Improvement Case 2 [Office Building] Stopping the Cooling Fan Belt Noise

Gentle acceleration is achieved by the inverter, eliminating belt squeal at startup and extending lifespan.

When the cooling fan starts, the belt that drives it slips, causing a squeaking noise as it rubs against the pulley. Due to its installation on the rooftop, complaints have arisen from nearby apartments. Because the fan turns on and off dozens of times a day depending on the set temperature, there have been many complaints, and the belt has also experienced significant wear. This issue has been improved by implementing gentle acceleration through an inverter, which eliminates the belt squeak and extends its lifespan. 【Features】 ○ Control method: Gentle acceleration operation using an inverter ○ Target equipment: Cooling fan (for air-cooled heat pump chiller) (5.5kW × 2 units) For more details, please contact us or download the catalog.
