Hi everybody,
first, please forgive my bad english
My question is:
In a 2 stage cicle with ammonia overfeed, what option is better:
1) discharge from low stage compressor (-30, -10) to a subcooler where there is subcooling of liquid feeding -30ºC separator
2) or discharge from LS compressor directly to separator at -10ºC
I think is better a subcooler because that way the separator is not inflenced for the discharge from LS compressor,
are there differences in returning of oil from compressors ?
thank you for your help
