Repeated determination of convective and radiative heat transfer coefficients using 32 zones thermal manikin

Repeated determination of convective and radiative heat transfer coefficients using 32 zones thermal manikin

Abstrakt

An average European citizen spends 80 to 90 % of his, hers workday time indoors, in buildings or vehicles [1]. Owing to this fact, importance level of correct building design in means of thermal comfort, air quality, together with low energy demands is high. In addition many independent studies have proven negative influence of improper thermal environment on a human body [e.g. 2, 3]. However such situations can be in future tackled using modern computational methods. To do so there is a need for anatomically detailed heat transfer coefficients that quantify heat flux from a human body. A lot of research has been done in order to investigate heat transfer coefficients in various body postures, wind speeds and wind directions [e.g. 4, 5, 6, 7]. On the other there has not been any emphasis given at the measurement reproducibility. A thermal manikin was involved to determine convective and radiative heat transfer coefficients in sitting and standing posture repeatedly.
