Which statement about a liquid receiver in a refrigeration system is true?

• A. It heats refrigerant before entering the condenser.
• B. It compresses refrigerant.
• C. It stores liquid refrigerant and is permanently connected to the system by inlet and outlet pipes.
• D. It filters refrigerant.

Answer: (C)

A liquid receiver is a storage vessel on the high‑pressure side of a refrigeration system. Its main job is to hold liquid refrigerant and remain permanently connected to the system via inlet and outlet pipes. By providing a reserve, it helps ensure a steady supply to the metering device and smooths out changes in demand or charge, especially in systems with varying loads or multiple compressors. It isn’t involved in heating the refrigerant before it reaches the condenser, nor does it compress the refrigerant. Filtration is handled by separate components (like a filter-drier) rather than the receiver itself. So the statement that it stores liquid refrigerant and is permanently connected to the system by inlet and outlet pipes best describes its function.
