Outline of Final Research Achievements |
A parasol is one of the portable means that can mitigate heat stress in summer. The use situation of parasols was revealed by a questionnaire survey for female college students. To clarify the thermal performance of a parasol, the measurements of environmental parameters under the parasols and a series of subjective experiments using the parasols were carried out in hot summer. Based on the measured data, the universal effective temperature (ETU) for the person using the parasol was calculated, and the thermal effect of the parasol was demonstrated quantitatively. Statistical analysis revealed that the parasols lowered the effective temperatures for whole-body in 1 to 2 degree Celsius and those at the head of parasol users in 4 to 9 degree Celsius, depending on the fabric of parasol. Consequently, the parasols can improve human thermal comfort and reduce the risk of heat illness in hot summer.
