When the nitrogen gas is high, the stator temperature of the nitrogen and hydrogen compressor will increase, and the power will increase.

In actual production, when the nitrogen gas is high, the stator temperature of the nitrogen and hydrogen compressor increases, and the power becomes larger. Can you please discuss the reason?
The molecular weight of nitrogen is 28, and the molecular weight of hydrogen is 2. Under the same working conditions, compressing nitrogen consumes more energy than compressing air. Therefore, when the proportion of nitrogen in the hydrogen-nitrogen mixed gas increases, the average molecular weight of the mixed gas increases, the energy consumption of the compressor increases, and the difficulty of compression increases. The direct manifestation is that the stator temperature and exhaust temperature of the compressor increase.
What is said above is the positive solution. Compression power is inversely proportional to the molecular weight of the mixed gas.
