Lg Split Air Conditioner in Columbia – What Is Convection Cooling?
Convection cooling is any transfer of heat that occurs from a movement of fluid. Both liquids and gases can exhibit convection cooling, and the effect can be natural or forced. Natural cooling occurs from heat transfer due to changes in density of the fluid, such as hot air rising and cooler air sinking. Forced convection occurs when any external force is added to move the fluid, such as a fan moving air or a spoon stirring a liquid.
Heat transfer occurs primarily from conduction and convection. Conduction is a transfer of heat through any material, without movement of the material. An example of conduction is a metal pan heated by a flame on a gas stove. The gas flame heats the underside of the pan, and conduction will transfer the heat to the remainder of the pan. When the heat is turned off, convection will cool the pan as heat transfers and rises above to the air around the pan.
Split Airconditioner in Columbia – Evaporation.
Convection can be combined with evaporation to improve cooling performance. Evaporative cooling systems, which use forced air passed through a wet evaporation pad to cool interior spaces, are popular in areas of very low humidity. These systems cool the interior space by removing heat from the incoming air through evaporation.
The resulting air stream is cooler, but contains more moisture. Evaporative systems do not work well in areas of higher relative humidity, because cooling will not occur and the interior may become quite damp.
