Question 58Refrigeration & AC - QMED
70% to passIn refrigeration systems with multiple evaporators, the metering of refrigerant to each refrigerated space evaporator is accomplished by what device?
Athe individual thermal expansion valves
Bthe individual back pressure regulating valves
Cthe king valve
Dthe individual box solenoid valves
AI Explanation
The correct answer is A) the individual thermal expansion valves. In refrigeration systems with multiple evaporators, the metering of refrigerant to each refrigerated space evaporator is accomplished by individual thermal expansion valves. These valves automatically regulate the flow of refrigerant to each evaporator based on the temperature and pressure in that specific refrigerated space, ensuring proper cooling. The other options are incorrect because back pressure regulating valves, king valves, and box solenoid valves serve different functions in refrigeration systems and are not responsible for the individual metering of refrigerant to each evaporator.
