| Outline of Final Research Achievements |
We tried to realize efficient task heating by radiant heating with strong directivity. First, radiation directivity of radiant heating appliances was used to ascertain the radiation directivity. Next, it was confirmed that the directivity can be increased by making the additional reflector longer in the heat radiation direction and using a material with high reflectance. Moreover, by numerical simulation, it is revealed that it is better to have strong directivity of radiation for task heating.
On the other hand, the heat receiving part which can obtain the most thermal comfort was examined by human subject experiment. As a result of the questionnaire survey, it became comfortable for men to warm the lower body and chest and women to warm the lower legs. However, in the evaluation by the stress index based on the heart rate, the most comfortable feeling was obtained by irradiation on the abdomen etc.
