Water Cooled Condenser, Shell & Tube Type, Cooling Water Circuit & Water Quality Requirement

Shell and tube water cooled condenser: high pressure refrigerant gas outside tubes, cooling water flows inside copper tubes for heat exchange. Heat transfer efficiency is higher than air cooled type, stable condensing temperature, suitable for large rack unit and high heat load. Cooling water takes heat away and flows to cooling tower for re-cooling; water system needs water pump, pipeline, water treatment. Water quality control is critical: high hardness water causes scale attached on inner tube wall, heat transfer capacity drops sharply. Xiteliduo shell and tube condenser adopts seamless copper tube, can be matched with open type or closed cooling tower. Water flow rate must keep within design range; insufficient water flow leads to high condensing pressure; excessive flow wastes pump power. Water side chemical cleaning is required periodically; scale, slime and algae are hard to remove once thickened. Winter low ambient region needs water circuit anti-freeze: drain water, add antifreeze or install tracing heating cable. Water cooled system has more auxiliary equipment, higher initial investment and maintenance cost than air cooled solution. Refrigeration maintenance & repair company monitors water inlet/outlet temperature difference to judge fouling degree.
