16、对流体流速的影响所致;叠加式PV/T集热器效率较交叉式PV/T集热器高,但交叉式PV/T集热器应用更灵活。Evaluation only.Created with Aspose.Slides for .NET 3.5 Client Profile 5.2.0.0.Copyright 2004-2011 Aspose Pty Ltd.Evaluation only.Created with Aspose.Slides for .NET 3.5 Client Profile 5.2.0.0.Copyright 2004-2011 Aspose Pty Ltd.不足和展望1.PV/T集热器组合方式较
17、少,尚难找到完美的利用方式以最大化太阳能综合利用效率;2.由于条件限制,本研究中的光热热效率测试实验中的模拟水箱保温效果不够好;本实验不能测出即时的太阳能辐射强度,这对实验结果也有一定影响。不足:展望:1.将研制出成本更低、效率更高的太阳能电池;2.可将太阳能光热组件的集热管换成透明的玻璃管,并将太阳能电池包裹在玻璃管下半部分,同样可以利用太阳能同时产生电、热两种收益;3.太阳能必将成为人类生产生活的主要能源。Evaluation only.Created with Aspose.Slides for .NET 3.5 Client Profile 5.2.0.0.Copyright 2004
