Chillers typically use refrigerants such as R-134a, R-410A, or R-407C, depending on the system design and required cooling capacity. These refrigerants are selected for their efficiency, thermodynamic properties, and environmental impact. Recent regulations have also encouraged the use of low-GWP (global warming potential) refrigerants, such as R-32 or natural refrigerants like ammonia (R-717) and carbon dioxide (R-744) in some applications. The choice of refrigerant can significantly affect the chiller's performance and compliance with environmental standards.

The three main types of compressors used for chillers are reciprocating, scroll, and screw compressors. Reciprocating compressors use pistons to compress refrigerant, offering high efficiency for lower capacity applications. Scroll compressors utilize two spiral-shaped components, providing quieter operation and higher efficiency for medium capacity systems. Screw compressors, ideal for larger applications, use two interlocking screws to compress the refrigerant, delivering high efficiency and reliability in continuous operation.
