摘　　要：通过夏季室外穿着试验,研究蓄冷式简便液冷服采用不同蓄冷物时循环水温度随时间的变化情况,发现随着冰质量的增加有效冷却时间延长,但循环水降温剧烈,造成过冷;吸水冰晶蓄冷能够显著减缓温度变化,但有效冷却时间较短。试验中尝试使用双层冰盒,使冰的能量释放得到减缓,液冷服的降温效果和有效冷却时间均得到改善。特别是冰盒间隙中注入质量分数为10%、理论相变温度为25℃的相变微胶囊乳状液时,改善程度相对较显著,最低温度为22.9℃,有效冷却时间达110min。The change of the circulating water temperature of energy storage simple Liquid Cooling Garment with the time has been studied by outdoor wearing test in summer,with different energy storage materials.As the ice increasing,the effective cooling time increases,but too cold to make human body comfortable.Ice crystals could slow the change of temperature observably,however,the effective cooling time decreases.In the test,the double-deck energy storage structures have been used to slow the thawing of ice,with the result,cooling effect improved indeed;especially,the lowest temperature is 22.9 ℃,and the effective cooling lasts 110 min,when phase change microcapsules emulsion,mass concentration 10%,theoretic phase change temperature 25 ℃,is injected into the gap.
