载人航天器密封舱以通风换热方式对舱内人员及其设备进行散热,控制舱内温度,利用冷凝干燥组件调节舱内湿度.针对某一处于独立飞行状态下、由返回舱和轨道舱组成的密封舱,采用数值模拟软件I-DEAS对其速度场、温度场以及湿度场进行了稳态数值分析,研究了密封舱内的温度分配和湿度分布,并对密封舱的温湿控制方案的合理性进行了评价.%The temperature of manned spacecraft pressttred cabins is controlled by ventilation heat transfer, and the humidity is controlled by condensation drying component. For an independent flight manned spacecraft pressured cabins consisted of re-entry module and orbital module, a steady numerical simulation on the velocity distribution, temperature distribution and humidity distri-bution is performed by I-DEAS software, and the feasibility of temperature and humidity management is discussed and analyzed.
