The assessment of the thermal environment is one main issues in bioclimatic research, and more than 100 simple indices have thus far been developed to facilitate it.However, most these proved be limited applicability, do not portray actual impacts conditions on human beings.Indices derived from heatbalance models (one-or two-node) found offer a better representation environmental impact question ones.Indeed, new generation multi-node for heat balance allow full account taken transfer...
The thermal, evaporative and wicking properties of clothing depend not only on the fabric but also thickness air layers magnitude contact area their variation. aim this study was to accurately determine gap between human body in detail. These parameters were measured for a range typical patterns garments (tight- loose fitting) covering either upper or lower made various types fabrics (knitted woven). method consisted imposing three-dimensional scans nude dressed manikin determining distance...
Human thermoregulation models, particularly the Fiala model, are well accepted for prediction of thermoregulatory responses and assessment clothing building systems with regard to human thermal comfort. However, convective heat transfer coefficients (hc), used calculations, were obtained from measurements a manikin poor body resolution decades ago, they not distinguished between postures. In this study, overall local hc in both standing seated postures evaluated by CFD simulations...
The heat and mass transfer in clothing is affected by the distribution of air gap thickness contact area this, turn, results from interaction between geometrically complex shape human body, garment design, fabric mechanical properties. In this study, typical shirts undershirts were investigated using three-dimensional scanning technique relation to style fit, properties, body regions. This study showed that at upper trunk was unaffected both whereas changed only fit. At lower proportionally...
Thermal sweating manikins are used to analyse the heat and mass transfer phenomena in skin–clothing–environment system. However, limiting factor of present thermal is their inability simulate adequately human behaviour, which has a significant effect on clothing microenvironment. A mathematical model physiology was, therefore, incorporated into system control thermoregulatory responses perception comfort over wide range environmental personal conditions. Thereby, computer provides...
The heat and water vapor transport in clothing results from fabric properties, air layers enclosed the garment environmental conditions. Accumulation of moisture intensifies this because change thermal properties wet fabrics size gap thickness contact area. This paper presents distribution gaps areas relation to various contents typical undershirts confectioned with contrasting affinity moisture. effect undershirt fit, body region, structure fiber type is also discussed. area were determined...
Thermal sensation models, capable of predicting human's perception thermal surroundings, are commonly used to assess given indoor conditions. These models differ in many aspects, such as the number and type input conditions, range conditions which can be applied, complexity equations. Moreover, associated with various scales. In this study, a systematic comparison seven existing has been performed regard exposures including air temperatures, clothing insulation, metabolic rate values after...
Thermal effects, such as cooling power and thermophysiological responses initiated upon application of a personal system, can be assessed with (i) humans, (ii) thermal manikin (iii) human simulator. In order to compare these methods, shirt (mild cooling) an ice vest (strong were measured using participants manikin. Under all conditions, was provided for 45 min, while resting at room temperature 24.6–25.0 °C relative humidity 22–24%. Subsequently, the simulator used under same conditions...
The moisture transfer and absorption properties of fabrics play an important role in the evaluation overall wear comfort textile. location textile influences skin wetness as well skin/textile friction process. In this study, we used X-ray tomography to analyze transplanar in-plane water transport different sock materials when two defined pressures were applied inner side by means adjustable screw. polyamide, polypropylene wool, had very distinct hydrophilic/hydrophobic hygroscopic...
Most standards and devices for determining clothing properties ignore the physiological state of wearer are inadequate to evaluate transient thermal ensembles. This study evaluated burden different types protective environmental conditions using recently developed single-sector thermo-physiological human simulator compared its performance with a cylinder (without control model) an advanced model (with simple model). A simulate dynamic perceptual behavior humans over wide range personal was...
