Question 112Refrigeration/AC - 1st Asst/Chief70% to pass
Which of the following electrically operated refrigeration system valves would be most appropriate for use as a 2 position diverting hot gas bypass solenoid valve? Illustration GS-RA-19
AI Explanation
The correct answer is B.
The 2 position diverting hot gas bypass solenoid valve would be most appropriately represented by option B in the illustration GS-RA-19. This type of valve is used to direct the refrigerant flow in a refrigeration system, allowing the hot gas to bypass the condenser coil during the defrost cycle. The solenoid valve operates in a binary fashion, either fully open or fully closed, making it suitable for this 2 position diverting application.
The other options, A, C, and D, represent different types of refrigeration valves with more complex functions, such as variable metering or modulating control, which would not be the most appropriate choice for this specific application.
