I am trying to build a dehumidifier for collecting water from air. The goal of this project is to produce at least 50ml of water in 8 hours under extreme and varying conditions, using < 10A of current and 12 V of DC power that is extremely durable.
The extreme conditions I speak of would be -60 degrees and 10% humidity, however I will really take what I can get (as I realise this may be quite a stretch).
So far I have got the following materials:158W Peltier ElementNoctua NH4-D14Arctic Silver Thermal Compound
Generic Lab Power Supply
I am looking for:
Solid State Relay for DC rated for 20A and 15V.
Putting this altogether and running it at 12V makes the surface of the Peltier go to -6 degrees. It quickly collects condensation however before it can run off into the collection vessel it freezes, even if it is hung upside down or sideways. So at the moment I am really looking for a way to prevent my water from freezing before it runs off.
Woud like to hear your thoughts.
