Abstract:

Aloft cleaners often face severe cold weather conditions. In order to improve the thermal performance of aloft cleaning clothing, an aloft cleaning working suit based on electrical heating was designed and developed. Aloft working conditions with (5±0.5) ℃ temperature and (60±5) % relative humidity were simulated. The skin temperature and activity comfort of the electrically heated aloft cleaning working suit were measured and evaluated through human trials. The results show that the average skin temperature of human body could be maintained better by wearing electrically heating aloft cleaning working suit, and the longer the time the more significant the thermal insulation effect was. Heating plate placed on the back could effectively improve the skin temperature of the trunk without affecting the subjective thermal comfort of the back. Local insert design and blind lap could improve the freedom of movement of clothing.

Key words: electrical heating clothing, aloft cleaning working suit, structure design, comfort evaluation, graphene heating pad
