Indoor comfort simulation analysis and optimization of air-conditioned rooms based on PMV

Air distribution in air-conditioned rooms is an important factor affecting comfort. Simulates numerically the air distribution and thermal environment in an air-conditioned room under heating conditions in winter with STAR-CCM+ software, analyses the velocity field and temperature field around the mannequin, and calculates the PMV with theoretical method. The results show that, when the wind deflector angle is at the default heating angle of 53 degrees, the overall PMV of human body is high, and the comfort is poor, when the default wind deflector angle is optimized to 28 degrees, the comfort is significantly improved.
