The model of the main control room was established based on the finite volume method and the PMV index was applied to investigate the thermal comfort inside the main control room. The results indicate that people inside the main control room have poor thermal comfort level and a feeling of cold. On the basis, three methods including increasing the air inlet temperature, decreasing the air flow rate and adjusting the air inlet angle were applied to improve the people thermal comfort level. It is found that the room thermal comfort level is significantly improved by increasing the a
