The dew point is the varying temperature at which atmospheric humidity condenses. If the air temperature drops below the dew point, dew and condensation form.
The capacity becomes smaller, and the water condenses out (the source of fog).
Air above a cold or cooled surface contracts and falls.
Condensation happens when a gaseous substance (a substance which is in a gas state) is cooled sufficiently to revert it back into a liquid state.
The air cooling of a chiller signifies , the cooling of radiator. in a chiller the compressor compressors the gas which on expansion cools in side Copper tubes causing the chilling effect. The refrigerants get heated up when compressed in a compressor. this heated refrigerant is cooled by blowing air in air cooled chillers. There are also water cooled chillers.
Advection fog results when moist air moved across a cold surface. When moving across a cold surface, the air is cooled to its dew point.
Condensation
supercooled
Relative humidity increases
clouds form when the air is cooled to its dew point
When the air is cooled it mostly rains
As air molecules are cooled, they condense and form a liquid, and if cooled even further, will form a solid.
This describes what happens in a convection cycle.
The temperature to which air must be cooled to reach saturation is called the dew point.
When a paracel of air is cooled to the temperature at which it is saturated, it has reached its dew point.
