A project log for Smart Dew-Point Water Harvester

Harvesting clean drinking water from sunshine.

I'm currently developing the electronics to control the Dew-Point Water Harvester. An area I have identified when experimenting with the basic prototype is that reducing the temperature of the condenser coil far below the dew-point temperature does not automatically equate into an increased rate of water collection. With the additional temperature monitoring of the condenser and a PWM control to the speed (flow rate) of the submersible pump it would be possible to regulate the temperature at the optimum temperature. This will decrease the rate at which coolant is reheated heated and increase the time available to collect dew, consequently more water.
