Why is there condensation at the indoor unit's air outlet of a split air conditioner?Updated 2 months ago

The condensation at the air outlet of the indoor unit in a split air conditioner occurs due to the following reasons:

1. Humidity during the cooling process: When the air conditioner is set to a low temperature or the indoor humidity is high, the indoor unit removes heat from the air and cools it. During this process, the water vapor in the air condenses into liquid form, resulting in condensation. This happens because the cooled air cannot hold all the moisture present in it.
2. Air conditioner design: The design of the indoor unit may contribute to the condensation of water vapor at the air outlet. The metal surface surrounding the outlet is typically colder than other areas, making it easier for water vapor to condense into water droplets there.

To minimize condensation at the air outlet of the indoor unit, consider the following measures:

1. Control indoor humidity: Maintain indoor humidity within a reasonable range by using a dehumidifier or ensuring proper ventilation.
2. Adjust the air conditioner temperature appropriately: Avoid setting the temperature too low to reduce the condensation of water vapor during air cooling.
3. Regular maintenance of the air conditioner: Clean the air conditioner filters and the indoor and outdoor units to ensure proper functioning, and make sure there is no excessive dust or dirt buildup around the air outlet.
