太阳能热水器贮热水箱结束时水的温度测试数据

贮热水箱结束水温是太阳能热水器重要参数之一，贮热水箱内结束水温过低会影响消费者实际使用，造成用户对节能产品的不信任。本数据可以对太阳能热水器的结束水温进行评价，为政府监管和消费者购买提供参考和技术支撑。1、太阳能热水器贮热水箱结束时水的温度t17按如下公式进行计算：t17=20+17*（te-tb）/H，其中tb为集热试验开始时贮热水箱的水温，单位为℃；te为集热试验结束时贮热水箱的水温，单位为℃；H为累计辐照量，单位为MJ/m2；2、数据分析：将以上数据按照GB/T 19141-2011《家用太阳能热水系统技术条件》要求，太阳辐照量为17MJ/(m2•d)时，贮热水箱内集热结束时水的温度≥45℃，贮热水箱结束时水温大于等于45为符合，小于45的为不符合。The final water temperature of the hot water storage tank is one of the critical parameters for solar water heaters. An excessively low final water temperature in the storage tank will compromise consumers' actual usage experience and erode their trust in energy-saving products. This dataset enables the evaluation of the final water temperature of solar water heaters, providing reference and technical support for government regulatory work and consumers' purchasing decisions. 1. The final water temperature t17 in the hot water storage tank of a solar water heater is calculated using the following formula: t17 = 20 + 17*(te - tb)/H, where tb denotes the water temperature in the storage tank at the start of the heat collection test, in units of ℃; te denotes the water temperature in the storage tank at the end of the heat collection test, in units of ℃; H denotes the cumulative solar irradiance, in units of MJ/m²; 2. Data analysis: Per the requirements specified in GB/T 19141-2011 Technical Specifications for Domestic Solar Hot Water Systems, when the solar irradiance is 17 MJ/(m²·d), the final water temperature in the storage tank upon completion of heat collection shall be ≥45℃. A final water temperature of 45℃ or above is deemed compliant, while a temperature below 45℃ is deemed non-compliant.
