exchanges. In order to validate the model, two types of culture vessels were selected to determine the air temperature distribution at various light radiation energy. T-type thermocouples connected with data logger were adopted to measure these temperatures. The discrepancies of the predictive values with actual measurement values are less than 0.5 ℃. The average absolute error is lower than 0.4 ℃. Increase the surface convection coefficient by increasing of ventilation velocity could reduce effectively the greenhouse effect in these small size culture vessels. |
