Active Cooling Systems Integrated into Clothing
topic
Active cooling systems integrated into structural firefighting clothing under development include thermoelectric cooling vests using Peltier elements powered by compressed air from SCBA systems, liquid cooling garments circulating chilled water through microtube networks, and vortex tube cooling systems deriving cold air from compressed air systems that provide cooling air to garment microchannels beneath the turnout clothing, with each approach facing the challenge of providing meaningful physiological cooling within the weight and bulk constraints of firefighting clothing systems.
Role
Addresses the fundamental limitation of passive clothing design in managing firefighter heat stress by providing active heat removal from the body that increases safe working time beyond what optimised passive clothing can achieve alone, with active cooling being the technology direction most likely to substantially improve physiological safety during prolonged high-intensity firefighting operations where passive clothing optimisation has reached practical limits without compromising thermal protection.
