I am trying to make an DIY dehumidifier. The goal is to lower the humidity
of my room during the summer months (humidity is around 70% at 25C) to
less than 50, preferrable 30%.
I have the following setup in mind:
To achieve condensation I want to use a peltier that will lower the temperature of an radiator.
The condensed water will be gathered in a (plastic) box. This water will then be used to cool the
hot side of the peltier, using a water block and a waterpump that was left over after using watercooling
on my PC.
The image depicts an simple graphic of the setup.
However, I have the following questions to be answered:
- How cold (relative to the ambient temperature) would the cold-side radiator have to be to get optimal condensation
- How much watts of cooling power would the peltier need in order to achieve the needed temperature difference
- If i lower the cold side temperature with 20C, how much heat would be generated on the hot side? (my gues: 20C,
but im no genius ;) )
Thanks in advance!
