Thermal comfort analysis of electric heating clothing
Aiming at the comfort demand of sedentary young women in low greenhouse,an in-depth research is conducted on the heating areas,heating patterns and fabric combinations of garments.Three kinds of fabrics,cotton,velvet and modal,are selected to form sandwich heating design with carbon fiber heating sheet,and thermal comfort experiment with and without human body are carried out.The experiment results show that the surface temperature of the three kinds of fabrics gradually stabilizes with the increase of heating time,and the low,medium and high grade stabilizes at 30 ℃,35 ℃ and 40 ℃ respectively.The relative humidity of the fabric first increases and then decreases with the increase of temperature,and then gradually stabilizes.The low,medium and high grade remains stable at 30%~37%,27%~32%and 23%~26%respectively.In the medium heating mode and with pure cotton fabric as the interlayer,the heating suit can improve the thermal sensation and thermal comfort of the human body most efficiently.The research results can provide some reference for the selection of fabric and the improvement of heating performance of electric heating clothing.
