Air Turnover In a building with high ceilings, such as a warehouse or manufacturing facility, thermal barriers are established as warm air rises and gets trapped at the ceiling. The result, known as "air stratification," creates layers of temperature in the space. The temperature at the ceiling may be 25 degrees hotter than at the floor, and the heat trapped at the higher level is unusable. Since the desired building temperature must be maintained at a low level, the inevitable result is excessive heating bills. Air stratification also creates problems in spaces that require cooling. Because cool air settles to the floor, higher levels remain too warm. When the temperature is not uniform from floor to ceiling, condensation can form causing moisture damage. An Air Turnover system solves the air stratification problem by continuously circulating the air in the space. It picks up air at the floor, removing the coldest air layer supporting the thermal barrier. The air is heated or cooled, and returned quietly through a screened discharge plenum to create a uniform temperature and a comfortable, more cost-effective conditioned space. The Air Turnover principle eliminates air stratification in large open space buildings. It does this by recirculating the hot air which becomes trapped at the higher levels. The uniform room temperature improves comfort, conserves energy, eliminates thermal barriers, and reduces the possibility of condensation forming on stored materials.
