Forced Ventilation of Protective Garments for Hot Industries

Abstract

The performance of a battery powered, forced air distribution system for ventilation under protective clothing (torso body armor) was evaluated on a sweating thermal manikin in a 35 deg C and 50% RH environment. The ventilation system, delivering 9 L dot s(-1) of ambient air increased the heat loss from the manikin by 45 W. Measurements made on the manikin indicated that the ventilation decreased the dry thermal resistance and the vapor resistance of the clothing system by 17 and 20% respectively.
