Re: combating condensation in van dwelling

[j_pigden]

The problem with all those type of vents is heat-loss. Either the outside air brought in is cold or the outside is cold and the moist air inside condenses. You almost need a dedicated place where condensation CAN occur and you have a drain or a tank to deal with the water there, sort of a natural dehumidifier. I’m thinking a heat transfer plate to use the cold outside air to draw the moisture out of the inside air. Unfortunately, I can’t work out a simple way to keep the heat inside but lower the humidity. The obvious solution is an humidistat controlling an insulated cover on the plate dehumidifier. The inside air only gets to the cold plate when the indoor humidity gets too high. This solution starts to get complicated and expensive!
