What component stores liquid ammonia and provides a stable supply to the evaporators?

• A. The accumulator
• B. The condenser
• C. The receiver
• D. The evaporator

Answer: (C)

A reservoir that holds liquid refrigerant after it’s condensed and can feed a steady flow to the evaporators is essential. That role is filled by the liquid receiver. It stores the condensed liquid so there’s always enough on hand to meet evaporator demand and to smooth out variations from compressor cycling and changing cooling loads. By providing this buffer, the receiver helps ensure the metering device and evaporators receive a consistent supply of liquid refrigerant.

The condenser’s job is to remove heat and condense vapor into liquid; it isn’t a long-term storage vessel. The evaporator is where the refrigerant absorbs heat and boils to provide cooling, not where liquid is stored for distribution. The accumulator sits on the suction side to capture any liquid returning from the evaporators and protect the compressor, rather than supplying liquid to the evaporators.
