Human thermal comfort is the state of mind which expresses environmental satisfaction according to the ASHRAE 55 standard. Achieving thermal comfort for most occupants of buildings or other enclosures is a goal of HVAC designers. Indoor air quality, although not part of thermal comfort, is a major concern for HVAC designers.
In automotive cabins,the PCS concept can be used to solve fundamental thermal system problems occurring. Historically, the human body has been treated as a uniform cylindrical shape in thermal comfort studies. Extensive laboratory testing on human subjects, conducted by CBE research specialist Hui Zhang, revealed that overall,

The PMV equation for thermal comfort is a stationary model. This is an empirical equation for predicting the mean score on a thermal comfort category ordinal scale for a population. The equation uses a steady-state heat balance for the human body and postulates a relationship between the deviation from minimum load on the heat balance
As a result, the resulting membranes exhibit excellent hybrid active-passive cooling performance with an ultra-high in-plane thermal conductivity of 17.9 w m -1 k -1 and an in-plane thermal conductivity of 0.29 w m -1 k -1 and high vapor permeabilityof water (wvt) of 11.6 kg m -2 day -1 and excellent water repellency
