Refrigerant
Mechanical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A substance used as the working fluid in a refrigeration cycle that absorbs and releases heat through phase changes, typically evaporation and condensation. It circulates through the system to transfer thermal energy.
Example in context
“The technician charged the system with R-410A refrigerant to restore the air conditioner's cooling capacity.”
“Teknisyen, klimanın soğutma kapasitesini geri kazandırmak için sisteme R-410A soğutucu akışkan yükledi.”
Where engineers use it
Refrigerant selection affects system efficiency, environmental impact, and safety. Engineers must know properties like boiling point, latent heat, and global warming potential when designing or retrofitting HVAC systems.
Synonyms: coolant, working fluid
Practice: can you use “Refrigerant” at work?
During an HVAC retrofit, you need to replace an old R-22 system. Analyze the available drop-in refrigerants and choose the best one considering performance and regulations.
