In a vapor-compression refrigeration cycle, the high-pressure side includes components that handle refrigerant after it has been compressed and condensed. After leaving the condenser, the high-pressure liquid flow is stored in a receiver before it goes to the expansion device. The receiver’s job is to hold this high-pressure liquid and provide a steady, reliable supply to the metering/expansion stage, while keeping liquid from mixing back with vapor and smoothing out fluctuations in flow. Because the refrigerant inside the receiver remains at high pressure, it is clearly part of the high-pressure portion of the cycle. The other options—evaporator and suction line—operate on the low-pressure side, and the condenser, though also high-pressure, is not the component that specifically defines the high-pressure side in the way a receiver does by storing high-pressure liquid before expansion.
