Noise of cooling systems is environmental pollution, expert says

Kuenzelsau, Baden-Wurttemberg, Germany, 30 August, 2018: “Cooling and fresh air machines must be silent and must consume less energy!” Masahiro Tsujimoto, Managing Director, Ziehl-Abegg Japan, said, during an international conference in the German Fan Valley. “We must be able to reduce the big energy consumption of cooling machines in Japan and reduce the noise of these machines,” he added.

“The requirements changed during the past 100 years,” Tsujimoto said. “In the beginning, the focus was on the life period, later on the ventilation system performance. The energy consumption has been important for roughly 20 years. Furthermore, people evaluate noise as pollution of the environment or as noise disturbance in the past few years,” he added.

Tsujimoto explained: “There are two possibilities – the planning of new buildings and the refurbishment of existing buildings. The ventilation system of old buildings is often too noisy and consumes too much energy. If you need current calculation software for the needs and refurbish with energy saving fans, it is not necessary to modify the tube system.”
