摘　　要：分析推导出避难硐室内湿度与压风供气量的计算关系式,并通过试验验证了该公式的适用性。通过试验模拟50人的散湿率,以及不同压风供气量情况下硐室内湿度,得出压风量为300 m^3/h时可将避难硐室内湿度控制在70%以下,而且在相同供风量下,硐室内初始湿度越高,除湿效果越好。Analyzed and deduced refuge chamber indoor humidity and air pressure, gas volume calculations relationship, and verified the test 50 people scattered wet rate, without draw pressure air volume 300 m^3/h refuge applicability of the formula by experiment. Through simulation ventilation and gas supply situation cave indoor humidity, the chamber indoor humidity can be controlled at 70% or less, and in the same amount of ventilation, indoor cave initial higher the humidity, the better dehumidification.
