Book Synopsis Environmental Heat Transfer to a Microclimate Cooling System During Heat Exposure by : M. Katherine Canine
Download or read book Environmental Heat Transfer to a Microclimate Cooling System During Heat Exposure written by M. Katherine Canine and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat transfer from the environment (Q(env)) to a water-based microclimate cooling system (MCS), operated at four temperatures of water (T(w)), Was measured utilizing a rubber manikin outfitted in coveralls and chemical protective clothing. Q(env) increased in direct proportion to the difference in T(w) and ambient temperature (T(a)). Good linear models were found for predicting Q(env) when T(a) or temperature between clothing layers and T(w) are known. These models can be used in future physiological tests to apportion heat transfer between the environment and the body. Q(env) was substantial, greater than 100 w at the lowest temperature of water, even when insulated from the environment. Because many MCSs have limited cooling capacities, it is important to reduce Q(env) Thus, it is advantageous to wear insulating garments in hot environments when microclimate cooling is used.
Book Synopsis A Review of Microclimate Cooling Systems in the Chemical, Biological, Radiological Environment by : T. Derion
Download or read book A Review of Microclimate Cooling Systems in the Chemical, Biological, Radiological Environment written by T. Derion and published by . This book was released on 1993 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soldiers may work in hot environments and under conditions posing a biological, chemical, or nuclear threat. Chemical protective overgarments are worn to prevent contact with toxins; however, they prevent dissipation of body heat. This review addresses the effectiveness of microclimate cooling systems in alleviating thermal strain in personnel encapsulated in protective overgarments during exertion in the heat. Air, liquid, and passive ice cooling systems are primarily reviewed, but other methodologies are also discussed. Air cooling can increase tolerance time fourfold, but high ambient temperature air cooling may be dangerous. Liquid cooling is effective in reducing heat strain at light to moderate work loads and is beneficial when applied to the thighs during lower- body exercise. Overcooling and discomfort can occur with a liquid-cooled system due to cutaneous vasoconstriction. Liquid-cooled systems are heavy, require excessive maintenance, and tube compression can result in interrupted coolant flow. Air cooling is inefficient compared to liquid cooling because of air's lower specific heat. Ice cooling may only be suitable for short-term work and is generally less effective than either air or liquid cooling although the wearer can move about untethered. The best cooling system design approach may he indicated by consideration of the unique cooling needs of personnel performing specific tasks in various environments.

Book Synopsis Thermal and Moisture Transport in Fibrous Materials by : Textile Institute (Manchester, England)
Download or read book Thermal and Moisture Transport in Fibrous Materials written by Textile Institute (Manchester, England) and published by Woodhead Publishing. This book was released on 2006-10-30 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transfer of heat and moisture through textiles is vital to the manufacture and design of clothing, technical and protective textiles. Continued advances in textile processing technology, the growth of manufactured nonwovens and the application of nanotechnology have resulted in a wealth of research in order to characterise the behaviour of these materials. Thermal and moisture transport in fibrous materials provides a comprehensive guide of the technological developments and scientific understanding in this area. The first section summarises the structure, geometry and stereology of fibrous materials. The fundamentals of wetting and its dynamics are also discussed. Part two analyses thermal and liquid interactions in textiles and offers insights into the thermodynamic behaviour of moisture as well as heat and moisture coupling. The book concludes with chapters on the human thermoregulatory system, interfacing between fibrous materials and the human body and innovative computer modelling simulations. Thermal and moisture transport in fibrous materials is an essential reference for all those involved in the textile industry, especially those concerned with the design and manufacture of technical textiles and protective clothing.

Book Synopsis Effects of Discrete Skin Cooling on Body Temperature and Sweat Production During Moderate Heat Stress by : Thomas G. Byrne
Download or read book Effects of Discrete Skin Cooling on Body Temperature and Sweat Production During Moderate Heat Stress written by Thomas G. Byrne and published by . This book was released on 1968 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiological responses to moderate heat stress were studied in a heat chamber for periods of 2 hours. Five conditions were established (two control series and three cooling series). Measured variables included heart rate, sweat produced, and rectal temperature. Thirty-eight experiments were done, involving eight subjects. The data were subjected to both conventional statistical analysis and computer techniques. (Author).

Book Synopsis Simulation of Human Thermoregulatory Responses to Micro-Cooling in Hot Environments by :
Download or read book Simulation of Human Thermoregulatory Responses to Micro-Cooling in Hot Environments written by and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Situations occur where individual cooling is desirable to reduce heat injury and improve productivity. Simulation of human responses while wearing possible micro-cooling systems can assist planning and soften their development. A thermo-physiological model modified for micro-cooling was developed to predict body temperatures, other physiological parameters, and discomfort in hot environments. The micro-cooling simulated was: (1) uniform whole body cooling under clothing, (2) cooling of upper torso with a water cooled vest under clothing, and (3) cooling of upper torso with an air cooled vest under clothing. The modeling suggests upper torso cooling above 200 watts can cause vasoconstriction reducing the effectiveness of greater cooling.
