This paper introduces the sealing of umbilical tower in manned space launch site and the working process of air-conditioning system in sealed room. Based on the thermodynamic modeling of sealed environment of umbilical tower, the calculation method of filling amount is studied, and the countermeasures of sub-period calculation are proposed. Several mission applications were introduced and the accuracy analysis.
