Study on Thermal Environment and Thermal Comfort of Passenger Compartment in Winter Night

Abstract:

The thermal environment inhomogeneity of the cabin in winter night was studied by the method of combining experiment and numerical simulation. The temperature and velocity inhomogeneity of the cabin in different air supply modes were obtained. Then, based on Stolwijk human thermal regulation model, the Berkeley thermal comfort evaluation model is adopted to simulate the thermal comfort state of passengers, and the thermal comfort under two air supply modes was analyzed. Finally, the actual air supply condition, the isothermal air supply condition based on the same enthalpy and the uniform thermal environment condition based on the equivalent flow in front of the driver were compared and analyzed. It is found that the occupant is more likely to be in an uncomfortable state in an uneven thermal environment.
