Dnone of these
Answer
Correct Answer: 70 to 110° C
Explanation
Cycle insightCompressor discharge temperatures for NH₃ are typically high due to significant superheat at elevated pressure.
Typical valuesRepresentative discharge: ~70–110°C depending on suction superheat, pressure ratio, and compressor type.
Final Answer70 to 110° C.
