Question 156Refrigeration/AC - 1st Asst/Chief70% to pass
Moisture entering a typical refrigeration system will most likely produce what effect?
AI Explanation
The correct answer is B) freeze in the expansion valve.
Moisture entering a refrigeration system will most likely freeze in the expansion valve. The expansion valve is the coldest point in the refrigeration system, with temperatures often below freezing. Any moisture that enters the system will turn to ice and accumulate in the expansion valve, disrupting the proper flow of refrigerant and causing problems in the operation of the system.
The other options are incorrect because: A) the condenser is designed to operate at higher temperatures and would not cause the moisture to boil, C) the liquid line strainers are not designed to remove moisture, and D) the evaporator coils would experience sweating and frost due to the moisture freezing, but this is a symptom of the problem occurring in the expansion valve.
