← ScienceWithin a refrigeration system, which process induces cooling?
A)Forced evaporative cooling of refrigerant✓
B)Compressor increasing refrigerant saturation pressure
C)Expansion valve superheating the gas
D)Condenser isobarically desuperheating vapour
💡 Explanation
Forced evaporative cooling causes a phase change, a liquid absorbing latent to turn to vapour and thus cooling, because increased heat of vaporization occurs at lower pressures; therefore the cooling effect is strongest here, rather than just using pressure or heat.
