Effectiveness of a Prototype Microclimate Cooling System for Use with Chemical Protective Clothing

Abstract

Facility conducted laboratory evaluations of a prototype, portable microclimate cooling system (MCS) designed for use with chemical protective clothing. The MCS circulates chilled liquid through a torso vest. A backpack unit contains an ice pack; a pump and motor assembly and a rechargeable battery are mounted on a chest or waist strap. Total weight of the MCS is 9.3 kg (20.4 lbs). To examine the effectiveness of the system in reducing heat strain, seven male test subjects participated in a laboratory heat stress evaluation. To determine the cooling power and efficiency of the MCS, thermal manikin testing was conducted.
