家用太阳能热水系统能效系数CTP测试数据

能效标准和能效标识可提高用能产品的能源效率，促进节能技术进步，进而减少有害物的排放和保护环境。本数据可以对家用太阳能热水系统能效系数CTP进行评价，为政府监管和消费者购买提供参考和技术支撑。1、家用太阳能热水系统能效系数CTP按如下公式进行计算：CTP=Qs(e)/Qs(m)-α•Usl(e)/Usl(m)，其中Qs(e)为试验条件下测试所得的家用太阳能热水系统单位轮廓面积日有用得热量，单位为MJ/m2；Qs(m)为GB/T19141或GB/T26970规定的家用太阳能热水系统单位轮廓面积日有用得热量最小值，单位为MJ/m2；α为权重系数取0.9；Usl(e)为试验条件下测试所得的家用太阳能热水系统的平均热损因数，单位为W/m3•K；Usl(m)为GB/T19141或GB/T26970规定的家用太阳能热水系统的平均热损因数最大值，单位为W/m3•K；2、数据分析：将以上数据按照GB 269691-2011《家用太阳能热水系统能效限定值及能效等级》要求，根据不同类型热水系统的能效系数（紧凑式、分离直接式、分离间接式、闷晒式）进行判定等级

Energy efficiency standards and energy efficiency labels can enhance the energy efficiency of energy-using products, advance energy-saving technological progress, and thereby reduce harmful pollutant emissions and protect the environment. This dataset can evaluate the energy efficiency coefficient CTP of domestic solar water heating systems, providing reference and technical support for government supervision and consumer purchasing decisions.

1. The energy efficiency coefficient CTP of domestic solar water heating systems is calculated via the following formula:
CTP = Qs(e)/Qs(m) - α*Usl(e)/Usl(m)
Where:
- Qs(e): Daily useful heat gain per unit contour area of domestic solar water heating systems measured under test conditions, with the unit of MJ/m²;
- Qs(m): Minimum value of daily useful heat gain per unit contour area of domestic solar water heating systems specified in GB/T 19141 or GB/T 26970, with the unit of MJ/m²;
- α: Weight coefficient with a fixed value of 0.9;
- Usl(e): Average heat loss factor of domestic solar water heating systems measured under test conditions, with the unit of W/m³·K;
- Usl(m): Maximum value of the average heat loss factor of domestic solar water heating systems specified in GB/T 19141 or GB/T 26970, with the unit of W/m³·K;

2. Data analysis: Classify and grade the energy efficiency coefficients of different types of hot water systems (compact type, separate direct type, separate indirect type, unglazed flat-plate type) in accordance with the requirements of GB 269691-2011 *Energy Efficiency Limited Values and Energy Efficiency Grades of Domestic Solar Water Heating Systems* using the above data.
