dc.description.abstract | As a comfortable and energy-efficient air conditioning system, the application of floor radiant heating system is used increasingly greatly in the north of China. As a result, the feasibility of floor radiant cooling has gained more attention. To examine the thermodynamic performance of the floor radiant cooling system, we measured the operational conditions including the minimum floor surface temperature, the cooling capacity, and the indoor temperature field distribution under different outdoor temperatures in Beijing. Because the ground temperature changes with the mean temperature of the supplied and returned water and room temperature, the mean temperature of the supplied and retuned water was obtained. Finally, we analyzed the phenomenon of dewing and developed measures for preventing it. The dry air layer near the floor formed by a displacement ventilation system can effectively prevent dews on the surface of the floor in the wet and hot days in summer. In addition, for the sake of the displacement ventilation system, the heat transfer effect between floor and space is enhanced. Our analysis pointed out that floor radiant cooling system combined with displacement ventilation ensures good comfort and energy efficiency. | en |
