Question 125Refrigeration/AC - 1st Asst/Chief70% to pass
In the multi-evaporator refrigeration system shown in the illustration, what is the proper name for the valve labeled "29"? Illustration GS-RA-12
AI Explanation
The correct answer is C) chill box thermostatic expansion valve.
This is the correct answer because the valve labeled "29" in the multi-evaporator refrigeration system illustration GS-RA-12 is responsible for regulating the refrigerant flow into the chill box evaporator. The thermostatic expansion valve controls the amount of refrigerant entering the evaporator based on the temperature and pressure in the chill box, ensuring proper cooling.
The other options are incorrect because they do not accurately describe the function of the specific valve labeled in the illustration. Option A refers to a pressure regulating valve, option B refers to the freeze box evaporator, and option D refers to a solenoid valve, which is a different type of refrigeration component.
