摘要
本文通过实验研究了对流式电加热器和辐射板式电加热器加热过程中的升温规律、室内温度分布规律以及温控装置的运行效果。自然对流电加热器,室内升温较慢,但温度分布均匀;强制对流电加热器,室内升温快,但温度波动较明显;辐射板式电加热器室内升温情况与安装位置无关,但室内温度分布与安装位置关系密切。三种电加热器温控装置的稳定性和可靠性均良好。
Experiments were made to study the temperature rising law in the heating process,the indoor temperature distribution and the operation of temperature control devices of convection electric heater and radiation-plate electric heater. Results show that the natural convection electric heater is with low temperature rising and uniform indoor temperature distribution, and the mechanical one with rapid temperature rising and significant fluctuations in temperature. To the radiation-plate electric heater, the installation location has nothing to do with indoor temperature rising, but has a lot to indoor temperature distribution. Temperature control devices of all are good at stability and reliability.
