Question 13Refrigeration/AC - 1st Asst/Chief70% to pass
When a refrigeration system is being topped off with a small amount of refrigerant through the low side with the compressor running, what should be done?
AI Explanation
The correct answer is C) the refrigerant should be charged into the system as a vapor.
When topping off a refrigeration system with a small amount of refrigerant, it is important to charge the refrigerant as a vapor rather than a liquid. Charging liquid refrigerant into the low side can damage the compressor. The vapor will properly mix with the existing refrigerant in the system. Charging as a vapor ensures the refrigerant is distributed evenly and absorbed properly, without causing any harm to the compressor. The other options are incorrect because they are not the proper procedure for safely topping off a refrigeration system.
