The large volume of air pushed by an elevator traveling at high speed can create a lot of unpleasant noise inside the passenger car. Two high-speed elevators passing each other in a common hoistway creates forces that need to be fully understood before they can be harnessed into a quieter and more energy-efficient elevator installation. Mitsubishi Electric's analysis technology displays a visual demonstration of vector distribution of airflow and pressure distribution on car surfaces, which helps answer questions about performance that ensures a higher quality installation.
