| Abstract: | Developed a radiation model of radiant floor cooling combining with displacement ventilation in the air conditioned room.Used fluent software and simulated the thermal-humidity distribution at indoor. At the maximum of cooling load of the indoor,simulated velocity field,temperatare field and humidity field in isothermal and not isothermal suppling air with the different temperature of the floor. Using PMV-PPD thermal comfort index,analysed parameter change of the air-conditioning system in basically satisfing human body in thermal comfort. |
