Question

Quizplus · Accepted Answer

Superheat is the best method of checking to see when a refrigerant coil has a proper level of refrigerant because it measures the temperature of the refrigerant vapor leaving the evaporator coil and compares it to the saturation temperature of the refrigerant at the current pressure. This allows the technician to ensure that the refrigerant is fully evaporated in the coil and not flooding back to the compressor as a liquid, which can cause damage. Boiling temperature, dry heat, and vapor temperature can provide some information about the system, but superheat is the most accurate and comprehensive method.
