Question: What is the consequence of excessive superheat at the evaporator outlet?
Answer options: ✅ Reduced system capacity and potential overheating of the compressor.
- Increased system capacity and improved compressor lubrication.
- Reduced energy consumption of the compressor.
- Formation of liquid refrigerant in the suction line.
Correct answer: Reduced system capacity and potential overheating of the compressor.
Explanation: Excessive superheat means less refrigerant is boiling in the evaporator, leading to reduced cooling capacity and the compressor working harder to compress less dense gas, potentially leading to overheating.
