Abstract
The current concept of Crew Quarters on board of the International Space Station has several issues according to the crew member’s feedback. Major issues concern noise levels, the accumulation of CO2 and the quality of the air distribution. Our study targets the airflow distribution, to diagnose this issue, we realise a series of numerical simulations (CFD) based on a real scale replica of the Crew Quarters. Simulations were set with a zero-gravity mode and with the theoretical air parameters inside the SSI. The geometry includes a thermal manikin having the neutral posture of a body in the absence of gravity. Numerical simulations were run for the three different air flow rates provided by the current ventilation system. Results have shown that the air distribution inside the Crew Quarter is insufficient for low airflow rates but becomes acceptable for the higher airflow rate, however the higher airflow rate can potentially produce draught discomfort.
Highlights
This paper presents a study of the air quality within the International Space Station and more inside the private cabins of crew members, called Crew Quarters
A good rest for the crew members is essential, because firstly there are only six members permanently on the International Space Station, and secondly, the tasks performed by crew members require increased concentration, so they must be in good health and efficient
This study helps us to understand the importance of considering the real velocity profile instead of a uniform velocity profile
Summary
This paper presents a study of the air quality within the International Space Station and more inside the private cabins of crew members, called Crew Quarters. The current concept of Crew Quarters on board of the International Space Station has several issues according to the crew member’s feedback. Major issues concern noises levels, the accumulation of CO2 and the quality of the air distribution [1].Like all human beings, crew members need rest. A good rest for the crew members is essential, because firstly there are only six members permanently on the International Space Station, and secondly, the tasks performed by crew members require increased concentration, so they must be in good health and efficient. Thermal comfort and air quality must be optimal, sources of noise must be negligible and the overall system must be energy efficient. The air distribution system and sound insulation must be efficient, effective and compact
