Water Cooled Chiller System - Complete Piping & Working Guide Understanding a Water Cooled Chiller System is essential for every HVAC & MEP engineer involved in commercial, industrial, airport, hospital, and data center projects. This diagram clearly explains the complete flow between: Cooling Tower Chiller Chilled Water Pumps Condenser Water Pumps Heat Exchanger Flow & Temperature Monitoring Devices ◆ How the System Works: Chilled Water Supply (CHWS) at 6-7°C is circulated to the building/process load. Heat from the space is absorbed and returns as CHWR at 12-15°C. The chiller evaporator removes heat from the chilled water loop. Heat is transferred to the condenser water circuit. Cooling tower rejects unwanted heat to the atmosphere. Cooled condenser water returns back to the chiller for continuous operation. ◆ Key Engineering Points: Water-cooled chillers provide higher efficiency compared to air-cooled systems. Proper ΔT (temperature difference) is critical for energy pe...
