Energy-saving EC centrifugal fans in fan coils
Cost savings through efficient components
Increasing energy costs and legal regulations contribute to the fact that the comprehensive consideration of buildings in terms of their efficiency is playing a bigger and bigger role. High energy savings potential can be attained if the right technology is used in ventilation and air-conditioning technology such as for climate control systems where the fans run almost around the clock.
Fan coils (fan convectors) are parts of a central air-conditioning unit with the task of cooling or heating air in circulation and are therefore operated on long duty cycles. Therefore, it makes financial sense to invest in energy-efficient components in their design. Fan coils belong to the group of air-to-water air conditioning units, so their principle function is easy to understand: Depending on the requirements, heated or cold air flows through the built-in heat exchanger. Using the fan, air is guided past the heat exchanger, which provides heating or cooling of the room air.
ebm-papst developed energy saving and quiet fans in various models for the fan coil application area. These fans in GreenTech EC technology deliver air volumes up to 2,200 m³/h in the power range between 40 and 250 watts. All of the models are designed specially for low-noise operation and are highly compact. Because the EC motors integrated into the fans also work with great efficiency, they consume substantially less energy than conventional AC drives.However, these potential energy savings are realised not only when operated under full load, but also primarily when operated under a partial load, i.e. when the speed is controlled on-demand to correspond to the current temperature requirement.EC motors then lose far less efficiency than asynchronous motors with the same output.
Even for existing installations, fans that are already installed can easily be exchanged with new energy saving GreenTech EC fans due to the simple plug and play solution. So state-of-the-art technology proves once more to be simply the better choice – in terms of energy savings as well as for comfort.
