What are the two basic categories of chillers?

• A. Compression cycle and absorption
• B. Gas and liquid
• C. Single-stage and multi-stage
• D. Electric and mechanical

Answer: (A)

The two basic categories of chillers are indeed classified as compression cycle and absorption. Compression cycle chillers, also known as vapor-compression chillers, use a refrigerant that cycles through a compressor to increase pressure and temperature, subsequently dissipating heat through a condenser. This method is widely used due to its efficiency in cooling applications, especially in commercial settings. On the other hand, absorption chillers operate using a different mechanism. They utilize a heat source, such as natural gas or steam, to drive the refrigeration cycle, relying on the absorption of refrigerant by a secondary fluid. This makes them suitable for environments where waste heat is available or where electrical consumption needs to be minimized. While the other options mention different forms or types of chillers, they do not capture the fundamental classification of chillers as effectively as the compression cycle and absorption categories do. Understanding these categories is crucial for selecting the right chiller for specific applications and understanding their operational principles.
