解决方案

在设计系统和构造时考虑到的参数

  • 辐射末端的布置和尺寸 - 地面供热/供冷区 的面积越大,供水温度可越低。
    1. Size of 地面供热/供冷区


    更多信息,见: 供热/供冷区
  • 当使用热泵作为热源时,其可提供的最高供水温度
  • 最大回路长度 - 将影响水流量和分集水器的规格,从而影响运行费用和前期投资。
    2.最大长度

  • Perimissible pipe spacing - has effect on mean surface temperature of radiant heater.
    3. Pipe spacing

  • Insulation thickness under radiant heater - has effect on 辐射供热的热损失(向建筑之外).
    4. Insulation layer

  • Selection of proper 装饰层 in rooms - has effect on radiant heater efficiency and on uniform temperature distribution on heater surface.
    5.装饰层

PARAMETERS THAT CAN BE SET/ADJUSTED IN COMPLETED SYSTEM

  • Supply temperature, if a system with adjustable temperature is used (e.g. gas-fired water heater with a mixer or a mixing pump set)
    6. Supply temperature

  • Maximum flow rate in floor heating loops - possible by adjusting Δθ 最小 内区, Δθ 最大 内区, Δθ 最小 外区 and Δθ 最大 外区 or by specifying 供回水温差.
    7. Parameters that have effect on maximum flow rate in floor heating loops
