In the PID diagrams, the intercooler temperature is set at -25°C; the medium used in this intercooler is ethylene glycol. Could someone please tell me what code should be used to represent the inlet and outlet of the intercooler?
I’m not sure what you mean by intercooler, but it probably serves a cooling purpose as well. The codes for the cooling water used in our factory are as follows: cooling water inlet CW (cool water), and cooling water outlet CWR (cool water return). Like other pipelines, the materials that pass through them are generally denoted by abbreviations of those materials.
We usually use BWS and BWR; apart from -25, do you have any other temperatures?
HG/T20519 2009 also doesn’t contain the code for intercooling that you mentioned; please provide an explanation……
Our company has 25°C circulating water, -5°C normal cooling brine, -15°C medium cooling brine, and -25°C deep cooling ethylene glycol； All four of these are refrigerants. CWS is used for circulating water, BS1 is used for general cooling, and BS2 is used for intermediate cooling. However, I don’t know the code for the refrigerant that uses ethylene glycol; I’m seeking an answer.
Yeah, that’s right. I haven’t found it either; I hope experienced sailors can give me some advice
