摘 要:用自制的炭黑水泥砂漿板制作室內地面并以此進行了低溫輻射采暖的試驗研究。介紹了炭黑水泥砂漿板在室內的排布、接線、溫度測點的布置,給出了在恒定電壓下室內空氣溫度、加熱板溫度、隔熱層溫度等隨通電時間變化的試驗結果,研究了電流變化的規律以及多次電熱試驗后加熱板電阻的穩定性。實驗表明,炭黑水泥砂漿板通電后產生的熱量完全可滿足室內采暖的需要,室內的溫度分布均勻,且地板能蓄熱因而有利于維持室內環境的熱穩定。在通電過程中以及在多次通斷電時,電阻基本穩定,電熱功率穩定。
Abstract: An interior floor is developed by using of author's cement-carbon mortar plates and the tests on thermal radiation of it are carried out. Here, the distribution of plates, the linking scheme for each plates and the position of thermal-measuring points are introduced; the test rezults on relationship between electro-passed time and temperature, where including at different places of room, on top of heating plate and under insulated plates, are reported; the stability of electric current and resistance, after many times of switch on or off, is experimentally researched. The tests show that, for the quantity of heat that produced by cement-carbon mortar plates, it is able to completely meet the demands for supplying heat, and the temperature distribution in room is even. As the plates can store heat, so that is profitable to keeping the room temperature for unchanging. During the electricity is in turn on and after many times of switch off or on, the electric resistance and power are keep stable.
