摘要

为了探究环境因素对二叉树冷却通道光伏光热(photovoltaic/thermal

PV/T)集热器性能的影响

基于PV/T集热器的能量转换过程

建立了系统传热的理论模型

研究了光伏组件表面及冷却流体的温度分布规律

分析了环境因素对系统电效率的影响。结果表明:辐射强度每升高100 W/m

光伏组件表面温度升高约1.95 K

系统电效率下降约0.13百分点

流体温度分布存在明显差异;随着倾斜角度由15°增至60°

光伏组件表面辐射强度表现为上凸曲线形式

由829.26 W/m

先升至870.12 W/m

后降至824.13 W/m

于35°附近达到最大值

表面平均温度与表面接收辐射强度变化一致

而系统电效率表现为下凹曲线形式

于35°附近达到最小值;环境温度每升高5 K

外部辐射温度升高约7.2 K

光伏组件表面平均温度升高约0.5 K

系统电效率下降约0.04百分点;随着环境风速由0 m/s升至2 m/s

系统电效率的变化仅在0.1百分点以内

但环境风速及温度的变化对光伏组件散热效果的影响不显著。

Abstract

In order to explore the influence of environmental factors on the performance of photovoltaic/thermal (PV/T) collector with binary tree-shaped cooling channels

based on the energy conversion process of PV/T collector

a theoretical model of system heat transfer was established

the temperature distribution law of PV module surface and cooling fluid was studied

while the influence of environmental factors on the system electrical efficiency was analyzed. Results show that

for every 100 W/m

increase in irradiation intensity

the surface temperature of PV module is increased by about 1.95 K

the syst

em electrical efficiency is decreased by about 0.13 percentage points

and there is a significant difference on the temperature distribution of cooling fluid. As the inclination angle increases from 15° to 60°

the irradiation intensity on the PV module surface shows an upward convex curve trend

rising from 829.26 W/m

to 870.12 W/m

at first and then decreasing to 824.13 W/m

and reaching its maximum value at around 35°. Meanwhile

the average temperature of surface is consistent with the change in the irradiation intensity received by the surface. But the system efficiency shows a downward concave curve trend

reaching its minimum value at around 35°. For every 5 K increase in ambient temperature

the external radiation temperature is increased by about 7.2 K

the average temperature of PV module surface is increased by about 0.5 K

and the system electrical efficiency is decreased by about 0.04 percentage points. As the ambient wind speed increases from 0 m/s to 2 m/s

the variation of system electrical efficiency is only within 0.1 percentage points. However

the changes of ambient wind speed and temperature have no significant impact on the heat dissipation effect of PV module.
