1、Good is good, but better carries it.精益求精，善益求善。复件水箱容量及采光面积-水容量及采光面积XXXX太阳能有限公司一、 目录水容量及采光面积在国标中的描述二、 水容量及采光面积的计算三、 原先制定水容量及采光面积的数值四、 现有水箱实际水容量及采光面积的数值五、 实际水容量及采光面积与标称相差百分比六、 新编水容量及采光面积数值七、 未能解决的水容量及采光面积型号可采用的解决方法水容量及采光面积在国标中的描述容量要求：出口敞开式和开口式贮热水箱的容水量标称显示值与测量值的偏差在5.0%以内。检测方法：用水温不高于30的水将水箱充满至系统溢流口出水，将水箱
2、排气口或者顶部的安全阀打开，从贮热水箱的出口处放水测量的质量，环境温度039，贮热水箱标志中贮热水箱标称值V1与容水量的测量值V的偏差率V按下式计算，此处水的密度取1000Kg/mV=x100%采光面积:标称轮廓采光面积与实际轮廓采光面积的偏差应在3.0%以内。检测方法：AC=Lx（n-1）xS+DL为有效集热长高度，n为真空管支数，S为孔距，D为真空管直径。AC=x100%水容量及采光面积的计算计算水容量：S底面积=r2S扇形面积=（n/360）xS底面积S三角形形面积=底x高2S弓形面积=S扇形面积-S三角形形面积V理论水容量=S底面积xh内水箱V弓形水容量=S弓形面积xh内水箱V实际水容
