Abstract

Fresh air temperature supplied by an Environmental Control System (ECS) in a manned spacecraft is generally at 16 ,which is a low air temperature if it is blow to the astronauts directly. In order to improve the thermal comfort, the supplied air temperature should be increased by reducing the amount of supplied air. However, the sleeping area in manned spacecraft should have a feature of warm and high flow velocity. Since the amount of CO2 will be easy to accumulate if the air velocity is not high enough. Yet high flow velocity and big amount of fresh air are easily to generate surface uncomfortable. This characteristic of sleeping area in manned spacecraft makes the requirement to optimize a new air-terminal system of sleeping area in manned spacecraft. This kind of new air-terminal system which should have some excellent properties, which can be easy to diffuse and ensure thermal comfort. This paper presents a kind of new air-terminal system of sleeping area in manned spacecraft which has a non-rotating working parts. The new air-terminal system ejects the cold fresh air which is enclosed by the warm return air that comes from the cabin. In this way, we can not only enhance the supply air temperature to ensure comfort, but also increase the amount of air flow to avoid the accumulation of CO2.To observe the performance of this new air-terminal system, this paper carries out the simulation investigation of the new air-terminal system of sleeping Area in manned spacecraft.
