Regardless  of  the  vehicle's  application,  the  thermal  comfort  of  the  vehicle's occupants and driver is given increased attention. Maintaining a sense of thermal comfort, whether for  safety,  health  or  occupant  thermal  well-being  reasons,  is  one  of  the  most  important  goals  of heating,  ventilation  and  air  conditioning  (HVAC)  systems.  There  are  a  significant  number  of physical  variables  that  affect  thermal  comfort.
