WebHigh efficiency chiller: Chillers spend about 95% of their operating hours at part-load conditions. In new high efficiency chillers the compressor is coupled with a variable frequency drive (VFD); the chillers are consider-ably more efficient since the VFD allows to oper-ate at increased efficiency at part-load. Moreover, Webimprove chiller efficiency is to increase the heat exchanger’s surface area— add more tubes to the evaporator and/ or condenser. More tubes result in a greater flow area and a lower design fluid velocity. A higher minimum flow is required to maintain sufficient fluid velocity to prevent laminar flow conditions. Laminar operation can lead 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 ... pom flying club
