Which component stores liquid refrigerant in a refrigeration system?

The component that stores liquid refrigerant in a refrigeration system is the receiver. In a typical refrigerant cycle, after the refrigerant has been condensed from a gas to a liquid in the condenser, it must be stored temporarily before flowing into the evaporator. The receiver serves this purpose by holding the liquid refrigerant, ensuring that the system has a steady supply available to maintain continuous operation.

This storage is crucial because it allows for the refrigerant to be collected and separated from any vapor that could remain post-condensation. The receiver is designed to manage the refrigerant flow and pressure, which is key for the effective operation of the refrigeration system.

Other components play different roles: the evaporator is where the refrigerant absorbs heat from the environment to evaporate into a gas; the filter-drier removes moisture and contaminants from the refrigerant; and the sight glass helps indicate whether there is liquid refrigerant present in the system, but it does not store it.
