Abstract
To evaluate the effectiveness of using a vest with fans for working in an air-conditioned room using CFD analysis, this paper conducted an analysis that introduced a model construction and a human body thermal model. The shape of the human body and the shape of the work clothes with fans were created using a 3D scanner, and an analysis was performed by setting the measured fan air volume to evaluate the thermal sensation and comfort. To verify the analysis model, PIV measurements were performed and the wind speeds at the chin, nose, back of the neck, and back of the head were compared with the analysis results. As a result, when the work clothes with fans model was worn, the skin temperature decreased at the head, neck, chest, and back, and the thermal sensation and comfort of the whole body also decreased. The wind speed at the chin and nose was weaker in the CFD analysis than in the PIV measurement.
