A water-cooled screw chiller is a refrigeration system used to cool water for industrial and commercial applications. It uses a screw compressor and a water-based cooling system (usually with a cooling tower) to remove heat efficiently.

These chillers are widely used where large cooling capacity and continuous operation are required.

Working Principle

A water-cooled screw chiller operates on the vapor compression refrigeration cycle, which includes four main processes:
compression → condensation → expansion → evaporation

Main Components

  • Screw compressor
  • Evaporator
  • Condenser
  • Expansion valve
  • Cooling tower
  • Pumps and control system
