Question 175Refrigeration/AC - 1st Asst/Chief70% to pass
If a refrigeration system were short of refrigerant, besides an elevated box temperature, what would be an observable symptom?
AI Explanation
The correct answer is C) continuous running of the compressor.
When a refrigeration system is short of refrigerant, the system will not have enough refrigerant to effectively cool the refrigerated space. This will cause the compressor to run continuously in an attempt to reach the desired temperature, but it will be unable to do so due to the lack of refrigerant. The other answer choices are incorrect because they do not accurately describe the symptoms of a refrigerant shortage. A short cycling compressor is typically caused by a different issue, such as a water failure, and high suction or discharge pressures can have various causes, but are not the primary symptom of a refrigerant shortage.
