Vapor Compression Cycle
Mechanical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A thermodynamic cycle used in refrigeration and air conditioning systems where a refrigerant alternately evaporates and condenses by compressing and expanding. It transfers heat from a low-temperature reservoir to a high-temperature reservoir with work input.
Example in context
“The vapor compression cycle in this chiller achieves a coefficient of performance of 5.0 under full load conditions.”
“Bu soğutucudaki buhar sıkıştırmalı çevrim tam yük koşullarında 5.0 performans katsayısına ulaşır.”
Where engineers use it
Engineers use the vapor compression cycle when designing refrigeration and air conditioning systems. It appears in thermodynamic analysis of compressors, condensers, evaporators, and expansion devices to optimize energy efficiency and cooling capacity.
Synonyms: VCR cycle, compression refrigeration cycle
Antonyms: absorption refrigeration cycle
