摘要
针对救生舱在外界持续高温辐射影响下,研究了救生舱内避险人员体感温度的控制,并通过试验验证初始设计计算满足使用要求。采用热平衡的方法,构建了救生舱内各热源的数学模型,在保证体感温度小于35℃的前提下,以蓄冰耗损最小为目标,建立了救生舱内温度热平衡模型,完成了救生舱内平衡温度预估。试验结果表明:在持续106 h高温辐射情况下,救生舱内温度低于30℃,湿度低于75%,经计算人体体感温度低于30%,满足使用要求。
Based on the conditions of the constant high temperature of the rescue chamber, the human body sensing temperature control in rescue chamber is researched and it is testified that the initial designed calculation can meet the requirements of the use. The thermal equilibrium is applied to construct the mathematic model of each heat source in rescue chamber. Under the conditions of ensuring body sensing temperature under 35 ℃ and regarding the least ice emerge conservation as the aim, the temperature equilibrium model has been established and the prediction of thermal equilibrium has been achieved. The experiment shows that, under 106 hours of constant high temperature radiation and temperature and humidity lower than 30℃ and 75% respectively, it is calculated that human body sensing temperature is lower than 30% and can meet the requlrements.
