There are a few things in common with all of the above scenarios:
- It is warm and humid in your environment or in the air you breathe.
- As the warm, humid air comes into contact with the cooler surface, it becomes much more humid.
A human can evaporate water or convert it into vapor at any temperature they choose, though it may evaporate more slowly is always getting water added to it somehow. Water vapor can readily be held in warm air because it is less dense than cold air.
If the temperature of the air is cold enough, water no longer exists as a vapor. It condenses back into a liquid once the air is warm and humid. Fog can be seen in nature as a result of this. It is also possible for the surrounding air to condense when it comes in contact with a much colder surface for an extended period of time. A liquid is formed on the surface as a result of the condensation of water vapor. Condensation occurs in your RV in the winter as a result of the latter method.
When winter RVing, how do you stop condensation?
Winter RVers may experience high relative humidity in their rigs even if the relative humidity outside is not that high.
You have a high relative humidity inside your RV for two reasons:
- You can conserve money and energy by keeping your RV closed as much as possible and preventing hot or cold air from escaping.
- Even breathing adds humidity to the air, as do propane stoves, showers, and bringing in wet or snowy clothes to dry.
Our rigs are heated to keep them comfortable, which means that the warm air inside can hold more water vapor than the air outside. A poorly insulated and cold RV’s poorly insulated walls or windows are constantly fighting wet and possibly moldy conditions when this warm and humid air comes in contact with them.
