Abstract

Aiming at the thermal comfort problems brought from anti-riot helmet in high temperature, an study of meas-uring the temperature of head skin based in the anti-riot helmet micro environment is designed, and thermal comfort of the volunteer is evaluated through the skin temperature and the volunteer's own subjective feeling. Results show that the skin temperature of forehead, overhead, cheek and the back of the skull increase by 0.5, 0.5, 0.3 and 0.3 degrees Celsius respectively with initial time under the conditions of (25±0.1) degrees Celsi-us, while the rising temperature are 2.1, 3.4, 2.1 and 2.3 degrees Celsius respectively under the conditions of (35.1±0.2) degrees Celsius. The skin temperature is reduced 0.21 degrees Celsius when a vent is designed on the helmet. The final conclusion is that thermal comfort of the head is not obviously affected by the wearing of anti-riot helmet at normal temperature, while wearing anti-riot helmet under the condition of high tempera-ture can bring serious thermal discomfort to the wearer. What's more, designing several ventilation holes on the helmet can enhance the overall thermal comfort of the head to some extent.
