Question 223Refrigeration & AC - Assistant Engineer
70% to passWhich 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
AA
BB
CC
DD
AI Explanation
The correct answer is B. The hot gas bypass solenoid valve in a refrigeration system is used to divert hot refrigerant gas around the condenser to maintain system pressure and temperature. Based on the illustration GS-RA-19, option B represents a 2-position solenoid valve, which is the most appropriate type for this application compared to the other options presented. The other options, such as thermostatic expansion valves (A) or pressure-regulating valves (C and D), are not designed for the specific function of hot gas bypass in a refrigeration system. A 2-position solenoid valve can effectively control the flow of hot gas to maintain the desired operating conditions.
