Hi everyone
I am currently designing a system to purify water as part of my engineering course.
My team had the idea to distil the water. This could easily be done as the place where it would be used receives a lot of sunlight (outback Australia). However I started think for ways to improve our system and I quickly realized the lowering the pressure would lower the boiling point.
Now If that pressure is low enough to get the boiling point below the dew point of the outside air. Then we could insulate the box and try to condense water with the box because its temperature would not rise above the boiling point.
The biggest problem is: Does the condenser need to have a lower temperature than the boiler side? Or would it be enough to blow hot air (which we get from the outside) over the boiler side?
It the latter would work then we would have a great way to collect at least some extra water
Many thank in advance
