The design and operation of water distribution systems can significantly impact chiller efficiency. For example, improper pipe sizing, inadequate insulation, and poor system balancing can all lead to reduced chiller efficiency. Additionally, the type of water distribution system used can affect chiller performance, with 4-pipe systems generally providing better heat rejection and more efficient chiller operation. Proper design, installation, and maintenance of water distribution systems are critical to ensuring optimal chiller efficiency and overall system performance.
