NUMERICAL STIMULATION OF RADIANT FLOOR HEATING WITH DISPLACEMENT VENTILATION

摘要：

Radiant floor heating has received the increasing attention due to the wide advantages, especially the energy saving as compared to the conventional airconditioning system. This study presents a numerical investigation of radiant floor heating with the displacement ventilation in the room. The air isotherms and flow patterns with and without displacement ventilation, as well as the heat fluxes along the radiant floor and outer wall are obtained. The results show that the average temperature in the room with lateral air supply is higher than that without air supply but lower than that with ceiling air supply, which indicates that displacement ventilation is beneficial for increasing the indoor air temperature by enhancing convective heat transfer and air quality by offering fresh air. The results are greatly significant for the development and application of the radiant floor heating.
