摘要
该平台以GB/T39288—2020《蓄热型电加热装置》中提出有关固体电热储能装置的热工性能测试方法及流程为蓝本,参考了国内外标准,专门针对固体电热储能装置,进行纯储热工况、纯放热工况、边储边放工况全工况测试,改善并补充了固体电热储能装置热工与储能性能测试。该平台改进了GB/T 39288—2020的试验流程,结合非制热状态下的放热测试和制热状态下的放热测试,能够进行固体电热储能装置热工与储能性能标准测试。为了验证该平台可靠性,对某固体电热储热装置进行一次标准测试,记录其试验时的电量、时间、温度等参数,画出试验时温度曲线、加热丝电流电压曲线、热输出负荷曲线,通过改进、补充的公式计算了固体电热储能的热工与储能性能;利用计算结果画出了在额定热输出功率下的储能性能图。该图清晰展示了固体电热储能装置的有效释放的温度范围,储能能力,以及能量利用情况。本次测试结果与理论值、经验值相近,证明该平台可以作为设备商自检或教学使用的测试平台。该平台还留有自定义热负荷曲线功能,可以帮助教学者和学习者在真实的工况下,对固体电热储能装置进行研究和学习。
A platform is designed based on the thermal performance testing methods and testing processes of solid electric heat storage devices proposed in Thermal Storage Electric Heating Devices(GB/T39288—2020).By referring to domestic and foreign standards,the platform can test full working conditions(including the pure heat storage condition,pure heat release condition,and storage and release conditions),with improved the thermal and energy storage performance testing for solid electric heat storage devices.The platform can carry out the standard thermal and energy storage performance test for the solid electric heat storage device by improving the test procedures of GB/T 39288—2020 combined with the heat release testing under both non-heating and heating states.To verify the reliability of the platform,one standard test is conducted on a solid electric heat storage device.The platform records the parameters such as electricity,time,and temperature during the test;draws the temperature curve,heating wire current-voltage curve,and heat output load curve during the test;and calculates the thermal and energy storage performances of the solid electric heat storage through improved and supplemented formulas.Based on the calculation results,the energy storage performance diagram is drawn under the rated thermal output power.The diagram clearly shows the effective release temperature range,energy storage capacity,and energy utilization of the solid electric heat energy storage device.The result of the test is found close to the theoretical value and empirical value,which proves that the platform can be used for self-inspection or teaching by equipment manufacturers.The platform also has the function of displaying user-defined heat load curves.This function can help teachers and learners research and learn solid electric heat energy storage devices under real working conditions.
