Originální abstrakt

Personal vehicles undergo rapid development in every imaginable way. However, a concept of managing a cabin thermal environment remains unchanged for decades. The only major improvement has been an automatic HVAC controller with one user’s input - temperature. In this case, the temperature is often deceiving because of thermally asymmetric and dynamic nature of the cabins. As a result, the effects of convection and radiation on passengers are not captured in detail, what also reduces the ability to meet thermal comfort expectations. Advanced methodologies are available to assess the cabin environment in a fine resolution (e.g. ISO 14-505:2007), but these are used solely in laboratory conditions. The novel idea of this work is to implement equivalent temperature sensors into a vehicular cabin. Spatial distribution of the sensors is expected to provide detailed information about the local environment. Next, three different cases were examined in a climate chamber. The focus of the work is to compare results given by the implemented system and a thermal manikin Newton. Finally, the results were compared and a good match of equivalent temperatures was found.
