Independent temperature and humidity control system and implementation method of airtight cabin of space vehicle

Abstract

The invention belongs to the technical field of thermal control of an environment of a sealed cabin of a space aircraft, and relates to an independent temperature and humidity control system for a sealed cabin of a space aircraft and an implementation method. By means of the design of the independent air temperature and humidity control system structure and the implementation method, decoupling control on the temperature and the humidity of air in the sealed cabin of the space aircraft is achieved, the defect that control requirements of double targets of the temperature and the humidity of the air are difficult to meet by means of an integrated temperature and humidity control system is overcome, and the detailed requirement for controlling the temperature and the humidity of the sealed cabin of a future space aircraft is met.

Description

technical field [0001] The invention relates to an independent temperature and humidity control system and an implementation method of a space vehicle airtight cabin, belonging to the technical field of space vehicle environmental thermal control Background technique [0002] With the development of human space technology, in recent years, manned space technology such as low-Earth orbit manned spacecraft and manned moon landing spacecraft has achieved rapid development in many countries, and manned missions have also shown a long-term development trend. As the passenger carrier of manned spacecraft and manned moon landing spacecraft, the airtight cabin is responsible for the important task of providing suitable temperature and humidity environment for the astronauts in the cabin. The research on the temperature and humidity control technology of the airtight cabin is very important to ensure the life safety of astronauts, The normal work of the equipment load in the cabin an...

Problems solved by technology

However, for my country's future long-term resident space missions, it is not only necessary to ensure the long-term comfort of the astronauts, but also to consider the influence of air temperature and humidity on the growth of microorganisms. There is strong coupling, and it is difficult to meet the dual control index requirements of air temperature and humidity in the sealed cabin, which will have a certain impact on the successful completion of my country's manned space missions
