The Heating and A/C system on a spacecraft must recirculate the air, introduce the needed oxygen, unlink unwanted gases like carbon dioxide, and control humidity levels.
Ever since our kid was little, he has said that he wanted to be an astronaut. He always wanted his room decorated in spaceships and we even had the solar system painted on his ceiling. Once he was in school, he kept this dream alive by applying to space camp in the Summer and studying anything and everything about space travel. Now that he is university he is studying to become an Aerospace Engineer. Although he would still rather go into space, he realizes that designing the equipment and things like space shuttles is just as interesting. He also has a better chance of getting a job in this field, he told us he was surprised about how complex the Heating and A/C system needed to be on these vehicles. But, when he thought about it, this system was responsible for not only maintaining temperature, but ensuring that the tenants had fresh air to breath. It’s not like they can open a window or step outside in space. The Heating and A/C system on a spacecraft must recirculate the air, introduce the needed oxygen, unlink unwanted gases like carbon dioxide, and control humidity levels. This is a absolutely crucial part of the design on a whole, we are extremely proud of how dedicated our kid is to this field of study. He always stuck to it but also realized that he needed a job that would pay well and have more chances than that of an actual astronaut. As an added benefit, he has a better appreciation for how much of a job Heating and A/C systems play in our weekly lives.
