How do air-conditioned suits cool down?

In fact, the human body has a "physiological cooler function", in which the brain processes information from sensors that detect heat, and the human body produces sweat based on the amount of cooling required at that time. When enough fresh air flows parallel to the body, sweat can evaporate completely, taking away the heat. But if there is no airflow, no matter how much water you drink, you will only waste sweat and will not be able to cool down the body.

Therefore, according to the characteristics of the human body's self-regulating temperature, the fan of the air-conditioned suit introduces flowing air to speed up the evaporation of sweat, and blows the hot air out of the neckline and cuffs to form a circulating air layer to achieve cooling. Air-conditioned clothing solves the problem that heat is difficult to dissipate from the body surface when sweating, and keeps the body in a comfortable range.
