WebJun 15, 2024 · Tips to Improve Chiller Plant Efficiency. Keep tubes clean for efficient heat transfer: – Heat transfer has the greatest single effect on chiller performance. Large chillers can have more than five miles of condenser and evaporator tubes, so high heat transfer is fundamental to maintaining efficiency. Treat condensate water: – Proper water ... 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
WebSep 19, 2024 · 3.2 Performance Improvement-Energy-Efficiency by Retrofit of Water-Cooled Chiller. By optimization of chiller and making it energy efficient, the building energy consumption decreased. The performance improvement obtained is studied, by comparing the monthly energy consumption before and after the retrofit. WebIn many chiller systems, cooling towers are added to increase the efficiency of heat removal from the condenser, thereby increasing energy efficiency. The water consumption at the power plant and the building must be studied and documented to evaluate the overall water efficiency of different types of building cooling systems.
