1. Air-Cooled Screw Chillers

Air-cooled screw chillers use the natural air to cool the refrigerant, which flows through the evaporator. They are commonly used in areas where water is scarce or expensive. Air-cooled screw chillers are also suitable for small and medium-sized buildings.

2. Water-Cooled Screw Chillers

Water-cooled screw chillers use water as a coolant. They are more efficient than air-cooled screw chillers and are generally used in larger buildings, such as commercial or industrial buildings. Water-cooled screw chillers require a cooling tower and a water pump for their operation.

4. Variable Speed Screw Chillers

5. Oil-Free Screw Chillers

Oil-free screw chillers use a magnetic bearing system instead of oil to support the compressor shaft. This eliminates the need for oil changes and reduces maintenance costs. Oil-free screw chillers are also environmentally friendly and quiet.

2. Energy Efficiency

The energy efficiency of a screw chiller is measured by the energy efficiency ratio (EER) or the coefficient of performance (COP). A more efficient chiller will be more cost-effective in the long run.
