干旱区水上太阳能电池板与浮球联合作用对节水效率的影响

Combined Effect of Solar Panels and Floating Balls on Water Saving Efficiency in Arid Areas

干旱区太阳能资源丰富、降雨量少、蒸发强烈、水资源匮乏,为进一步缓解干旱区水资源匮乏问题,利用浮球作为防蒸发材料,结合太阳能电池板对水面的遮挡作用,分析太阳能电池板遮挡下各月份蒸发抑制率和太阳能电池板与浮球联合作用下的抑制率。一整年内太阳能电池板遮挡下的水面蒸发抑制率随时间变化先增大后减小,7月份达到最大值为40.2%,1月份达到最低值为12.1%;在非冰冻期内,太阳能电池板与浮球联合和无遮挡下围栏蒸发抑制率7月份达到最大分别为88.6%、86.8%,4月份最小分别为85.0%、80.6%,冰冻期水面蒸发抑制率为91.1%。太阳能电池板与浮球联合下比太阳能电池板遮挡下蒸发抑制率提高了57.9%。

In arid areas,there are abundant solar energy resources,little rainfall,strong evaporation,and lack of water resources.In order to further alleviate the problem of water resources shortage in arid areas,floating balls are used as anti-evaporation materials.Combined with the shielding effect of solar panels on the water surface,solar panel shielding is analyzed.The evaporation inhibition rate and the inhibition rate under the combined action of solar panels and floating ball in each month are also analyzed.In a whole year,the water surface evaporation inhibition rate under the shade of solar panels first increases and then decreases with the time,reaching the maximum value of 40.2%in July and the lowest value of 12.1%in January;During the non-freezing period,the maximum evaporation inhibition rates of the fence under the combination of solar panels with floating ball and unobstructed were 88.6%and 86.8%in July,and the minimum values were 85.0% and 80.6%in April,respectively.The evaporation inhibition rate of water surface was 91.1%during freezing period.The evaporation inhibition rate under the solar panel and the floating ball is 57.9% higher than that under the shade of the solar panel.
