摘要：

为评价低温、风速与风向环境中睡袋的实际使用过程保暖作用,改善睡袋使用者的舒适度,开展睡袋保暖性能试验。通过低温雨雪冰冻耦合环境舱和牛顿暖体假人系统评估木乃伊式睡袋和信封式睡袋的热阻,测量2种睡袋在变化的环境温度(-20、-15、-10和-5 ℃)、风速(1、2、3、5和7 m/s)和风向(沿头部、腰部和脚部方向)下的热阻参数以及睡袋内部空气层温度,研究单一低温无风环境和复合低温有风环境对睡袋热阻的影响。结果表明:单一低温无风环境中,木乃伊睡袋热阻值变化比信封睡袋稳定,木乃伊睡袋的保暖性更好;在复合低温有风环境中,增大环境风速会降低空气层热阻;当风速为7 m/s时,空气层热阻下降50%;沿头部方向吹风对睡袋热阻值影响最大,木乃伊睡袋总热阻下降42.8%,信封睡袋总热阻下降50.1%,沿脚部方向吹风对睡袋热阻值影响最小,木乃伊睡袋总热阻下降23.1%,信封睡袋总热阻下降29.3%;沿头部风速为7 m/s时,木乃伊睡袋和信封睡袋脚部空气层温度降至最低分别为21.83和26.54 ℃。

Abstract:

To evaluate the insulation performance of sleeping bags during actual use in various low-temperatures, wind speeds and wind directions, and to improve the comfort of sleeping bag users, an experimental study on the thermal insulation performance of sleeping bags was conducted. The thermal insulation performance of mummy-style sleeping bags and envelope-style sleeping bags was evaluated using a low-temperature coupled environment chamber and "Newton" thermal manikin system. Thermal resistance parameters of the two types of sleeping bags under varying environmental temperatures (-20, -15, -10, and -5 ℃), wind speeds (1, 2, 3, 5, and 7 m/s), and wind directions (along the head, waist, and foot directions) were measured. The effects of a single low-temperature windless environment and a combined low-temperature windy environment on the thermal insulation performance of sleeping bags were studied. The experimental results show that in a single low-temperature windless environment, the thermal resistance value of the mummy sleeping bag changed more stably than that of the envelope sleeping bag, and the mummy sleeping bag has better thermal insulation performance. In a combined low-temperature windy environment, increasing the wind speed would reduce the thermal resistance of the air layer; and when the wind speed was 7 m/s, the thermal resistance of the air layer decreased by 50%. Wind direction along the head direction has the greatest impact on thermal resistance, with the total thermal resistance of the mummy sleeping bag decreasing by 42.8% and that of the envelope sleeping bag decreasing by 50.1%. Wind direction along the foot direction had the least impact on the thermal resistance value of the sleeping bag, with the total thermal resistance of the mummy sleeping bag decreasing by 23.1% and that of the envelope sleeping bag decreasing by 29.3%.When the wind speed along the head was 7 m/s, the air layer temperature at the feet of the mummy sleeping bag and the envelope sleeping bag dropped to the lowest, which were 21.83 and 26.54 ℃, respectively.

Key words: low-temperature composite environment, sleeping bag, thermal insulation performance, thermal manikin, wind speed and direction
