Abstract: The direct blowing of cold air in air conditioning often causes discomfort to human body, and then causes cold and other diseases. Therefore, the research on comfortable wind feeling of air conditioning has positive practical significance. Firstly, the paper analyzes and summarizes the existing schemes to prevent the direct blowing of cold air from air conditioning, and expounds its technical characteristics. Based on the technical discussion and the author's technical level, a mass-produced split wall-mounted air conditioner was transformed, mainly based on the change of the shape and size of the air deflector, and the flow field simulation analysis of the change scheme was analyzed by using FLUENT, which preliminarily verified that the new scheme can achieve the effect of comfortable wind feeling in cooling mode and heating mode.
