摘要: 储水式电热水器带有温控器和热保护器控制温度,具有安全性能较高、使用方便等优点。随着储水式电热水器的普及,作为常见的大功率家电产品,它的能耗备受人们的关注。24 h固有能耗系数是储水式电热水器重要的能耗指标之一,是人们购买电热水器产品比较的重要参数。对电热水器的24 h固有能耗指数测试的不确定度进行分析,为提高电热水器能效测试的准确度提供参考。

关键词: 储水式电热水器, 24 h固有能耗系数, 不确定度

Abstract: The electric storage water heater is equipped with a thermostat and a thermal protector to control the temperature, and has the advantages of high safety performance and convenient use. With the popularity of electric storage water heaters, as a common high-power household appliance, its energy consumption has attracted much attention. The coefficient of standing per 24 h is one of the important energy consumption indicators of electric storage water heaters, and it is an important parameter for people to compare electric water heater products. Analyzes the uncertainty for the coefficient test of standing loss per 24 h of electric water heaters, and provides a reference for improving the accuracy of energy efficiency testing of electric water heaters.

Key words: Electric storage water heater, Coefficient of standing loss per 24 h, Uncertainty
