前言 对于在化学和生物因素威胁下在高温中进行训练的直升机飞行员来说,个体微小气候降温能缓解其热紧张。本研究在模拟沙漠气候条件下测试4人微小气候液冷降温系统设计原型维持安全及舒适的生理状况的能力。方法 在49℃,15％相对湿度环境下。对26位身着防化飞行服的志愿受试者在休息状态下进行4h测试。测试对象身着一种贴身长袖衬衫,在其臂和躯干部的内表面缝有60m长,3/8in(7.62/20.32cm)的细管,经冷却装置向管内灌入22℃、流速为0.5
Introduction For helicopter pilots trained at high temperatures under the threat of chemical and biological agents, individual microclimate cooling can relieve their heat stress. This study tested the ability of 4-person microclimatic liquid cooling system to simulate desert climates to maintain a safe and comfortable physiological condition. Methods at 49 ℃, 15% relative humidity environment. Twenty-six volunteers in chemical-resistant flight suits were tested for 4h at rest. The test subject wore a personal long-sleeved shirt and sewed a thin tube of 60 m long and 3/8 in. (7.62 / 20.32 cm) on the inner surface of the arm and trunk. The tube was filled with 22C at a cooling rate of 0.5
