Available in PDF, EPUB and Kindle. Book excerpt: Three commercially available microclimate cooling systems were evaluated for their ability to reduce heat stress in men exercising in a hot environment while wearing high insulative, low permeability clothing. Five male volunteers performed three 180-min experiments (three repeats of 10 min rest, 50 min walking at 440 watts) in an environment of 38 C dry bulb (Tdb), 12 C dew point (Tdp). The cooling systems were: ILC Dover Model 19 Coolvest (ILC), mean inlet temperature 5.0 C; 2) LSSI Coolhead (LSSI), mean inlet temperature 14.5 C; and 3) Thermacor Cooling Vest (THERM), mean inlet temperature 28.3 C. Endurance time (ET), heart rate (HR), rectal temperature (Tre), mean skin temperature (Tsk), sweating rate (SR), rated perceived exertion (RPE), and thermal sensation (TS) were measured. The subjects self terminated on all LSSI tests because of headaches. Statistical analyses were performed on data collected at 60 min to have values on all subjects. Keywords: Reprints, Heat stress(Physiology), Exercise(Physiology).

Available in PDF, EPUB and Kindle. Book excerpt: Laboratory and field evaluations were conducted to examine four ice- based portable cooling systems and one thermoelectric vehicle mounted cooling system, to assess and compare their performance under laboratory and field conditions. There were three battery-operated circulating liquid cooling garments, a passive frozen gel pack vest, and a thermoelectric circulating liquid cooling garment. The thermal manikin tests were conducted in a 35 C (95 F), 5% relative humidity, environment with the mannequins surface temperature at 35 C (95 F). The manikin was dressed in the Battle Dress Overgarment (BDO) chemical ensemble in all of the tests. Army and Air Force personnel took part in five field evaluations. These personnel provided information related to compatibility, mobility, ease of operation and donning and doffing.

This book was released on 1988 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Navy Clothing and Textile Research Facility (NCTRF) conducted a laboratory evaluation to compare two commercially available, portable, liquid microclimate cooling systems for their effectiveness in reducing heat stress and for their operational characteristics. The systems were the Model 1905 Cool Vest manufactured by ILC Dover, Inc. (ILC), and the Cool Head manufactured by Life Support Systems, Inc. (LSSI). The two systems were evaluated on nine test subjects wearing the Navy utility uniform and performing light-to-moderate exercise for 3 hours in an environment of 43 C dry bulb, 29 C dew point (WBGT 36 C). Compared with a control test with no cooling, use of either cooling system enabled subjects to complete the 3-hour heat exposures. Rectal temperature responses were the same when either cooling system was used. Heart rates were slightly lower with the ILC Dover system compared to the LSSI system. The ILC systems experienced fewer failures, and were easier to operate than the LSSI systems. The ILC system is also lighter, less bulky, and much less expensive than the LSSI system. Based on their similarity in reducing heat stress, and the ILC Dover system's profile, reliability and lower cost, the ILC Dover Model 1905 Cool Vest system is recommended over the Cool Head for Navy use. This report describes the two cooling systems and the results of the heat stress evaluation. (aw).

This book was released on 2005 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Professionals in dire need of body cooling, namely the First Responder community, can currently choose from an extensive variety of commercially available microclimate cooling products incorporating a wide range of technologies. Since not all products will meet the requirements of all users, it is important to understand the characteristics of the systems that are available, prior to making a selection. Currently, no standards exist for validating microclimate cooling systems, so users are forced to rely on vendor claims when purchasing equipment. The goals of this project include searching the commercial market for all current microclimate cooling products, and evaluating a representative cross-section of products for their thermal performance. The information gathered was compiled in a database and a report, and can be provided to Emergency Responders to aid in their equipment-purchasing process.

Book excerpt: Abstract : Extreme temperatures, both hot and cold, can severely restrict the ability of aircrew and support personnel to accomplish their missions. Under emergency conditions of bail-out, ejection and ditching of fixed or rotary-wing aircraft on land or in water, the survival rate of aircrew and passengers is also affected by the intensity of thermal stress experienced and the duration of exposure to the thermal stress. This has all recently been borne out by the experience of intense air operations in the Gulf War. This symposium reviewed the operational conditions experienced under extreme hot and cold weather. The papers presented at this Symposium highlighted recent advances in thermal physiology, clothing sciences, personal flying equipment, and microclimate cooling. Emphasis was placed on the potential applications of these advances in situations where thermal stress, or the expectation of thermal stress, may confound the efficient achievement of mission objectives
