Compressed air dryers at high altitudes
Compressed air dryers at high altitudes
(OP)
I have a compressed air application in a mine at 15,000 ft asl. I got a table from Sullair with derating factors for screw compressors at different altitudes. At 15,0000 ft asl a compressor looses 46,8% of its capacity.
What I need to know is how to derate a refrigerant dryer for this application. Would the altitude affect the refrigeration circuit?, how can I understand what happens with the R134a refrigerant in the expansion, evaporation, compression and condesation processes?.
Your advise would be very much appreciated.

"Belief" is the acceptance of an hypotheses in the absence of data.
"Prejudice" is having an opinion not supported by the preponderance of the data.
"Knowledge" is only found through the accumulation and analysis of data.
