【摘要】：針對不同室內(nèi)氣流組織下空氣溫度分布特征的差異,首次建立單層非晶硅半透明光伏窗二維穩(wěn)態(tài)傳熱模型,并驗證模型的可靠性。在此基礎上,采用數(shù)值模擬的方法,研究比較2種典型室內(nèi)氣流組織下單層非晶硅半透明光伏窗的傳熱性能。結果表明,分層空調(diào)系統(tǒng)中光伏窗表面溫度垂直梯度分布明顯,接近2.2℃/m;而混合通風系統(tǒng)下光伏窗表面溫度則沿送風氣流流動方向顯著增加。在模擬工況下,增加送風速度有利于降低光伏模塊的工作溫度,改善運行工況,但效果并不顯著。夏季工況下,增加送風速度不利于減少光伏窗室內(nèi)得熱。對于不同氣流組織不同季節(jié)工況下,應采取不同措施優(yōu)化光伏窗的運行工況。
[Abstract]:Aiming at the difference of air temperature distribution in different indoor airflow, the two-dimensional steady state heat transfer model of single layer amorphous silicon translucent photovoltaic window is established for the first time, and the reliability of the model is verified. On this basis, the heat transfer performance of monolayer amorphous silicon semitransparent photovoltaic window with two typical indoor airflow was studied by numerical simulation. The results show that the vertical gradient distribution of the surface temperature of photovoltaic window is obvious in stratified air conditioning system, which is close to 2.2 鈩，
