What is the primary purpose of a liquid receiver?

• A. To expand the refrigerant
• B. To store liquid refrigerant
• C. To regulate pressure
• D. To measure refrigerant levels

Answer: (B)

The primary purpose of a liquid receiver is to store liquid refrigerant. In a refrigeration system, this component plays a critical role by collecting refrigerant from the condenser before it is distributed to the expansion device. The receiver ensures that there is a sufficient supply of liquid refrigerant available for the system to function efficiently. It helps maintain an adequate level of refrigerant, which is crucial for optimal performance during the cooling cycle. Other options focus on different aspects of refrigerant management but do not capture the main function of the liquid receiver. For instance, liquid expansion is typically the role of the expansion device, while pressure regulation is handled by components like pressure regulators. Measuring refrigerant levels is a function of other devices, such as sight glasses, rather than the primary role of the receiver itself. Thus, the correct answer highlights the essential function of storage within the refrigeration cycle.
