Influence of ventilation mode on human thermal sensation and skin temperature in rooms with radiation air conditioning

The difference of human thermal comfort in the room under the two ventilation modes of radiation ceiling plus mixing ventilation and radiation ceiling plus underfloor air distribution is investigated by using the method of subjective questionnaire and experiment, and the effects of ventilation mode on human thermal sensation and skin temperature are analysed. The results show that the differences in local skin temperature under different ventilation modes are inconsistent with those in thermal sensation of corresponding parts. The ventilation mode has a little influence on the overall thermal sensation of the subjects, but has a great influence on the local skin temperature and local thermal sensation.
