How to change the direction of evaporation and thus location of condensation?
The simple answer is that water evaporate where the concentration in the air is lower than the vapor pressure some liquid water at a given temperature. Then it will condense at a location where the temperature is lower that the saturation temperature of water at that partial pressure.

Industrially, though, one widely used technique to avoid condensation when the surface temperature is low enough for it to happen is to use hydrophobic coatings to prevent the water vapor from nucleating on certain surfaces. A quick google search will reveal lots of these for different applications.
