【Abstract】 Based on the method of computational fluid dynamics (CFD), using the finite volume method, simulates and analyses the temperature field, velocity distribution and thermal comfort of human body in displacement ventilation (DV) systems with and without cooled ceiling (CC). The results indicate that CC/DV system can reduce indoor temperature gradient and improve human thermal comfort.更多还原
