Abstract
In this paper, the background temperature and manikin thermal sensation obtained by the experiment and simulation under three conditions were compared. The boundary conditions required by CFD simulation were set with the experimental data, and the model was adjusted to verify the accuracy of the simulation. The simulation results showed that both local radiant panels and desk fan could effectively reduce the mean skin temperature (MST) and thermal sensation of manikin. In addition, when both facilities were turned on, the manikin’s MST dropped further. Two kinds of facilities were optimized, respectively, and the respective parameters were obtained when the MST of manikin dropped to the thermal neutral level. In order to avoid the problem of condensation and draft risk, the two kinds of facilities were optimized at the same time, and the respective parameters were obtained when the MST of manikin dropped to the thermal neutral level, and the problems of condensation and draft risk were also avoided.
