Increase chiller efficiency
WebJul 15, 2024 · Most engineers design the chiller system at 5°C delta T on both the chilled water side and also on the condenser side if the chiller is water cooled. This is the old way to design a system but due to the need for energy efficiency, we need to increase delta T to 8 – 10°C to reduce the flow rate so we can select smaller pumps to reduce ... WebKeep condenser flow velocity between 3 and 11 feet/second (FPS) Proper condenser water flow velocity directly impacts chiller performance and can help reduce condenser tube fouling. Too low a flow velocity reduces chiller efficiency and ultimately leads to laminar flow. Too high a flow velocity leads to vibration, noise, and condenser tube erosion.
