Thermal Responses on Subjects Wearing Rechargeable Heating Insole in $18^{\circ}C$ Ambient Temperature

For the building energy conservation, the energy authorities recommended that the manager of building should keep the indoor temperature below $18^{\circ}C$ in the public spaces, in the large scale building during heating season. The occupants in the spaces don't feel the thermal comfort because Predicted mean vote(PMV) of the spaces temperature below $18^{\circ}C$ is approximately -1.0(slightly cool). Recently, the companies of wears supply the rechargeable heating insole with the lithium ion battery to the people in the cold environment. This research aim is to present of thermal responses when the occupant wearing the rechargeable heating insole in the spaces temperature below $18^{\circ}C$ through it experiment on the thermal responses of subjects wearing rechargeable heating insole as well as it evaluate on the variation of thermal responses of subjects in the climate chamber. The variations were Thermal sensation vote(TSV) with ASHRAE 7 and 11 scales, Mean skin temperature(MST) with ISO 9886-2004, Sole skin temperature(SST) of the subjects as well as PMV of environmental chamber. The research presents that TSV-7scale, TSV-11scale, MST of the subjects wearing heating insole were not increasing during the experiments. As contrast this, SST of the subjects were $1.6^{\circ}C$ higher than the subjects not wearing heating insole. In conclusion, the rechargeable heating insole with the lithium ion battery influence the SST increasing but it can't influence the whole body thermal response at the $18^{\circ}C$ environment.
