舱室充气加压时间的计算

Time Calculation on Air Charging into Cabin

船上有些舱室需要充气加压,客户需要了解充气加压的时间以及保压时间等参数。本文分析了舱室充气加压过程中室内气体状态变化情况,给出了充气时间的计算公式,并给出了保压过程中室内气压因温度下降而引起的压降值的估算方法。

Some cabins on board need to be charged with air, customers need to know the time of air charging or pressure maintaining. This article analyzes the state changes of the air charged into a cabin and gives the formula to calculate the time of air charging and also the method to estimate the pressure reduction caused by the temperature drop in pressure maintaining process.
