Abstract

Abstract:

The sensitivity analysis of main configuration parameters of water-type PV/T module including thickness of cover glass, thickness of air gap, thickness of thermal absorber, diameter of water tube, spacing of water tube and thickness of thermal insulation material has been conducted using normalized sensitivity coefficient method. The impact of solar radiation, outdoor air temperature and flow rate on sensitivity coefficients of these configuration parameters are also investigated. It indicates that thickness of cover glass, diameter of water tube and spacing of water tube are significant influence parameters in term of electrical power generation and thermal heat for hot water. Compared with solar radiation and flow rate, effect of outdoor air temperature on sensitivity coefficients is not obvious.

Key words: water-type PV/T module, sensitivity analysis, configuration parameter, normalized sensitivity coefficient method

摘要：

采用归一化敏感系数法对热水型PV/T组件的主要结构参数(盖板玻璃厚度、空气腔厚度、集热板厚度、水管直径、水管间距和保温材料厚度)进行了敏感性分析。研究了太阳辐射值、室外温度和流速对各结构参数敏感系数的影响规律。结果表明,盖板玻璃厚度、水管直径和水管间距是影响热水型PV/T组件发电量和热水得热量的显著性参数。与太阳辐射值和流速相比,室外温度对结构参数的敏感系数影响不明显。
