Destratification (other)
Destratification may refer to: * Thermal destratification, mixing air to reduce stratified layers of heat that become trapped near the ceiling in buildings * Lake stratification Lake stratification is the tendency of lakes to form separate and distinct thermal layers during warm weather. Typically stratified lakes show three distinct layers, the Epilimnion comprising the top warm layer, the thermocline (or Metalimnion) ...

Thermal Destratification
Thermal destratification is the process of mixing the internal air in a building to eliminate stratified layers and achieve temperature equalization throughout the building envelope. Thermal stratification in buildings Destratification is the reverse of the natural process of thermal stratification, which is the layering of differing (typically increasing) air temperatures from floor to ceiling. Stratification is caused by hot air rising up to the ceiling or roof space because it is lighter than the surrounding cooler air. Conversely, cool air falls to the floor as it is heavier than the surrounding warmer air. In a stratified building, temperature differentials of up to 1.5°C per vertical foot is common, and the higher a building's ceiling, the more extreme this temperature differential can be. In extreme cases, temperature differentials of 10°C have been found over a height of 1 meter. Other variables that influence the level of thermal stratification include heat generated ...
