Abstract
為驗證溫室環境模式之準確性與通用性，在此研究中量測兩型溫室在各種環境狀況下的微氣候數據，由於不同文獻之參數值有顯著差異性，少數部份數據用以修正模式之參數值，多數之量測值用以驗證模式的預測能力，模式對溫度預測的準確性約2°C，相對濕度值的預測誤差小於5％，模式的時間不相關性假設條件對兩型溫室均可成立，利用敏感性分析對於參數值進行模擬試驗，其結果顯示遮蔭裝置為國內溫室作業必須具有的設備，利用蒸發冷卻法之降溫能力取決於進入溫室內太陽能量，外在空氣之相對溫度值與所用設備之作業效率，以自然通風或機械通風之溫室的降溫極限在於大氣之乾球溫度，利用蒸發冷卻法之降溫效果無法低於大氣濕球溫度。
In order to verify the accuracy and flexidility of the greenhouse environmental model, amount of data of microclimate for two type plastic greenhouses were collected at various conditions. Some of data were used to calibrate the numerical values of model parameters because those values from several literatures were different singificantly. Most of the measurement data were adopted to check the predictive ability of this model. The accuracy of the predicted temperature was nearly 2℃. The deviations of relative humidity were within 5%. The assumption of time-depentent for this model was valid. Numerical experiments were conducted to test the sensitivity of the model to some parameters.
