Prevent condensation in a solar water heater?.
How can I prevent condensation in a solar water heater collector. I to try to make air-tight box and then fill the box with silica gel after isolation. Does anyone have a better idea. I think a wooden air-tight glass box will be difficult.
I doubt that really can "prevent" the condensation of conventional solar panels placed outdoors in a temperate climate, and finally, the temperature of the materials to be below the dew point box surrounding air and condensation forms. You can ventilate the collector to provide airflow to dry quickly condensation Once the solar radiation has begun, and this would prevent further loss of refraction in the condensation that would result in a vent manifold, where condensation is walking for a long time. You must also minimize long-term growth of fungi and the film bacteria, what really killed his solar performance. But the most effective collectors are solar glass often recover completely, or create them as "tubes within tubes "that are permanently sealed and transferred to the life of the vacuum unit and the empty bottles at large thermos.
