🔍 Key Concepts

• Superheat in a thermostatic expansion valve (TXV): what it measures and why it is set to a certain value • What happens in the evaporator outlet and suction line when there is not enough superheat (too much liquid refrigerant leaving the evaporator) • The risk of liquid refrigerant reaching the compressor and why that is dangerous

💭 Think About

• Think about what a LOW superheat setting means for the condition of the refrigerant at the outlet of the evaporator: is it mostly vapor, or is there still some liquid present? • If more liquid leaves the evaporator, how will that affect the temperature/feel of the suction line and what might happen inside the compressor? • Which of the answer choices describes a situation where the refrigerant is not fully vaporized before entering the suction line?

✅ Before You Answer

• Review the definition of superheat: temperature of refrigerant vapor above its saturation (boiling) temperature at that pressure • Consider whether a warm suction line suggests more or less liquid present in the suction line • Ask: if liquid is not fully boiled off in the evaporator, where does it go and what symptom in the options best matches that condition?
