Using the models already developed by CRF for the assessment of the dry thermal comfort in cars (thermal manikin EVA3), it has been define a test methodology to measure the wet thermal comfort. A prototype sensor has been developed and tested on fabrics and seats to measure the thermal parameters needed for seat comfort evaluation. By means a suitable algorithm it is possible to identify the thermal parameters needed for the seat comfort evaluation: the thermal resistance and the water vapour resistance. The preliminary tests demonstrate a good repeatability and sensibility of the device. As this instrument can work without a climate chamber, it could be used in car for road tests and integrated in a manikin for the assessment of both dry and wet thermal comfort.
