将预制的炭黑水泥砂浆板埋入地面制成了室内电热采暖地面,现场测试了其在持续工作252后时地面砖、炭黑水泥砂浆板、隔热板、室内空气温度的变化规律和耗电量等。结果表明,炭黑水泥砂浆板、温控器、电源等构成的系统能在较长测试时段内可靠地实现室内采暖;室内控制温度越高,1个工作周期内发热板工作时间越长,每天的耗电量也越大;在此过程中,炭黑水泥砂浆板电阻变化较小,电功率稳定。
The prefabricated carbon black cement mortar board was buried in the ground to make the indoor electric heating floor. The on-site test of its continuous work after 252 when the floor tiles, carbon black cement mortar board, insulation board, indoor air temperature changes and consumption Power and so on. The results show that the system composed of carbon black cement mortar board, thermostat, power supply and so on can reliably realize the indoor heating in a long test period. The higher the indoor control temperature, the longer the working time of the heating plate in one working cycle, The greater the power consumption; in the process, the change of resistance of the carbon black cement mortar board is small, and the electric power is stable.
