What kind of refrigerant do chillers use?

Answer 1

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.
