Study of environment thermal state on working places in hot workshops

To protect the workers from stress with radiation heat in workshops, a study of the environment thermal state has been carried out. A local air supply to the workplace was provided through an air shower located either above the workplace or close to its floor. Operating measurements of thermal conditions were made along with an evaluation by using the WBGT(wet bulb globe temperature) index.The results of measurements and flow visualization show that the upper air shower is more suitable than the lower one.The optimum local air supply for hot workshops has been designed.
