Water-cooled chillers can use various types of compressors depending on the cooling requirements and system design. Here are the most common types:

1. Screw Compressors

Screw compressors are widely used in water-cooled chillers. They feature two interlocking screws that compress the refrigerant, providing high efficiency and capacity for large-scale applications.

2. Centrifugal Compressors

Centrifugal compressors use a rotating impeller to compress the refrigerant. They are suitable for high-capacity water-cooled chillers and are known for their energy efficiency and smooth operation.

3. Reciprocating Compressors

Reciprocating compressors employ pistons to compress the refrigerant. They are commonly used in medium-sized water-cooled chillers and provide reliable cooling performance.

4. Screw Compressors

Screw compressors are also used in water-cooled chillers due to their ability to handle varying loads effectively. They are known for their durability and efficiency in industrial applications.

5. Turbo Compressors

Turbo compressors are high-speed compressors used in certain water-cooled chillers. They offer high efficiency and are ideal for large-scale cooling applications with consistent load demands.

6. Scroll Compressors

Scroll compressors are less common in water-cooled chillers but can be used in smaller systems. They operate with two interleaved scrolls to compress the refrigerant and are known for their reliability and quiet operation.
