Description

The two-node model of human thermal regulatory response was combined with a transient model of heat and moisture flow through clothing. The combustion provides a means to simulate the dynamic response of the human to the thermal environment and to evaluate the dynamic load the human imposes on the environment. The accumulation of moisture on the skin and in the clothing, the thermal capacitance of the clothing, and the interaction between the clothing and the body’s thermal regulatory responses are included in the simulation. Transient responses typically last 20 to 60 minutes after changes in the environment and activity. During this period, the mix of dry and latent heat flow at the skin can differ significantly from the mix dissipated to the environment. These differences can impact the amount of sweating required and the latent load imposed on the environment.
