What is stratification and destratification? 
In buildings with high ceilings warm air, being lighter, rises to the ceiling, leaving denser, colder air at the floor level causing temperature disparities. This phenomenon is called thermal stratification and it can become a significant concern. This natural process leads to considerable temperature differences within the space. Stratification not only drives up energy bills but also it can be a potential strain on your heating systems and compromises occupant comfort. The solution lies in strategically implementing destratification fans, which effectively combat this energy-guzzling phenomenon. Destratification consists in bringing the layer of warm air that is near the ceiling back down. Thanks to this, the thermal energy in the room is redistributed evenly.
How does the destratification process work?
Destratification is the active approach to counteracting the effects of stratification. It is a process of continuously circulating air from the ceiling to the floor, breaking up the layers of stratified air. Destratification is achieved by using ceiling fans that bring the warm air back down. This dynamic air movement balances temperature differentials, creating a more comfortable environment without the need for excessive heating or cooling. By eliminating thermal layers, these fans contribute to improved air circulation, customer satisfaction, and heightened employee productivity. The reduction in temperature differences between ceiling and floor levels not only enhances comfort but also reduces strain on your heating system and leads to substantial energy savings.
Key benefits of destratification
Balancing temperatures: Constant air mixing is used to regulate room temperature, ensuring a consistently comfortable environment.
Energy and cost savings: Destratification can significantly reduce heating and cooling costs. When warm air is evenly distributed, thermostats can be set to lower values during winter and higher values during summer without negatively affecting room comfort. This leads to less energy consumption and lower electricity and gas bills.
Reduces strain on your heating system: By balancing temperatures through air mixing, a more consistent temperature in the space is achieved. When heating and cooling systems do not have to work as intensively, there is less wear and tear on these devices. This can extend their lifespan and reduce maintenance and repair costs.
Improved room comfort: By equalizing air temperature, destratification fans reduce costs and enhance overall comfort levels in buildings. In this way, building occupants do not have to deal with unpleasant temperature differences, which can improve their productivity and well-being.
How to control ceiling fans?
Now that we've explained how destratification works, let's take a look at how it can be applied in practice. Effective air destratification uses different components and strategies. A key element of this process are special fans designed to circulate the air, known as destratification or ceiling fans. These fans are strategically placed in the space to disrupt the natural stratification of air, redistribute warm air from the ceiling downwards, and improve overall air circulation.
In addition to fans, control systems are necessary to optimize destratification. At Sentera, we offer advanced control solutions designed specifically for this purpose. Our controllers automatically turn on fans based on temperature differences or pre-set times. Setting up these controllers is simple – once you place the sensors (one near the floor and one near the ceiling) and connect them to our destratification controller, you're almost done. The last step is to connect the destratification fan to this controller and configure it.
These systems can adjust the fan speed to meet the specific needs of a given space, ensuring optimal air movement. Another important aspect of maintaining air quality is proper ventilation to prevent stagnation. Factors such as building design, ceiling height, layout, and insulation affect the effectiveness of destratification measures. These factors determine the location and size of destratification fans and influence air circulation patterns.
Regular maintenance is essential to ensure the longevity and efficiency of your destratification equipment. This includes regular cleaning, lubrication, and inspection of fans and controls. Monitoring air quality and temperature levels can help detect any deficiencies or problems and encourage timely maintenance. While HVAC systems typically require maintenance twice a year, air quality monitoring can signal when maintenance is needed, ensuring optimal system performance.
Where is destratification used?
Destratification is effective not only in large commercial and industrial buildings but also in smaller spaces such as schools, offices, and homes. Investments in destratification fans often pay for themselves within a few years due to energy savings and lower maintenance costs.
- Industrial buildings: The high ceilings and large spaces of industrial buildings are ideal for destratification. Even distribution of heat can significantly reduce energy costs.
- Offices and commercial spaces: In offices and commercial spaces, destratification can improve employee and customer comfort, leading to increased productivity and satisfaction.
- Residential properties: In homes with high ceilings or multiple floors, destratification can help maintain a stable temperature and reduce heating and cooling costs.
Energy savings
As a powerful tool in the quest for energy efficiency, destratification fans play a pivotal role during both heating and cooling seasons. They effectively redistribute warm air and reduce energy consumption. For buildings with high ceilings, the benefits are particularly pronounced, making these fans a smart investment for long-term energy savings.
Destratification solutions
Sentera has developed both EC and AC fan speed controllers, the ECMF8 series for EC fans and the TCMF8 series for AC fans. Both series require application specific firmware to operate, which can be downloaded via SenteraWeb. Depending on the controller version, a separate internet gateway may or may not be required. Once the software has been downloaded, it can work stand alone or it can stay connected to SenteraWeb.
By creating and incorporating your own installation into this cloud platform, you can enjoy benefits such as:
- Easy remote monitoring or changing parameters and settings of connected devices
- Data logging: Create diagrams and export data, such as visualisation and recording of ceiling and floor temperatures
- Creating different regimes for your ventilation system, for example day-night regime.
- Receiving alerts or warnings when measured values exceed warning ranges or when errors or abnormalities occur
- Defining users and allowing them to log in to monitor the installation via a standard web browser
For easier installation Sentera offers complete packages that have everything you need for a specific function, we call them solutions. Check out also all of the other solutions that we have in the Solutions tab.
In conclusion, the use of destratification fans emerges as a multifaceted solution, addressing not only energy efficiency but also indoor air quality and overall occupant well-being. As buildings face unique climate challenges, the integration of destratification fans stands out as a strategic and sustainable choice for optimizing HVAC systems.
