In those situations the air conditioning system runs for longer periods of time.

Supply air grille sweating.

Condensation dripping from a ceiling vent can have detrimental effects on the ceiling material surrounding the vent as well as carpeting and. How to prevent condensation in ceiling vents. Are the grilles that are sweating close to an unconditioned room or a door to outside. Click to view dew point calculator.

While sweating may be a simple annoyance it may also be potentially dangerous. This colder surface then chills the surrounding air to a temperature below it s dew point which causes the water vapor to condense into a liquid just like on the outside of a glass of iced teas sitting outside on a hot day. Below is a dew point calculator that may help you see the correlation of the three values. At least one relay.

Sweating occurs when the warm moist room air contacts the chilled diffuser face while the supply air temperature is below the dew point temperature. Dew point is the temperature where water vapors in the air start going into a liquid phase. Are they close to any sources of water vapor like a kitchen. At least one humidistat positioned within said return air duct.

If air is able to escape around the ac vents rather than flow through the grates as it should it can cause condensation to build up and drip from the ac vents. Either way it is a symptom of a larger problem. Any time that the dewpoint in the room is greater than the supply air temperature and therefore the supply grille temperature you can have condensation on the grilles. The air temperature your conditioner is blowing out is below the dew point which causes the metal grill to sweat or condensate.

Condensation forms when warm humid air comes into contact with a colder surface like your air conditioner s ductwork. Sweating presents itself in an air distribution system as moisture that forms on the faces of lay in diffusers and t bar grids adjacent to those diffusers where this moisture collects and drips into the areas below. The easiest thing you can do to fix water leaking from your ac vent is to reach up and feel for any air escaping from around the sides of the air vent. It chills the metal diffuser and tries to maintain a comfortable inside temperature.
