Which component is responsible for stopping refrigerant flow in a refrigeration system?

• A. Accumulators
• B. Solenoid valves
• C. King valves
• D. Compressors

Answer: (B)

The component responsible for stopping refrigerant flow in a refrigeration system is the solenoid valve. Solenoid valves function as electrically operated devices that can open or close based on electrical signals. When the solenoid is energized, it allows refrigerant to flow through the system. When it is de-energized, the valve closes, effectively stopping the flow of refrigerant. This capability is crucial for controlling the refrigeration cycle and managing system operations, including safety measures and efficiency. Other components mentioned, such as accumulators, king valves, and compressors, serve different functions in the refrigeration system. Accumulators store refrigerant to ensure that the evaporator does not become flooded, king valves are typically used for service and maintenance purposes to isolate parts of the system, and compressors are responsible for compressing refrigerant and maintaining circulation within the system. Understanding these roles emphasizes the unique function of solenoid valves in controlling refrigerant flow.
