What is the purpose of a receiver in a refrigeration system?

• A. Store refrigerant
• B. Absorb heat
• C. Compress refrigerant
• D. Measure pressure

Answer: (A)

The main idea here is that the receiver serves as a storage vessel for liquid refrigerant on the high-pressure side of the system. Placed after the condenser, it acts as a reservoir that ensures a steady supply of liquid to the metering device, helping the system handle changes in load or during charging. It also allows liquid to settle and any vapor to separate before entering the expansion device, reducing the risk of vapor reaching the metering valve. This function is specific to storage and buffering of the liquid refrigerant, not to absorbing heat, compressing the refrigerant, or measuring pressure.
