Question

Quizplus · Accepted Answer

Fractionation occurs when some of a blended refrigerant evaporates or condenses before the rest of the blend. Option B is incorrect because it describes the process of partial charging, not fractionation. Option C is incorrect because operating pressures do not directly cause fractionation. Option D is partially correct but not the best choice because only option A is directly related to fractionation.
