An overview of compressor technologies used in chiller systems, focusing on their function, types, and performance characteristics. The session begins with a foundational explanation of the compressor’s role within the vapor-compression refrigeration cycle—highlighting its importance in maintaining pressure differentials and enabling efficient heat transfer.

By the end of this session, participants will be able to:

• Describe the role of the compressor in a chiller.
• Explain the operating principles of different types of compressors and the key differences between them.
• Identify appropriate compressor technology for a chiller in any given application.
