Experimental research of a new radiant heating floor and wall structure with low temperature hot water

Presents the new radiant heating floor and wall structure and establishes the experimental system. Researches thermal properties of floor radiant heating with wood floor and ceramic tile and wall radiant heating with perforated honeycomb aluminum plate and imperforated honeycomb aluminum plate by experiment. The results show that, for wall radiant heating, the temperature and the heat flux of perforated honeycomb aluminum plate are higher than those of imperforated honeycomb aluminum plate; for floor radiant heating, the temperature and the heat flux of ceramic tile are higher than those of wood floor. The radiant heating ratio is more than 57 percent for floor radiant heating, and 65 percent for wall radiant heating.
