Avoiding resonance-induced damage Every mechanical device with a rotating mass has a residual imbalance that stimulates vibrations. If the stimulation force coincides with the device's natural oscillation, this produces a state of resonance. The deflections in the resonant range may be so high that they damage the device, for example the fan. Speaker Uwe Sigloch will present fan solutions that can detect resonance and reduce its harmful effect. In this way, EC centrifugal fans can be operated across the entire speed range without becoming damaged. "Fans for AHUs – solutions to avoid resonance-induced vibrations" Speaker: Uwe Sigloch, Head of Product & Market Management at ebm-papst Mulfingen Date: Monday, March 11, 2019, 15:30 Venue: Air-Conditioning Forum in Hall 8.0 A19 / A31 Residential ventilation helps to improve the quality of ambient air Special fans that control both air intake and exhaust are needed for residential ventilation in both new and renovated buildings. Thanks to its precisely controllable air flow, the RadiCal centrifugal fan in a scroll housing is ideal for residential ventilation. The integrated volume constancy control enables effective residential ventilation without an overpressure or underpressure occurring in the living space. The speakers will also present a fan for monotube ventilation systems, designed to ensure a supply of fresh air in bathrooms and WCs that do not have a window. The air is exchanged through a central duct, which is why these systems are referred to as monotube ventilation systems. To meet the needs of this particular application, ebm-papst has developed an efficient system solution with EC fans and sophisticated on-board electronics. "Quiet and efficient system solutions for residential ventilation" Speakers: Lena Kern and Nikolai Lukin, both Sales Engineer Industrial Ventilation Technology at ebm-papst Mulfingen Date: Friday, March 15, 2019, 10:30 Venue: Building Forum in Hall 10.3 B10/B20
