Cooling system for improving thermal comfort of enclosed type clothing

为了保证穿着封闭式服装的人的安全工作，人体的冷却是必不可少的。为保护负责温度调节和动作判断的头部，设计了轻巧紧凑的水冷系统服装。通过保温试验和试验对象对颈布型和头罩型水冷式服装的冷却性能进行了评价。通过冷却颈部和头部，热感和潮湿感显著改善。应力指标的下降表明穿水冷衣服降低了热应力。为便携式水冷衣的实际应用收集了基础数据。

Cooling of human body is indispensable to ensure the safety work of wearer with enclosed type clothing. Lightweight and compact clothes with water cooled system were designed for protecting human head that takes charge of temperature regulation and action judgment. Cooling capability of prototype model of water cooled clothes of neck-cloth type and head-covered type was evaluated by thermal insulation test and test subjects. Thermal and humid sensations were significantly improved by cooling neck and head. The decrease in stress indicator suggested a lowering of thermal stress by wearing water cooled clothes. Fundamental data were assembled for practical application of portable type water cooled clothes.
