Thermal psychological models of the human body have great
importance with the concept of local sensation and thermal com-fort The thermal sensation and comfort are mainly based on
the local skin and core temperaturesThose models of human
thermoregulation can predict the local skin and core temperatures,
along with heat and moisture transfer between the human body
and environment, hence evaluating the local and overall thermal
sensation and comfortly, and (where applicable) conductively
coupled to a model of the surroundings.The BTCM model's simulated segment skin and core tempera-tures are used to also predict perceived thermal sensation and
comfort, for each segment and for the whole body (e.g. hand
sensation cold or hot,whole-body cold or hot, etc.), using an
embedded set of sensation and comfort models developed by
Zhang The BTCM model has been validated against empirical
physiological responses in transient, non-uniform therma environments
However, the treatment of clothing insulation in the BTCM
model has been insufficient for the purposes of the model, which
include predicting dynamic sensible and evaporative heat transfer
for each body segment under a range of wind and walking conditions This paper describes the new clothing model, compares its
predictions to manikin studies of clothing insulation under wind,
and to human subject tests of human thermal physiology
The original clothing model calculated moisture absorption/
desorption in the clothing using the regain approach This
assumed the moisture content of the clothing to be at equilibrium
with the relative humidity in the air. However, equilibrium with the
environment is often not reached in transient thermal environments The clothing absorption/desorption needs to be
considered as part of the model.
