ane. high Humidity Causes Ducted Air Conditioner Grilles to Sweat

Air conditioner sweating occurs when boiling air in the domicile makes contact with the common cold surface of the ducted air conditioner grille. Sweating is likely to occur when the air temperature is below the dew point temperature.

The dew point temperature is the temperature at which water vapour will begin to course and turn into liquid. Just put, if the surface of your air conditioner grille is below the dew point of the room, then moisture volition begin to class.

In your roof space where it's much hotter the dew point temperature is also much college, this means that sweating of the ducts and other air workout equipment is more than likely to occur.

Examples

Let's get through an example, at our office today we have only closed all the windows & turned the air conditioner ON. Take a await at our indoor observations below after we airtight all the windows.

Indoor temperature: 22.ane°C
Relative humidity: 98%
Dew point: 21.eight°C.

So, if the external surface of the ducted aircon grilles in our role gets colder than 21.eight°C, we could expect water vapour to form and turn into a liquid. Every bit our air conditioner is set to 22°C and won't be running for a long time, the grilles don't accept the chance to sweat.

February is the almost boiling calendar month in Brisbane and also the month when nearly homeowners experience air conditioner sweating problems. Let's say it's an average February day and take a look at the dew point temperature.

Now we sympathise that if the external surface of the ducted aircon grilles in our home gets colder than 22.5°C, we can expect water vapour to course and turn into a liquid.

A ducted air conditioner typically provides a 10-12°C deviation in temperature between the air getting sucked through the return air filter grille and the supply air temperature coming out of the grille in your living room.

In this instance, the standard temperature difference would atomic number 82 us to a supply air temperature of 18.5°C. Equally this temperature is lower than the dew point, air conditioner sweating may occur once the metallic/plastic grille drops below this temperature.

The material of the grilles tin also impact the corporeality of condensation/ dripping water that comes off your air conditioner. Metal grilles are more than likely to crusade sweating. Plastic grilles is a meliorate alternative as they are less conductive than metal.
