Title
(EN) Water tank heating method and device, electronic equipment and solid oxide fuel cell (SOFC) system
(ZH) 一种水箱加热方法、装置、电子设备及SOFC系统
Abstract
(EN) The invention provides a water tank heating method and device, electronic equipment and a solid oxide fuel cell (SOFC) system. Ice in a water tank is already heated before the SOFC system is started,the temperature of the ice already rises, and after the SOFC system is started, the heating time for heating the ice heated already again can be shortened, that is, the thawing time of the water tankcan be shortened. Further, in the ice heating process, the preset SOFC thawing required time determined according to the current electric pile outlet temperature is used as one parameter for heating control, the electric pile outlet temperature is a key factor which affects the starting time of the SOFC system, the preset SOFC thawing required time corresponding to the electric pile outlet temperature is used as one parameter for heating control to perform heating control, and the accuracy of heating control is higher.
(ZH) 本发明提供了一种水箱加热方法、装置、电子设备及SOFC系统,本发明在SOFC系统启动之前已经对水箱中的冰进行了加热,冰的温度已经升高了,则在SOFC系统启动后,对已经升温的冰再次加热的加热时间,即水箱解冻时间会缩短。进一步,本发明在对冰加热过程中,使用了依据当前的电堆出口温度确定的预设SOFC解冻所需时间作为加热控制的一个参数,由于电堆出口温度是影响SOFC系统启动时间的关键因素,则使用该电堆出口温度对应的预设SOFC解冻所需时间作为加热控制的一个参数来进行加热控制,加热控制的准确度会更高。
