Analysis on Thermal Performance of Low-temperature Water Radiant Floor Heating System

With the development of heating technology and improvement of building function and people's living standard,an heating mode which is economic,practical,environmental and reliable is paid more attention to.A new heating mode-low temperature water radiant floor heating was investigated.Geometrical and mathematic models were established.To analyze on heat transfer,the new heating mode was compared with traditional heating mode-radiator heating.Then advantages of this new heating mode were clarified.Furthermore,the theoretical basis on interior temperature 2℃ lower than radiator heating was opened out for this new heating mode.The theoretical research on low-temperature radiant floor heating was perfected.And it can provide basis for exploiting and improving the new heating technology.
