2. 1. Comfort Climate Evaluation with Thermal Manikin Methods and Computer Simulation Models

   Author : Håkan O Nilsson; KTH; []
   Keywords : thermal climate assessment; thermal environment; office environment; cabin; climate; CFD; thermal manikin; comfort zone diagram;

   Abstract : Increasing concern about energy consumption and thesimultaneous need for an acceptable thermal environment makesit necessary to estimate in advance what effect differentthermal factors will have on the occupants. Temperaturemeasurements alone do not account for all climate effects onthe human body and especially not for local effects ofconvection and radiation. READ MORE

5. 3. Clothing Evaporative Resistance: Its Measurements and Application in Prediction of Heat Strain

   Author : Faming Wang; Ergonomi och aerosolteknologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal manikin; clothing ensemble; evaporative resistance; localised evaporative resistance; thermophysiological response; heat stress; heat strain; the Predicted Heat Strain PHS model;

   Abstract : Clothing evaporative resistance is one of the most important inputs for both the modelling and for standards dealing with thermal comfort and heat stress. It might be determined on guarded hotplates, on sweating manikins or even on human subjects. READ MORE

6. 4. Evaluation of thermal comfort of head gear : a method to measure heat transfer characteristics

   Author : Xiaoxiong Liu; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

   Abstract : This study was carried out within the research project "Thermal properties of protective helmets - improvement, validation and standardization of a measurement method" which was a continuation of a research project being carried out since 1992 at the Division of Industrial Ergonomics, Department of Human Work Sciences, Luleå University of Technology, Sweden, with co-operation of the Department of Ergonomics, National Institute for Working, Life (NIWL), Solna, Sweden. A method was developed for measuring the evaporative heat transfer properties of helmets, based on the results of a thorough literature survey. READ MORE

7. 5. Protection against cold in prehospital trauma care

   Author : Otto Henriksson; Ulf Björnstig; Tore Vikström; Peter Naredi; Hannu Rintamäki; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hypothermia; prehospital trauma care; emergency medical services; passive warming; thermal insulation; heat loss; body temperature regulation; kirurgi; Surgery;

   Abstract : Background: Protection against cold is vitally important in prehospital trauma care to reduce heat loss and prevent body core cooling. Objectives: Evaluate the effect on cold stress and thermoregulation in volunteer subjects byutilising additional insulation on a spineboard (I). READ MORE
