Primary Variable Pumping System
Primary Variable Pumping System
Primary variable pumping systems directly circulate chilled water between chillers and air handling units serving metro stations and concourse areas. In metro applications, passenger density varies significantly during peak and non-peak hours, requiring dynamic load management.
Variable speed pumps automatically adjust flow rates to match cooling demand, improving energy efficiency and reducing wear on HVAC equipment. For underground metro stations in Indian cities with high ambient temperatures, primary variable pumping ensures stable climate control while minimizing power consumption.
