PROBLEM TO BE SOLVED: To provide a vapor compression system having an air-cooled condenser operable at a lower condensation temperature when an ambient air temperature is extremely high in order to maintain intended performance and efficiency.SOLUTION: A vapor compression system includes: a first circuit having a first compressor 42, a first condenser 80 and a first evaporator 48; a second circuit having a second compressor 42, a second condenser 82 and a second evaporator 48; and a ventilation device 32 for circulating air through the first condenser 80 and then through the second condenser 82. In the vapor compression system, the first and second evaporators 48 are configured to perform heat exchange from one process fluid, and the first and second condensers 26 have planer sections, respectively and are disposed adjacent to each other and in parallel with each other. Each section of the first condenser 80 is thermally separated from a corresponding section of the second condenser 82. A condensation temperature of the first condenser 80 is lower than that of the second condenser 82. |
