Where is the receiver dryer located?

• A. after evaporator before compressor
• B. before evaporator after compressor
• C. after condenser before metering device
• D. before condenser after metering device

Answer: (C)

In a typical vapor-compression refrigeration cycle, the receiver-drier lives on the high-pressure liquid line after the condenser and before the metering device. This placement ensures that liquid refrigerant is stored and that any moisture or contaminants are removed before the liquid enters the expansion device. The dry, clean liquid is essential for proper metering and operation; moisture can cause problems like corrosion, acid formation, and ice buildup in the metering device, which disrupts flow and cooling performance. If the receiver-drier were placed anywhere else, moisture or contaminants could reach the metering device or evaporator, or vapor could enter the expansion valve, compromising efficiency and components.
