An air cooling system provides which type of cooling by blowing cool air over the body inside a suit or vest?

Explanation:
Convective cooling is at work. When the system blows cool air over the body inside the suit, heat is carried away by the moving air from the skin’s surface. This is forced convection, since a blower actively drives the air flow to remove heat. Radiant cooling would involve heat transfer from the body to surrounding surfaces via infrared radiation, which isn’t the mechanism here. Conductive cooling requires direct contact with a cooler solid, and evaporative cooling relies on moisture evaporation from the skin or air; neither is the primary method in this setup.
