摘要:
针对地下矿山作业地点高温高湿问题，提出应用个体御热装备的解决方案。研发了两款采用相变材料的个体御热装备，采用5类主观评价量表对测试人员的热舒适性、触觉舒适性、服装舒适性、织物手感和可用性进行性能评价。结果表明：①两款御热装备都得到测试人员较好的热舒适性评价，但随着时间推移，受人体汗液蒸发影响，两款御热装备都变得较为潮湿，在除湿性能上仍有待提高；②在测试末段，横插式御热装备在可用性指标上得到较好评价，而竖插式御热装备仅得到略微可用的评价，测试人员负面感受来自相变材料的融化下坠感；③整体来看，测试人员更偏向相变材料采用横插式的御热装备，说明对背心式御热装备的优化研究取得了良好效果。

Abstract:
In response to the high temperature and high humidity conditions in underground mining operations,a solution involving the use of inpidual thermal protection equipment is proposed.2 types of inpidual thermal protection equipment utilizing phase change materials have been developed,and a subjective evaluation scale consisting of 5 categories has been used to assess the performance of the thermal comfort,tactile comfort,garment comfort,fabric feel,and usability for the test subjects.The results indicate:①Both types of thermal protection equipment received favorable ratings for thermal comfort from the test subjects,but they became relatively humid over time due to the evapo-ration of bodily sweat,indicating the need for improvement in dehumidification performance;②Towards the end of the testing period,the horizontal-ion thermal protection equipment received a positive assessment for usability,while the vertical-ion thermal protection equipment only received a slightly usable evaluation,with test subjects expressing negative feelings about the sagging sensation caused by the phase change materials melting;③Overall,test subjects showed a preference for the thermal protection equipment with phase change materials utilizing horizontal ion,indicating that the optimization research for the vest-style thermal protection equipment has yielded positive results.
